Since October 2010 all new doors will have to meet a door U Value rating of 1.8W/m2K or less. Each and every door AWM Windows and Doors supplies is U value compliant. We do however always give you the option to superceed the standard requirements by upgrading your glass to Thermal Spacer Bars – A Rated Glass giving a U-Value of 1.4W/m²K
AWM Windows and Doors are dedicated to not only making sure our doors and windows are fully U value compliant, but also our customers understand as much as they can about the regulations. We have created this U Value section to remove confusion and promote informed decision making.
The following information summarised from Building Regulations Documents L1A (New Dwellings) 2010 & L1B (Existing Dwellings) 2010.
|FITTING||(A) STANDARD FOR NEW FITTINGS IN NEW DWELLINGS||(B) STANDARD FOR REPLACEMENT FITTINGS IN AN EXISTING DWELLING|
|Window, roof window and roof light||U-Value = 2.0W/m²K||U-Value = 1.6W/m²K or Window Energy Rating = Band C|
|Doors with more than 50% of their internal face area glazed||1.8W/m²K||1.8W/m²K (or exempt if fitted into existing door frame)|
|Other doors||1.8W/m²K||1.8W/m²K (or exempt if fitted into existing door frame)|
In the coming year the regulations are due to change once again. From July 1st 2022 the UK are looking to reduce the carbon footprint by up to 30%.
The latest revisions to building regulations mean energy efficient doors will be made mandatory. As an imminent introduction of the U value for doors means all new doors will need to have a value of 1.8W/m2K or less (the current standard for energy efficient windows). We think this is a good step as there’s not much point in insulating your roof and walls and having ‘A’ rated windows if your door isn’t energy efficient too – heat will find the least insulated point and escape through it.
When the new regulations are applied, we will update this page accordingly.
