Why SIPs?: "Our clients were seeking a net zero home - one that would produce at least as much energy as it would consume. SIPs were the logical choice for creating the highly insulated, air-tight envelope needed to achieve net zero in the Pacific Northwest. SIPs always make for a more efficient build, in terms of saving time on labor during construction and saving energy for the client, once the home is ready to occupy."
