More and more people are now interested in knowing a lot about curtainwalls. After all, curtainwalls are not entirely new for today’s metal buildings. A lot of metal buildings that surround us in fact have curtainwalls to reinforce their structural integrity, more than just enhancing their aesthetic value. But of course, you might’ve already read the benefits of this metal building component and you don’t need added convincing. Right now, you are probably more concerned about which type of curtainwall will best suit your metal building.
Stick curtainwall systems are essentially made-to-order parts, which are shipped ready for on-site assembly. The parts of the curtainwalls may be delivered in a pre-defined or “stock” length. For this case, not just the assembly but further cutting and machining will be done on-site. On the other hand, the curtainwalls may be delivered knocked down, just like your average personnel door ,for metal buildings, as an example. This latter case will require only assembly and sealing once delivered.
Stick systems are glazed on-site or “field glazed” and are therefore only turn out to be as good as what the environment allows. The weather, dirt, and dust in the field largely affects the overall performance of the curtainwalls in the long run.
Unitized curtainwalls are basically just “uniform sized” pieces. This type of curtainwall system is typically found in metal buildings that are more inclined to give off geometric symmetry, as this type is excellent in giving this aesthetic effect. Unitized curtainwalls are installed piece by piece, level by level, starting from the bottom of the building. Unlike the stick system, unitized curtainwalls are pre-glazed before shipment. In terms of performance, unitized curtainwalls are better than stick systems when it comes to water resistance. But for the rest of the features, the two types are fairly level.
For some people, storefronts are considered the low-cost alternative to curtainwall systems, particularly for low-rise commercial metal buildings. Although compared to the two types previously discussed, the water resistance test pressure and air infiltration values for storefronts are also lower. Following this, storefronts require more maintenance than curtainwalls, especially because this type is widely used for commercial, high-use applications.
As a final note, customization is still not out of the picture. There are several types of curtainwalls and also alternatives, such as storefronts, which may also serve the purpose that you need. It is important that you consider your constraints, such as time and money, in order to define which option is the best for you. And when in doubt, you can always consult an expert to help you decide.
