At Insulspan, customer satisfaction is our highest measure of success.

"Part of the advantage of Insulspan products is that they magnify the efficiency of the home. Insulspan SIPs allow us to achieve the airtightness to make the home and the HVAC system work correctly.”

Richard Wayne, Insulspan Customer

We have received accolades from all over – including awards from the Building Systems Council of the National Association of Home Builders and recognition as the top ten green building product of 2007 by Sustainable Industries magazine – but the ones that mean the most come from our customers across North America. We took our first step toward ultimate customer satisfaction when we opened our doors 30 years ago, and since then Insulspan has led the industry in SIP technology – and in happy customers.
The Insulspan Structural Insulating Panel (SIP) System “sandwich” of performance-rated oriented strand board (OSB) structurally laminated to a continuous core of expanded polystyrene (EPS) insulation allows you to build and insulate your building in one step.

The Insulspan SIP System is an industry leading ready-to-assemble (RTA) system that gives builders a real competitive edge over traditional stick frame construction. The RTA process reduces construction time and improves efficiency. Blueprints for your home are loaded into our computerized factory equipment where Insulspan SIPs are manufactured to your exact specifications, then delivered to your location as a ready-to-assemble building system.

The energy efficiency of buildings built with the Insulspan SIP System out-performs buildings constructed using wood-framed wall and roof systems in three main areas:

• Insulspan SIP wall and roof assemblies contain less dimensional lumber. In wood-framed construction a thermal bridging is created between the exterior of the building and the finished interior when insulation is interrupted by wood studs which also leave more than 20% of the wall area uninsulated. Insulspan SIP wall and roof assemblies provide higher R-values than typical wood-framed construction alternates as there are significantly fewer thermal bridges.


• Higher R-value keeps conditioned air in. The R-value of a wall or roof is a measure of its ability to keep heat from flowing through it. Higher R-value for walls and roof means less heat loss and less energy needed for heating and cooling.


• The Insulspan closed cavity wall and roof design prevents air movement. In wood-framed construction, wall and roof R-value is decreased by insulation gaps around wood framing and by settling of insulation. These defects increase air leakage through the construction. This not only increases energy use, but can lead to condensation on the surfaces of wood components within assemblies. The continuous core of EPS insulation in an Insulspan SIP vastly reduces air leakage and heat loss, while also allowing better control of indoor air quality.
