The Unquestioned Termite Barrier for ICF Construction

TERM® Barriers originated as an effort to help the ICF industry. ICF structures have special water and termite barrier needs. Termites can nest below-grade. In fact, back in 1999 the Southern Building Code officials prohibited below grade ICF foundations “unless they were protected by a termite barrier”. Since then the residential and commercial building codes require special protection for residential and commercial ICF structures in “very heavy” termite infestation areas. 

ICF manufacturers and builders have been good customers for Polyguard since the mid 1990’s.

That was when Polyguard started to develop and test termite barriers. The results were encouraging. This led to a 2002 Southern Building Code evaluation (ES 2136) of Polyguard’s prototype termite barrier, and usage of the Polyguard waterproofing/termite barrier on hundreds of ICF projects across the country.

Fast forward to 2017. Research has continued with termite barriers, plus insect and other pest barriers, at Texas A&M, and now at other major universities. After 17 years of laboratory and field trials, our barrier has been evaluated as a Termite Physical Barrier System by the International Code Council. 

Polyguard’s barrier is now called TERM Barrier System. TERM is not just a foundation barrier; it now extends around the building envelope. And TERM protects the structure against both termites and a variety of insects and other pests.
