What are the Building Regulations for the Thermal Performance of Front Doors?

If you are planning or are mid-way through a renovation or new build project, you will need to consider a new front door. Throughout your project, you will be contending with Building Regulations, and the decision on a new front door is no different.

Building regulations applies to front doors, and one of the most challenging regulations is part L which details ‘The Conservation of Fuel and Power in Buildings’. What does this have to do with a new front door?

Let’s investigate what Part L of Building Regulations means and why it affects your choice of front door.

What is Part L of Building Regulations?

Part L of building regulations relates to construction projects involving new builds, renovations, or a change of use to a building or dwelling for properties based in England. It states the standard for energy performance and carbon emissions of new and pre-existing properties.

Energy requirements are advancing and becoming increasingly strict with a heightened focus on environmental issues and our carbon footprints. The UK government has pledged to significantly reduce carbon emissions by 2050, and all home improvements must meet these building regulations for thermal performance.

All new external doors must meet the required minimum level of heat loss measured by a U-value as stated in Document L of building regulations.

How do I know if my new front door complies with Part L?

The critical point of understanding your new front door’s thermal efficiency is to note its U-value. Different doors require a different U-value to pass the Part L building regulations, depending on the glazing used. We have taken the time to find this out, so you never have to worry.

• Part-glazed doors need U-values from 1.2W/m2k
• Fully glazed doors need a U-value from 1.4 W/m2k
• Solid doors with no glazing need a U-value from 1.0W/m2k
