MB 86N – modern aluminum window system with narrow profiles
The Bertrand MB-86N system represents the next generation of high-performance aluminum windows and doors. Building on the proven success of the MB-86 line, MB-86N features improved profile geometry, upgraded thermal insulation, and optimized production technology.
It offers a modern, minimalist design with slim sightlines and excellent durability, perfectly suited for residential, commercial, and architectural applications requiring both aesthetics and performance.
Key features:
Modern design: Contemporary appearance with narrow, elegant profiles that enhance the look of any building façade.
Improved thermal performance: Redesigned thermal breaks and optimized chamber geometry provide exceptional insulation.
Two-component central gasket: Guarantees superior sealing, minimizing air and water infiltration.
Wide glazing compatibility: Accommodates a broad range of glass thicknesses, including acoustic, solar-control, and safety glazing.
Three-chamber construction: Combines rigidity, strength, and energy efficiency.
Advanced technology: Engineered for faster fabrication and easier installation in modern production environments.
Design versatility: Available in multiple configurations — fixed, turn, tilt-and-turn, and hidden sash (MB-86N US) — as well as door versions and folding systems (MB-86N Fold Line).
Benefits of MB-86N:
Energy efficient: High thermal insulation reduces energy consumption and enhances comfort.
Durable and strong: Robust aluminum profiles allow for large, heavy glazing units.
Flexible design: Supports multiple opening types and configurations for architectural freedom.
Aesthetic minimalism: Narrow sightlines and modern profile geometry suit contemporary projects.
Enhanced manufacturability: Simplified assembly process and compatibility with automated fabrication lines.
Low maintenance: Corrosion-resistant materials and durable finishes ensure long service life.
System variants:
MB-86N ST – Standard version offering an excellent balance of performance and cost.
MB-86N SI – Enhanced thermal insulation for demanding energy-efficient buildings.
MB-86N US – Hidden sash variant for uniform exterior aesthetics.
MB-86N Fold Line – Folding door version for wide openings and panoramic views.
