This GGL 3070 window comes has now replaced the discontinued GGL 3050 Window and comes with the upgraded "Safety 70" Glazing which has a laminated inner pane for enhanced safety.
The window utilises Thermotechnology to cut your energy bills. EPS
Insulation is used throughout the window along with Thermally Modified
Timber for a super energy efficient finish as standard.
The same bracket is now used for both recessed and standard installations, with a red / blue colour coding system, to make for much simpler installation. Click-on covers also aid the installation process and reduces the number of screws required.
The pane size has been increased by reducing the width of the frame
which allows more daylight and warmth in through the window, increasing
the window's energy and light efficiency.
All windows also come with an aluminium ventilation flap to allow fresh air in even with the window is securely closed. Specially designed to allow you to see whether the flap is open or closed from any angle in the room.
