CASEMENT WINDOWS
Classic design. Modern performance.
Classic Design, Modern Performance
Casement windows are one of the most popular choices for UK homeowners — and it's easy to see why. Hinged at the side and opening outward, they offer a clean, uncluttered look that works equally well on a period cottage or a contemporary extension. Their straightforward design means they're one of the most cost-effective window styles available, without any compromise on quality or performance.
What makes casement windows so enduringly popular is their versatility. Available in uPVC, aluminium and a wide range of colours and finishes, they can be tailored to complement virtually any property. Whether you're after the classic flush casement look for a traditional home or a sleek, slim-framed version for a modern build, there's a configuration to suit. They also accommodate a wide range of glazing options, including double and triple glazed units, making them an excellent choice for homeowners looking to improve thermal efficiency and reduce outside noise.
From a practical standpoint, casement windows are hard to beat. They open fully to allow maximum ventilation, are straightforward to clean, and when fitted with modern multi-point locking systems, offer a strong level of security as standard. Whether you're replacing tired existing windows or specifying for a new build or extension, our casement range delivers the ideal balance of performance, appearance and long-term value.
Why Choose Casement Windows?
Casement windows have stood the test of time for good reason. Practical, versatile and available in a huge range of styles and finishes, they offer something for every homeowner — whether you're after a clean modern look or a more traditional feel.
Customisation
Choose from a wide range of colours, finishes, glazing options and hardware to create casement windows that are tailored precisely to your home and your taste.
Energy Efficiency
Our casement windows are engineered to minimise heat loss, keeping your home warmer for longer and reducing the strain on your heating system — with energy ratings of A and above available.
Security
Every casement window we install comes fitted with modern multi-point locking systems as standard — making them far more resistant to forced entry than older single-point locks.
Low Maintenance
Casement windows require very little upkeep. uPVC and aluminium frames never need painting, sanding or sealing — just an occasional wipe down with warm soapy water is all it takes to keep them looking as good as new for decades.
UPVC Casement Windows
uPVC casement windows have become the go-to choice for homeowners across the UK, and it's not difficult to understand why. The material is incredibly durable, requires virtually no maintenance, and delivers excellent thermal and acoustic performance at a price point that's hard to beat. Unlike timber, uPVC won't rot, warp or need repainting — it simply gets on with the job, year after year.
For those looking to improve their home's energy efficiency without spending a fortune, uPVC casement windows are one of the smartest investments available. Our systems are fully compliant with current building regulations and can be specified with high-performance double or triple glazing to suit your needs.
- Excellent thermal efficiency — lower energy bills
- Strong acoustic performance
- Never needs painting or staining
- Highly weather resistant
- Cost-effective without compromising on quality
Aluminium Casement Windows
If you're after a more premium finish with a distinctly modern edge, aluminium casement windows are the natural choice. Aluminium is considerably stronger than uPVC, which means frames can be made with much slimmer sightlines — letting in more natural light and creating a cleaner, more refined aesthetic. It's the material of choice for contemporary extensions, new builds and anyone who wants their windows to make a statement.
Modern aluminium casement windows are engineered with a thermal break running through the frame, which dramatically improves insulation compared to older aluminium systems. Add in the virtually unlimited colour options through powder coating and you have a window that's as flexible as it is impressive.
- Ultra-slim sightlines for maximum glass area
- Advanced thermal break technology
- Incredibly strong and long lasting
- Over 200 RAL colour options available
- Perfect for modern and contemporary properties
Aluminium Casement Windows
For those who want a more premium, contemporary finish, aluminium casement windows are the standout choice. Significantly stronger than uPVC, aluminium allows for much slimmer frames without losing any structural integrity — meaning more glass, more natural light, and a cleaner, more architectural look that suits modern extensions, new builds and anyone who wants their windows to genuinely enhance the appearance of their home.
Today's aluminium casement windows are a world away from the draughty metal frames of the past. Advanced thermal break technology running through the frame dramatically improves insulation, while the powder-coated finish is available in virtually any colour, making it easy to achieve exactly the look you're after — whether that's a classic white, a bold anthracite grey or a bespoke RAL shade to match your property perfectly.
- Ultra-slim sightlines — more glass, more light
- Advanced thermal break for excellent insulation
- Over 200 RAL colour options available
- Incredibly strong and built to last 30+ years
- Low maintenance — never needs painting
- Suits contemporary and traditional properties
Flush Casement Windows
Flush casement windows have a distinctly elegant appearance that sets them apart from standard casement styles. Rather than the sash sitting proud of the outer frame, the sash sits flush within it — creating a smooth, flat surface on the outside that gives the window a refined, almost timber-like quality. It's a look that works beautifully on period properties, conservation areas and any home where traditional aesthetics matter.
Available in both uPVC and aluminium, flush casements combine classic good looks with modern performance. They meet current building regulations for thermal efficiency and security, and can be specified with a range of heritage-inspired hardware options to complete the traditional aesthetic. If you want the character of a period window without the maintenance headaches of timber, a flush casement is the perfect solution.
- Smooth flush exterior for a refined, traditional look
- Ideal for period properties and conservation areas
- Available in uPVC and aluminium
- Wide range of heritage hardware options
- Fully compliant with current building regulations
- Low maintenance with excellent long-term performance
