FAQs

Your Questions Answered

We know that choosing the right home improvement is never easy, so we’ve listed some of the most common questions about casement windows to help you make the right choice.

Ask Us

What are casement windows, and how do they differ from other window types?

Casement windows are hinged windows that open outwards. They are one of the most popular window styles due to their simplicity and versatility. Unlike sliding or fixed windows, casement windows swing open like a door, providing excellent ventilation and unobstructed views.

Are uPVC casement windows energy efficient?

Yes, our casement windows achieve an A-rating for energy efficiency as standard. The multi-chambered frames and high-performance double glazing work together to significantly reduce heat loss and help lower your energy bills.

What colour options are available?

We offer an extensive range of colours, from classic white to contemporary greys and authentic woodgrain effects. Popular choices include Anthracite Grey, Chartwell Green, and Golden Oak. We also offer dual colour options, allowing different finishes for interior and exterior surfaces.

What maintenance do uPVC windows require?

uPVC windows are very low maintenance. Regular cleaning with soap and water, along with occasional lubrication of moving parts, is usually all that's needed. Unlike timber windows, they won't rot, warp or need repainting.

How long will my new uPVC casement windows last?

Quality uPVC casement windows typically last between 20-30 years when properly maintained. All our windows are built to withstand the North East weather and come with comprehensive guarantees for your peace of mind.

Which is better, tilt and turn or casement windows?

The choice between tilt and turn and casement windows depends on your needs and preferences. Tilt and turn windows offer versatility, allowing you to tilt them inwards for secure ventilation or fully open them for easy cleaning and maximum airflow. Casement windows, on the other hand, open outward on hinges, providing excellent ventilation and a classic appearance. If you prioritise flexibility and ease of maintenance, tilt and turn windows are a great choice, whereas casement windows are ideal if you prefer a more traditional look with wide-opening functionality.

Are casement windows old-fashioned?

Casement windows are not old-fashioned; they have a timeless appeal and can be tailored to suit both traditional and modern homes. While they have been used for centuries, contemporary designs offer sleek frames, energy efficiency, and versatile options like flush and French casements. Their functionality, customisable styles, and ability to complement both new builds and renovations make them a popular and practical choice.
