Alitherm Windows – Features & Benefits

BDC Aluminium is your trusted supplier of premium aluminium fenestration products. With a wide-ranging portfolio designed to meet the needs of builders, architects, and construction professionals alike, we pride ourselves on delivering quality, performance, and style.

You probably don’t need us to explain just how important windows are to a building’s façade. Whether residential, commercial, or public, the external face of any structure sends a clear message to those who pass by or approach it. That first impression matters—and well-designed windows play a crucial role in defining a building’s character, energy efficiency, and overall appeal.

In this article, we’re showcasing one of our most popular aluminium solutions: Alitherm Windows. We’ll guide you through their versatile designs, highlight key features and benefits, and explain why partnering with BDC Aluminium is the smart choice for your next project.

What Are Alitherm Windows?

Our Alitherm Windows—featuring Alitherm Heritage, Alitherm 400, and Alitherm 600—are crafted using profiles from Smart Systems, the UK’s leading supplier of aluminium glazing solutions and bespoke extrusions.

With over 40 years of industry expertise, Smart is renowned for innovation, design precision, and technical excellence. Their systems are trusted across the UK for delivering high performance, reliability, and sleek aesthetics in both residential and commercial settings.

When you choose Alitherm Windows from BDC Aluminium, you’re not just investing in premium aluminium systems—you’re partnering with two names synonymous with quality, consistency, and long-term value.

Thanks to the versatility of our Alitherm range, we have the ideal solution for virtually any construction project. Whether it’s a new build, refurbishment, or a residential or light commercial development, Alitherm Windows deliver the performance you can rely on.

So, what exactly makes them stand out?

Superior Thermal Efficiency

Achieving a low U-value is more important than ever when selecting a window provider, especially in today’s climate of rising energy costs. For energy-conscious construction, you can count on BDC Aluminium to deliver high-performance, thermally efficient solutions.

Each of our Alitherm Windows offers impressively low U-values. Alitherm Heritage, for instance, achieves 1.6 W/m²K—a remarkable performance given its slim sightlines and traditional, period-inspired aesthetic. It’s the ideal choice for preserving the architectural character of listed buildings, heritage homes, and refurbishment projects, where maintaining a period look is just as important as meeting modern efficiency standards.

Alitherm 400 achieves a U-value of 1.4 W/m²K, while Alitherm 600 performs even better, reaching as low as 1.3 W/m²K. This outstanding thermal performance is made possible by Smart’s innovative polyamide thermal break technology, which enhances insulation and supports compliance with the latest energy regulations across a wide range of applications.

Strong, Safe and Durable

Performance only matters if it stands the test of time. That’s why all our Alitherm Windows are constructed from premium-grade aluminium—an inherently strong, low-maintenance, and long-lasting material that far outperforms uPVC or timber when it comes to durability and stability.

Security and compliance are built into every product. Our Alitherm Windows are BSI certified, meaning they meet internationally recognised standards for quality, safety, and operational performance as set by the British Standards Institution. They’re also PAS 24 accredited, confirming they’ve passed rigorous testing against forced entry.

With these credentials behind them, our Alitherm Windows offer peace of mind alongside outstanding longevity and visual appeal.

What is an Internal Screen and How Can It Transform Your Space

Nowadays, the demand for flexible, high-performance partitioning is higher than ever. Internal screens are fast becoming the preferred solution of architects, installers and specifiers for the combination of visual openness and functional benefits they provide.   At BDC Aluminium, we believe that a well-specified internal screen system can completely transform both living and working spaces. Fortunately for you, we have a perfect, flexible system. What is an Internal Screen? An internal screen is a non-load-bearing partition system, designed to divide zones within an open-plan interior. The beauty of our Aluspace internal screening system lies in its ability to preserve the flow of daylight throughout the interior space. Unlike solid walls, internal screens provide spatial definition, partitioning certain spaces into commercial necessities such as meeting rooms, corridors or lounge spaces, without the bulk of a conventional permanent wall. If this is what you’re looking to incorporate into your next project, BDC Aluminium offer the Smart Aluspace System that delivers this effectively. This accommodates fixed screens, plus hinged, pivot and sliding doors. Our internal doors can be installed faster than conventional products, and seamlessly integrate with a property’s existing joinery and glazing systems. The Aesthetic Appeal of Internal Screens Our internal screens have minimal sightlines, sleek profiles and are designed to fit with a contemporary aesthetic that complements modern office, hospitality zones and premium residential interiors. Our finish options provide serious flexibility, ensuring we can tailor each system to your exact project specifications. The AluSpace system supports over 200 RAL colours, along with a choice of textured finishes and foil-coated options, all backed by a 25-year guarantee for long-term durability and peace of mind. Practicality & Maintenance In the commercial and development industry, practical performance is as important as aesthetics. Fortunately, our aluminium internal screens score highly in this department, too. Aluminium is durable and resistant to corrosion, warping and wear in high-traffic commercial or residential environments. Designed for durability and ease of maintenance, their upkeep is minimal and infrequent. Due to their powder-coated finish, the surfaces are easy to clean and require no seasonal maintenance. The modular nature of our aluminium screening systems means much faster site assembly, less disruption and quicker handover compared to traditional stud-walling. Work with BDC Aluminium! The Aluspace internal screening system from Smart and BDC Aluminium encapsulates the needs of developers, installers and specifiers. Design finesse, operational flexibility and robust practicality combine to make more than just dividers. For trade professionals seeking a reliable, high-quality interior solution, we have you covered. At BDC Aluminium, we’re your one-stop shop for aluminium systems, offering expertise, product range, and service you can depend on.
