How A Composite Door Can Impact Your Thermal Efficiency

Did you know About 35% of heat loss occurs through walls and through gaps, in and around windows and doors?  Therefore a poorly insulating door could be responsible for a high quantity of this figure. When you feel the cold getting through your door you could always try a quick fix and install draught proofing around the door to stop cold air rushing through. However it is worth noting that composite doors have been designed to permanently fix this problem.

The backstory of the composite door

It is very fitting that a composite door consists of various materials including UPVC and wood as it was partly introduced to the market in the 1990’s to give people an alternative to traditional timber doors and UPVC door designs.

Coated in a GRP (Glass Reinforced Plastic) skin, it has a hugely dense internal core. This gives it unrivalled strength and impressive thermal insulating qualities.

Top thermal performance

Current building regulations require replacement doors to achieve a U-value of 1.8 W/m² or less. A U-value indicates how much heat passes through a door – the lower the U-value, the more energy efficient it is. Composite doors carry a very low U-value and exceed the necessary thermal standard.

When integrated into your entranceway, a good composite door will keep the weather where it should be – on the outside. The end result? A warmer and securer home of course and much more affordable energy costs.
