infinity uPVC casement windows

When it comes to upgrading or replacing windows, homeowners across Britain are increasingly choosing casement windows, and it’s not hard to see why. The casement style is the most popular in the UK. Why? Because casement windows offer a winning combination of practicality, aesthetics and performance. At Emerald Windows and Doors, we’ve seen first-hand how casement designs continue to suit homes of every type, from period properties to attractive new builds.

Versatile design to suit any property

One of the main reasons casement windows are so well loved is their versatility. Whether you’re enhancing a traditional cottage or finishing off a contemporary extension, this window style blends beautifully into its surroundings.

Casement windows are hinged at the side or top, and can be manufactured in single, double or even multi-panel formats. Options like flush casement windows offer a more streamlined appearance, sitting level with the frame for a modern, minimalist look. For wider openings, double or French casement windows create a clear, mullion-free view and maximum airflow.

At Emerald, our casement windows are available in uPVC, timber effect and aluminium, each with its own distinct qualities. uPVC casement windows are a popular low-maintenance option, while timber effect adds timeless charm and aluminium offers a contemporary edge. A wide range of colours ensures every homeowner can find a finish that fits.

Practical benefits for modern living

As well as looking the part, casement windows offer a host of practical advantages that appeal to today’s homeowners. These include:

• Excellent ventilation – Casement windows open wide, letting fresh air flow through your perfect space with ease

• Superior energy efficiency – Double or triple glazing and a secure seal reduce heat loss and draughts

• Security and peace of mind – Reinforced hinges and advanced locking mechanisms protect your home

• Clear views – Minimal framing gives you an unobstructed outlook

Whether you choose uPVC, aluminium or timber effect, all our casement windows come with a 10-year guarantee against faulty materials or workmanship, demonstrating our commitment to a higher standard of window.
