How to choose an energy efficient front door
Advice on the features to look for when selecting a front door that won't let any warmth escape.
Whether you are renovating the entrance to your home or building a new one from scratch, the importance of a good front door is not just about its looks. Matt Higgs, director at Klöeber explains the key factors to consider when choosing a new energy efficient front door.
The rate at which heat is transferred through a material or product is known as the U-value. The lower the value, the better. Look for a front door with a U-value of less than 1.8W/m2. The most energy efficient front door has insulation at its core. Some timber and composite doors have a high-performance insulating core, while others just have a void.

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