Aluclad Windows

Aluclad Windows

Aluclad windows offers new home owners an A-Rated window with low U-Values to meet the latest building regulations. This high performance Aluclad window system has a high strength factor, which allows a variety of bespoke designs both large and small. Favoured by architects is the sleek profiles that allow the maximum amount of light in. Natural solid hardwoods will enhance any home interior.

Natural Insulation

PVC is a natural insulator, and is foam filled, meaning high insulation. The wood in an aluclad window is also a natural insulator. Triple glazed glass with Low-E coated, energy efficient glass. The glass units are 44mm triple glazed with argon gas filling the cavity between each pane. All these factors combine to make a window with excellent energy efficiency and low U-Vales.

Clever Design

The clever and unique part of our design is that a foam filled uPVC profile sits between the wood and aluminium profiles to give the wood extra protection from the elements. The uPVC profile is substantial in size which gives great insulation and protection to the wood. The uPVC profile adds space between the aluminium and wood which creates a cold barrier. This is critical for aluminium clad wood windows.
