uPVC Windows

uPVC (Ultra-High Density Polyvinyl Chloride) is a modern material and a popular alternative to timber with a whole list of benefits for homeowners. In new-build projects, uPVC currently accounts for 80% of all installations due to its strong and durable properties. What’s more, uPVC is considerably cheaper than other materials such as aluminium and timber.

Types of uPVC Windows

Casement Windows

Casement windows are hinged on the side and open outward to the left or right. In a modern casement window a combination of types can be fitted into a single frame such as the common Awning (top hung) sash. Casement windows are usually taller than they are wide and their entire sash opens to provide top-to-bottom ventilation.

Double Hung Windows

Double Hung uPVC windows offer a simple, contemporary style solution to suit modern properties. Double hung windows have two sashes in a single frame, which slide up or down to provide ventilation. They are often placed adjacent to patios, decks and walkways. The sash tilts in to provide secure ventilation as well for easy cleaning.

Awning Windows

Awning windows are hinged at the top and open outwards. Usually wider than they are tall, their entire sash opens to provide full side-to-side ventilation, allowing them to catch breezes from any direction. Awning windows are a good choice for placement above sinks or countertops, because they open by cranking a handle, which, for example, is easier than leaning forward while lifting the sash of a double hung window.

Gliding Windows

Gliding windows feature two sash, with at least one of the sash sliding horizontally past the other, and they offer the advantages of double-hung windows with a more contemporary look. A gliding window is the perfect space saving solution when a projecting window could interfere with walkways, patios or decks. Moreover, due to the sliding mechanism, you can easily clean the exterior glass from inside your home.

Benefits of uPVC

Low Maintenance 

One of the biggest advantages of installing double glazing is that it significantly increases the insulation within your home. According to the Energy Saving Trust, replacing single glazed window with B-rated double glazing can help create an annual saving of around £170. However, the effectiveness of double glazing will depend on three different factors; the window rating, quality of installation and frame material. The British Fenestration Rating Council (BRFC) have devised a Window Energy Rating Scheme (WERS) that works in a similar way to the Energy Rating label, which is more commonly found on household appliances likes refrigerators and washing machines.

Energy Efficient

Double glazing has been designed to ensure heat stays inside your home. During cooler months, double glazing helps lower energy consumption, thereby reducing energy bills. However, the heat retention of a double glazed window is determined by the energy rating of the window.  

Enhanced Security

Apart from lowering energy consumption, double glazing also helps to insulate your home from outside noise. For example, in a busy city environmental noise is ever-present meaning occasional noise disturbance can be an issue. Installing double glazing helps to protect homeowners from noise pollution, and create a relaxed atmosphere free from unwanted external noise.

Acoustic Performance

Double glazing is well known for its ability to reduce outside noise levels. Simply replacing your single glazing with uPVC double glazing will help reduce the penetration of outside noise by up to 36 decibels.
