The Thin-R PIR Partial Fill Cavity Wall Insulation Board T&G 90x450x1200mm 4pk is a high-performance PIR insulation board designed for use in traditional masonry cavity walls. With engineered tongue and groove joints and pre-formed corners, it helps maintain insulation continuity and minimise thermal bridging, while retaining a residual cavity to provide protection against wind-driven rain.

Features & Benefits:

• Stable and rot-proof insulation that provides no food value to vermin and remains effective for the lifetime of the building (dependent on specification and installation).
• Robust tongue and groove jointing to support insulation continuity.
• Low emissivity foil facings help improve the thermal performance of the wall.
• Corner panels and cavity closers help reduce thermal bridging.
• Clear residual cavity maintained for protection against wind-driven rain.
• Reaction to fire classification - Euroclass F (Flammable)
