Our thermal rated doorsets have been developed to meet the increased demands for energy-efficient buildings as part of a greener future.
Thermaguard* Technology includes a range of design innovations that reduce the U-value of a typical doorset to 1.4 W/m²K, meeting the latest requirements of the Building Regulations Part L in England and Wales.
These include a unique perforated frame design (UK Patent pending), insulated frame and increased leaf thickness. The design calculation has been provided by an accredited UKAS approved company using the simulation method as defined by the requirements of BS EN 10077-2:2017.
