The GT6700 incorporates dual thermal strut technology for optimum thermal efficiency and low U-values. It is AAMA AW rated in all configurations with minimum air leakage, high water resistance and impressive design pressures.
This new window system has both a slim sightline as well as an equal sightline option dependent on intended use and preferred aesthetics. The window incorporates a deeper sloped glazing bevel for a more authentic historic look and the strut framing allows for an optional dual finish.
A euro groove frame design allows for easy accessory attachment. Both true and applied grids are available and a fixed over operable intermediate design offers minimal sightlines. Optional roto operator or single lever operator and limit devices are also available.
