Aluminium sash windows are thermally broken to help reduce heat loss and condensation as well asoffering a slim elegant profile suitable for replacing traditional box sash windows in sensitive conservation areas.

Summit Double Glazing's Aluminium Sash Winodws are more resistant to warping, twisting or sticking when subjected to the elements. They are also virtually intruder proof. Additionally aluminium neither absorbs water, rots or rusts.

In the last decade aluminium windows have decreased in popularity mainly because it became a more expensive alternative than PVCu. Additionally the insulation qualities of aluminium are quite poor when compared to PVCu and it was often susceptible to condensation. This lack of insulation is partly remedied by installing a 'thermal break' in the aluminium frame. If you chose aluminium for your replacement windows we would only suggest you consider windows with a thermal break.

Aluminium is a good choice for commercial locations and any situation where strength is a major issue. 

Aluminium windows can be fitted as 'direct fix' - i.e. directly against the brickwork or alternatively (and more often) into a hardwood subframe.

Decorative features are further enhanced by the use of ovolo shaped beads, equal sightlines and a range of decorative Georgian fret and authentic traditional Georgian bar options. For those who prefer a true timber appearance, the window is available in mahogany, rosewood or light oak options. Or with a timber appearance to the outside face with a white finish inside, to maintain a light airy appearance to the interior. Please click here to see Sash Window Layout.
