Celotex XR4150 in 150mm is an economical and accessible board. It is easy to manipulate and to put in place, either in both pitched roofs and flat roofs, as well as floors or walls. Its main purpose is to get rid of thermal issues, such as loss or accumulation of heat. Since it is prevalent in a large number of homes, a lot of professionals in the building industry would have worked with this board beforehand and will know how to install it regardless of the specified application.

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.
