Ever since stick framing was developed decades ago, most homes in the U.S. have been built with that method. But now more builders are switching to advanced building envelope technologies such as structural insulated panels (SIPs). Compared to stick framing, SIPs are substantially more airtight, offer higher-performance insulation, speed up construction, and provide builders a ready way to address shortages of skilled framers.
From California’s Title 24 Building Energy Efficiency Standards to the 2012 International Energy Conservation Code (IECC), SIPs help builders meet the most demanding energy requirements and ensure a better insulated, more airtight envelope.
Title 24 is arguably one of the most stringent energy codes in the U.S. and requires that, “all joints, penetrations, and other openings in the building envelope that are potential sources of air leakage shall be caulked, gasketed, weather-stripped, or otherwise sealed to limit infiltration and exfiltration” (section 110.7).
