Construction Details for Kingspan Insulation
Thermal bridges can account for a significant amount of heat loss from a building. Our standard construction detail guides provide clear process sequences and calculated psi-values when installing our products at major junctions.
Download our construction details and indicative psi-values
Achieving low psi-values at building junctions can help to raise building energy performance and support compliance with the Building Regulations and Standards. Our standard construction details provide psi-value calculations for the use of different Kingspan Insulation products at major junctions. Each detail has been carefully created to ensure a workable process sequence for site workers whilst also improving on the default psi-values provided in table K1 of SAP and the NCM.
