150mm Celotex XR4150 2.4m X 1.2m | Celotex 150mm

Celotex insulation boards score impressive thermal performance without losing efficiency through the years. Its sturdiness and unbending qualities mean it will keep spreading energy savings for a long time after installation. It is a thick PIR insulation that is easy to cut  and fit between rafters & joists, allowing to reduce the U-Value beyond what was possible to achieve with only one sheet of insulation.  

Celotex XR4150 is a PIR insulation board manufactured under high supervision with zero ozone depletion potential and low global warming potential blowing agents. Like all Celotex products, a great deal of care was put into meeting BRE Global Green Guide standards, hence contributing to lower harmful emissions caused by everyday running of most commercial or domestic space.
