When choosing a new front door, it's a good idea to check its energy efficiency credentials.

The finishing touches of your self build are just as important as the bigger decisions of your build journey. We spoke to Matt Higgs, director at Klöeber on the key factors to consider when choosing a new front door that is energy efficient. 

Planning and permissions

With new-builds and major renovation projects, the front door will form part of the planning application for the entire scheme. If you’re upgrading your home, a like-for-like replacement falls under permitted development rights (PD) and you won’t need planning consent, unless the property is listed or in a conservation area, or if you’re creating a new opening or widening the existing one.

Make sure you’re clear on the rules in your area by checking with your local authority before beginning any work. Fitting a front door is subject to building regulations. Choose your door supplier’s installation service or hire a reputable joiner who is familiar with building regulation requirements.

Heat retaining

The U-value is a measure of the heat lost through the product. It should be lower than 1.8W/m2. The best thermal efficiency comes from a door with insulation at its core. Some timber and composite doors have a high-performance insulating core while others have a void. 

Air resistant

L-value is a measure of air permeability, which is measured in pascals – a higher pascal rating is better. To protect against air leaks, chose a material that won’t move, swell or bow with changes in the weather. It‘s also important that the doorframe is insulated and sealed to stop air and water coming through.

Solar energy

The G-value is the percentage of solar energy that passes through glazing; a lower rating is better. If you’re incorporating glass panels, then consider the solar gain factor. For south-facing elevations, solar control glass that reduces heat gain will be a good option.
