We’re sure you don’t need reminding of the rising energy costs currently in the United Kingdom. Increasing bills are making thermal efficiency a more important consideration for homeowners when making home improvements.
While windows often receive the most attention, an ageing or poorly performing front door can also contribute to heat loss and reduced energy efficiency within the home.
Modern composite doors are designed to provide much higher levels of thermal performance than many older entrance doors. They help create a warmer and more comfortable home by reducing unnecessary heat loss throughout the year.
Endurance doors are a premium solution, combining thermal efficiency, security, durability and bespoke design.
Heat Loss Through Doors
Put in simple terms, poorly insulated doors allow more warm air to escape. This makes a thermally efficient front door an important part of creating a comfortable, energy-efficient home.
U-value is a measurement of how effectively a door prevents heat transfer. The lower the U-value, the better the thermal performance. All Endurance composite doors achieve U-values of 1.4 W/(m²·K) or lower, meeting current Building Regulations.
Different aspects of an Endurance door, including a 48mm solid timber core, reinforced frame, an airtight compression system, and high-performance glazing, combine to create a high-performing doorset designed to help reduce heat loss and improve your home’s overall energy efficiency.
Winter & Summer Performance
Thermal efficiency benefits your home year-round, not just during the colder months. In the winter, a thermally efficient door helps retain warm air and reduce draughts, creating a more comfortable entrance.
Alternatively, in the summer, insulated construction helps reduce unwanted heat transfer, contributing to a more stable and comfortable indoor temperature throughout the year.
The CoolSkin heat-reflective technology featured on Endurance doors reflects heat energy and helps to reduce the door’s surface temperature. Homeowners can also choose to upgrade from standard double-glazing to triple-glazing for enhanced performance.
Savings on Energy Bills
By helping reduce heat loss, a thermally efficient front door can contribute to a home that requires less energy to maintain a comfortable indoor temperature.
Improving the thermal performance of the entrance can contribute to overall household energy efficiency, with less reliance on energy use. Thermal efficiency should be viewed alongside security, weather resistance and durability when assessing long-term value.
For this reason, a premium composite door should be seen as an investment in everyday comfort as well as the long-term performance of your home.
Thermal Performance Comparison
| Door Feature | Thermal Benefit | Endurance Specification |
|---|---|---|
| 48mm Solid Timber Core | Helps reduce heat transfer through the door | 48mm solid timber core with 17-layer cross-laminated construction |
| Low U-Value | Helps keep warm air inside the home | U-values of 1.4 W/(m²·K) or lower |
| Airtight Compression | Reduces draughts around the doorset | External gasket and adjustable hinges provide a tight seal |
| High-Performance Glazing | Improves insulation while allowing natural light | 4mm soft-coat glass with 90% argon gas fill; triple glazing available |
| CoolSkin Technology | Helps regulate surface temperature during warmer weather | Heat-reflective uPVC skins |
