Energy Ratings and Thermal Efficiency

With modern doors you can guarantee that thermal performance sits highly in the performance table when pitted against other materials.

Thermal performance along with security and durability were high on the agenda, during the design process of our doors. With excellent thermal insulation provided by the multi-chamber system, weathertight seals and gaskets ensure that A+ energy ratings can be achieved with ease.
