The ALTHERM Range
Sweeping upgrades and modernisations to most products occurred in 2000 and again in 2008. These refinements have been design and performance driven, especially to ensure effortless compliance with Building Code upgrades on thermal efficiency.
In addition to the popular residential range, we also offer a complete portfolio of high performance products for larger format windows and doors characteristic of architecturally designed homes – the METRO SERIES and APL ARCHITECTURAL SERIES. Higher thermal efficiency can be achieved by upgrading to ThermalHEART technology within the ALTHERM Residential and METRO SERIES ranges.
