Thermapan Structural Insulated Panels

Foundation Panels

Overview

Foundation SIPs are specifically engineered for below grade uses. The PWF (Permanent Wood Foundation) exterior sheathing resists wood decay.

SIP foundations have numerous advantages over traditional concrete foundations:

  • Dry basements with no mustiness
  • No framing required to insulate and finish basement
  • No cracking
  • Fast construction – no concrete to cure
