According to the U.S. Department of Energy, heating and cooling account for about half the energy use in an average home. For most of us, it's easily our largest energy expense.
Much of that energy is wasted, and the culprit is the way our homes and buildings are constructed. Traditional building and insulating methods allow cold and warm air to move through walls and roofs, and escape or infiltrate through gaps.
Even the wood in studs and rafters themselves causes energy loss. Through a process called thermal bridging, the wood frame of a building conducts heat, from the inside out during winter, and from the outside in during the summer months.
SIPs solve air infiltration and leakage problems by eliminating the cavities in walls and roofs. Air simply cannot move through the solid EPS core that's adhered tight to the OSB in a SIP.
And, because they contain no studs, SIPs conduct little heat. The result is a continuous insulation and air barrier that drastically reduces energy loss. SIPs can reduce energy consumption for heating and cooling by 50 to 70% compared with conventional wood framing.
