Consisting of two panes of glass that are separated by a small space filled with Argon or Krypton gas, double glazing is designed to improve your home’s performance in a number of ways. T&K’s selection of windows are fitted with it as standard, as are many of our doors.
Get a free quoteHere at T&K, we use two panes of market-leading Planitherm glass for our double glazing. Planitherm Glass features a special coating that reflects heat back into your home. By combining it with the low thermal conductivity of Argon, our double glazing is amazing at retaining heat.
The use of two panes over one ensures double glazing is far more difficult to break than single glazing too. This means your home will have excellent protection against potential intrusions. It’ll also lower the risk of condensation build-up.
With double glazing from T&K, security, energy efficiency and noise reduction are assured, allowing you to enjoy your home in total comfort. However, as installers of the full Planitherm glass range, we’re able to offer glass options that provide additional enhancements to your home.
If opting for Planitherm Comfort or Comfort Plus glass, for example, you can enjoy better security, reduce the amount of noise making its way through the glazing and protect your furniture against UV rays. With Comfort Plus glass, you can also negate the effects of overheating caused by extensive sun exposure. For this reason, it’s an excellent choice for conservatories.

When it comes to choosing your windows, the glass really does make a difference. Glass typically makes up 70% of a window and controls not just energy efficiency, but also the flow of natural light and the level of security. Find out more about the role of glass by viewing the video.
As long as the framing is in good condition, T&K can replace your current double glazing instead of fitting a whole new window.
Our double glazed windows can achieve the highest Window Energy Ratings (WERs).
Our Planitherm Comfort and Comfort Plus Glass has been specially reinforced with a special layer, so it’s harder to break.
Double glazing is suitable for fitting on doors, windows & conservatories.

In order enjoy a warmer, quieter and more secure home, why not consider triple glazing instead?
Condensation is only able to form on surfaces that are cooler than the surrounding air. There must also be a high content of water vapour present in the air.
However, because double and triple glazing are better at reducing heat loss from a room than single glazing, the inner pane of a double or triple glazed window will have a higher surface temperature than a single pane window.
As a result of the warmer glass surface, warm, moist air that is present in the room is less likely to turn into condensation when it meets the surface of the window.
Find out moreWindows are one of the main sources of heat loss in your home, especially windows that are old, single glazed or both. However, T&K’s quality double glazing possesses excellent heat-retaining qualities so more heat is kept inside the home, leading to lower energy bills.
The Energy Savings Trust estimates that by replacing the windows on an entirely single glazed property with A+ rated double glazing, you can save £110 a year on your energy costs.
