Fire-resistant calcium silicate board for modern construction — fireproof partitions, suspended ceilings, structural steel cladding, fire-rated walls, fire door cores, and wet-area applications. A1 non-combustible, up to 240 minutes fire resistance, dimensionally stable in humid conditions.
Modern building codes require passive fire protection throughout commercial, institutional, and high-rise residential buildings. Calcium silicate boards are the preferred choice for fire-rated walls, ceilings, and structural protection because they combine A1 non-combustible performance with excellent dimensional stability in humid conditions.
HR RHINO calcium silicate boards are tested and certified for fire resistance ratings up to 240 minutes (4 hours) according to EN 13501-1 and BS 476. Unlike gypsum boards that lose strength when wet, our products maintain full performance after drying — making them ideal for bathrooms, kitchens, and humid environments.
Typical applications include fire-rated partitions and walls, suspended ceilings, structural steel cladding, fire doors, stairwells, elevator shafts, lift lobbies, and exterior wall systems. Our boards are non-combustible, asbestos-free, machinable with standard tools, and safe for installers and occupants.
Six building applications where HR RHINO calcium silicate boards deliver certified fire protection, thermal insulation, and dimensional stability.
Interior partitions and dry walls in commercial buildings, hospitals, schools, and high-rise residential projects. Achieves fire resistance ratings from 30 to 240 minutes depending on thickness and construction detail.
Passive fire protection for columns, beams, and steel structures. Protects load-bearing steel from reaching critical temperatures (538°C) during a fire, maintaining structural integrity and allowing safe evacuation.
Fire-rated ceiling systems for offices, shopping malls, airports, and public buildings. Smooth surface accepts paint and decorative finishes while providing acoustic insulation and fire separation.
Critical escape routes and service shafts require the highest fire ratings. Our high-performance boards create fire-rated enclosures for stairwells, elevator shafts, service risers, and ventilation shafts.
Bathrooms, kitchens, swimming pools, and humid environments. Unlike gypsum boards, calcium silicate maintains dimensional stability and strength when exposed to moisture, with full recovery after drying.
External wall systems, soffit panels, and infrastructure applications including tunnels, metro stations, and parking garages. Weather-resistant boards provide fire protection and thermal insulation for demanding outdoor environments.
Engineered for modern building codes and architectural demands.
Classified A1 under EN 13501-1. Does not burn, does not contribute to fire load, and emits no toxic smoke in fire conditions.
Certified fire resistance from 30 to 240 minutes (4 hours) per EN 1364, BS 476, and UL ratings — meeting all major building codes.
Maintains dimensional stability and strength in humid environments. No swelling, warping, or degradation — ideal for wet areas.
Smooth surface accepts paint, wallpaper, tile, and decorative finishes directly. No special primer required for most applications.
Cut with standard tools. Fastens with regular screws or nails. Compatible with standard steel stud framing systems.
