Why choose uPVC windows?

We’ve partnered with Finstral, which has over 50 years of experience in the field, to offer you a wide range of affordable uPVC windows to suit every taste.

Imitation wood, multiple shades, quality finishes… There’s a uPVC window out there to suit your taste and your home.

uPVC windows also provide effective insulation properties.

Why choose aluminium windows?

We have consciously chosen to install aluminium windows for our customers.

While they are more costly than their uPVC counterparts, they are the preferred option for contractors and individuals alike because they provide excellent thermal insulation and are also more environmentally friendly.

Our range includes frames that come in many different sizes with numerous finishes.

You can opt for the likes of anodised, thermocoated or tinted finishes, among a whole host of other options. We can also create made-to-measure windows.

What type of window should I choose?

For your window installation, you can choose from the following options:

Aluminium hinged windows come in pivot, hopper, top-hung outward or tilt and turn styles.

Tilt and turn windows are popular, as they give you two different ways of opening the window, to allow air to circulate in a room whilst still remaining secure.

Simple or in-line, sliding aluminium windows come in different widths and with a number of opening options.

Bay windows usually come with electric shutters, with the potential for remote control.

The large glass surface allows natural light to flood into your home and is the perfect choice for houses with contemporary styling.
