Quality UPVC Windows for Every Home

At Greenland Home Improvements, we supply and install the finest UPVC windows across the UK. Whether you’re looking for classic casement, sleek flush or traditional Victorian sash windows — we have the perfect solution for your home, backed by our 10-year guarantee and installed by our FENSA-certified team.

Casement Windows

Casement windows are the most popular choice for UK homeowners — and it’s easy to see why. They open outward on a side hinge, offering excellent ventilation and a classic, timeless look that suits virtually any style of property. At Greenland, our UPVC casement windows are precision engineered with multi-chamber profiles and argon-filled double glazing, delivering outstanding thermal performance and helping to reduce your energy bills. Every window is fitted with high-security multi-point locking as standard, so you never have to compromise on safety.

Modern & architect-style

Flush Windows

If you’re after a clean, contemporary look, our UPVC flush windows are the perfect choice. Unlike standard casement windows, the sash sits perfectly flush with the outer frame — creating smooth, seamless lines that suit modern homes, new builds and stylish extensions. The result is a minimalist, high-end finish that looks just as good from the outside as it feels on the inside. All the energy efficiency and security benefits of our full UPVC range, delivered in a beautifully understated style that’s growing fast in popularity across the UK.

Period & traditional homes

Victorian Sash Windows

For homes that deserve to keep their character, our Victorian sash windows are the ideal solution. They beautifully recreate the elegant, sliding aesthetic of traditional timber sash windows — but with all the modern benefits of high-quality UPVC. They slide vertically for ventilation, maintain the period look of Victorian, Edwardian and conservation area properties, and are fully compliant with most local authority planning requirements. You get the charm of the original, without any of the maintenance headaches of timber. A truly popular choice for period homes across the UK.
