The Gyproc ThermaLine PIR is a high-performance polyisocyanurate foam insulant with two integral vapor control layers to reduce the risk of condensation.
Designed to be used in both refurbishment and new build for ceilings, walls, areas in the roof and window reveals where high-level thermal insulation is required to reduce heat loss from buildings.
The double vapour barrier also helps to reduce the risk of structural damage as a result of damp or mould.
