What is a SIP?
It's the better way to build!

A Structural Insulated Panel (SIP) is a panel composed of expanded polystyrene insulation (EPS) board laminated between two sheets of oriented strand board (OSB).

With a proven history of performance since 1952, SIPs are a proven - and preferable - alternative to conventional "stick and batt" framing systems.

Thermapan SIPs are perfect for many different applications, such as walls, roofs, floors, foundations, timberframe, log homes, additions, and renovations.

The benefits of SIPs are numerous:

• Energy efficiency
• Healthy home - prevents "Sick House Syndrome"
• Living comfort
• Structural performance
• Environmentally friendly
