uPVC Casement Windows

uPVC casement windows are hinged windows that open outwards, similar to a door. They are made from unplasticised polyvinyl chloride (uPVC), a durable and low-maintenance material. The structure of these windows typically includes a frame, a glass pane, and a hinged sash that swings open and shut. 

These windows operate by a simple mechanism. When you turn the handle, the sash swings outwards, allowing fresh air and natural light into your home. When closed, the sash forms a tight seal against the frame, preventing drafts and heat loss.

Energy Efficiency

One of the main advantages of uPVC casement windows is their energy efficiency. Thanks to their airtight seal, these windows can significantly reduce heat loss, helping to keep your home warm in winter and cool in summer. This can lead to substantial savings on your energy bills. 

Deceunick’s 2500 uPVC casement windows have a wide surface area. This allows us to fit seals into each profile to enhance their thermal performance and reduce exterior noises.

Why uPVC Casement Windows are Perfect for Jersey

Jersey’s weather conditions can vary, with mild winters and warm summers. uPVC casement windows are well-suited to this climate, offering excellent thermal performance and weather resistance.

In addition to their practical benefits, these windows can also enhance the aesthetic appeal of Jersey homes. Whether you live in a modern apartment or a traditional cottage, uPVC casement windows can complement your property’s architecture and add a touch of elegance.

uPVC casement windows are also known for their durability and low maintenance. Unlike wooden windows, they do not rot, warp, or require regular painting. A simple wipe with a damp cloth is usually enough to keep them looking their best.

Furthermore, their sound insulation properties can help to reduce noise pollution, making them an excellent choice for homes near busy roads or in noisy neighbourhoods.
