Aluminium Windows

Upstairs offices, flats over shops and the side walls of industrial units often still have tired timber or early PVC-U windows that leak heat and stick shut. Slim aluminium windows let in more light, keep the weather out and need almost no upkeep.

Window types

- **Fixed lights.** Panes that do not open, used where the view or light matters and air comes from elsewhere. - **Top-hung.** Hinged at the top and opening outwards at the bottom, a good choice for offices because rain runs off. - **Tilt-and-turn.** Tilts inwards at the top for air, or swings in fully for cleaning from inside, useful on upper floors. - **Sliding.** Panels slide past each other, handy where an outward-opening window would hit something.

Heat and noise

Frames with a thermal break and double-glazed units keep heat in and road noise out. Where the building has to meet Building Regulations for replacement windows, we choose frames and glass that comply and tell you the figures.

Weather tightness

Commercial windows are tested for how well they keep out air, water and wind. We fit them with the correct fixings and seals so they perform as tested, and pay particular attention to the joint between frame and wall, where most leaks start.

Security

Ground floor and accessible windows can have locking handles, restrictors that limit how far they open, and laminated glass. Restrictors also matter on upper floors where children or vulnerable people may be present.

Planning

Replacing windows in a conservation area or on a listed building often needs consent, and councils may ask for a particular frame shape or colour. We tell you at survey.

Colour

Any RAL colour is available, and frames can be one colour outside and another inside.
