Once installed, SIP panels deliver unrivalled insulation and airtightness, which reduces energy costs over the building’s lifetime. SIPs are known to be about 50% more energy-efficient than traditional timber framing. A SIP building envelope has minimal thermal bridging and delivers excellent airtightness, which lends itself ideally to LEED and net-zero-ready building standards.
A SIP home or commercial building allows better control over indoor air quality because the airtight building envelope limits incoming air to controlled ventilation, which filters out contaminants and allergens. The SIP envelope doesn't have the voids or thermal bridging of conventional stick framing that can cause condensation leading to potentially hazardous mould, mildew or rot.
SIPs are highly energy-efficient and therefore contribute positively to the environment by reducing CO2 levels. They also use significantly less energy during the manufacturing process compared to traditional construction methods and have lower embodied energy than traditional construction materials, such as steel, concrete and masonry.
