FAQs

Are aluminium doors energy efficient?

Yes, modern aluminium doors are designed with polyamide thermal breaks, which include a specialist insulating barrier in the aluminium profile. This barrier reduces heat transfer through the metal frame, helping you maintain a comfortable indoor temperature.

Our Smart aluminium doors can achieve U-values as low as 1.5 W/m²K and are available with A-rated energy performance, meaning they deliver excellent thermal insulation while meeting UK building regulations. Combined with high-performance glazing and precision-engineered seals, they help reduce heat loss, meaning you could save on energy bills.
