The choice of your windows

Why choose PVC windows?

Thanks to our partner Finstral, with over 50 years of experience in the field, we can offer you a wide range of affordable PVC windows and there's something for everyone! Wood imitations, different colours, quality finishes... There's bound to be a PVC window to suit your taste and your home. What's more, PVC windows offer effective thermal insulation.

Why choose aluminum windows?

We have chosen to install aluminium windows for our customers. Although they are more expensive than PVC models, they are preferred by contractors and homeowners alike because they offer excellent thermal insulation and are environmentally friendly. In our range you'll find windows in all sizes and a wide variety of finishes. For example, you can choose an anodised, thermo-lacquered or tinted window. Bespoke windows are also available.

What type of windows should I choose?

When it comes to window installation, you can choose between aluminium casement windows, which are available in tilt and turn, hopper, Italian or tilt and turn versions... Tilt-and-turn windows are popular because they can be opened in two directions, making it easier to ventilate a room and more secure at the same time. Aluminium sliding windows are available in a range of widths and with a variety of sashes. Bay windows are usually supplied with electric shutters and remote control if required. Their large glass surface makes your interior very bright and fits in perfectly with modern houses.
