Envirosheet is a high performance flat sheet rigid foam insulation made from Expanded Polystyrene (EPS).
Envirosheet provides the best value and economy because it provides the highest r-value per dollar of all generic rigid insulation types on the market.
- Creates thermal envelope for maximum heat/cooling efficiency
- Moisture resistant for lasting performance
- Provides level surface for finishings
- Lightweight, easy to handle
- Recyclable, contains no CFCs or HCFCs
Size & Density
To meet your unique construction needs, we offer a broad range of products, both conventional and innovative, for every kind of building insulation application.
ES-12 Envirosheet Expanded Polystyrene (EPS) foam board applied over exterior walls eliminates thermal bridging, reduces air infiltration and provides a higher r-value. Various finishes including, stucco, siding, brick veneer and all other traditional exterior finishes can easily be used in combination with Amvic EPS insulation.
ES-22 and ES-37 Envirosheet Expanded Polystyrene (EPS) foam board can be applied directly over damp proofing or waterproofing systems and anchored (various/optional) into the concrete/block walls. Amvic EPS foam board remaining above grade must be UV protected with parging coats to prevent damage.

Surface Burning Characteristics of Envirosheet® in accordance with CAN/ULC-S102.2
|Material Details||Classification or Rating|
Expanded Polystyrene (EPS) is a combustible material. When tested in accordance with CAN/ULC S102.2, combustible material of greater density or increased thickness will increase fuel loading and hence increase the measured flame spread ratings.
