Glazing system, alumnium framing

Introduction
The Kawneer GT70 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.
