Alu Clad Windows

Alu clad windows and doors combine a timber interior with an aluminium exterior enhancing the style and design with the attractive benefit of minimal maintenance. The combination of the powder coated Aluminium on the outside and the warmth and beauty of timber to the interior makes alu-clad windows and doors exceptionally weather resistant and also very thermally efficient.

Alu clad windows and doors are sometimes referred as timber clad windows and are possibly the fastest growing window type in the UK. With the benefits of an Aluminium exterior, Alu-clad windows and doors require little or no external maintenance and maintain their look for many years. All our Alu-clad windows come polyester Powder coated and can be fabricated in the colour of your choice with a satin, gloss or matt finish.

 Top grade laminated timber is used to create a robust design, during manufacture the timber has a base coat protection applied prior to cladding ensuring maximum durability in all weather. The Internal timber can be painted to a colour of your choice or stained to show the natural grain of the wood.

 All our Alu-clad windows can be made in many styles of frame, our most popular styles include:  Traditional Sliding Sash Windows, Tilt and Turn Windows or Traditional Casement Windows. we also offer "curtain walling" where large glass expanses of up to 2 metres by 3 metres can provide a stunning view of the outside world from the comfort of your home or building.
