PermaTherm Expanded Polystyrene (EPS) Foam Panel Insulation
Our expanded polystyrene (EPS) foam panel insulation is the “core” of each highly-efficient PermaTherm insulated panel system. More than simply a form of insulation, it is also an innovative building material that lends to the design and structural integrity of many building projects.
And PermaTherm’s rigid foam panel insulation is “not your typical EPS.” Since the 1950’s, PermaTherm EPS has been recognized as a superior, mainstream insulation material, and new applications with PermaTherm EPS have greatly increased in number over the last decade.
PermaTherm EPS foam panel insulation is ideal for most insulation specifications and is easily fabricated to meet specific design and dimensional requirements. Contact our team atto learn more about our rigid foam insulation for panels, or check out the resources below:
Benefits of PermaTherm EPS Rigid Foam Panel InsulationPermaTherm manufactures its EPS rigid foam panel insulation under strict proprietary protocols. Quality control is assured through our state-of-the-art expanding, molding and curing facility. The end result is an absolutely superior insulating core, with the following benefits:
- Our EPS foam insulation for panels has excellent thermal resistance and long-lasting thermal conductivity values.
- It’s lightweight, easily-shipped, stored, handled and installed on the job site.
- PermaTherm uses only UL-approved raw materials – there are no exotic blowing agents or volatile chemicals that may react negatively with other materials.
- Due to its design flexibility and versatility, it can be cut into sheets, slabs or any design requirement to meet specific building code standards.
