The MB-86N SI system is recommended for energy-saving construction. It is highly durable and guarantees top aesthetics and excellent thermal and acoustic insulation properties. It creates great design possibilities and allows for the creation of doors that are even 3 meters high. Windows based on the MB-86N SI system also meet the highest requirements for air permeability as well as water and wind resistance.

MB-86N SI:

• Window frame installation depth: 77 mm
• Construction depth: 77 mm
• Sash depth 77 mm (window) / 86 mm (door)
• Maximum sash dimensions: 1700 mm x 2400 mm
• Maximum sash weight: 150 kg
• Glazing thickness: up to 58.5 mm (frame)/ 67.5 mm (sash)
• 3-chamber construction with a thermal break
• Multi-component central gasket perfectly insulating the space between sash and frame
• High profile strength for making structures of large dimensions and weight
