Consisting of two panes of glass that are separated by a small space filled with Argon or Krypton gas, the advanced design of double glazing will improve both thermal performance and noise reduction, as well as saving you money on your energy bills. Our selection of windows are fitted with it as standard, as are many of our doors.
Get a free quoteDouble glazing uses two advanced panes of glass which surround an argon-gas filled chamber, making it able to break up currents of airflow, stopping the cold elements from entering your home and the warmth from escaping. This improves the thermal performance of a window and can achieve U-values of 1.2 w/m2K. We use market-leading Planitherm glass for our double glazing products to achieve A+ energy ratings. Planitherm Glass features a special coating that reflects heat back into your home, minimising energy wastage and keeping your rooms at a comfortable temperature. It also stops the draughts from entering your rooms and lowers the risk of condensation building up, for a long-lasting glazing solution. The same features which enhance the energy efficiency abilities also help with noise reduction, as external noises will be unable to enter your rooms, so you can relax in total peace and quiet.
As installers of the full Planitherm glass range, we’re able to offer two glass options. Both Planitherm Comfort and Comfort Plus glass provides the thermal, security and noise reduction benefits you’d expect of high-performance glazing. With Comfort Plus glass, you can also negate the effects of overheating caused by extensive sun exposure and protect furniture from UV rays. For this reason, it’s an excellent choice for conservatories where large panes of glass are used.

When it comes to choosing your windows, you should be sure that they are fitted with technically advanced glazing to maximise their benefits and longevity. All of our window styles and materials come with double glazing as standard for total peace of mind in their performance.
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) of A+, reducing your home's carbon footprint.
Our Planitherm Comfort and Comfort Plus Glass has been reinforced with a special layer, so it’s harder to break.
Double glazing is suitable for windows, doors & 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, our 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.
Learn more about reducing your heating billsNot only can we fit double glazed windows with trickle vents but they are actually a legal requirement when replacing windows that have already been fitted with them. Trickle vents are a great way to provide your home with background ventilation.
