What Makes a Door Energy Efficient
Insulation, sealing, and smart design
Energy efficiency depends on how a door is built and installed. Modern designs include insulating cores, thermal breaks, and weather seals that reduce heat loss and prevent draughts. The materials used also play a big part. Aluminium, composite, timber, and uPVC doors all provide excellent performance when designed correctly.
At Sussex Doors, we only supply products that meet or exceed energy performance standards. Every door is made to keep warmth in during winter and reduce heat build-up in summer.
Composite Doors
Composite doors are known for their excellent insulation. The solid core and multi-layer construction make them one of the most energy efficient options for any home.
Aluminium Doors
Modern aluminium doors use advanced thermal breaks that prevent heat from escaping through the frame. They combine strong insulation with a sleek, durable design.
Timber and uPVC Doors
Timber doors offer natural insulation, while uPVC designs provide a practical, low-maintenance way to improve energy performance in both traditional and modern homes.

Weather resistance is just as important as insulation. A well-fitted energy efficient door helps prevent draughts and moisture from entering, keeping your home comfortable and well protected in all conditions.
Small Change, Big Impact
Replacing old or poorly insulated doors can significantly improve your home’s energy rating. You will notice fewer draughts, more consistent indoor temperatures, and lower energy bills.
Choosing energy efficient doors also supports a more sustainable way of living. Sussex Doors can help you find a design that complements your home and performs to the highest standards.
