Rigid polyurethane foam is approximately twice as efficient as mineral wool quilt
SIPS offer exceptional thermal performance with U values of 0.10 (252mm thick) to 0.28 (100mm thick)
Less energy is required to heat the building resulting in a reduced fossil fuel requirement and a corresponding reduction of up to 60% in carbon dioxide emissions
The air tight structure of Thru-Wall is achieved with less than one air change per hour
Thermal bridging is minimised compared to conventional constructions
