Structural insulated panels (SIPs) provide sustainable buildings with high thermal performance and airtightness with applications for a wide range of education, residential, leisure, commercial and healthcare projects.
SIPs are prefabricated, high performance, lightweight building components used in external walls and roofs. The panels are made by sandwiching two layers of orientated strand board (OSB) structurally adhered to a core of Expanded Polystyrene (EPS). SIP walls can bear considerable vertical and horizontal loads with reduced internal studding. The load carried by the SIP is transferred to ground by the OSB skins, held in position by the insulation core.
It’s a system that is extremely strong, energy efficient and cost effective to use. Not to mention quick to assemble on site.
Challenging Building Regulations and Government strategy for low and zero carbon building means higher standards for insulation and airtightness are guaranteed. Fabric energy efficiency standards is now an essential part of the equation, demanding much more of the industry and driving the market for SIP building systems.
It’s simple. Highly insulated buildings keep heat in. Low carbon construction – throughout the building envelope – needs insulation, airtightness and junction performance, as well as the balancing required from building services and ventilation. The Fabric First approach enabled SIPs puts sustainability and energy efficiency into the heart of the design. We can build for any desired thermal performance, achieving U-values as low as 0.10W/m²•K.
