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.

Safety glass should be fitted in all doors and other windows or glazed areas that are lower than 800mm from the floor level as indicated below
The first rule of thumb is to make sure you take accurate measurements in millimetres not inches. This gives you a finer level of accuracy and means there’s no room for error if we have to convert the measurement to metric.
So firstly step outside. You need to take height and width measurements for the brickwork opening. Bear in mind that the height measurements must be from underneath any existing removable windowsill. If your property is rendered, simply take off a little of the render and measure to the brickwork edge.
Remember the opening may not be exactly square so take a minimum of three measurements – top, middle and bottom, for the height and the same again for the width. This means your window manufacturer can get an accurate view of the exact size of the space the finished product will be fitted into. The final width and height measurement the manufacturer will use is the smallest one.
This sounds like odd advice but you need to take off 10mm from the final height and width measurements. This is to allow for a small fitting allowance around the new frame and means the fitter can make sure the new window frame sits squarely when it’s in place. Any gaps are then fitted with spacers and filled to keep the frame in just the right position.
This is a common error and certainly one to avoid. Ignore the old window frame – this is going because it is no longer suitable. Consider the fact that it may well have warped so the last thing you want to do is take measurements from it!
Make sure you check (and double-check) your measurements so you are 100% sure you have them correctly. This is important because we will not accept responsibility for incorrect measurements and you will still have to pay for a window that doesn’t fit. If you are unsure, consult a professional installer or builder and give yourself total peace of mind.
Taking all the above information in to account, when inputting your measurements we require you to provide us your overall brick-to-brick measurement minus the 10mm fitting tolerance. We will automatically include the cill in to the measurements you provide us – pending you require one that is!
If you struggle, or you would like us to contact you for piece of mind, once your order is placed just leave a note at the checkout asking for a call back!
