Tight Corners

Sheerline’s state of the art construction means that the screws are placed inside the mitre joints, creating perfect 90° angles without any protrusions. These windows are perfect for refurbishment because they are easily adjustable.

What makes D&I aluminium flush windows stand out from the crowd is the seal seal in the glass. This creates a ‘beadless’ window, this adds an extra level of security making it difficult for intruders to break in. So when you install our aluminium casement windows, you get peace of mind as standard. 

Enhanced Security

Harrogate residents, like the rest of the UK, are keen to keep their home secure and safe. With this in mind our aluminium flush windows have multi point locking systems. These strong locks and the rigid nature of aluminium ensures your home and family are safe. 

These aluminium flush windows are made with extra space in the frame for ease of installation with multi point locks. These locks won’t protrude from the frame and ruin your lovely sightline. Instead, you’ll have aesthetic and secure windows for your home.

Thermally efficient

Single glazing is out and double or triple glazing is in. Double glazing is more eco-friendly than traditional forms as it helps keep the heat inside your home, that means you use less energy, which in turn means you save money and help save the planet. With double glazed aluminium casement windows, your U-values can be as low as 1.4 W/m2K, better than government standards.

Our aluminium flush windows also keep moisture and draughts out of your home. With polyamide thermal breaks that help ‘break’ heat loss, you’ll have better insulation than ever.

Slim Sightlines

Aluminium is a remarkable material as not only is it extremely thermally efficient it also very easy to look after. Its natural properties allow the manufacturers of our aluminium flush windows to use less of it when they are building the windows. This means you get smaller, sleeker frames, these will give any Harrogate home a modern look and feel.

If you have a more traditional home, you might want to choose one of our woodgrain finishes. This allows you to get the thermal efficiency form a modern aluminium flush window but with a more traditional look.
