Fundamentals of Curtain Wall Systems

Curtain Wall systems are defined as thin materials with aluminum frames and contain in-fills of delicate stones, sheet metals, and glass. The mainframe is bonded to the base structure, and it does not carry the load of the building's roof or floor. The curtain wall supporters transfer the force caused by wind, gravity, and other environmental factors to the construction's floor line. Curtain walls were created for military purposes. However, after the growth of technology, construction builders began utilizing them for residential and commercial purposes.

Fundamentals

Curtain walls bring many benefits and advantages such as thermal performance, moisture protection, aesthetic, etc. However, they are also classified by their fundamental properties. Knowing these properties can help the building owner in utilizing the most efficient wall system for the facility.

Forms of Curtain Walls

There are three main curtain walls available in the form of rain-screens, face-sealed, water managed and pressure-equalized. The pressure-equalized product is generally the ideal type of curtain wall, which provides higher weathering, air and water infiltration resistance with their unique water-managed systems.

The pressure-equalized wall systems prevent water infiltration across the barrier with their functionality, blocking almost every force that can cause the liquid penetration. PE screen systems are utilized to design the inside surface of the curtain walls, glass or pocket. The airtight barrier of these products is generally created from a wet sealant or an interconnecting gasket

The most effective portion of curtain walls that work as a rain-screen is the exterior glazing materials, outside face of glass, and the frames outer exposed surface, which is made from aluminum plates. Manufacturers form a PE chamber between the interior air barrier and the exterior raining screen in the glazing pocket. This portion reduces the water infiltration by equalizing or eliminating the pressure difference across the panels that tend to push the water inside the buildings structure or the curtain system. However, it is very typical to witness a minor amount of water to penetrate the system, typically wiped to the exterior without causing any damage.

The Water-managed system is almost similar to the PE system at first glance. This system incorporates weeps and drains from glazing pockets. However, there is no effort made to place an air barrier on each glass or spandrel unit. Thus, a more considerable amount of water will infiltrate the aluminum curtain wall system, which should be wiped away. The pressure difference, which is strong enough to force the water to reach a higher position vertically than the internal gaskets, is due to the absence of air barriers resulting in higher leakage. Pockets and holes in this system have high functionality in draining the water that infiltrates the structure.

In contrast, in PE systems, holes function as vents for allowing air movement between the glazing pocket and the exterior wall. The best way to recognize the PE system is to determine that if the pocket around each unit of glass isolated airtight or not. This characteristic can be detected by finding plugs or seals at the gap between screw splines at joint intersections

Some industrial manufacturers prefer to design aluminum curtain walls in face-sealed systems. Their functionality depends on the quality of sealing between the glass units and the aluminum frame or all frames members perform in the application. The long-term usage and reliability of these seals are not safe, and avoiding utilizing them is recommended.

Support of Curtain Walls

They are two types of supporting curtain walls available in the market: stick-framed and unitized systems.

Vertical mullions run pas two floors in the stick-framed systems, usually combined with gravity anchors on the same floor. In some cases, a lateral anchor is used on another floor to increase the support. The splice which exists in between the vertical mullions is designed to provide lateral resistance and vertical movement. In larger scales of this type of support, split vertical mullions are used periodically to provide thermal activity. The glass movement, which takes place within the frame, and the anchors' involuntary movement tend to persuade additional stresses into the stick-framed method.

Unitized curtain wall systems incorporate the differential movement between the frame's thermal movement at the joints of each curtain wall and the structure. Due to these products' customizable characteristics, the amount of action needs to be engineered very precisely. Anchoring and attaching unitized systems involves a proper assembly with three-way dimensional adjustability. There is an existing stack joint in curtain systems that are designed to increase the lateral load resistance, while the two-floor anchors are both utilized for lateral and gravity resistance improvement.

Fire Safety

Curtain walls contain gaps between the floor edges and the back of their structure for slowing down the passage of combustion gases and fire between different levels and floors. For ensuring fire safety, the product must be approved by being tested in fire-rated assemblies. The PFCS needs to be equal to or more significant than the flooring rate. Firefighters who try to extinguish the flame require venting and emergency access, which the curtain walls provide. This specific characteristic is known as a knockout panel. It can be identified by a non-removable reflective dot, which is generally located in the lower corner of the opaque or glass.

