Comfortably Warm uPVC French Casement Windows

One of the key reasons for investing in new double glazing is for energy efficiency purposes. For that reason, it was critical that we manufactured, supplied and installed thermally retentive uPVC French casement windows. The systems we offer can attain WER ratings of A+, and U-values as low as 0.9W/m2K.

By renovating your house fully with T&K double or triple glazed windows, you could drastically improve the overall energy efficiency of the property. Cutting out fluctuating temperatures within the home, you’ll be left feeling cosy and warm with our uPVC French casement windows.

In-House Manufacturing

T&K are unique in that we are part of the larger Emplas group. Emplas, of course, are one of the country’s leading manufacturers of uPVC French casement windows, with many styles and designs. By working so closely with them, we are effectively manufacturing your new double glazing in-house.

Not only does this allow for greater customisation for you, but it enables us to provide a greater standard of quality control. Based in Wellingborough, no set of uPVC French casement windows will leave our factory unless they are of the highest standard. You never need to compromise or settle for less.

Low Maintenance uPVC French Casement Windows

Among its many benefits, uPVC is an excellently low maintenance material. It doesn’t require the same level of upkeep as other, more outdated materials do. In fact, our uPVC French casement windows only require an occasional wipe down to look their best.

You’ll need to ensure that the moving components are kept free of dust and debris, but the profile itself should never require regular attention. Your new uPVC French casement windows should never need repainting or refinishing, as they won’t fade through UV exposure. All in all, these windows are a fit and forget solution, leaving you with more free time to enjoy your home.

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
Everyone from the initial sales consultant Steve, to the surveyor, builders, plumbers, electrician, planners and installers were exceptionally professional. I would definitely recommend T&K home improvements to family and friends.
Jonathan Lingard
Have used T&K for Windows etc on three properties. Delighted with quality, installation and after sales service. Have just ordered a conservatory from them!
