Key Features of Our uPVC Casement Windows
Sculptured Profile
For added character, the frame and opening sashes of each uPVC casement window is made using a stunning carving technique creating a traditional sculptured appearance. We use Deceuninck’s 2800 profile for our casement windows, offering high quality, attractive windows no matter the configuration.
Corner Joints
Our standard welding technique creates tightly bonded corners, resulting in a seamless and robust connection. The 45° corner welds undergo thorough cleaning with advanced machinery to achieve a pristine finish on the frame.
Recycled Core Material
The recycled core, made from reclaimed uPVC, help reduce waste and the environmental impact of manufacturing processes. While the outer layer remains made from virgin uPVC to ensure a smooth white finish and optimal performance, the inner core can incorporate recycled content without compromising structural integrity or performance.
Astragal Bars
Astragal bars are fixed onto the surface of the glass and are accompanied by back-to-back spacer bars inside the unit. Historically, astragal bars were used to divide larger panes of glass into smaller sections, which was practical when manufacturing larger sheets of glass was more challenging or expensive. They can be fitted in various layouts, such as horizontal or vertical bars, to complement different architectural styles and preferences.
Multi-point Locking Mechanism
uPVC windows come equipped with a multi-point locking mechanism, providing unparalleled security and peace of mind. This advanced system features multiple locking points that engage simultaneously when the window is closed, distributing the locking force evenly along the frame.
Friction Stay
A friction stay is a key component used in uPVC casement windows to provide smooth, controlled opening and closing. Unlike traditional hinges, friction hinges allow these windows to stay open at various angles without the need for additional support or a mechanical stay.
Trickle Vent
New Building Regs state that trickle vents are required on virtually all glazing elements. The purpose of the vents is to allow airflow even when the window is closed. Our trickle vents are colour-matched to match the chosen finish of our uPVC windows and are available in two different sizes: 2500EA and 5000EA.
Sill Options
Our uPVC windows come with a variety of sill options to meet the functional needs of the window opening.
Choose between: No sill / 95mm / 150mm / 180mm

Glazing Options
Double Glazing
Our casement windows, featuring 28mm double glazing, offer exceptional thermal insulation properties. Each glazed window consists of two glass panes with a sealed pocket of argon gas in between, effectively minimising heat transfer. As standard, our double glazed windows come with an impressive energy rating of ‘A’. This high level of energy performance is achieved without compromising on style or durability, making Quickslide’s uPVC casement windows a smart investment for any homeowner.
Triple Glazing
We also offer an optional upgrade to triple glazing on our casement windows. By incorporating an extra pane of glass and an additional argon gas space between the panes, triple glazing significantly enhances the window’s ability to retain heat. With this advanced glazing option, our windows can achieve U-values as low as 1.0, providing maximum energy efficiency and comfort for any home.
Spacer Bars
Spacer bars are placed around the perimeter of the glass panes to provide essential structural support and maintain consistent spacing between the panes. Choose from our selection of three bar colours to complement your window’s aesthetic and enhance its overall appeal.
Preview finishes
Laminated Glass
You have the option to upgrade your traditional casement windows with laminated glass for enhanced safety while still keeping your windows performing efficiently. A key benefit of laminated glass lies in its safety features. It’s designed to stay together if broken, rather than shattering into lots of sharp pieces.
Obscure Glass
Perfect for privacy-focused areas like bathrooms where clear glazing isn’t ideal, we offer obscure glass options – the most popular being Satin glass, also known as frosted glass. It features a smooth, matt finish that lets in natural light while blocking the view from outside.

Venetian Integral Blinds
Venetian integral blinds provide a stylish and practical solution for casement windows. Integrated seamlessly within the double-glazed unit, these blinds offer homeowners privacy, light control, and enhanced energy efficiency. Available in a variety of 10 different colours to complement your chosen frame finish. Please note that the operational device will always be positioned on the right-hand side (viewed internally).

Weatherproofing
Casement windows are among the most efficient windows available due to the tight seal between the sash and frame. Their airtight seal aids the thermal efficiency of our uPVC windows, stopping the ingress of cold air which helps to keep the internal living spaces nice and cosy. All our modern uPVC windows are made using the latest technology.
Thermal Efficiency
We use the best insulating materials for our plastic windows, ensuring optimal thermal performance. Our uPVC casement windows are available with energy ratings of up to ‘A’. With energy prices soaring, our windows can insulate the home and could help reduce the homeowner’s energy bills.
Security
Security is a top priority at Quickslide, which is why all our uPVC windows come equipped with a reliable multi-point locking mechanism as standard, providing robust protection for your home. For homeowners seeking even greater peace of mind, we offer the option to upgrade to our PAS 24 security package. This comprehensive upgrade includes additional security features, ensuring your windows meet strict industry standards for enhanced resistance to forced entry.
Manufacturing Guarantee
With all casement windows manufactured here in West Yorkshire, there is a manufacturing guarantee of up to ten years as standard, depending on product features and specifications. While all our windows provide outstanding, long term quality, we appreciate that having a decade long guarantee on key components offers peace of mind.

Modern Casement Window Materials
We manufacture our casement windows using high-quality, expertly extruded uPVC for exceptional durability, performance, and style. The 2800 Deceuninck uPVC profile we use is renowned for its sculptured design, offering striking aesthetics that enhance the overall appearance of any home, whether modern or traditional.
Compared to outdated materials like timber, uPVC offers a range of advantages. It’s highly durable, resisting warping, rotting, and weathering, which makes it a long-lasting solution that requires minimal maintenance. You won’t have to worry about frequent painting, sanding, or repairs, as uPVC is designed to retain its appearance for years with just occasional cleaning.
uPVC is also known for its excellent thermal efficiency. The multi-chambered design of the Deceuninck profile helps trap heat inside your home, reducing energy consumption and keeping your living space warm in winter and cool in summer. This can mean lower energy bills and a reduced environmental footprint without compromising on style or comfort.

Will uPVC casement windows reduce the noise levels from outside?
If you are replacing your single glazed windows with new casement windows from Quickslide, the homeowner will likely see a noticeable reduction in noise pollution. With the extra layer of glass found in the double glazed unit, less sound will be able to filter in.
What is a casement window?
Casement windows are recognisable by sashes that are attached to their frame via one or more hinges.
At Quickslide, we have a range of popular uPVC double glazed windows beyond our casement range. The windows for sale via our website include sash windows, French, flush, and more.
Have you supplied windows for new build projects before?
Yes, we have a strong track record of working with developers across the UK. You can view some of our case studies to see how our windows look and perform in new-build homes. We have a team of project specialists who are happy to discuss ongoing supply arrangements for larger or phased developments to suit your build schedule.
Can Quickslide deliver uPVC windows for multi-plot new build developments?
Yes, we regularly supply uPVC casement windows for multi-plot developments. Our production capability, reliable lead times, and new build experience make us an ideal supply partner for residential projects of all sizes. And should you need supply & installation for your developments, we can cater for these requirements too.
Is triple glazing better than double glazing?
Triple glazing can be better than double glazing in certain situations, but it’s not always the right choice for everyone. It offers improved insulation, so it’s great for keeping heat in and noise out – especially useful in very cold climates or noisy areas. However, it’s also more expensive and heavier, which can affect the type of frames you need and how easy the windows are to open. For many UK homes, high-quality double glazing is more than enough to keep things warm and quiet.
