Aluminium window detail

Renowned for its strength and versatility aluminium enables the manufacture of windows with a slimmer profile, offering improved aesthetics and a larger glass surface to maximise natural light in your home.

But don’t confuse modern aluminium windows with the old cold units of the 1970’s.  Today’s aluminium windows are fitted with a thermal break – a continuous barrier between the inside and outside window frames that prevent conductive thermal energy loss. And of course TWG aluminium windows are glazed with energy efficient DGU’s and Edgetech superspacer®, keeping the interior space of your window at a more comfortable temperature.

System Features:

Attractive, slim-line profiles offer reduced sightlines.
Profiles available in either square or rounded edge options.
Fabricated using mitred corners.

Lock mechanism available with domestic style lift-up handle with adjustable, one-piece keep.
Low threshold option.
Fully weather sealed.
Available in a choice of colours including the Ral colour range and Dual colour.