Maintenance Access

Curtain walls are designed in a way to provide accessibility for maintenance purposes. Maintaining buildings with low latitude is more comfortable due to the accessibility of equipment that has articulated arms. On the other hand, high-rise buildings need to be designed for swing stage access for general maintenance, repairing, and window cleaning.


Advantages of Curtain Walls

Curtain walls are products, which are developed having a thin thickness and are usually made from aluminum frames while containing fills of metal panels, delicate stones, or glass. The frame is generally bonded to the construction’s structure; thus, it does not carry the load of the roof and floor of the building. The load caused by environmental factors such as gravity and wind is typically transferred to the structure's floor line. This product development started in the 1930s, and the manufacturing services expanded rapidly after World War II. It was first utilized for military purposes, and then designers turned it into a suitable exterior product like other industrial materials such as ACP.

Architects and builders use a wide range of curtain wall systems to specialize in custom walls. These products have become a cost-effective solution and a strong competitor to other standard walling systems.

A Brief Description

Curtain wall systems are classified by their installation and fabrication methods into two main categories, which are unitized and stick systems. In the stick system, the frame and opaque or glass panels need to be connected piece by piece, and then the installing process must be completed afterwards. On the other hand, curtain walls that follow unitized systems are composed of large units glazed and assembled in the manufacturing factory and then shipped or transported to the construction site. Adjoining modules attach the vertical and horizontal mullions together. These modules are generally created with a longer length and are often five to six feet wide.

Another method for classifying curtain walls is considering them as pressure-equalized or water-managed systems. All types of these walls are designed for both interior and exterior glazed systems. Interior systems are used to allow the opaque or glass panel to be installed into the wall opening from inside the building. Due to the air infiltration issue, the interior glaze system does not provide details. It is suitable for applications with limited inner obstructions for providing adequate access to the inside of the wall. Outside glazing is specified for low altitude buildings with easy access to the construction.

In some specific cases, the interior curtain type is used for high-rise buildings to provide glass replacement logistics from a swing stage. Glass panels need to be installed from the outside of the wall in exterior glaze systems. These systems require scaffolding access to the outer space of the wall for replacement and repair purposes. Some of the designs can be glazed from both interior and exterior areas.

Glass panels used in curtains are predominantly insulating and are usually fixed or glazed into operable frames placed in the wall system. Metal panels are varied in aluminum plates, stainless steel, or other corrosion-resistant materials such as aluminum composite panels created from two sandwiched layers. Panels that are made from stone substances are usually granite.

Beneficial Characteristics 

Curtain wall systems provide many advantages for any construction project. Thus their popularity is still growing day-by-day. Determining these products main benefits can help architects and building owners create their unique and efficient facility. Followings are the most beneficial characteristics of Curtain walls.

Back Pan Insulation and Thermal Performance

Back pans are metal sheets, which are usually made of aluminum or galvanized steel. These sheets sealed when attached to the curtain wall framing. They act as an air and vapor barrier when the insulation is installed between the exterior cladding and back pans in colder climates. They also create an additional defense against infiltration for areas that are not easy to access. Curtain walls are trendy for their high thermal performance. This is due to the conductivity of aluminum. It is common to use thermal breaks of low conductivity for improving the performance of these products. They can prevent the heat infiltration and save a tremendous amount of energy. This is due to the presence of an extra layer across the building. Thus, these type of walls can stabilize the overall temperature of the building. Additionally, UV light, which can increase the pace of fading or degrading the building, can be significantly reduced by curtain walls.

Water Penetration and Condensation Resistance (Moisture Protection)

Water penetration resistance of curtain walls results from glazing details, drainage details, frame gaskets, weather-stripping gaskets, interior sealants, and flashings. Water can penetrate through the building's exterior cladding system employing five important forces: kinetic energy, gravity, air pressure, capillary action, and surface tension. To decrease the water penetration, these forces should be considered in the building’s design. Curtain walls usually cover large areas of the wall without flashings, and this makes them a better choice compared to small and discontinuous windows.

Visual Aesthetics

Sightlines and glazing appearance of curtain walls is the key feature of these products. Visual profile of the horizontal and vertical panels are defined as sightlines. They create both the width and depth of the curtain wall frames. Most modern buildings require curtain systems due to their unique, clean, and sophisticated appearance. The installation systems for these beautiful products are commonly better, faster and more cost-effective than other cladding products.

