TRM Sill

TRM Sill is a “peel and stick” supplemental non-chemical termite barrier. It is installed directly on the concrete underneath the sill plate. It blocks entry of subterranean termites at this common entry point. It also acts as a barrier to moisture and energy leaks. 

TRM Sill can block entry at the exposed underside of the sill plate. TRM Sill comes in 66.7′ rolls, with roll widths of 6", 7", 9" and 12".

The use of a primer, such as Polyguard's 650 WB Liquid Adhesive, is recommended for superior adhesion of TRM Sill.
