Thermal Efficiency

Energy Rating Certificates

An energy-efficient home is a major concern for many modern homeowners. 

New energy regulations for doors mean all door manufacturers and resellers will have to prove compliance. A generic certificate for certain door ‘types’ is unlikely to suffice.

Using a calculation method verified by the Building Research Establishment and BFRC door-stop’s energy rated doors come with a unique energy rating certificate, delivered immediately at the point of order.

This is not a type test or a dubious assurance that gives all doors the same U-value. It is tailored for each particular door configuration.

 

 

Energy efficient doors

All of our trade composite doors exceed the current Building Regulations for energy efficiency, which came into force in October 2010, covering front doors for the first time. Under the legislation, all new doors sold and fitted in England and Wales must have a U-value of 1.8W/m2K (1.6W/m2K in Scotland) or less. The door’s U-value is a measure of its energy efficiency, and the lower the U-value, the more energy efficient the door.

Choosing thermal glass on the doors makes them even more energy efficient, with an ultimate U-value of just 1 W/m2K.

Many manufacturers of doors made of timber, aluminium or PVC panels may struggle to meet the 1.8W/m2K requirement and many do not provide proof, although there are likely to be further energy efficiency revisions in upcoming legislation.
