Today, many homeowners, builders and architects place special emphasis on external durability and low maintenance. Our specialist timber windows and doors with aluminium cladding offer an option that is both low-maintenance and strong - combining the beauty and craftsmanship of our natural timber windows and doors with a modern, durable, low maintenance aluminium clad external finish.
All of our aluminium clad products boast superior protection against the elements, with a tough exterior that provides excellent thermal insulation and can withstand even the most extreme weather conditions. This allows you to enjoy our products for many years without worrying about maintenance, or repeatedly recoating the frame of your window or door.
22 Standard RAL colours or an additional charge for none standard RAL.
Marine options
As with all aluminium salt spray is a major concern to the longevity of the paint finish. The standard paint finish used on the external cladding of these windows is 60 Microns, thicker than that applied on UK windows. There is a marine finish upgrade which is a 60micron primer + 60 micron top coat finish.
Anodised finished offer a higher level of protection against corrosion than painted finishes and this option is available.
The weakest point on any aluminium product are the cut corners, there is an option to have these welded and then the whole window powder coated.
