Who makes Alitherm windows?

Alitherm windows are manufactured by Smart Systems, a leading UK-based company specializing in high-performance aluminium window and door systems. Established in 1981, Smart Systems is known for its innovation, quality, and extensive product range, catering to both residential and commercial markets. Their Alitherm range is designed to provide exceptional thermal efficiency, durability, and aesthetic versatility.

What is Alitherm 400?

Alitherm 400 is a premium aluminium window and door system developed by Smart Architectural Aluminium. It’s designed to combine sleek modern aesthetics with high energy performance and security — making it a popular choice for both residential and commercial properties.

What is the difference between Alitherm 400 and 600?

The Alitherm 400 and Alitherm 600 systems are both popular aluminium window solutions from Smart Architectural Aluminium, but they’re designed for slightly different applications and styles.


Alitherm 400 is the newer of the two and was developed to meet the latest UK Building Regulations, including Document L for energy efficiency. It’s a versatile system designed for both windows and doors, making it ideal for residential projects that want a consistent, modern aesthetic throughout. It features slim sightlines, excellent thermal performance, and is compatible with both double and triple glazing. With a 70mm frame depth and PAS 24 security compliance, it’s a great choice for homeowners looking for a sleek, high-performing window and door system.


In contrast, Alitherm 600 is a more established product that’s primarily used for top-hung and side-hung windows. While it still offers solid energy efficiency through thermally broken aluminium profiles and meets key performance standards, it has a slightly chunkier profile and a more traditional appearance. The frame depth is slightly shallower at 59.5mm, and it’s generally suited to window-only applications, particularly in properties where a more classic aluminium look is preferred.


In summary, Alitherm 400 is ideal for modern homes and those seeking uniformity across both windows and doors, with improved thermal performance and up-to-date regulatory compliance. Alitherm 600, on the other hand, is best for traditional-style properties or refurbishments where only windows are being replaced and a more classic aesthetic is desired.
