Do Dacatie cavity closers comply with Part L Building Regulations?

Part L Building Regulations state the minimum thermal resistance path (MTRP) through the cavity closer must be at least 0.45 m2K/W. Compliance with Part L Building Regulations is important. All Dacatie Cavity Closers well exceed this required value, as shown in the table below.

A product such as XFR2000 has a MTRP 3 times higher than in the minimum set out in Part L building regulations, click here to view XFR2000.
