The thermal and mechanical properties of expandable polystyrene (EPS) make it ideal for applications where R-value and moisture resistance are critical. Expanded Polystyrene (EPS) insulated siding marries an exterior siding panel (skin), whether metal, vinyl, composite, or other cladding material, with a shaped foam backer (core) precisely contoured to fit the siding profile at all points of contact.

Performance Benefits with Expanded Polystyrene (EPS) Foam
When siding with Expanded Polystyrene (EPS) is applied to the exterior wall it helps to create an envelope around the structure covering all the wall cavities and studs to increase resistance to heat transfer either out of or into the building. Without a continuous insulation barrier, energy transfer through the studs (referred to as thermal bridging) is more prevalent especially in wood and metal frame construction. Insulated siding prevents thermal bridging and enhances the overall system R-value. 

The backing increases the siding’s R-value by as much as five times that of regular vinyl helping to reduce annual heating and cooling energy costs by up to 20%. Trimtec Systems can achieve varying R-values depending on density and thickness to provide the exact level of insulation required. This makes insulated vinyl siding a great way to improve on any construction method that only insulates in between wall studs.

Expanded Polystyrene (EPS) is an ideal choice because it does not rot, is resistant to mold and mildew—and is proven to be a safe, highly effective compound with excellent thermal properties and added sturdiness when used as a part of a hybrid insulating system. And, it is highly compatible with a variety of traditional building materials, such as metal, wood, masonry and other plastics. Insulated vinyl siding is not as brittle in
the winter and won’t buckle in the summer, it won’t dent or cup, which improves the home’s appearance and prevents callbacks.

Impact Resistance
The most important mechanical property of Expanded Polystyrene (EPS)in insulation and building products is compressive resistance – its ability to resist compressive stresses. This ability increases as Expanded Polystyrene (EPS) density becomes higher. Tests performed by an independent laboratory concluded that siding panels insulated with Expanded Polystyrene (EPS) foam absorbed impacts from 160 PSI to 340 PSI, depending upon the siding material. It is conservative to conclude that the rigid Expanded Polystyrene (EPS) foam structural support used in today’s premium engineered siding products increases the impact resistance of ordinary vinyl siding by more than 400%.
