We appreciate that the finished product is not always the reason why you would chose a GM Windows sash windows. A lot of other factors are considered such as price, quality and delivery times, however we would like to bring your attention to a few of the intricate aesthetic detail which we think sets our windows apart from the rest of the competition.

The Renaissance profile system that we manufacture our sliding sash windows from is unique. It is relatively new as far as profile systems go and was originally designed about 10 years ago taking all of the best elements from the windows systems around at the time in an effort to create something truly unique in the market plac.

At GM Windows, we want to offer our customers complete adaptability and versatility. Because each of our PVC-U window installations is tailored to suit its specific location, no two are exactly the same. And to make sure that every window completely fits in with its surroundings, we offer a contemporary colour range to match every style. GM Windows & Doors Options Colour Range has been selected with modern homeowners in mind. The Cream White is a warm cream colour that complements a range of styles, but is ideally suited to both modern and traditional red brick homes. A new addition to the range is Agate Grey, a subtle blend of beige, green and cream which we know will prove very popular on new and renovated homes, especially barn conversions.
