If you are going to buy a new front door, make sure you buy a well-insulated door that keeps the heat in and shuts out the cold.
All our doors are sealed and well insulated as standard.
If you want an even more energy-efficient door, we have the Low Energy option. Then the door will be thicker with more insulation and if it is glass, energy glass. With the Low energy option, you get down to a U-value of 0.65.
