What is a solid wall with rainscreen cladding?
The rainscreen cladding system is made with a bearing wall, an insulation layer and a cladding material that is fixed to the building using a supporting structure. Thanks to this structure, an air cavity is created between the load bearing wall and the cladding material, allowing continuous ventilation.
How thick is rainscreen cladding?
Panel Thickness: 40mm joint depth Panel Size: 3000mm module length X various widths up to 600mm maximum.
What is an open rainscreen?
“An open joint wood rain screen is a construction method that uses wood siding as the outer “rain screen” layer, creates a “wall cavity” (space between the back of the siding and the outer building envelope) and has an open joint in the wood siding to allow for ventilation.”
What is open rainscreen?
What is rainscreen application?
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.
How do you make a rainscreen?
To build a rainscreen wall, simply add space between your siding and your weather-proof barrier covered sheathing. The secret to a rainscreen wall system is the airspace separation between siding and sheathing. Traditional wall construction consists of an exterior siding (primary barrier) installed over sheathing.
What is Rainscreen cladding?
Rainscreen cladding provides an outer layer to the building that screens the rain down its surface. The joints of the system are often left open, to allow any excess moisture to pass through, and be drained down the cavity. The backing wall or frame is usually fitted with insulation with a water resistant layer to provide the weather protection.
How to avoid staining sills on Rainscreen cladding?
When working with openings to the rainscreen, in order to avoid staining sills are usually formed to direct rainwater to the sides of the opening and down the joints between panels, rather than directly down the face of the panel below. See below for some metal rainscreen cladding details examples.
How does a rain screen system work?
Rainscreen systems rely on ingress of air at the bottom of the cladding – a ventilated cavity not less than 38mm (to allow the stack effect to work) and egress of air (normally baffled to avoid rain ingress) at the top of the cladding. The majority of the water is kept out by the cladding material.
What is the minimum width of a rainscreen panel?
Air gaps should be adequately ventilated and the following minimum widths maintained behind all rainscreen panels: 50mm for panels with open joints, or 38mm for panels with baffled or labyrinth (rebated) joints. Open, baffled or labyrinth (rebated) joints should have a minimum 10mm opening, unless specified otherwise.
