SAP Calculation Service

SAP Calculation ServicesLet Knauf Insulation help calculate your planned energy usage - we may even be able to help recommend ways to reduce your carbon emissions!

Knauf Insulation's accredited SAP assessors are able to help specifiers and developers to ensure compliance with new Building Regulations.

Where a specification does not meet regulatory requirements, our experts are able to provide assistance and recommendations to help reduce carbon emissions and achieve compliance.
