Classic+ by Westcoast Windows: Composite Windows Designed in Sweden

In the demanding climate of Sweden’s west coast, windows are not simply a finishing touch – they are essential protection against the elements. That’s where Westcoast Windows began.

Manufactured in Trollhättan, Sweden, Westcoast Windows has spent decades refining high-performance composite windows engineered for some of Scandinavia’s harshest weather conditions. The result is the new Classic+ series – energy-efficient composite windows, designed to deliver exceptional comfort, durability, and long-term performance for modern homes in the UK.

Built for Harsh Nordic Conditions

The Scandinavian climate demands more from a window. Freezing coastal winds, driving rain, and extreme temperature changes have shaped every aspect of the Classic+ design.

Unlike many aluminium-clad windows on the market, the aluminium in Classic+ is not simply decorative – it forms a structural part of the window itself. Combined with dense, slow-grown knot-free pine internally, the result is a window that delivers outstanding strength externally while maintaining the warmth and character of timber indoors.

This tightly engineered construction creates one of the most airtight windows available today, helping homeowners:

• Reduce heat loss
• Lower energy bills
• Improve comfort year-round
• Protect against draughts and moisture
• Minimise external noise

With U-values below 0.90, Classic+ sets a new benchmark for thermal efficiency.

Designed for Modern Living

Classic+ is an evolution of Westcoast’s already proven construction system. Every detail has been refined to improve performance, aesthetics, and longevity.

Slimmer frames and sashes maximise daylight, allowing more natural light into your home while creating cleaner sight-lines and a more contemporary appearance. Mitred aluminium corners give the exterior a sharper, more refined finish, while a discreet brush seal helps protect hardware and reduce water ingress and dirt build-up over time.

The deeper sash design accommodates a 48mm glazing unit, improving insulation performance while also allowing for larger window sizes and more ambitious glazing designs.

Bespoke Windows Made to Measure

Every home is different, which is why every Westcoast window is manufactured to order.

Classic+ windows are available in bespoke sizes at no extra cost, ensuring a perfect fit for renovations, replacement projects, self-builds, and architectural homes alike.

Homeowners and architects can also choose from a wide range of customisation options, including:

• Standard and bespoke colour finishes
• Fixed or opening window designs
• Traditional or contemporary styling
• Mullions and glazing bars
• High-performance glazing upgrades
• Sound reduction glass
• Solar control glass
• Fire-rated glazing options

The result is a completely tailored solution that balances performance with personal style.

Opening Styles to Suit Every Home

The Classic+ range offers flexibility for both traditional and modern properties, with a choice of practical and elegant opening styles.

Fixed Windows

Ideal for maximising daylight and uninterrupted views, fixed windows provide exceptional thermal performance with a clean architectural appearance.

Side-Hung Windows

A timeless outward-opening option, side-hung windows offer excellent ventilation and suit both contemporary and traditional homes.

Tilt-and-Turn Windows

Perfect for modern living, tilt-and-turn windows provide versatile ventilation and easy cleaning from inside the home, making them especially practical for upper floors.

Patio and Sliding Doors

The Classic+ range also includes patio and terrace doors, and sliding doors, all designed with the same focus on airtightness, durability, and Scandinavian design principles.

Minimal Maintenance, Maximum Longevity

Westcoast Windows are built for decades of performance with minimal upkeep.

The powder-coated aluminium exterior is highly resistant to UV exposure, dirt, and harsh weather conditions, removing the need for regular repainting. Integrated drainage channels help eliminate moisture build-up, while tightly sealed joints prevent water penetration and reduce the risk of rot.

Internally, knot-free pine creates a smooth, furniture-grade finish that remains attractive over time without yellowing or knot bleed-through.

Three coats of environmentally responsible water-based paint provide an exceptionally durable finish with extremely low VOC emissions.

Naturally Sustainable

Sustainability is built into every stage of Westcoast’s manufacturing process.

All windows are produced in Westcoast’s own Swedish factory using responsibly sourced materials and energy-efficient production methods. The company holds full PEFC certification, ensuring complete timber traceability from sustainably managed forests.

Additional environmental initiatives include:

• Water-based internal paints with very low solvent content
• Recycled and hydropower-produced “green aluminium”
• Made-to-order manufacturing to reduce waste
• Reuse of surplus timber in pallet production
• Environmentally responsible logistics partnerships

The philosophy is simple: create windows designed to last for decades while minimising environmental impact.

Expert Support From Start to Finish

Choosing new windows is a significant investment, and Westcoast Windows believes expert guidance should be part of the experience.

With over 30 years of experience developing products for Sweden’s toughest climates, the team supports homeowners, architects, and contractors throughout the entire process – from specification and design through to delivery.

Windows are shipped directly from the factory in Sweden to sites across the UK, coordinated carefully to suit each project schedule.

A Window Designed for Life

Classic+ is more than a window system. It is the result of decades spent refining a product capable of withstanding some of the world’s harshest weather while delivering exceptional comfort, efficiency, and design.

Combining the strength of aluminium with the warmth of timber, Classic+ offers homeowners a future-proof solution built for modern living – engineered in Sweden and designed to perform beautifully for decades to come.
