Korolite® Expanded Polystyrene insulation (EPS) is a high-performance, closed cell, rigid foam insulation material that uses air as main ingredient. EPS insulation resists moisture and mold/fungi growth with low environmental impacts, high Long-Term Thermal Resistance, and good drying potential over the long service lives of buildings.

Adding continuous insulation (c.i.) offers higher effective insulation values than adding similar amounts of cavity-insulation and it greatly reduces the risk of condensation, rot and mold on framing members with proper detailing & installation. All Korolite® types are available in various standard and customized sizes & thicknesses and can be factory-tapered.
