Our Materials & Brand Partnerships

We use only the finest materials and partner with industry-leading brands to guarantee longevity, security, and thermal efficiency.

• Schüco Windows: For those seeking the pinnacle of design and engineering. Schüco’s aluminium and uPVC systems offer slim sightlines, exceptional strength, and outstanding weather resistance, perfect for ambitious architectural projects.

• Eurocell Windows: A leading UK manufacturer known for its high-quality, sustainable uPVC systems. Eurocell offers fantastic versatility, a wide range of colours and finishes, and is renowned for its excellent energy efficiency.

Our Window Styles

• Aluminium Windows: Sleek, strong, and incredibly durable. Ideal for creating large, panoramic glazing with minimal frames. Resistant to corrosion and available in a vast spectrum of contemporary colours.

• uPVC Windows: The gold standard for value, security, and low maintenance. Our uPVC windows are designed to last for decades without warping, fading, or rotting.

• Casement Windows: The UK’s most popular style. Our casement windows are engineered for a perfect seal, offering superior ventilation control, weatherproofing, and security.

• Flush Fit Windows: For a truly traditional and elegant look. The sashes sit flush within the frame, replicating the aesthetic of historic timber sash windows but with all the benefits of modern uPVC or aluminium technology.

• uPVC Sash Windows: Enjoy the classic charm of sliding sash windows combined with 21st-century performance. Our uPVC sash windows are draught-free, secure, and far more energy-efficient than their original timber counterparts.

Our Manufacturing Promise:

• Quality Control: By overseeing every stage of production, from cutting the profiles to fitting the glazing and hardware, we maintain stringent quality control that third-party fabricators cannot match.
• Premium Materials: We use only high-grade aluminium profiles from world-renowned brand Schüco and advanced, multi-chambered uPVC from UK leader Eurocell.
• Advanced Technology: Our workshop is equipped with the latest machinery for precision cutting, welding, and finishing, guaranteeing tight seals, perfect alignment, and a flawless aesthetic.
• Bespoke Solutions: We craft windows in any configuration you need, including custom colours, finishes, and hardware choices, ensuring the final product is a perfect reflection of your taste.

Windows Supply: A Style for Every Home

We offer an extensive selection of high-performance windows, combining cutting-edge technology with timeless design. All our windows are supplied with advanced double glazing as standard, delivering outstanding thermal and acoustic insulation. The thermal efficiency of a window is measured by its U-value, where a lower value indicates better insulation. Our windows are designed to achieve exceptionally low U-values, helping you reduce energy consumption. The rate of heat transfer, $Q$, through a window can be described by the formula $Q=U\cdot A\cdot \Delta T$, where $U$ is the U-value, $A$ is the area, and $\Delta T$ is the temperature difference. By minimising $U$, we help you keep your home warmer in winter and cooler in summer.

Aluminium Windows

For a sleek, contemporary aesthetic, nothing surpasses the elegance of aluminium. Partnering with Schüco, we supply premium aluminium windows known for their slim sightlines, exceptional strength, and design flexibility.

• Maximum Natural Light: Ultra-slim frames allow for a larger glass area, flooding your home with light.
• Unmatched Durability: Aluminium is inherently strong and corrosion-resistant, ensuring your windows will not warp, rust, or fade over time.
• Superb Thermal Performance: Modern aluminium windows feature a polyamide thermal break to create a highly insulated frame.

uPVC Windows

Versatile, low-maintenance, and incredibly energy-efficient, our uPVC windows manufactured with Eurocell profiles are a popular choice for any property.

• A-Rated Energy Efficiency: The multi-chambered profile design traps air, creating an insulating barrier that significantly reduces heat loss and lowers your heating bills.
• Low Maintenance: uPVC requires no painting or sealing—just a simple wipe-clean to keep it looking brand new for years.
• Excellent Versatility: Available in a vast range of colours, woodgrain foils, and styles to suit any home.
