Aluprof has expanded its product portfolio with the launch of the MB-79N CSF outward-opening slimline window system, designed specifically for the UK and Ireland. Combining thermal efficiency, contemporary aesthetics and market-first innovations, the system sets a new standard for fabricators, architects and developers alike.

Slimline Design, Strong Thermal Performance.

At the heart of the MB-79N CSF system is a three-chamber profile with thermal break, delivering excellent insulation while maintaining a refined, slimline appearance. The system supports a wide range of window types—fixed, side-hinged, and top-hinged outward-opening units—and is available in two design options:

• Flush version – a sleek, modern profile with sash and frame aligned on the outer face.
• Non-flush version – a design inspired by traditional casement styles, offering added architectural character.

Versatility Across Building Types.

Engineered for both residential and commercial applications, the system is available in two thermal insulation variants:

• MB-79N CSF ST – standard insulation performance for broad use.
• MB-79N CSF SI – enhanced with additional insulating inserts for maximum energy efficiency.

This flexibility ensures compliance with the UK’s stringent energy regulations while offering customised solutions tailored to project requirements.

Market-First Hybrid Hinge Innovation.

A highlight of the MB-79N CSF system is Aluprof’s innovative hybrid hinge—the first of its kind on the market. Designed for side-hinged variants, it supports weights of up to 80 kg (176 lbs), enabling the fabrication of larger, more durable outward-opening windows without compromising on security or ease of use.

Benefits Across the Value Chain:

• For Fabricators: Streamlined assembly, multiple configurations, and the competitive edge of the hybrid hinge.
• For Architects: Slimline profiles, flexible sash options, extensive finishes, and compliance with energy regulations.
• For Developers: Reduced energy costs, enhanced comfort and security, and durable anodised or powder-coated finishes.

Designed for the Future.

With the MB-79N CSF, Aluprof is offering more than a window system—it is providing a forward-looking solution that balances aesthetics, performance and sustainability. By combining market-specific design with cutting-edge engineering, the company reinforces its position as a leader in high-performance architectural aluminium systems.
