Thermapan SIPs always result in vertical straight walls. They're easy to install and it's easy to hang drywall. They have excellent sound insulation and make for sturdy, solid walls.

The energy savings are substantial. On a recent project, the original home was approximately 1,000 sq ft and cost $1,400 in 2002 to heat. Its replacement, a new SIP-built home, was 4,100 sq ft, yet heating only cost $1,400 in 2004.

This was the first time we've built with Thermapan SIPs, and I would definitely use them in the future.
