Heat Sheet R4

Heat Sheet R4


The Heat Sheet is a rigid foam insulation board that has nodules to hold your in-floor heating pex pipes. So you literally step the pex pipes into place.

This replaces the standard pink foam insulation board that you typically would staple pex pipes to.  It also replaces the staples. You may still want a staple or something at the curves in your pex pipes.

The Heat-Sheet R4 is available in the 1 3/8″ ” thickness, R-value 4.

Usually ready in 24 hours
