A-Rated Windows for Style, Warmth and Value.

The right choice of energy-efficient window is integral to the style, warmth and security of your home. uPVC double glazing has been the most popular choice since double glazing was introduced in the 1970s. Early versions were certainly much better than the metal Crittal windows that they often replaced but still lacked security, colour stability and thermal efficiency.

The double glazing industry changed in 2010 with more people prioritising their homes as they had more access to information from the internet. Competition among double glazing firms meant that any company who wanted to compete had to supply windows and doors that met the widest demands for style choice, security, thermal efficiency and value.

If uPVC double glazing is not the obvious choice for your windows, which material should you choose?

Aluminium windows are just as versatile and have a look that is very different from uPVC or wood. They have slimmer frames and are often chosen for more modern buildings. If your home is in a conservation area, you may be restricted to choosing wooden windows. If your preference is for the wood look but you want the traditional look, consider flush casement uPVC windows. Flush windows look just like wood, and even have the option for woodgrain finishes, but have the styling of traditional windows.

Regardless of which material you choose, advances in engineering over the last ten years means that any modern choice of quality double glazing products will serve your purpose well.

Windows Doors Cardiff - uPVC Double GlazingTypes of uPVC Double Glazing.

Windows, doors and conservatories can be made of different type of double glazing options. Most doors have fixed glazing panels but the windows will have a choice in the way that they open. You will largely be led by the style of your home in choosing which type of windows, the shape of the profile and any decorative features such as Georgian bars and stained glass. Once you have chosen the material and range, we will then help you to decide which windows should be open or fixed. You don't have to have the same as before. Consider how efficient your windows are currently for airflow and if you have windows that you never open. This picture is from a South Wales installation that we completed last years. Originally, there was an opening window at the top in the middle. It made sense to put the openers on the side window, leaving a large picture window that gives more sense of space.

Casement Windows.

Energy-efficient Casement windows are the most popular style of window. This option will always be available regardless of whether you choose uPVC, aluminium or timber. 

Casement double glazed windows are popular because of their flexibility, both in choosing the layout and decorative features. Usually, unless there are reasons to use a different style such as planning restrictions, most people choose casement windows.

Generally in the Cardiff area, we install casement or sash windows.

Casement style windows are characterised by the fact that they are hinged, most often on the side but also on the top and even sometimes on the bottom.

Sash Windows.Sash uPVC energy efficient Windows installed in Cardiff

Sash windows are popular in Cardiff due to a large amount of traditional-style homes. Usually, if a home already has sash timber windows with concrete supports, it makes sense to replace them with modern style sash uPVC windows. The modern sash double glazing combines the benefits of traditional style with the best in thermal efficiency. We'll be happy to discuss options with you if you hope to replace your sash windows with a different style such as casement windows.

What is a Sash Window?

A sash uPVC window features two glass panels that slide vertically thereby allowing for better airflow. The word “sash” refers to a frame that holds the glass. A sash window typically features two sashes that slide up and down. You will no doubt see a lot of these as you drive around South Wales.

Our vertical sliders are stylish and made of quality materials. What’s more, they are easy to clean and maintain. If you are looking for a traditional look, we can fit your sash windows with Georgian bars or even astragal bars before finishing them with sash horns for that added character. To find out more, visit our page for sash windows.

Tilt and Turn Windows.

Tilt and turn windows make the most of their glass panels to let light and air flood in, for a bright and fresh environment. Plus, keeping your windows clean and bright is always an easy, stress-free task. The innovative tilt and turn mechanism offers wide side-opening for safe and simple cleaning from the inside of your home. Open wide in the summer to bring the outdoors in and, when it’s cold and wet outside, keep your home well-ventilated using the intelligent top-fixed tilting mechanism. To find out more, visit our page about tilt and turn windows.

Flush uPVC Double Glazing.

Flush windows are the 'new kid on the block in uPVC windows'. They are popular with those who want the traditional look of wood. Flush windows fit this requirement perfectly as you would have to be close to realise they are not wood. They are characterised by the same block timber look and are even being accepted in some conservation areas. While flush windows can look good on any style of property, they are proving particularly popular for traditional homes. Flush window profiles offer an alternative to wooden windows and doors that is sympathetic to older styles but with the benefits of modern technology.

uPVC colour Chart for energy efficient windows available in South WalesuPVC Colours.

In Cardiff and throughout South Wales, the most popular colour for windows is white. Our uPVC double glazing products are available in a variety of colours and the best colour for you very much depends on the style of your house. Naturally coloured windows cost a little more but well worth it as they transform a home.

To be honest we've never installed red windows but all of the other colours look fabulous. Anthracite is the second most popular colour but Chartwell Green is coming up a close third lately. 

At Heath Windows and Doors, we'll take the time to help you make the right choice.

How Much do New Windows Cost?

The cost of your made to measure replacement windows will depend on several factors. The quality of your new windows certainly has an effect on the price, both in the materials used, the fixings and the installation. The difficulty for you as the customer is knowing the difference. Windows look the same when they are fitted. It's only in time that you start to see windows dropping because the hinges aren't sturdy enough or frames bowing because the aluminium or steel inside the frame is not strong enough. The fitting can also make a difference. Your windows need to move smoothly and this relies on level fitting. Unfortunately, the industry is known for sub-contractors who value speed over quality. That's the reason that as a premier window supplier we fully employ our installation engineers. They know that quality takes precedence and will take their time to ensure the perfect installation. In addition, all of our windows, doors and conservatories carry at least a 10-year guarantee for your peace of mind.

Sometimes the perception of cost is related to house value. There is no difference in cost whether you live in Cardiff or anywhere else. A single uPVC window costs the same whether you have a 2-bed bungalow in the South Wales countryside as it does for a 6-bedroom house in the middle of Cardiff.
