SAP Rating & Energy Performance of SIPs
for House Builders
​
Why SIPs Panels Deliver Exceptional SAP Ratings
Structural Insulated Panels (SIPs) are among the most energy-efficient construction systems available.Their high thermal performance and airtightness contribute significantly to better SAP scores, helpinghomes meet or exceed Part L regulations and EPC Band A or B.
Thermal Performance & U-ValuesTypical U-values for SIP panels based on thickness:​
Airtightness & SAP ImprovementSIPs offer superior airtightness due to precision manufacturing, often achieving values as low as 1 m3/h·m2@50Pa. This dramatically lowers energy demand and helps achieve high SAP scores without relyingheavily on renewables.
Reduced Thermal Bridging
SIPs significantly reduce thermal bridging thanks to their continuous insulation.