Sound Insulation

 Another function of the internal seals used for preventing air leakage is the acoustic of curtain walls. This characteristic can be improved by installing sound attenuating infill. The incorporation of glasses with different thicknesses will also help in exterior sound deadening. This is achieved by increasing the glass or opaque thickness or utilizing a laminated layer with an interlayer, which has noise-reduction specification. These layers are typically made of PVB or polyvinyl material.

CNC Router for Aluminum

Most people thinks that machining metals such as Aluminum should involve the usage of high-end milling machines that can carry out extremely complicated work. There is no denial that spindles of these machines can spin their cutting tools at a speed comparable to the best drills. However, the CNC router provides spindles that can operate and rotate at a higher speed than the regular mill.

Is It Possible to Cut an Aluminum Material with a CNC Router?

Machining materials such as Aluminum with a CNC router is possible with most of the CNC types. The material can be easily cut by matching the right feed rate and end mill bit with its properties. It is essential to consider that cutting process is about separating aluminum sheets by cutting them into pieces and making pockets and holes into aluminum plates. This means that the CNC router can remove desired material parts from both plates, sheets, and create products such as perforated panels, aluminum composite panels for cladding, etc. It is just about the right way of using the end mill cutting bit.

While cutting Aluminum products, it is important to have in mind that the procedure is not as same as plastic or woodcutting. These materials have smaller sweet spots for optimal feeds and speeds. This means that the cutter tool can break if the sweet spots are left out fast and can cause a poor surface finish. There is another important factor when it comes to using a CNC router for cutting Aluminum, which is called the stickiness factor. This material is a kind of metal that tends to stick to the cutting tools. This almost happens on the point where it welds itself to the tool. Once a gummy aluminum deposit is created on the cutting edges, the tool will no longer be usable. This is especially essential if the rotation rate is fixed on 20,000 RPM or more.

How to Manage Cutting an Aluminum Using a CNC Router?

As it is obvious, cutting aluminum has its unique complexities. It is not as same as the wood and precision for certain aspects is the key to obtain the best results. The first important thing to have in mind is taking the procedure slowly. The goal for most industrial cases is to complete the job with speed and quality. This does not apply to this type of machining process. When using a CNC router for an aluminum product, steady and slow removal of desired material is the main goal.

The next important step is choosing the right router bits and small diameter cutters to obtain better control over the product and gain higher precision on the process. Using two or three flute carbide end mills is suggested due to their ability to have greater spindle speed on the machine. When working with aluminum sheets, HSS and cobalt cutter are not required. Small tools often work better for this material. Aluminum is a soft metal; however, the cutter can be easily broken during the procedure. The 1 flute end mills which are popular for plastic will not overcome the job pressure. Since the aluminum material tends to friction weld itself on the cutter, it is recommended to have a smooth surface finish to reduce the possibility of potential damages. Another important note is that the operator must remove the produced chips very fast because they can break the expensive router bits because of being recut. This process must be continued until a high-quality result is achieved.

Rigidity is another important factor when it comes to cutting aluminum with a CNC router. Small routers and large professional industrial machines definitely have differences. Aluminum is a material, which requires more rigidity than wood and plastic. Using tools that have longer bits can increase the advantage of the workpiece. When buying bits, it is important to keep an eye out for end mills that have stub ends and they should be kept short in the collet. Some manufacturers use aircraft cable and steel pulleys to add extra tension to the bridge and some others add extra ball screws and bearings to enhance their machine’s rigidity.

Another important step is to calculate and utilize the suitable and right feed rate to achieve better results. Predicting and calculating this can be very challenging. However, they are some starter standards that utilizing them can help to find the optimal feed rate in a short amount of time. For example, the cutting speed for aluminum in the case of the carbide tool is about 1,500 surface feet per minute at the highest point, and 1,000 at the lowest.

