Market Leading Sliding Sash Windows

We understand how important it is to keep your heritage properties period charm when having new double glazing installed. This is why we source our sliding sash windows from market-leading manufacturers such as Kommerling. They take pride in crafting double glazing products that excel in all areas of performance.

Their sliding sash windows slide by running in the frames internal track, instead of swerving inside or outside like a conventional window. Despite the frames seemingly taking up more space, there is still plenty of room to fit modern-day hardware inside these traditional style uPVC sash windows.

Each sliding sash window we install has a multi-chambered profile, which works to trap hot pockets of air throughout the windows frame. This sophisticated design then helps boost your homes heat retention, trapping any warm air that your home naturally generates.

Not only this, but the layered profile also prevents cold draughts from entering your property too. Over time, this can reduce the need to use your central heating. Helping you not only reduce your carbon footprint, but also cut the cost of your energy bills.

Low Maintenance Sliding Sash Windows

Unlike traditional wooden profiles, our sliding sash windows are exceptionally low maintenance. Homeowners won’t need to worry about time-consuming repainting or varnishing with our uPVC sliding sash window frames. Each frame has an in-built weather-tight seal, which works to create a protective barrier between your home and any harsh weather conditions.

Thanks to this advanced feature, homeowners won’t have to worry about their new sliding sash windows warping, splitting or rotting over time. uPVC is a naturally hardwearing material which continues to perform highly, even after years of exposure to the outside world.

Our uPVC sash windows are also exceptionally simple to clean. The easy to operate mechanisms mean that you can get rid of any dirt or debris that may build up over time. To keep your new installation clean, simply wipe down your sliding sash windows with a damp cloth from time to time. Enjoy a low maintenance home improvement system when choosing our sliding sash windows.

Enhanced Security And Thermal Performance

With traditional style frames, they can be prone to damp and rot, which causes them to weaken over time. This can create a security issue if left unchecked, leaving your window vulnerable to potential break-ins.

With uPVC sliding sash windows, homeowners won’t have to worry about their window weakening over long periods of time. uPVC is a durable material that can withstand sudden impacts and are harder for potential intruders to target when compared to wooden frames.

As well as this, double glazing works in tandem with your uPVC sliding sash window to add an extra layer of security to your home. Double glazing is naturally much thicker than single glazing, making it harder to target, while being much harder to shatter. Rest easy knowing your Milton Keynes home is protected with our high security sliding sash windows.

Customisable Designs

We want to offer customers the option to design sliding sash windows that perfectly suit their Milton Keynes home. This is why we’re proud to offer a diverse range of colour options, finishes and customisable hardware for homeowners to choose from.

With their typically traditional design, sliding sash windows are perfect customers with heritage style properties. When choosing from our outstanding collection, customers have the option of choosing a woodgrain finish. Woodgrain finishes perfectly replicate the look of a traditional timber profile, without any of the downfalls of real wood. This allows Milton Keynes homeowners to enjoy the features of a modern-day window, while still keeping their properties heritage charm.

For those with more contemporary style homes, we offer a number of colour options to suit the sleek appearance of your property. Browse our colour design options, such as classic uPVC white, plain and metallic colours.

What Do Our Customers Say?

Excellent and prompt service from Infinite Windows & Doors when we opted to use them to provide our bifold doors. The builder who is building our extension failed to sort them through his “usual” window company so we cast out on our own and found Infinite. I’m very glad we did. The doors arrived earlier than expected, and were fitted in the course of an afternoon. They look fabulous and will look even better when the rest of the extension build is completed!

S. Thomas

Amazing knowledge from the salesperson, great clarity of documentation, customer service, installation and quality of products. Highly recommend. So refreshing to deal with a professional, approachable Company who practice integrity.
