Advanced ThermalHEART technology is the centre of each profile in the Vantage Residential and Metro Series ThermalHEART ranges. The result - maximum energy conservation and interior comfort.

A nylon thermal insulator separates the inside and outside metal faces in the ThermalHEART system. This cleverly integrated barrier stops the transmission of cold through the aluminium, and interior warmth is retained more effectively. This powerful enhancement combined with high performance double-glazing makes for the ultimate in year-round living.
