Spray foam is often the go-to insulation for home and business owners who want to enhance the energy efficiency of their properties. Unlike traditional fiberglass insulation, foam insulation works its way into tiny spaces, where it expands. Regrettably, spray foam insulation can make conditions optimal for termites.
Termites love moisture. Because spray foam insulation retains moisture, termites may live inside it. Unfortunately, because spray foam insulation is not removable, pest control technicians often refuse to work in buildings where spray foam is present. Moisture barriers may provide the solution.
How do moisture barriers work?
In theory, if you can keep your spray foam insulation dry, termites are not likely to infiltrate it and damage your property. A moisture barrier, which may be rubber, polyvinyl chloride or similar material, installs inside a building’s walls. When you apply spray foam insulation, the moisture barrier provides a water-tight membrane that keeps it dry.
Do pest control companies work with moisture barriers?
If termites are inside your building’s spray foam insulation, you have a major problem on your hands. Often, technicians simply cannot eradicate embedded termites. While pest control companies have not widely agreed to address infestations in buildings with moisture barriers, the future is promising. That is, if moisture barriers become effective at keeping termites away, pest controllers may no longer refuse to provide services in buildings with spray foam insulation.
Ultimately, to be certain you do not void your building’s warranty, it is critical to inquire whether applying moisture barriers and spray foam insulation is acceptable.
