What are uPVC Windows?

uPVC Windows are a range of double and triple glazed windows manufactured from uPVC, which is a form of plastic.

uPVC stands for “unplasticized polyvinyl chloride”, which is a compound of polyvinyl chloride (PVC) and additives. It can be used in a variety of products including plastics, pipes, inks and coatings. uPVC is most commonly seen in windows, doors and conservatories.

They are the perfect choice when it comes to conserving energy, protecting your property, and giving you peace of mind. Replacing your windows with uPVC double glazed windows is a great way to improve the energy efficiency of your home and also add value to it.

Types of uPVC Windows We Provide and Install

There’s a new way to show off your windows. Introducing Windows by Ace Glazing, a match for your style, whether you like modern or classic. Choose an external colour from our collection of more than 50 shades, and we can provide high-quality uPVC windows to suit your property. Be the envy of all your friends with any of our wide collection of stunning uPVC windows from Ace Glazing, today! Our range of uPVC windows include:

Casement uPVC Windows 

Casement uPVC windows open outwards. The window is hinged at the side of the frame, and an opening pane or sashes sit alongside a fixed pane. When cranked open, the sashes can tilt to any angle. The advantage of casements is they are flexible for all sorts of different window configurations, whether you want to open them wide or keep them small, it doesn’t matter. 

Flush uPVC Windows

A thoroughly modern take on the iconic UPVC window design, Flush uPVC windows offer an easy choice for homeowners seeking a classic, yet contemporary look. They are crafted with closed-cell PVC, for a tight seal against the elements. They’re hard-wearing and easy to clean. Much like a regular UPVC window, flush windows are also made from polyurethane. However, unlike their traditionally hung counterparts, these windows come as one single unit.

Tilt and Turn uPVC Windows

Tilt and Turn uPVC windows are designed to provide a simple method for improved ventilation, light and noise reduction. Tilt and turn window frames have a unique tilting mechanism that allows you to open the sash from any angle. This flexibility makes operating your windows quick, easy and safer.

Sash uPVC Windows

Sash uPVC Windows are a British-Standard uPVC window designed with elegance and quality in mind. They have a new easy clean sash profile, which means rooms stay clean for longer with no build-up of dirt and fine particles.

Cottage uPVC Windows

Cottage uPVC Windows are simply the most affordable, best-looking and high-performing uPVC windows on the market. Their performance is unmatched and they’re extremely durable. They’re used by more remodelers than any other brand in the UK because of their high-performance, yet low cost.

Bay uPVC Windows

Bay uPVC Windows are high-specification UPVC windows that combine stylish and functional design with excellent thermal performance. Bay uPVC windows add comfort and security to your home, as they’re all backed up with the BBA’s industry-leading 10-year guarantee.

Arch uPVC Windows

The Arch window is a solid, monolithic unit. It follows an elegant, curved design and boasts the highest level of performance & durability. Arch uPVC windows are made from a high-quality PVCu that won’t crack, warp or mould – and that doesn’t require the addition of nasty chemicals to make them durable.

uPVC Windows with Triple Glazing

Triple glazing is where there are three layers of glass in a uPVC window. The middle pane is significantly smaller than the outer two, giving thermal efficiency above double glazing, whilst retaining privacy. uPVC Windows with Triple Glazing are energy-efficient, affordable, maintenance-free and you will never need to replace them again. Perfect for all homes and buildings. Our high-quality uPVC windows with triple glazing will give you a snug and secure feeling year-round. With our unique triple glazed windows, we can also help reduce your energy bills by up to 50% each year. Choose from a range of styles, colours and brands to suit your needs and budget.

uPVC Windows with Framing

uPVC windows with framing are a combination of uPVC and timber. They still have all the great features of uPVC, are easy to clean, draught-proof, energy-efficient and can be fully customised to create stunning window designs – but they also have an authentic timber frame for a traditional appearance.

At the beginning of a new construction project, it is important to invest in high-quality windows and doors. That’s why we offer our uPVC Windows with Framing options.

uPVC Windows with Smoothweld

Smoothweld uPVC windows are a high-performance window that combines the energy efficiency of double or triple glazing with the easy cleaning convenience of maintenance-free uPVC frames.

 Smoothweld technology provides an interference-free bond between the frame and glass to reduce draughts and guarantees many years of draught-free, no-maintenance living.

In other words, you can enjoy both excellent thermal performance and low condensation.

uPVC Windows with Georgian Bars

Often used as a secondary security device, Georgian bars can help to deter potential intruders. uPVC windows with Georgian bars are manufactured from high-density polyvinyl chloride (uPVC). The frames of the uPVC windows are manufactured to fit within the existing opening such that it is not required to make any additional openings in the property. These uPVC windows with Georgian bars fit inside the structural woodwork and give a traditional appearance to your home. This product is an inert material in relation to any possible development of mould or dampness.

Triple Glazing

Triple glazing uPVC windows are made from a unique combination of plastic and glass. A triple glazed window has an insulating and weather-proof layer of air that sits between two panes of toughened glass. They are one of the most energy-efficient materials which can help to create a comfortable and healthy living environment.

Triple glazing uPVC windows are three times more thermally efficient than a standard double glazed window, making them extremely effective in reducing heat loss within your home. With uPVC windows from Ace Glazing London, you can improve the value of your property by using less energy which will save you money on your energy bills.

Secondary Glazing

Secondary glazing is the process of adding an additional layer of glass on a window’s existing single pane. Adding a second layer of glass increases insulation to lower your heating and cooling costs by up to 10%. Before you know it, you’ll be looking for more ways to increase efficiency around your home as the money saved adds up. 

Our secondary glazing windows are the perfect uPVC solution to keep the cold out and the heat in. The secondary glazing panels on our windows are made of four mm laminate, that is both strong and secure. The units are independently tested for security as well as being double-glazed. Call us today to learn more about secondary glazing and how uPVC windows can help you save money!
