TERM® Barrier for Isolation Joints

I have written extensively in past TERM blogs about termites and the damage they can do to structures. But why? Besides the fact that I am an entomologist, and bugs are just plain cool, I am part of a team at Polyguard that has worked for many years to bridge the building industry and the pest management industry.


Architects and Entomologists

Current building standards require the use of materials that keep air and moisture out of structures. Recent improvements on these building materials and their installation have made it possible to add termite and pest exclusion to the building envelope as well.

TERM® Membrane Barrier protects against termites

Subterranean termites cause an estimated $5 billion in damage to structures in the United States each year (source). Since termiticide pretreatments are not required in all states, that cost has the potential to increase.

Termite Tubes Termite Damage

Polyguard has manufactured building envelope materials for sealing out water, and for sealing in energy, since 1970. In the TERM Barrier System Division, we have upgraded these same building envelope materials to exclude pests, as well.

By not including pesticides in our products, but instead strengthening them and installing them in the structure, we have created a physical barrier. Physical barriers do not kill pests, like a pesticide or a trap would, but instead physically block pests from movement into a structure. Physical barriers are not a new concept, but recent advances in the use of building materials to effectively exclude pests have made it possible to add new dimensions to integrated pest management strategies.

Non-Pesticide Termite Barrier

Implementation of non-pesticide termite and pest barriers into the building envelope can put long-term pest control options into the hands of the architect, builder, and subsequent owner.

Apply TERM® Sealant Barrier

Think of Polyguard as an innovator and manufacturer of barriers – not just barriers against moisture and corrosion, but against contaminants like radioactive radon gas, methane, and insect pests. The solution to all of these building envelope offenders lies in the TERM Barrier System.
