What is the best way of achieving an air and vapour barrier when using Recticel PIR insulation panels?
Category: DIY
As per the literature supplied with the product - an effective air and vapour barrier can be achieved by the taping of board joints using suitable insulation tape, the inclusion of a separate proprietary vapour control layer or the use of a foil backed plasterboard all of these methods are acceptable forms of air/vapour control.
