The TERM Barrier Systems Division of Polyguard specializes in developing sustainable pest barriers, without the use of pestic ... ides. TERM means Termites, Energy, Radon, and Moisture prevention in one building envelope solution. While good engineering can minimize building movement, structures are not engineered to eliminate minuscule openings created by construction and nature. Consider that the building envelope can be upgraded to seal off almost all pest entry points and accommodate for the small movements of building components. Since 1953, Polyguard has manufactured building envelope materials for sealing out water and containing energy. Working with pest management professionals and entomologists since 2000, TERM's mission is to enhance the integrity of buildings with a sustainable, purpose-built insect exclusion barrier. https://www.youtube.com/watch?v=9Pk2tKewfo8 read more
