GT70 Slimline Renovation Window

Description

The GT70 Slimline Renovation Window is an elegant aluminium fenestration solution, designed specifically to replicate the appearance of steel windows. Suitable for installation in new build or refurbishment projects, the GT70 window combines the optimum technical performance expected of today’s aluminium windows with the fine sightlines characteristic of original steel windows. These slender sightlines are enhanced further by optional bevelled designed feature caps, adding a unique sculptured effect to the external surface of the building.

Features/ benefits:

  • Fine sightline characteristics of steel windows, providing a suitable replication for steel windows with additional benefits associated with aluminium, such as the high strength to weight ratio.
  • Suitable for composite and ribbon windows.
  • Option for open-out or open-in to meet project design requirements and user flexibility.
  • A range of structural and coupling mullions available.
  • Special bevelled beads, or feature caps, add a unique sculptured appearance to the building.
  • Concealed drainage system to enhance the building’s aesthetics.
  • Accommodates glazing of up to 54 mm for inside glazed or 33 mm for outside glazed.
