BM TRADA is an approved as an Independent Agency for the British Fenestration Rating Council and provides ratings for the door energy ratings scheme.
The door energy rating scheme provides a method for manufacturers to demonstrate the energy performance of their doors.
The current Building Regulations in England and Wales require replacement doors to have a U-Value of 1.8W/m2K or less, however future versions are likely to contain an option for compliance through door energy ratings.
The door energy rating scheme provides a method for manufacturers to demonstrate the energy performance of their doors, taking into account heat losses through thermal transmittance (U-Value), air leakage and, for certain types of door, heat gained from the sun (G-Value or solar gain) and gives an A to G rating in a similar way to the existing window energy ratings.
Most styles of doors are included in the scheme, and different types of door construction are covered with various options available for glazing.
