Part L – How does this affect PrimeFOLD?

Part L


Thermal regulations for doors are changing to meet Goverment carbon emissions target from the 15th June.
This means all doors for new and existing buildings will be upgraded to match the new U-value energy ratings to make them more thermally efficient!


What are the new Part L regulations?

For Doors that are over 60% glazed and being installed into new or existing properties, the maxiumum U-value will be 1.4 W/(m2k) or Door Energy Rating (DER) C.
For all other doors in new or existing properties the maximum U-value will become 1.4 W/(m2k) or DER B.


Does PrimeFOLD comply?


Our PrimeFOLD bifolding doors is DER rated C for existing properties & meets the new build requirement of 1.6 W/(m2k)
