Your Source for Award-Winning Open Wall SIPS and Building Kits

Insul Wall is a patented Canadian building technology developed by TrueFoam. It combines insulation and framing in a unique system that unites conventional wood framing with highly efficient rigid insulation and also eliminates the need for exterior sheathing. It offers outstanding energy conserving properties, and saves trees by using structural wood very efficiently.

The core of the system is TrueFoam expanded polystyrene (EPS), an exceptionally versatile insulating material. Used in construction since 1951, EPS is well known for its durability, thermal stability, and safety.

Since EPS is breathable, it allows water vapour to pass through, eliminating condensation and the related threats of rot, mould and mildew. However, because TrueFoam EPS is composed of a solid structure of closed cells, it does not permit the kind of air movement that causes convection heat losses so typical of homes built using fibrous insulations.

Insul Wall takes maximum advantage of the structural integrity and insulating ability of EPS. Standard wood framing members, contained in slots within the EPS panels, are separated from the exterior surface of the wall. This prevents thermal bridging within our insulating wall panel, where heat escapes through framing – often a major cause of heat loss in traditional construction. Exterior finish siding is attached to 1″ x 3″ strapping incorporated in the outer face of the Insul Wall panel.

The unique design of Insul Wall permits standard 2″ x 4″ studs to be used to meet R-value requirements that would demand 2″ x 6″ framing in other systems.

Insul Wall isn’t just about walls, either. The system includes high R-value ceiling components as well. Insul Wall meets and surpasses all national building code requirements, and is used as an approved and accepted method under the R-2000 program.

Insul Wall is available in pre-assembled wall sections custom made to suit your house plans, reducing on-site labour to a minimum. If you prefer, it can also be provided in the form of easy-to-assemble components, which are available to you in SIP kits. Our SIP kits can dramatically reduce building time, and your overall building efficiency.

Insul Wall is part of an integrated system of TrueFoam insulation products designed for cost effectiveness, durability and versatility. TrueFoam insulation products can substantially reduce heating costs while protecting the integrity and long-tem comfort of your home.
