This depends on how close you get. From a distance, a ventilation window looks like ordinary double glazing. We make and supply windows in the same style and design as other windows in your property.
Take a closer look and you can see slight differences, including the inner pane, the larger space between the panels, and our highly efficient valves.
We can manufacture your windows to a design of your choice. You may wish to replace architect-designed windows, with or without mullions and muntins. We also produce modern timber/aluminium windows to order. Check out the full range of options in the Products tab.
