Ventilated Facade Insulation: Materials and Thickness
Insulation behind a ventilated rainscreen facade is made with non-combustible mineral wool boards fixed to the wall with insulation dowels and, where required, covered with a wind barrier membrane. A ventilated cavity is left over the insulation to remove moisture, so the board stays dry and keeps its thermal performance.The main selection criteria are the density and intended use of the board (for rainscreen facades, not for rendered facades or roofs) and a thickness confirmed by thermal calculation for the specific region and wall. This article is useful for designers, clients and technical supervisors of multi-storey and public buildings, and for private home owners choosing an insulated rainscreen facade.The general logic of the systems is covered in the Ventilated rainscreen facades section.
