Sheerline aluminium windows are also customisable, so you can choose from a wide selection of stylistic options to make your windows unique to your home in Sheffield.

At D&I Windows, all of our products are reliably sourced and responsibly handled. We are invested in supplying our customers with products manufactured using sustainable materials, working with manufacturers who produce less waste material, and providing environmentally friendly installations. Aluminium is also recyclable, so the profiles can be reused rather than ending up in a landfill.

Thermavic® Technology

Sheerline aluminium windows feature a Thermavic® multi-chamber thermal design, which contributes towards keeping your property well insulated. Combined with high-performance double glazing, these aluminium windows offer exceptionally low U-values of 1.4W/m²K.

Market-Leading Security

The design also features a patented corner jointing method that secures the glass to the unit without any protrusions, so it cannot be forced open. This, coupled with market-leading locking systems, provides complete protection against unsolicited access to your home. They also carry PAS24 enhanced security accreditation and can be Secured by Design certification.

Slim Sightlines

Due to the inherent strength of aluminium, our aluminium windows can accommodate ultra-thin frames without compromising on structural integrity. This means that you can benefit from slim 59mm sightlines and sleek aesthetics with large scale glazed panelling, perfect for both modern and traditional homes.
