About ThermalHEART technology

Advanced ThermalHEART technology lies at the centre of each profile in the ALTHERM Residential and METRO SERIES ThermalHEART ranges. The result - maximum energy conservation and interior comfort. A thermal insulator has been cleverly included into each window and door to ensure that cold transfer is minimised and interior warmth is retained. This powerful enhancement combined with high performance double glazing makes for the ultimate in sensible year-round living.
