Aluminium in Brighton

Slimmer frames, more light

Slimline aluminium casements have frames about half the depth of a uPVC window, so more of the opening is glass. They suit the 1930s houses of Withdean, Hove Park and Patcham, which were built with metal or slim timber casements in the first place, and the rear extensions and garden rooms added to older houses across the city.

Frames come powder-coated in anthracite, black, white or a softer colour such as grey-green, with a different colour inside if you want one. There is nothing to paint.

Choosing

Three questions before you choose aluminium

Is the house in a conservation area?

On the street side of an Article 4 house, aluminium in place of timber sashes is unlikely to be allowed. At the back, it often is.

Casement or tilt-and-turn?

Side-hung casements suit most houses. Tilt-and-turn windows open inwards and suit flats where the outside is hard to reach.

Which colour?

Anthracite is the common choice. White suits rendered 1930s houses, and dual colour lets the inside match the room.

Cost

Is aluminium cheaper than timber?

Yes. Aluminium is cheaper than timber, and once it is in there is no repainting. It does cost more than uPVC, and the prices page shows what a single aluminium window and a whole 1930s house typically come to.

Every job is priced on its own: the figure depends on the sizes of your windows, how many there are and where they sit, the access, and the materials, colours and hardware you pick. A free home visit gives you the exact price for yours.
