Luxurious, slimline aluminium windows from one of the world's leading manufacturers

Super Slim

The Reynaers slimline aluminium window has one of the slimmest profiles on offer, meaning you get an ultra modern window that focuses on glass area as opposed to thick frames. The clean, subtle lines of the frame make this an ideal choice for contemporary projects.

Perfect For
Large Glass

Despite the slim outer frames, aluminium is the strongest material available for windows. This means the Reynaers slimline window is capable of achieving large glass areas, perfect for picture windows, glazed wall effects and any modern design where more glass is the brief.

U Value as
low as

Our slimline windows achieve terrific energy ratings that meet new 2022 building regulations, and there are even upgrade options available to achieve energy ratings as low as 1.1/m2K.

Glued Corners
= More Strength

All of our Reynaers slimline windows have the corners bonded with epoxy glue, as an additional quality measure. 80% of the windows strength comes from the corners, and a common issue with lesser brands is the corners can weaken over time.

Colour Range

There are over 450 shades and finishes available on the our Reynaers windows, some by special request. Stock colours (White, Anthracite Grey & Black ) are available for faster delivery, or wait a little longer for bespoke colours and finishes such as metallic and anodised paint.
