Heat Retention uPVC Windows

One of the most impressive benefits of our uPVC flush sash windows is their energy efficiency. Achieving a Window Energy Rating as high as A++ if triple glazed, their heat retention is truly outstanding. No matter what the unpredictable British weather is doing, you’ll enjoy a home that is comfortable, cosy and warm throughout the year.

Because they’re built from uPVC, a material that can be cleaned with absolute ease, keeping them looking their best is no problem at all either. This will let your free time live up to its name. It’s difficult to go wrong when opting to have uPVC flush casement windows fitted to your home.

Long Lasting Home Renovations

uPVC has become such a popular material in the home renovation market for many reasons. However, one of the standout benefits is it durability and lifespan. If maintained correctly, many quality uPVC windows can continue to perform for around 35 years before showing natural signs of wear and tear.

By using Profile22 frameworks courtesy of our sister company, Emplas, we can provide your home with just that. The uPVC flush casement windows we manufacture and install are as durable as it comes, and they should only ever need occasional upkeep to maintain the factory fresh standard.

Customisable uPVC Flush Casement Windows

At T&K, we believe in allowing local homeowners to have full control over the customisation of their bespoke uPVC flush casement windows. From a range of standard and woodgrain colours to hardware and handles, we have everything you could want to choose from. You never need to compromise by choosing T&K.

You can renovate an older property, improving its overall thermal efficiency and security, without compromising on period charm. With our range of woodgrains and authentic hardware, your home will maintain the heritage aesthetic that makes older properties across the Northamptonshire region so desirable.

uPVC Flush Casement Windows Rushden

Double or Triple Glazed Units

As with our standard casement frames, our uPVC flush casement windows can be fitted with double or triple glazed glass units.


Slimline, Stylish uPVC

Sleek and slim Profile22 uPVC, manufactured by Emplas, is used as standard with the uPVC flush casement windows we install.


Versatile Visuals

Despite authentically replicating traditional timber windows, uPVC flush casement windows can bring their truly stunning design to contemporary homes too.


Warmer Homes

The flush sash uPVC framework is internally chambered as standard. This greatly improves thermal retention and the overall energy performance, keeping a cosy and toasty home all year long.


Weathertight Seals

Between the framework and glazing, we install weathertight seals. They prevent the ingress of draughts, rain or snow, no matter how extreme, keeping you safe and protected.


Flush Fitting Design

uPVC flush casement windows, as their name suggests, are manufactured with a fully flush fitting frame akin to timber joinery.

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!
