      Product Features

      GT 70 S: Classical outside aspect, modern comfort

      The GT 70 S is a component of the RT 52, RT 62 and RT 72 modular aluminium window and aluminium door systems. The GT 70 S aluminium window system is especially recognizable by the slim profile, thanks to a width of 39 mm. Because of this, the GT 70 S is highly suitable for steel renovation. However, the system is also regularly applied to new building and construction projects.
       
      Residential homes and commercial premises in need of renovation are often characterized by having slim steel frames. These frames provide the buildings with a characteristic aspect, but they imply serious insulation limitations. Alcoa Architectuursystemen has the solution ready to go, the GT 70 S window system. This system offers the same aspect, but with the insulation value, functionality and durability compatible with a modern aluminium system.
       
      The system profile of the GT 70 S series can invisibly replace currently installed materials, not only steel, but also wood and plastic can be replaced by aluminium. With all of aluminium's positive characteristics. The authentic character of the building is not disturbed, increased burglary and fire resistance become possible and maintenance becomes practically unnecessary.
