How much are they? Do Sips walls cost more than frame walls?
When evaluating the cost of building with a Sip you need to look at the overall construction costs and long-term operating costs, not just the cost of the material. Sips result in less waste, less field labour requirements (along with the associated field labour overhead costs, such as transportation, lodging, meals, benefits, etc.), much faster construction time (and fewer weather delays), lower HVAC equipment costs, and greater comfort. Long-term operating costs for utilities are greatly reduced. Sips are even more competitive when the design is optimized to incorporate them. Consequently, architects design dimensions at 1m and 1.2m increments, engineer roof pitches at steeper angles to increase loft square meterage, and make other similar adjustments to take full advantage of SIP capabilities. Sips, therefore, usually result in lower overall building costs and better value.
