Who doesn’t love a classic white colour? But you may want something different, and if you do, you won’t be disappointed by the diverse selection of finishes that we have for our many window products. We employ a colouring process that enables us to create colours that you just don’t get elsewhere.

If you want a crystal-clear view of the outdoors or value your privacy, there will be a glazing option that fits your objective. You can always speak to one of our consultants and get their opinion on which glazing they believe will best satisfy your requirements.

A first-hand look at our traditional and contemporary-styled handles will make you appreciate the level of craftsmanship that has gone into them. Our craftspeople dedicate hours to fashioning every handle.
