The Ultimate in Thermal Efficiency

Triple Glazing

Utilising three panes of glass rather than two, triple glazing exceeds even the best performing double glazed Insulating Glass Units. For a home environment that’s as warm, quiet and comfortable as can be, it’s the perfect solution, especially for Wellingborough & Northamptonshire homes near noisy areas and busy roads.

How does triple glazing reduce condensation on windows?

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 in the air. However, because double and triple glazing is 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.

Can triple glazing be used for conservatories?

Yes, it can. Although conservatories are double glazed as standard, triple glazing can be highly effective when fitted to a conservatory. This is because it makes use of special coatings and it features an extra pane of glass over double, which reduces the risk of overheating during the summer. However, Planitherm Comfort Plus glass, which also has a special reflective layer, can lower the risk of a conservatory overheating too.

Should you choose triple glazing over double?

This will depend on your individual requirements. For most homeowners, high-quality double glazing will keep your home warm, comfortable, quiet and secure. Triple glazing does offer enhanced performance in each of these areas, although it is more expensive. We can advise on the best solution for your home.

Why Choose T&K for Triple Glazing?

In comparison to double glazing, our innovative triple glazing utilises a third pane of glass. Each of the three panes encompass a section that is filled with argon-gas. This state-of-the-art specification is able to break up the currents of airflow, stopping the heat from escaping out of your home and eliminating any draughts from entering.

It can achieve extremely low U-values of 0.8 W/m2K and exceeds the current government guidelines for energy efficiency, saving you money on your energy bills and improving the environmental footprint of your property. The glass we use for our triple glazed products comes from leading glass specialists, Planitherm. This glass has a special reflective coating which actively reflects the heat, for an optimum interior temperature 365 days of the year.

Double Glazing Reviews T&K


Happy Customers

We were more than happy with all aspects of our conservatory installation, right from Shaun the salesman to the guys on the final visit. All the work went through like clockwork, and we were very happy with the end result. Everyone was so helpful and friendly.
Keith Green
The only time we did not use T&K (it was for two windows and one door) we were so disappointed in the products, we had them taken out and replaced by T&K. All our windows and doors have now been done twice by T&K, and we would never even look at anyone else.
Elizabeth Pridmore
We have used T&K for a new door and complete window installation. From the survey stage, receiving a quotation and final installation, the processes were all straight forward and of course we are more than pleased with the quality of the product and just as important the workmanship and politeness of the fitters. Would not hesitate to recommend T&K to family and friends.
Paul Curtis
My wife and I had windows installed some 15 years ago from T&K and they look as good today as when they were first installed, so much so that we recently had our front, back and two French doors installed. We could not be happier with the results.
Richard Simmons
The T&K team were amazing from start to finish. Professional and punctual from the moment of engagement, quotation, surveying, installation and post-installation service. Extremely friendly and high quality team and our windows and doors were definitely worth the investment. Thanks for your efforts. We wouldn’t hesitate to recommend T&K!
Rachel Phillips
I have used T&K on three separate properties now and they have been great. Cost and product as well as installation as promised. Better still your energy cost nose dive in the winter. Highly recommend!
Philippa Sharp
I am so pleased with our recent installation from T&K that I felt compelled to leave this review. Shaun was respectful and patient in dealing with our request and everything that he promised T&K delivered. We received quotes from four other companies, and I am so happy we chose to go with T&K.
Paul-David Symeou
T&K installed a new door for us the whole service has been outstanding from the visit to the showroom to the day of the installation. All members of the team outstanding could not have asked for more. Highly recommend this company.
Steve Raher
