Flush uPVC casement windows are rapidly gaining popularity among homeowners and developers alike. Combining modern efficiency with a classic aesthetic, these windows offer a sleek, flush exterior finish while retaining the timeless appeal of traditional casement windows inside. Whether you're upgrading your existing windows or building a new home, flush casement windows are an excellent choice for enhancing both the look and performance of your property.


Refresh Your Outlook on the World

Windows are a defining feature of your home—they frame your view of the outside world while shaping the character and appearance of your property. Whether you own a stylish new-build, a traditional Victorian terrace, or a chic apartment, choosing the right windows can elevate both the interior and exterior appeal of your home. In short, they're like the glasses of your house—get the right pair, and suddenly, everything looks better.

Flush uPVC casement windows not only enhance the aesthetics of your property but also provide long-lasting protection against the elements, improved energy efficiency, and enhanced security. With versatile designs and a variety of customisation options, you can find the perfect style to suit your home.


What Are Flush Casement uPVC Windows?

Flush casement windows are designed so that the window sash sits perfectly flush with the outer frame when closed, creating a smooth and streamlined appearance. Unlike traditional stormproof windows, which protrude slightly from the frame, flush casement windows provide a clean, contemporary look that suits both modern and period properties. So, if your old windows are sticking out like a sore thumb, it might be time for a change.

Engineered with a 70mm front-to-back profile, these windows can seamlessly replace timber frames while enhancing the overall appearance of your home. The unobtrusive gasket line and slim profile further contribute to clean sightlines and a sleek finish.

Key Benefits of Flush Casement Windows

  1. Sleek and Modern Design

    The flush exterior finish of these windows provides a minimalist look that complements a variety of architectural styles. The slimmer frame maximises the glass area, allowing more natural light into your home and offering a clearer view of the outdoors. It’s like upgrading from a regular TV to a 4K screen—everything just looks sharper.


Customise the look further with stylish accessories like Georgian bars, mock horn sashes, or arch-top inserts to create a unique design that perfectly matches your property.

An extensive choice of woodgrain foils offers a realistic timber-like appearance, while through-colour grey options deliver a stylish, architectural finish.


  1. Exceptional Energy Efficiency

    Flush uPVC casement windows boast outstanding thermal performance. Featuring a multi-chambered profile design and innovative PVC-U thermal inserts, they help lock in heat and minimise energy loss. You’ll be saving on energy bills faster than you can say “double glazing!” With U-values as low as 0.8 and A++ energy ratings, these windows make your home more comfortable while keeping your wallet happy.

  2. Durability and Low Maintenance

    Built to withstand harsh weather conditions, flush uPVC casement windows require minimal upkeep. The incorporation of single steel reinforcement bars adds extra strength, ensuring long-lasting durability. Unlike timber frames, which require frequent painting and sealing, uPVC windows only need the occasional wipe-down. So, if you’re tired of DIY weekends spent on window upkeep, this is your ticket out.


Additionally, the post co-extruded (PCE) gaskets use a specially developed compound and twin-leg profile connection system to achieve exceptional air tightness and weather resistance. This advanced sealing system significantly reduces air leakage, further improving thermal performance.


  1. Enhanced Security

    Modern flush casement windows are designed with security in mind. Reinforced frames, robust locking mechanisms, and the use of single steel reinforcement bars provide excellent protection against potential break-ins. So, you can rest easy knowing your windows aren't the weak link in your home security.


  2. Noise Reduction

    Thanks to the advanced sealing systems and high-quality materials, flush casement windows offer superior noise insulation. This is especially beneficial for properties located near busy roads or in noisy urban environments. It's like having a noise-cancelling feature for your entire house.


Ideal for Both New Builds and Replacements

Flush uPVC casement windows are highly versatile and suitable for various applications. Their 70mm profile allows for easy installation in both new builds and as replacements for existing windows. With features like a patented knock-in bead system, these windows facilitate swift and efficient installation—so you can spend more time enjoying your upgraded home and less time supervising the builders.

The fast and accurate fabrication process ensures these windows are well-suited for time-sensitive projects. Additionally, their clean sightlines and wide range of styles allow homeowners to enhance the aesthetic appeal of their properties without compromising on performance.

Sustainability Matters

Sustainability is a key advantage of flush uPVC casement windows. Many systems feature post-consumer recycled PVC-U in their core, with virgin PVC-U on the visible faces to maintain high-quality aesthetics and performance.
