Canglong supplies rock wool fireproof boards to Costa Rica
Recently, 50mm thick rock wool fireproof boards (covering wall panels and roofing panels) customized by Canglong Group for a customer in San José, Costa Rica, successfully arrived at the destination port. The customer has already picked up the goods and transported them to the construction site. This batch of products has passed rigorous quality inspection and fully complies with Costa Rica’s SIRP building code and international fire safety standards, providing a superior three-in-one solution for local warehousing and commercial projects, combining fire resistance, energy saving, and weather resistance.
Core Advantages of Rock Wool Fireproof Boards
This batch of rock wool sandwich panels uses a high-density rock wool core material (density 40kg/m³) and a double-layer galvanized steel plate composite structure, achieving a fire resistance rating of A1 (GB 8624-2012). It can withstand fire for more than 120 minutes at 1000℃, far exceeding the 60 minutes required by Costa Rican building codes. Its core rock wool material possesses inorganic mineral properties, meaning it does not burn or produce toxic fumes when exposed to fire, effectively preventing the spread of fire and providing a zero-risk fire barrier for buildings. SGS testing reports show that the product’s fire resistance performance has been certified by a third-party authority and fully meets the stringent fire safety requirements of Costa Rica.
Energy Saving and Weather Resistance
Targeting Costa Rica’s climate, characterized by an average annual rainfall of 2200mm and high temperatures and humidity, rock wool sandwich panels exhibit superior comprehensive performance. Its thermal conductivity is as low as 0.035 W/(m·K), significantly reducing indoor temperature fluctuations, lowering the temperature by more than 8°C compared to ordinary materials, and achieving an average annual energy saving rate of 25%, greatly reducing air conditioning energy consumption. Simultaneously, the rock wool core material has a water absorption rate of less than 1%, and the surface is coated with a moisture-proof coating, ensuring long-term stability and preventing moisture absorption and deformation in rainy environments. Its wind pressure resistance reaches 1.5kPa, perfectly adapting to the local strong wind climate and earthquake zone environment. Actual testing shows that the product’s service life is extended to over 20 years under high temperature and humidity conditions, far exceeding the industry average.
Dual Guarantee of Quality and Efficiency
Canglong Group maintains strict control over the entire delivery process: product thickness is precisely controlled at 50±0.5mm, with uniform density. SGS test reports are included with the goods, complying with RoHS environmental standards (non-toxic and odorless); temperature-controlled protection throughout logistics ensures undamaged and unchanged arrival. This delivery was 48 hours ahead of the contract. On-site inspection by the client showed that the wall and roof panels were smooth and scratch-free, fully meeting the stringent safety requirements of Costa Rica’s SIRP regulations.
Client Value
The efficient application of this rock wool fireproof boards directly helped the client pass fire safety inspection two weeks ahead of schedule, while simultaneously reducing total life-cycle operating costs. In the Costa Rica warehousing project, its energy-saving characteristics reduced annual energy expenditure by 18%, and its 20-year maintenance-free lifespan significantly reduced later maintenance costs. The client highly praised: “The precise selection of 50mm thickness allows the building to achieve the optimal balance between fire resistance and energy efficiency; this is not just a product, but a dual guarantee of safety and economy.”
Canglong Group continues to provide customized building solutions to clients worldwide. By setting a new benchmark for the Costa Rican construction industry with its green and safe concepts, the company is accelerating the region’s progress towards low-carbon, efficient, and sustainable construction. In the future, Canglong Group will continue to deepen its global cooperation, providing Chinese solutions to meet the building safety and energy conservation needs of more countries.
