Joy & Peter Martindale

“I wanted to write to you and your team for the swift supply and installation of new double glazing windows for the entire flat. I’m very pleased with the appearance; they are, as you promised, ‘A rated products’ both visually and, I’m sure, performance wise.”

Richard Mutton

“Just a short note of thanks, for the efficient installation of porch and windows earlier this week. I cannot heap enough praise on John and his brother for the skilled work they undertook. Nothing was too much trouble, their craftmanship was superb, and their cleaning skills legendary. All rolled in with a great sense of humour.”

Windows FAQ

Click on some of our frequently asked questions below to find out more information on replacement windows.

Providing a quotation for replacement double glazing takes into account a lot of variables and cannot always be done 'off the cuff'.
These factors can include (but are not limited to):
  • The material and size of the windows required.
  • How many opening window sashes needed.
  • The type of glass used (double / triple / obscure / laminated / acoustic).
  • The number of sections the window is split into.
  • ...and many other factors that can also greatly influence the price of the project.
With this in mind, there are plenty of options that can be changed or tweaked to ensure the cost of the job is tailored to fit your budget.

People will often colloquially refer to replacement windows as "double glazing" so it is not too far fetched to be a little confused as to what the term really means.
Essentially, the difference between double and triple glazing is quite simple, it just refers to how many panes of glass are being used in the glazed unit.
Double glazing is two panes of glass, Triple glazing is three panes of glass.

Do I need double or triple glazing you may be thinking?
Replacing your old window frames for new will often drastically upscale and improve the energy efficiency within your home. Reducing draughts and providing greater thermal efficiency with our A-rated glass units (as standard). These units are coated with an invisible film on the inside pane which reflects internal heat energy - sending it back inside the property. Instead of letting it leak through the glass!

So with this in mind, the upgrade provided by double glazing is often enough to feel a noticeable difference after you have your windows replaced.
However, if ultra-performance is your goal then choosing triple glazing will provide that extra boost you are looking for. Keeping your home warmer for less, by ultimately reducing the cost it takes to heat your household.
All of our windows carry an A+ energy rating, ensuring a very high level of energy efficiency.

What are the energy ratings and what requirements are there for new windows?
Energy ratings are a simple and easy way for you to quickly identify and compare how energy efficient a replacement window system is.
There are several energy rating schemes, the most common is operated by the British Fenestration Rating Council, which we use to allocate our energy rating.
The latest Building Regulations require that all newly installed windows must meet the requirements of a C rating. The exception to this is windows fitted into listed buildings.

For more information, please feel free to speak to a member of our team on 01895 622207.
Installing a window with a higher standard of energy efficiency allows you to save more money on your heating and energy bills. This is because it will cost less money to maintain the temperature of your home.

The way this works is twofold:
Firstly, the latest technology in the manufacturing process ensures that our window frames are made to be draught proof, weathertight and thermally preservative.
Secondly, we install A-rated energy glass units, which are coated with an invisible film on the inside pane which reflects internal heat energy - sending it back inside the property. Instead of letting it leak through the glass!

With this in mind, replacing your old double glazing can be seen as an investment in your household. As the reduction in your energy bills will pay dividends over time.
If you would like more information, please free to speak to a member of our team on 01895 622207.
All of our windows, whether in uPVC or Aluminium are available in a wide variety of colours, meaning you can tailor your windows to match your design aesthetic.
We can manufacture windows to match any RAL colour swatch, just bear in mind that custom colours do come with a slightly higher price tag.
Picking a conventional colour is the cheaper option, and the available colours for each window can be found near the bottom of each relevant web page.
