Matt Risinger visits a large home under construction in Vancouver British Columbia and explores the high-performance house's construction details with the owner/builder. The house features Euro-style windows from a Canadian manufacturer called Innotech, and in this video Risinger tours the factory where they are made, with frames fabricated from rigid unplasticized polyvinyl chloride (uPVC). Afterwards, the owner explains how he put together the home's thick foam shell and integrated the tapes and various air and water control layers to achieve low heating and cooling bills for the 5,000 square foot house.
