Door Energy Ratings – DER’s
Building Regulations received a massive overhaul in October 2010 and all windows and doors had to comply to minimum U value standards. Windows 1.6W/(m2.K) and 1.8W/(m2.K) for doors. On 1st September 2011, the DER scheme was officially launched.
All of our front and back doors exceed the minimum 1.8W/(m2.K) required.
In fact our doors range from just 0.8W/(m2.K) A rated doors to 1.5 W/(m2.K) for our C rated door.
All PracticalDoorShop Doors ordered come complete with an energy rating. This gives our customers peace-of-mind that the door will function to the high level we state on our website, since the rating comes from an independent certifier. Each door will have a different energy rating, depending on the options chosen.
Composite doors are by far the most superior doors on the market when it comes to energy efficiency, up to 10x that of timber doors! Although some uPVC doors can have similar U values to composite doors, unlike uPVC doors, our doors remain stable during heat changes, preventing cold spots from appearing and giving you lasting energy efficiency and save money on your heating bills.
