Why use rigid insulation?
First, of course, is energy efficiency that has been the prime motivation behind SIPS development. Sips Industries Panels provide higher U-values, reduced air infiltration, less thermal bridging and greater stability all within conventional wall and roof thickness. The rigid insulation cannot sag, slump or shift and is a constant throughout the building. The U-value remains very stable over time and is minimally affected by moisture. There are far fewer interruptions in the insulations Sips Industries Panels span widths of 1200mm, while the insulation in stick construction are interrupted by studs every 600mm Sips Industries Panel buildings greatly reduce air infiltration and thermal bridging. The energy efficiency of and Sips Industries Panel structure means reduced heating and cooling loads, which in turn can mean savings in running costs.
