50mm Insulation Board

About

Why 50mm Insulation? 50mm is one of the most widely specified rigid insulation thicknesses in UK construction and it works across an enormous range of applications. At this depth, PIR boards start to deliver the thermal resistance needed to make a real contribution to meeting Part L of the Building Regulations, which sets out the minimum energy efficiency standards for new builds and major refurbishments in England. That makes 50mm the standard starting point for most wall, floor and roof insulation projects, whether you are building from scratch or upgrading an existing property. Here is what the range covers: PIR boards at 50mm achieve 0.022 W/mK thermal conductivity, suitable as a primary layer for walls, floors and roofs or as part of a multi-layer build-up Phenolic boards outperform PIR with a lambda as low as 0.019 W/mK, the right choice where build-up depth is tightly constrained and U-value targets are demanding EPS boards offer cost-effective performance at 0.038 W/mK for ground floors, external wall insulation systems and below-ground applications XPS boards deliver high compressive strength and negligible moisture uptake for inverted roofs, basements and heavily loaded floor slabs 50mm PIR Insulation Boards PIR is the most popular choice for 50mm rigid insulation in the UK. Foil-faced, lightweight and easy to cut, PIR boards at 50mm are suitable for solid and suspended floors, framed wall systems, pitched roof applications between or below rafters and flat roof build-ups. All boards achieve a thermal conductivity of 0.022 W/mK. Celotex GA4050 The Celotex GA4050 is one of the most popular 50mm PIR insulation boards in the UK. A multi-purpose board suitable for walls, floors and pitched roofs across domestic and commercial projects, it is BBA certified, simple to install and one of the most competitively priced options in the range.