AS told the Aluminum metal has stickiness factor in its physical properties. The stickiness of the material can be controlled by putting it in oodles of lubrication. Some manufacturers recommend using oil mist as a lubricator. If an upgrade is required, then installing one is definitely recommended. It is not hard to install and it only needs a kit, compressed air, and oil. However, they are other alternatives available for the purpose. One of the most common systems is using lubricant sprays. This system can be challenging for machines that have a downward exhaust. In this type of routers, tons of air will be blown around the tool without actually reaching the cutter. It can be very tricky to have perfect spraying around the air blast. Another method is using cutting wax, which can be applied to the cutting surface. Using this method can solve the issues for downward exhaust machines and works perfectly for the process that requires single or shallow Z depth. If the routing needs more depth, it is recommended to get the lubricant further down by reapplying it in the recent cut channel.


What are The Types of Welding Systems?

Human has been welding pieces of metal together to create new products for centuries. Today, our race has achieved vast knowledge of the process and has expanded the techniques and applications equivalent to the modern era. For people who tend to enter the welding industry or need to buy welded products, knowing the definition of the process, types of it, and the purpose of each can be very helpful.

What is Welding and Why Manufacturers Use it?

Welding is one of the metal fabrication procedures in which high temperature is used to melt and fuse pieces together. However, in some cases, pressure can also be used additionally to provide a weld. It is eminent from lower metal fusing methods like soldering or brazing, which do not usually melt the base metal. There are other fabrication methods along with welding, which are commonly used, such as laser-cut, bending, shearing, and notching.

All types of Welding systems usually involves the use of a material called “a filler” or “a consumable”. This is used to provide a filler or pool of molten material that helps smooth the formation of a strong bond or link between the base metals. Most of these fabrication processes will require a shielding coat to protect both main components and filler from being oxidized during the procedure.

Metal Welding can be performed utilizing various forms of energy sources. These sources include a gas flame, laser, an electric arc, an electron beam, ultrasonic, and friction. Some of the welding methods can even fit underwater and space settings.

Types of Welding

More than thirty types of welding processes exist in the sheet metal industries. They range from simple oxy-fuel to modern and high-tech processes such as laser welding. However, they are some a few of these techniques, which are commonly used for the process. Each of them come with their special characteristics and advantages. Followings are the most popular welding techniques utilized in the industry.

MIG – Gas Metal Arc Welding Known as GMAW

This type of welding is done by continuously fed of the electrode through a welding gun. The expert or operator should pull the trigger to feed the consumable through the certain joining part. Between the base metal and the electrode, an electric arc forms which heat the metal until it reaches or exceeds its melting point property. This type requires an extremely supplied shielding gas. Some of the most common gases for the purpose are carbon steel, stainless steel, copper, aluminum, and silicon bronze.

The most important advantage of using the MIG method is waste reduction. These types of welding systems results in the minimal cleanup, lower heat inputs, and fume reduction. Additionally, it is the easiest technique to learn and is suitable for beginners.

MIG system is commonly found in automotive industries due to its strong weld characteristics, which can withstand large forces. When it comes to MIG welding, the operator needs to be precise about the power setting adjustment to have an appropriate thickness result. The speed of the process also affects the penetration of the weld. By decreasing the speed, the penetration will be increased.

TIG – Gas Tungsten Arc Welding Known as GTAW

TIG is another type of welding process in which a tungsten electrode is utilized that is not for heeding the base metal but for creating molten puddle for the joint. In this method, external gases such as argon and argon/helium mixtures are required. The most common applications for TIG systems are piping, tubing, aerospace, and motorcycles.

The greatest advantage of this technique is allowing the operator to weld very thin materials while having-high quality cleaning and highly aesthetic joints. Thus, this type of welding system is the most popular type of all in the current industry. It is generally utilized for applications, which involve metals such as stainless steel, aluminum, and copper.

Stick – Shielded Metal Arc Welding Known as SMAW

In the SMAW method, also an electrode is used to carry electric current. The electrode that is utilized for this system consists of a core wire that is coded. The electric arc is created as soon as the tip of the electrode makes close contact with the base metal. As the procedure starts, the joint part exceeds 6500-Fahrenheit degrees. The molten material is protected from oxides and nitrates that exists in the atmosphere during the process. Thus, this type of welding is suitable for the pipeline, construction or cladding, heavy equipment repair, and steel erection.

This welding method allows the customer to gain results with low cost of equipment, which are also portable. There is no need for shielding gas in the STICK method. This means that experts can use this system in open-air even during rain or wind. Additionally, this technique can be utilized on dirty and rusty metals thus it is an appropriate alternative for projects where using TIG or MIG is not required.

