Rainscreen Cladding Systems for Advanced Architecture
Correctly specified, a rainscreen cladding system will provide insulating properties whilst controlling water, wind, and fire. The primary driver for a rainscreen cladding system is usually down to the visual impact of the building. But the desire for aesthetics has to be combined with performance; waterproofing the building and contributing to the overall thermal performance.
Trends in wall cladding panels are changing rapidly insulation materials. As manufacturers of Ventilated Rainscreen Cladding systems continue to innovate with new technologies, types of insulation, and green building methods. Intelligent-based systems provide dramatic artistic effects for ceramic facades. And address environmental goals including protective layers from air, wind, water, and heat gain. The purpose of external Rainscreen Cladding is to shield wall insulation from direct rain. Hence protecting the fabric or a building while giving it a decorative finish.
Rainscreen Cladding has become very popular in the United States due to high performance and virtual free maintenance. At DUOMIT we have developed industry-leading expertise in designing and implementing rainscreen cladding solutions for our clients.
A rainscreen is an exterior wall detail where the siding (wall cladding) stands off from the moisture-resistant surface. An air barrier applied to the sheathing (sheeting) to create a capillary break and to allow drainage and evaporation.
A system is a form of double-wall construction that uses an outer layer to keep out the rain. And an inner layer to provide thermal insulation, prevent excessive air leakage, heat loss, and carry wind loadings. The outer layer breathes like skin while the inner layer reduces thermal conduction and energy losses. The structural frame of the building is kept absolutely dry, as water never reaches it or the thermal insulation.
Evaporation and drainage in the cavity remove water that penetrates between panel joints. Water droplets are not driven through the panel joints or openings. Because the rainscreen principle means that wind pressure acting on the outer face of the panel is equalized in the cavity. Therefore, there is no significant pressure differential to drive the rain through the joints.
During extreme weather, a minimal amount of water may penetrate the outer cladding. This, however, will run as droplets down the back of the cladding sheets and be dissipated through evaporation and drainage.
DUOMIT’s product range of external facade options ranges from simply recessed fix metal trays through to more complex systems. Pressed metal panels are available in fully secret fixed systems, utilizing either cassette or hook-on type joint details.
At DUOMIT we have worked hard to pass the stringent education and regulatory requirements. To become licensed Rainscreen Cladding Installers of the leading manufacturers. We can offer the best to our clients in New York.
Advantages of Rainscreen Cladding
- Thermal bridging is eliminated because there are no interruptions caused by floor slabs
- Temperature fluctuations are minimized due to insulation on the outside, prevents heat flow
- Interstitial condensation is prevented as vapor pressure and wall temperature restricts condensation to the ventilated cavity
- The heat from the sun is dissipated so that the high temperature is dispersed in the cavity and ventilated through openings
