Applications of Insulated Fire-Resistant Roller Shutters
- In airports, aircraft parking areas, and hangar entrances,
- In large-scale industrial production facilities and commercial buildings,
- In loading stations and cold storage facilities,
- In industrial zones and factory or warehouse areas within large-scale developments,
- In production facilities and buildings with high fire and explosion hazards, such as chemical, pharmaceutical, textile, furniture, wood, and electrical systems,
- In buildings with fire and explosion risks,
- In the automotive industry, vehicle parking areas,
- In buildings with high user traffic, such as schools, hospitals, hotels, shopping malls, and parking garages,
- In all types of buildings, both interior and exterior, requiring acoustic, insulation, radiation shielding, and wind resistance properties.
Advantages of Insulated Fire-Resistant Roller Shutter Doors
- In the event of a fire, insulated and fire-resistant revolving doors act as a structural barrier in full-height openings to compartmentalize the building and prevent the spread of fire. Doors equipped with fire signals from the building’s alarm system can safely open and close at a reliable speed.
- Roller shutter door system is designed to be activated by a signal from the building’s fire and automation systems during a fire. When the signal is received, the door closes, preventing the spread of the fire throughout the building while allowing for the safe evacuation of users.
- In addition to being designed for fire-resistant wide openings, fire-resistant revolving doors ensure safe entry, exit, and access control in large openings under normal usage conditions.
- Insulated and fire-resistant revolving door systems allow investors and business owners to manage both high-security control and energy efficiency. The mineral wool inside insulated revolving doors plays a significant role in maintaining temperature differences between interior and exterior spaces, as well as reducing sound transmission, noise, and dust ingress and egress.
- For building owners and designers who demand the highest level of life and property protection, these doors are a clear and reliable choice for fire safety.
Steel Roller Shutter Door Profile Details
Technical Specifications
- Single-Wall Profiles: Profiles/curtains made from galvanized interlocking roll-formed steel. Single-wall, perforated or non-perforated profiles, 80 mm curved slat or 110 mm flat slat. Sheet thickness ranges from 0.80 mm to 1.20 mm. The profile/curtain allows ventilation (approximately 25% air passage) and/or ensures the required security while providing visibility from behind.
Model No: NS80 / NS80D / NS110 / NS110D - Double-Wall Profiles: Profiles/curtains made from galvanized interlocking roll-formed steel. Double-wall insulated profiles, 100 mm flat slat, 77 mm and 90 mm curved slats, sheet thickness of 2.00 mm, nominal thickness of 18.5 mm and 24 mm. The profile/curtain is filled with rock wool or polyurethane foam to provide excellent thermal and acoustic insulation.
Model No: NS100/PU | NS100/RW | NS77/PU | NS90/PU - Cage Profile: Made from galvanized steel, stainless steel, or aluminum, with a curved diamond-shaped tube profile of 1.00 mm or 1.20 mm thickness, connected with 3.00 mm thick fastening components. The profile/curtain provides maximum visibility, ventilation, and security while ensuring the required safety.
Model No: NS14-NS18 - PCP Profile: A profile/curtain made from polycarbonate (PCP) material, single-wall, with 77 mm flat slats and a nominal thickness of 3.00 mm. It is fully transparent, ultra-light compared to steel profiles. It is unbreakable, corrosion-resistant, fire-retardant, and 100% UV protected. Integrated with a Ø16 2.00 mm aluminum pipe profile.
