Maximum Durability & Lifespan

Aluminium casement windows excel in their longevity and consistent performance levels. These are two of the primary reasons for the surge in the popularity of aluminium windows. They can comfortably perform for several decades before beginning to show signs of wear and tear.

Over the duration of this lifespan, you’ll only need to undertake occasional maintenance to ensure your windows look their best. An occasional wipe down on the aluminium casement windows fitted to your Northamptonshire home is all that is required. You can spend more time enjoying your days off work and doing activities you prefer.

Toasty Homes with Aluminium Casement Windows

In addition to many other qualities, a big benefit of these windows is their thermal efficiency. Aluminium casement windows are famed for their ability to trap heat within the home, thanks to the blend of double or triple glazing and the thermally broken, internally chambered profile.

Depending on which casement system you choose from our extensive range, you can comfortably achieve U-values of just 1.2W/m2K. These equal up to A Window Energy Ratings, among the best you can achieve with aluminium casement windows. Never worry about fluctuating temperatures when you choose our aluminium windows, keeping you toasty and comfortable.

Bespoke Slimline Aluminium Windows

Another benefit of choosing T&K is our bespoke, made to measure service. No two homes near to us in Wellingborough are the same, so why should their aluminium casement windows be? We prefer to supply and install tailor made windows that are unique to the individual qualities of your property.

From a range of powder coated, long lasting colour finishes to both traditional and modern furniture, we have it all. We can cater to any taste or budget, with a whole portfolio of aluminium casement window profiles for you to choose from.

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!
