UPVC Sliding Sash Windows

UPVC Sliding Sash Windows - Harefield Windows

Sash windows date back to the 17th century; they are still a popular choice today. A classic sash window design has three by two panes on both sashes which gives the appearance of six by six panes.

In the old days, sash windows were made from wood and had single glazing which presented a number of disadvantages. First, the moving parts were quite high maintenance and the wooden frames were prone to rot in wet conditions. Secondly, single glazing sash windows weren't energy efficient as they did not keep the heat inside.

The double glazing offered by Lifestyle can help you save around £150 per year on your energy bills as double glazing, as the name suggests it, consists of two sheets of glass which offer a high level of insulation. In order to address the rotting issue, our sash windows are designed using modern and energy efficient UPVC materials.

Our range of sash windows has all the marking of the traditional sliding sash windows our customers are looking for and meet all the necessary building regulations so they are a great alternative for some new build properties looking to create that sliding sash appearance.

Our sash windows are ideal for any season and come with some new features which allows for a tilt-open or an opening of both sashes.

All our sash windows are available in a choice of colours: white, white grain foil, cream grain foil, oak foil, mahogany foil, rosewood foil so whatever the style of property, colour of brick or personal choice, we have a sliding sash option that will meet your needs.

We standardise our sliding sash windows as an ‘A’ Energy Rating to conform with current building regulations. This means you can be sure all our sliding sash windows will be as energy efficient as they are attractive.

With modern technology these windows have an improved energy saving capacity with the invention of the Thermal Break.

Outer frames are available to fit into existing timber sub-frames or now the more modern application of direct fix, straight into your existing brick aperture.

Low Maintenance

Your new windows are protected by a tough and resilient powder paint coating or hard anodised surface. Both finishes will give years of excellent service with only a minimum of maintenance. They are resistant to pollutants and the dirt and grime that can discolour and stain other window materials

Style without compromise

Add a luxurious appearance in either a modern of traditional theme. Your new windows can be tailored to complement your home's style and character with a shaped vents and a range of colours to choose from, including black outside and white inside. Our most popular colour is the gleaming high gloss, brilliant white, that will keep its good looks for years with very little maintenance. You choose exactly what you want and we can make it.

Bays & Bows

Bay windows require extremely strong sections, but to maintain the character of your home they must also be slim and attractive. Aluminium combines all these features and has proven ability to perform successfully for over 30 years.

Equal sight lines

Give your home a further dimension in style and character by creating a symmetrical and well-balanced look that is appealing to the eye. We recommend the use of imitation vents in the areas of fixed glass to give the special appearance. Aluminium is perfect for the effect because the slim sight lines avoid the bulky look that is typical of other framing materials.

The paint or stain finish applied to our product range is of an exceptionally high standard. Each timber product undergoes a 4 step finishing process. The assembled product is treated to protect end grains from moisture ingress. A base coat is applied by flow coater and two top coats are applied to the correct micron thickness by our factory controlled spray line.

Our paint system protects the wood in three ways:

  • It protects the wood from harmful ultra-violet rays which can cause graying and coursing of the wood.
  • It protects the wood from water ingress, and being microporous allows excess moisture to escape.
  • It is flexible and it can therefore expand and contract naturally with the timber
