Insulation helps keep people comfortable. Unfortunately, insulations are susceptible to termite infestation. Termites love to live, work and eat in comfortable and protected surroundings. All insulation can potentially provide this environment. R-Control Perform Guard EPS is a termite resistant expanded polystyrene insulation for all types of R-Control construction. It is used in Structural Insulated Panels (SIPs), Insulated Concrete Forms (ICFs), Perimeter and Under-slab Foundation insulation, EPS Geofoam, and other R-Control Building Systems.
