Why choose replacement windows from T&K home improvements?

Here are just some of the reasons why you should choose to get your new double or triple glazed windows fitted by T&K.

Windows that come in your choice of finish

It's essential to have plenty of choices when choosing new windows because every home and every homeowner is different. That’s why we offer a plethora of styles, colours and finishing elements for a unique design for each and every project that we work on.

Depending on the window material that you opt for, there are a varying number of colour options. We also offer wood effect finishes which are ideal if you’re looking to retain the traditional charm of your property or add a touch of character. Modern pebble grey window frames, claystone and sage smooth are just some of the popular colour options that we fit. You could even choose to incorporate dual colour options so that the outer and inner frame are different colours.

We offer a large collection of window furniture pieces, ranging from sleek modern bars to classic monkey tail handles. They’re available in a number of styles to add the perfect finishing touches to your new windows. Decorative glass is also available in an array of patterns to add a bespoke aesthetic to any window.

Windows that are thermally efficient

Thermally efficient windows allow you to stay warm inside of your home whilst saving money on your energy bills, meaning the cost of windows extends beyond the point of purchase. We source only the highest-quality materials, which is why our windows are able to achieve A+ energy ratings, the very best available on the WER (Window Energy Rating) scale.

We use a number of advanced features to maximise the energy efficiency of our replacement windows, including weather seals, innovative glazing and warm edge spacer bars. Depending on the window style, you could choose between double or triple glazing for your new windows which can achieve U-values as low as 0.8. They have either two or three panes of glass that encompass an argon-gas filled chamber to keep the heat inside and stop the draughts from entering your home. With energy wastage minimised, your home’s carbon footprint will be drastically improved.

Windows that will keep the external noises outside

If you currently experience the outdoor noises are disrupting your peace and quiet inside, it’s a sign that your windows have become tired and aren’t performing as they should. With our high-performance windows, you’ll instantly notice that your home is much quieter so you can relax in a comfortable environment.

All of the features that enhance the thermal capabilities of our windows also help with their noise reduction performances. This includes the multi-layered frames, warm edge spacer bars and high-quality glazing panes. Tightly-fitted by our expert installers, with new windows you’ll be able to enjoy a better standard of living.

Windows that keep you safe

Although break-ins are very uncommon, when they occur, the effects can be devastating. That’s why we’re proud to work with both Secured by Design and PAS24. These are two British-Police-backed initiatives which equip, test and certify installers and designers who to confirm the protection of home improvement products.

All of our replacement windows include advanced security locks and hardware that vary with each style. This includes multi-point locks, shootbolt locks and sash window locks. They’re rigorously tested to strict security standards to give you peace of mind that your family are safe and secure from forced entry. If you’re looking for even further protection, we can incorporate additional security elements to your custom-designed windows.

Windows that last a long time

Over long periods of time, weather exposure can degrade the performance of windows. The rate of degradation is influenced by a system’s weather-resistant features, with poor-quality windows needing to be replaced much quicker than advanced systems. With T&K, you can be sure that your new windows will last for many years to come, keeping your home protected.

Our replacement windows have been tested to extreme weathers, including harsh winds, heavy snow and stormy conditions. And time after time, they’ve proven an exceptional ability to stay completely intact. This is because of a range of stormproof elements we incorporate into our range of windows, including deeper-than-average drainage channels and 10mm weather sealings. We finish our window frames in a protective coating which not only stops the colour from fading, but it protects the materials from absorbing moisture, warping or splitting. So, no matter the conditions, they’ll continue to perform and look like new.

Windows that can be fitted with double or triple glazing

The choice between double or triple glazing for new windows is completely dependent on specific requirements, but both of which will improve thermal performances and reduce noise pollution. Here’s an overview of the benefits of each, but for individual guidance, get in touch with our team who can advise on the best option for you.

Double glazing is fabricated using two panes of glass which surround a chamber that is filled argon gas and sealed with a high-performance warm edge spacer bar. Triple glazing includes an extra pane of glass and has two argon-gas filled chambers and can achieve U-values of 0.8 W/m2K.

Double glazed windows are the most popular choice with UK homeowners because of its superior thermal performances and ability to achieve A+ energy ratings. With double glazed windows, you’ll be able to save money on your energy bills. Triple glazed windows stemmed from Scandinavian climates, and as they are 5 times more energy-efficient than a standard window, their thermal performances are unparalleled. They’re ideal for homes that are exposed to harsh weather climates or near airports and main roads as the additional pane of glass improves their nose reduction abilities.
