ThermalHeart technology in Altherm Residential and Metro series


For designers, builders and homeowners seeking temperature comfort in homes, especially during winter, we offer advanced ThermalHeart technology in Altherm Residential and Metro series windows and doors.

Windows and doors featuring ThermalHeart technology have nylon thermal insulators separating the inside and outside metal faces. This cleverly integrated barrier stops the transmission of cold through the aluminium.

ThermalHeart is a smart and affordable investment with substantial long term energy savings and health benefits. It is always used with double-glazing, and a variety of high performance thermal glass options are available.
