First of all, ensure that the PIR insulation boards are laid above the damp proof membrane (DPM). The foil facings of our PIR insulation boards may be damaged by wet screed or wet concrete, allowing gas to escape that may weaken the floor topping so we would always recommend a membrane be used for protection over the PIR insulation boards once they have been laid & prior to the screed or ...

Scam artists have been known to warn builders that "mass insulation is transparent to radiant heat." The implication is that a layer of aluminum foil is necessary to prevent radiant heat from traveling like radio waves right through a deep layer of cellulose. In fact, most mass insulation products do a good job of stopping radiant heat flow.

The Physics of Foil There are three modes of heat transfer: conduction, convection, and radiation (infrared). Of the three, radiation is the primary mode; conduction and convection are secondary and come into play only as matter interrupts or interferes with radiant heat transfer. As matter absorbs radiant energy, it is heated and a gradient temperature [.]
