The structural insulated panel (SIP) is one of McDonough's favorite products. Composed of foam insulation sandwiched between two sheets of oriented strand board, SIPs create a tight home and save lumber. Winter Panel offers a range of products in 4½-inch and 6½-inch thicknesses. Winter Panel Home Construction, 802.254.3435; www.winterpanel.com.
