Aluminium is big temperature amplitudes resistant which means that its structure is not changed with time.  GSG uses the Greek joinery ALUMIL with an uninterrupted thermal bridge and a cold profile, which is among the best profile systems for aluminium joinery on the market, with a guaranteed quality and a modern design, meeting the European requirements for heat- and sound insulation. The cold profile provides the needed efficiency at an affordable price.
The variety of profiles and rubber gaskets makes it possible to use single glazing 4 mm or glass units up to 20 mm as well as different kinds of padding. The German casing SIGENIA can be regulated, allows two axial opening – on the vertical and on the horizontal axes; ensures housebreaking security; has two-layer anti-corrosion surface polishing. The aluminium joinery can be colored in an unlimited number of colors – it can be powder painted in the full color range of the RAL catalogue or in knot variants of wood shades: red oak, mahogany, pale or dark cherry, acacia, fumed oak, beech, etc.
