the window range

Metro Series windows have strong, heavy-duty profiles to ensure that large sized formats  perform with ease under a wide range of weather conditions. But there is no compromise on aesthetics – all products are notable for their clean, flat surfaces, which are the preference of contemporary designers.  

awning windows

Opening windows have been designed to sit flush with the outside and inside face of the frame for a smooth, continuous look in the closed position. (Other options are possible, including one which overlaps the frame.)

sliding windows

For the ultimate in a robust slider the Metro product uses the sliding door frame. Stiffening boxes on interlocker stiles and mullions are flush in the closed position for superior aesthetics.

bi-fold windows

 The Metro bi-fold window is bottom-rolling, with the weight carried on the sill  to ensure ease of operation over the long term.
