Envirosheet

Overview

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.

Benefits

• 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.

Envirosheet is available in 2′ x 8′ and 4′ x 8′ sheets in compressive strengths of 12.5 psi, 22.4, psi and 37.3 psi, in both regular and shiplap joint.  Special orders can also be easily accomodated.

Applications
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.

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.
