Rain Screen Design

Practical, Effective Moisture Management

Rain screen design provides a cavity between the exterior cladding and main structure of the wall.

  • Cavity allows for free drainage of any water that may penetrate the cladding.
  • The air space promotes rapid drying of substrates and cladding materials, inhibiting moisture penetration into the building envelope.
  • Ensures pressure equalization across the cavity to prevent water being drawn into the building itself.


VaproShield offers three easy and cost effective ways to create a rain screen design.

shims VaproShim SA Self-Adhered is simple, cost effective and creates an unimpeded drainage plane behind the cladding.

WrapShield RS Rain Screen offers one step installation of a WRB/Air Barrier and a rain screen cavity. It is ideal for use with cementitious cladding types.
