Application video for TERM® Foundation Barrier for ICF
The subject of this video is the installation of TERM® Foundation Barrier for ICF walls. TERM® Foundation Barrier is a non-structural barrier which when properly constructed as part of the building envelope, blocks both termites and water. TERM® Foundation Barrier is a strong, pliable, self-adhesive sheet made of a 4 mil high density polyethylene film integrally bonded to 64 mils of barrier sealant. Total thickness is 68 mils.
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.
TERM® Barrier System
The TERM® Barrier System, built in during construction, blocks entry of termites and insects into the structure. TERM® Barriers consist of waterproofing membranes with a sealant which has been upgraded to act as a physical and non-chemical barrier to termites and insects.
100% of the ground level slab surface must be protected, because concrete joints, cracks and future cracks, plus other gaps, provide insect entry points. 100% horizontal protection can be provided by installing TERM® Underslab Barrier below the slab, OR on top of the slab using TERM® Sill Barrier tied into TERM® flooring underlayments. Special detailing materials (sealants, screens, and stone particles) are used to block entry at slab penetrations and drainage points.
Below grade foundation walls, with their joints and (future) cracks, must also be protected by TERM® Water|Termite Barrier.
Above ground, TERM® Barriers protect sill and flashing areas against moisture and insects.
TERM® Barrier System, when properly constructed as part of the building envelope, acts as a barrier to almost all pests. Because almost all pests are excluded over the life of the structure, the need for pesticide treatments should be greatly reduced.
