Rainscreen cladding works to keep structures dry while also adding an attractive element to the exterior. They allow air to move through to ventilate an area, but most of the moisture that strikes the façade is kept out. The small amount that does come through is easily dried, and that makes this a popular choice for buildings all around the country that are in areas that see high levels of rain or snow.
Two Layers Offer More Protection
The first layer of the building is the structural layer that also insulates and building and keeps it dry. In past construction, this was the only layer of protection, and water that worked its way behind the siding could cause problems with rot and mold. Modern construction methods are adding a second wall. Rainscreen cladding is decorative and adds visual appeal to the structure, and it also serves an important purpose by keeping the interior wall dry. A ventilated air cavity allows moisture that does come through the rainscreen to dry efficiently, and that protects the structure from the damaging moisture. It’s a more sophisticated approach to moisture control, and it’s one of the most effective options on the market today.
Rainscreening is made from metal because of its light weight and malleability. The metal is very durable and can withstand years of abuse from the weather. Manufacturers like Wade Architecture offers rainscreen cladding made from aluminum, copper, zinc, stainless steel, galvanized steel, weathering steel, and special alloys that are designed for exterior use and made to withstand the elements.
The Cost of this Coverage
The cost of this cladding is surprisingly affordable when builders stop to consider how it improves a building’s performance against wind and weather. It makes structures more durable, prevents problems with condensation and mold, and even makes the building more energy efficient by dissipating heat from the sun. The use of these systems won’t add too much to the expense of a project, but they help buildings last longer and reduce maintenance costs over the coming years.
Ideal for Managing Moisture
Areas along the coast and regions that see heavy rainfall deal with more problems from moisture. Investors who are building in these areas should strongly consider rainscreens to help protect their structures and lower maintenance costs over the long-term.
The Perfect Solution for Some Architectural Styles
Another problem comes from buildings that have tall walls and narrow overhangs. Wind-driven rain can be forced behind siding and result in rot and mold. Buildings that are short with wide overhangs don’t have this problem. This is why rainscreens are commonly seen in commercial structures that are very tall with minimal overhang. The rainscreen protects the structure from wind-driven rain when the overhang does not provide the right level of protection. Brick veneer is particularly vulnerable and can benefit from the protection of a rainscreen.
Lower Energy Bills
Those living in hot, dry climates can also benefit from a rainscreen as it serves to help shade the structure and dissipate heat. Rather than letting the heat migrate into the structure, it moves through the gap and won’t transfer inside. This helps people in hot areas to lower their cooling bills in a safe, natural manner. There are many benefits to using rainscreen in new construction. It can be used to add to the visual appeal of a building, and it provides superior moisture control and helps control heat in the summer. These systems make buildings more durable and allow property owners to enjoy reduced maintenance expenses by keeping the water safely away from the structure. They’re affordable, and owners find that they’re highly effective at moisture control.
