Celotex XR4000 Insulation Board 1200mm x 2400mm x 130mm

XR4000 is a rigid polyisocyanurate (PIR) insulation board with high thermal performance. Available up to 200mm thick, low U-values can be achieved without doubling-up insulation layers. Celotex boards are lightweight and rigid; making them easy to handle, transport, and fit on site, and suitable for applications including: ● Ground floors – whether solid concrete, block and beam, or suspended timber joist, and including where underfloor heating is used. ● Timber and steel framed walls – between the studs. ● Pitched roofs – between the rafters. ● Flat roofs – in ventilated cold roof constructions, installed from inside the building. ● Other retrofit and refurbishment projects – lining existing timber and masonry structures to make them more thermally efficient.

Celotex TB4000 Range Insulation Board 1200mm x 2400mm x 130mm

TB4000 is targeted at cut-to-fit applications between rafters or joists and enables users to achieve lower U-values with a single layer of insulation than has previously been possible. It is also appropriate for use in floors and walls. With low emissivity foil facings, TB4030 is manufactured from rigid polyisocyanurate (PIR) using a blend of blowing agents that have zero ozone depletion potential (zero ODP) and low global warming potential (GWP).
