Find out moreAre you after a highly versatile multi-purpose insulation board? Then have a look at Celotex XR4200 is suitable for multiple applications such as pitched, flat and solid floors, masonry walls and timber and steel framed systems. Made of sturdy polyisocyanurate (PIR), it's surprisingly easy to handle, cut and shape as you wish. You can fit between rafters and joists for a highly insulating layer of insulation that's not too thick. These excellent insulation boards deliver outstanding thermal performance, with an impressive thermal conductivity of 0.022 W/m.K which allows them to easily meet the required U-value.
Thanks to the low emissivity foil facing, thermal performance in sealed cavity air spaces is boosted, raising the potential U-value even further. Celotex XR4200 insulation boards are designed to Quality Management Standard ISO 9001:2015 and have a BBA (British Board of Agrement), 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.
Question:
What is the the compressive strength of celotex xr4200/xr4000. The 200mm thick sheets. Will it easily take 100 mm concrete slab on top and floor traffic.
Answer:
compressive stress at 10% deformation* to BS EN 826 : 2013 - I will email you some links
Question:
We are hoping to use these boards as part of a set construction, and were wondering if the foil bit peels off at all
