What is the purpose of a rainscreen?
A rainscreen is an exterior wall detail where the siding (wall cladding) stands off from the moisture-resistant surface of an air/water barrier applied to the sheathing to create a capillary break and to allow drainage and evaporation.
Can Tyvek be used in a rainscreen?
An innovative drainage mat, Tyvek® DrainVent™ Rainscreen prevents the rot, cracking, and peeling that moisture can cause in exterior wall systems. Ideal for stucco and stone, DrainVent™ Rainscreen is effective in a range of building materials.
How do rain screens work?
In a properly designed rainscreen system, air continuously flows through the cladding joints and cavity, whisking away moisture. In a properly designed rainscreen system, air continuously flows through the cladding joints and cavity, whisking away moisture.
What is a building rain screen?
A rainscreen is the weather-facing surface of an exterior wall detail that stands off at least 1/8” from the moisture-resistant surface of the structural back up wall. The addition of a drainage plane mitigates the risk of moisture intrusion from unavoidable imperfections in the wall materials and construction.
What is a rain screen in architecture?
What is a Rainscreen? Rainscreens are time tested wall systems that have been in use for over a century. The rainscreen design is generally defined by the separation of cladding from a structural wall in an effort to manage moisture and energy transfer through a wall assembly.
Will Tyvek keep rain out?
Is Tyvek Homewrap breathable for home weatherization? Yes, Tyvek is made with unique material science to keep air and bulk water out while allowing moisture vapor inside walls to escape.
What is rainscreen furring?
A rainscreen is an exterior skin system made up of siding, an air gap via furring strips, WRB layer, and structural sheathing substrate (nowadays OSB or plywood). The siding sheds 90% or more of precipitation, but not all of it.
What is vented rain screen?
A vented rainscreen — an air gap behind the siding — has become a standard detail in many new houses. It helps remove moisture that works its way through the siding, and in the process helps siding last longer.
What is rain screen siding?
Which is the best rainscreen for exterior walls?
An innovative drainage mat, Tyvek® DrainVent™ Rainscreen prevents the rot, cracking, and peeling that moisture can cause in exterior wall systems. Ideal for stucco and stone, DrainVent™ Rainscreen is effective in a range of building materials.
How does weathersmart rain screen work with cladding?
Compatible with all cladding types, WeatherSmart® Rainscreen provides a 6mm gap between cladding and weather-resistive barrier, creating space for ventilation. The 3D matrix polypropylene strands channel water down and out of the wall assembly and the built-in fabric protects the gap from debris.
What kind of barrier does a rain screen need?
The air and waterproof barrier produces a highly durable, seamless, elastomeric weatherproof membrane on exterior sheathing behind open-jointed or vented rain screen cladding.
How does Rainscreen cladding differ from other wall constructions?
Rainscreen cladding systems differ from other wall constructions, as although the membrane is still fixed directly to the structure, it is situated behind the insulation. The material to specify is dependant on the risk of condensation at this interface, determined in the main by the temperature.
