Aluminium Windows

Aluminium double glazed windows are just as energy efficient as uPVC, thanks to a thermal break that reduces heat loss through the frame. Aluminium also boasts slimmer frames and a sleek profile that makes it an ideal material for modern properties.

Casement, tilt and turn, and pivot windows are available in aluminium from K Glazing. Aluminium frames can be coloured in any RAL colour, with dual colouring to match both the inside and outside of a house.

uPVC Windows

uPVC is the most popular material for window frames. Weatherproof and energy efficient, modern uPVC double glazing will reduce heat loss from your home, cutting energy bills substantially.

Casement windows and tilt and turn windows are available, with two different frame styles. You can choose uPVC double glazing in White, Rosewood, Cherry, Irish Oak, Cream, Chartwell Green, Anthracite Grey and Black, as well as any RAL colour!

Timber Effect Windows

Residence 9 windows offer high level energy efficiency, durability and low maintenance like uPVC windows, but with the charming appearance of a timber frame. These wood-effect windows are made to measure and each one hand assembled, like traditional joinery.

Available with a traditional wood grain finish in a range of traditional colours you can get a frame like painted timber, but completely maintenance-free. You can get a timber effect finish from light colours through woodgrain colours, to greys and blacks, including:

White Grain, Clotted Cream, Cotswold Biscuit, Cotswold Green, English Oak, Irish Oak, Golden Oak, Rosewood, Silver Oak, Painswick Grey, Corse Lawn Grey, Eclectic Grey and No. 10 Black
