ALUPROF's MB-79N window and door system has been awarded ATG Technical Approval No. 3380, issued by BUtgB-UBAtc, the Belgian organisation responsible for the certification of construction products. This important milestone confirms both the system's high quality and its compliance with the technical requirements and construction practices applicable in Belgium.

The ATG approval officially authorises the MB-79N system for use on the Belgian market, creating new opportunities for growth and business development for ALUPROF's fabricators and partners. It also confirms that the system meets Belgium's stringent technical standards and the expectations of both developers and construction professionals.

A modern and highly versatile solution within the ALUPROF portfolio, the MB-79N combines outstanding performance with exceptional design flexibility. Its wide range of applications makes it equally well suited to residential and commercial projects, delivering durability, aesthetics and energy efficiency to the highest standards.

Securing Belgian ATG approval for the MB-79N also represents a strategic milestone in the ongoing development of ALUPROF's product portfolio. It marks the final step before the company begins the phased withdrawal of systems from the MB-70 family. Under the current roadmap, these products will be discontinued by the end of the year, making way for a new generation of solutions designed to meet today's market expectations.

ATG Approval No. 3380 is the latest certification issued by BUtgB-UBAtc for an ALUPROF solution. ATG approvals have also been granted for the MB-86 window system, MB-77HS lift-and-slide doors, MB-78EI fire-rated doors and the MB-SR50N curtain wall system.