Flux – Core Arc Welding Known as FCAW

This welding technique is very similar to the MIG method. However, instead of solid wire, it requires a tube-shaped wire, which is filled with flux. The most noticeable advantage of this method is the electrode efficiency, which means less waste creation. With the use of this system, there is no need for utilizing external shielding gases and it provides welding fumes reduction regardless of the metal that is used for the process.

FCAW method is very easy to learn and many professionals prefer to use this system due to its extremely inexpensive benefits. On the other hand, there are some limitations when it comes to having aesthetic results.


CORTEN Steel Sealing Method

CORTEN Steel which is also called COR-TEN or weathering steel is one of the most popular materials in building and construction industry. The COR part of the word refers to metal’s property of corrosion resistant and the TEN denotes the material’s tensile strength. This material is very applicable and widely used in landscaping, exterior cladding and other outdoor applications such as garden sculptures, stairways, artificial fountains, storage etc. This product is a steel alloy which contains zinc after having galvanization process.

This material is perfect for creating an architectural masterpiece for roofing and cladding projects and it can allow the designer to combine the best of the old with modern innovation and create something extremely aesthetic. COR-TEN offers an age-old rustic look which can add stunning contrast to the appearance of the building. This cladding material is extremely robust metal which provides high structural strength despites its thickness which is ¼ inch. In addition, it is a lighter weight material and need lower maintenance in comparison to other metal materials in market. The texture, color and its specifications quality such as having ability to be bent, laser cut and weld, make it suitable for any application which demands a spectacular and unique visual statement. From gardens to office buildings and mentions or holiday homes, this material can deliver function and image in one package.

CORTEN Steel has the ability to form a protective layer of rust after being exposed to moisture, humidity and oxygen for approximately six months. Since the created rust layer protects the material from the further damage and corrosion, additional painting or weatherproofing is not required. In addition, this ability can bring unique and rustic look to the cladding. It is important to note that in order to have this protective layer, this steel requires exposure to wet-dry cycles. If this material is buried in a wet grounds or submerged in water, it cannot form the additional rust layer. Areas which are close to ocean may also prevent the forming of the protective film. However, the anti-corrosion characteristic of this material is superior to those of ordinary and general steels in many applications including industrial projects exposed to exhaust products from fuels which contain Sulphur or scaling at high temperature.

Sealing CORTEN Steel

There are variety of CORTEN steel profiles available which include interlocking panel, standing seam, traditional corrugated and snap lock. These cladding profiles are strong architectural lines which are very eye catching with their rich earth colored patina. There are other industrial products which are made from this material such as CORTEN plate, flat sheets, coil, flat bar, tube, pipe, angle, channels, beams, perforated panels etc. However, in some cases, sealing CORTEN steel will be necessary in order to avoid extra damage and expenditure. Here are the important things to know about corten steel sealing method.

  • Finding the best coat sealant which is compatible with the CORTEN steel is the prior task to do for both small residential and big commercial facilities.
  • Clearing sealants are not 100% accurate sealer. It is a fact that this steel is a natural weathering metal, however it does always react differently depending on many factors such has batch, profile, thickness, shape of fabricated item, location in which the façade is installed, chemicals or residue on the existing sheet, the time period in which the sheet has been weathered before clearing apply and many other.
  • Using a clear coat sealer which is utilized for numerous times on screens, claddings and other fabricated product and has very high success rate and other costumer’s satisfaction is recommended.
  • As a standard corten steel sealing method, all CORTEN products must receive a minimum of one or two coats. This depends on the factors which were told earlier.
  • Each coat of applied clear adds extra protection to the CORTEN steel panel. This definitely increases the limitation and elimination of the rust run off and leach. Thus, in areas which have high humidity level, adding more than two coating layers could be helpful. In general, each layer of clearing material cause additional cost once the standard amount of coats has been already used.
  • Every time a coat of clear is utilized, the CORTEN Steel will change it colors and will appear more dark. It can even have brownish or reddish, as opposed to the powdery orange color finish.
  • It is important to have in mind that once this steel is sealed, it will not weather anymore and it will remain the way it is arrived.

