Flush Sash Windows Thrapston

At I Want Windows, we ensure that all our quality flush sash windows have the best quality for your Thrapston home. The flush sash window design has been admired across the country for many centuries; aside from other uPVC windows, these models sit flush within the frame creating clean sightlines that you can enjoy for many years to come.

Although these windows are inspired by traditional design, our flush sash windows offer all the added benefits associated with modern uPVC. With increased levels of weatherproofing, security, thermal efficiency, and no high maintenance upkeeps, our valued customers never have to worry about spending time maintaining these windows.

We are proud to install market leading profiles for our flush sash windows, which means that you can expect the highest window quality as a standard feature in our windows. If you are looking to improve your Thrapston property, get in touch with I Want Windows today!

The Perfect Window Upgrade

All of our flush sash windows provide the perfect fit for any property. Even though we take inspiration from traditional timber window designs, our windows can also fit into new build homes! In older and more traditional Thrapston properties, your new sliding sash window will look and retain the appearance and character of your current design, all whilst carrying modern benefits. In contrast, new builds can take advantage of the uPVC to add character and personality – to give a fresh aesthetic to your home.

We are aware that every Thrapston home is unique so that we can tailor your flush sash windows to your needs and requirements. With our bespoke options, you can have the creative freedom to create a window with various colours and woodgrain effects. We can match these decisions to your existing double glazing products without hassle or stress. If that wasn’t enough, the glass and handles can be chosen and selected by you – get your bespoke flush sash window that matches your property by getting in touch with a friendly member of our I Want Windows team.

Lower Energy Bills

With multi chambered profiles, your new flush sash windows will help your Thrapston home reduce your energy bills. The uPVC frame works alongside the glazing panes to trap pockets of warm air within your property. Even in the coldest of months, these windows will help to create natural warmth for a comfortable home.

Your windows can rely less on your central heating by retaining heat easier. This can reduce your energy bills and save you more money over the year! As less energy is being consumed, your property’s carbon footprint will shrink, too; what more could you want from your brand new flush sash windows?

Secure Peace of Mind

The safety and security of your Thrapston property is a situation that we take very seriously. The features of our flush sash windows are made to protect your home against any burglary methods or modern techniques. With a multi chambered profile, the uPVC frame provides a huge amount of rigidity and strength (which, when working alongside the panes of glazing and locks, creates a high level of protection across the whole window).

Additionally, we fit multipoint locking on the window design as a standard feature which eliminates any possibility of weak points that potential intruders could have exploited. You can have peace of mind that your Thrapston home is secure against any modern methods of break-ins.

Not just for burglaries, our flush sash windows also prevent any harsh weather conditions from seeping in; they will keep out cold draughts and dampness to keep your home undisrupted throughout the year.

Low Maintenance Build

As a Thrapston homeowner, you can expect to invest in a window that truly understands every element of potential hazards, intruders and weather conditions. Unlike wooden windows, which are prone to replacements, you never have to have high maintenance stresses with your new uPVC profile. The frame is created using the highest quality materials and won’t warp, rot, twist, flake or bow after exposure to the unpredictable British weather.

With our bespoke options, the colour and finish will be embedded into the frame, which removes the need for you to buy paint to recoat the window. The only thing you need to worry about is giving the frame an occasional wipe down with a damp cloth to retain the fresh and brand new aesthetic appearance. That’s it!
