MB-100GFT – Commercial door and ground floor treatment system
Bertrand MB-100GFT system is a modern, thermally broken aluminum solution designed for ground-floor entrances, storefronts, and high-traffic commercial areas.
Combining exceptional durability, thermal insulation, and ease of fabrication, it’s the ideal choice for architects, developers, and contractors who need a robust, energy-efficient door and shopfront system that withstands intensive daily use.
This system is specifically engineered for single and double doors, as well as modular shopfront constructions.
Its structure ensures both thermal efficiency and mechanical strength, while maintaining a clean, modern aesthetic. The system’s modular design allows for fast fabrication and installation, reducing lead times and simplifying production.
Two thermal variants are available:
- MB-100GFT ST – the standard version with solid insulation performance.
MB-100GFT SI – the enhanced version featuring additional EPS or polyethylene thermal inserts for superior energy efficiency.
Key features & benefits:
Flexible door operation: Supports inward, outward, or dual-action opening configurations.
Two thermal variants: ST or SI, depending on insulation requirements.
High thermal performance: Low Uf-values achieved through advanced thermal breaks and EPS/polyethylene inserts.
Durable construction: Designed for heavy commercial use, tested to Class 8 durability (1,000,000 cycles, EN 12400).
Enhanced safety: Optional anti-finger trap hinge profiles and concealed transom closers improve user safety.
Low threshold design: Standard Part M compliant low-level threshold for accessibility and barrier-free entry.
Security options: Compatible with 1-point or 3-point locks, panic hardware, and PAS 24-certified glazing bead design for burglar resistance.
Weather protection: Choice of standard brush seal or brush with integral barrier fin for improved air and water tightness.
Shopfront adaptability: Segment-based shopfront modules include starter profiles for easy drainage and leveling, as well as snap-on profiles for fast assembly.
System compatibility: Fully compatible with other Bertrand aluminum systems, allowing shared components like glazing beads, gaskets, and accessories.
Simplified fabrication: Modular design reduces production time and supports efficient installation.