These panels are indirectly bonded in hidden areas. This ability allows the designer or architect the required freedom to create different stylistic aspects when it comes to using cassette system. These products are often produced in a way to have 25 millimeters of depth and a specified shadow space with 20 millimeters diameter. Shadow gap values are mirrored with a rail, which is suitable for fastening and is considered as an important part of forming the system. These panels are especially appropriate for external claddings which need length of up to 3.000 millimeters. In addition, façade grids will be chosen and installed depending on the taste, need and demand of customers.

Installation System of Cassette Panels

Installation system of cassette panels demands to have predefined positions of the elements which are going to be utilized in the structure’s frame-work. During frame-work procedure, exact measurement which includes width and center to center height and amount of panels which should be utilized must be defined. In general, cassette panels contain an upstand at the one end which is attached and fixed to the framework with clips and the other end has another up-stand which locates into the clips on the previous surface. Slotting is required for panels which exceed 1.5 meter in length due to need of expansion tolerance. Clips which are utilize for fixing the products need to be designed and tested in a way to have compatibility with the performance basis of the project and the specific application. These fixing materials are dual functional. These two functions are about ensuring the lift up resistance and providing free space for expansion to the cladding and the panels.

These metal wall panels bring unlimited installation options due to their solid aluminum based structure in comparison to other sheet metals with composite core. Opposed to other metal systems, aluminum plates are weld-able, thus different aesthetic shapes can be fabricated an attached in order to fulfill any design, which is desired. These aluminum products often have post painting procedure and lower paint cost before being available in market, thus they are budget friendly materials for the building owner who does not consider having high expenditure. They are unlimited color options available for the material and this makes the product exceptional to be utilized for exterior design.

Aluminum Plates Important Features

Thermal Movement for Attachment System

Aluminum plates start to expand or contract when exposed to climate or seasonal weather conditions such as frequent change in temperature. For example, the material will have approximately 3mm length expansion or contraction in temperature range of -20 to 30 degrees. This factor should always be considered before installing building claddings. Thus, aluminum plates have the advantage of being installed in way that expansion and contraction problem will no longer be an issue. This means that the plates are placed next to each other with a small amount of gap in-between to prevent the cladding from having any thermal movement problems.

Replacement of Single Panel

When it comes to external wall cladding, considering changing a specific panel due to damages caused by light, dust etc. is common. These damages are avoidable with proper and simple maintenance process, which should be done regularly. However, many building owners choose to replace some of the panels for changing the aesthetics of the facility. This is often about using another plate, which has different color. Aluminum plates have the ability to be changed in specific area and portion without requiring complete renovating procedure.

Easy Maintenance

It is obvious that every product need to have appropriate maintenance in order to maintain its quality during lifetime. Thus, this is considered as one of the most important and inevitable expenditures of a building. However, Aluminum plates have the ability to be cleaned and maintained with easy procedure at the lowest cost in comparison to other materials available in the industry. Cleaning these products is challenging only for high-rise buildings. The challenge is just about the number of working specialists and high-tech equipment for reaching all portions of the cladding.

Long Lasting

Aluminum plates are naturally long lasting materials. However, applying different types of finishes can increase the lifetime of the material. One of the methods available in industry is mechanical which includes polishing, buffing, grinding and sanding and improves quality of the surface. This method is also used for other cosmetic finishing preparation. For giving a mirror or specular finish to the product, bright dipping method is commonly used. For applying additional protection to the existing film, an electrochemical process is done on the material, which is called “Anodizing”. The most common finish in industry is liquid paint, which is coating and giving a uniform film thickness and special characteristics to the product.

Fire and Water Resistant

Aluminum plates are waterproof and fire resistant. Thus, they are ideal for high-tech and modern buildings, which require safety standards and are built in humid areas. Being waterproof makes the product suitable for making rain screens. Fire is one of the oldest threads existed for buildings. Aluminum plates have the ability to prevent the fire from spreading over the portions of the building. Thus, these materials are helpful in extinguishing fire and preventing the damage, which can be irreparable.

Wet joint System

Aluminum plate systems have wet sealant in the joint which is offering additional water penetration protection with special conditions. This increases the water resistant ability of the product and the lifetime of it. It also good to know that panel system types are determined by the joint method, which is used in installation process
