Air Tightness Testing Rochdale From £250

What is air tightness testing in Rochdale?

Air tightness testing — also called air permeability testing — measures uncontrolled air leakage through the envelope of a new dwelling. A blower door fan pressurises the building and the leakage rate is calculated in m³/(h·m²) at 50Pa. The result is mandatory under Part L of the Building Regulations and feeds directly into the SAP calculation. Rochdale has seen significant new-build activity, particularly across modern estates in Norden and Bamford, so our UKAS-traceable testers cover Rochdale sites with rapid mobilisation.
