Are you after a highly versatile multi-purpose insulation board? Then have a look at this Celotex XR4200 insulation, which is suitable for multiple applications such as pitched and flat roofs and solid floors, masonry walls and timber and steel framed systems.
Made of sturdy polyisocyanurate (PIR), this Celotex high performance insulation is surprisingly easy to handle, cut and shape as you wish. You can fit it between rafters and joists for a highly insulating layer of insulation that's not too thick. This excellent insulation delivers outstanding thermal performance, with an impressive thermal conductivity of 0.022 W/mK which allows them to easily meet the required uValue.
Thanks to the low emissivity foil facing, thermal performance in sealed cavity air spaces is boosted, raising the potential uValue even further. Celotex XR4200 insulation boards are designed to Quality Management Standard ISO 9001:2015 and have a BBA (British Board of Agrément) certificate, giving you extra peace of mind. Additionally, they have a BRE (Building Research Establishment) Green Guide Rating of A, which will help improve your environmental performance. Altogether, this insulation board will give you substantial long-term energy savings.
