Yirong rock wool sandwich panels exported to Costa Rica

Yirong Group's customized 50mm thick rock wool sandwich panels (including wall panels and roof panels) for its Costa Rican client have been packaged and shipped, and are about to depart for Central America.

Project Background

Costa Rica is located in the tropics, experiencing high temperatures and humidity year-round, and is also affected by the northeast trade winds, encountering 3-5 strong wind events annually. Traditional color steel plate enclosures have drawbacks such as insufficient fire resistance (mostly Class B), poor thermal insulation, and weak wind resistance, making it difficult to meet the dual demands of modern warehousing for safety and comfort. The introduction of Yirong rock wool sandwich panel is a systematic solution specifically designed for this scenario.

Core Advantages of Yirong Rock Wool Sandwich Panels

1. Fire Safety

Authoritative Certification: Utilizes high-density rock wool core material (density ≥120kg/m³), meeting GB 8624-2012 Class A non-combustible certification and ASTM E136 international standards. It does not release toxic gases when exposed to fire, and its fire resistance limit reaches 1.5 hours.

Practical Application: Costa Rican warehouses often store flammable goods such as agricultural supplies and food. Class A fire resistance reduces the risk of fire spread, providing double protection for goods and personnel.

2. Thermal Insulation

Data Support: With a thermal conductivity as low as 0.038W/(m·K), a 50mm thickness can achieve an indoor-outdoor temperature difference of ≤5℃ in summer and reduce winter insulation energy consumption by 30%.

Technical Principle: The three-dimensional structure of rock wool fibers forms an air gap, combined with double-sided 0.5mm galvanized steel plates, which both block solar radiation heat and reduce indoor cooling loss, making it suitable for the high-temperature and high-load air conditioning environments of Costa Rica.

3. Wind Resistance and Durability

Wind Resistance: Optimized panel design through finite element analysis, combined with specialized self-tapping screws and waterproof sealing strips, allows it to withstand wind pressure up to level 12, far exceeding the design standard of level 10 winds in the Costa Rican coastal region.

Weather and Corrosion Resistance: The steel plate surface is coated with a PVDF fluorocarbon coating (film thickness ≥25μm), resisting salt spray corrosion for up to 5000 hours, addressing the salt spray erosion of tropical maritime climates.

4. Comprehensive Benefits

Lightweight Advantage: Weighing only 12kg/m² per unit area, reducing structural load by 20%, indirectly lowering foundation costs.

Construction Efficiency: Modular design supports dry construction, with a single shift of workers installing an average of 150m² per day, meeting the rapid delivery requirements of Yirong's one-stop solution.

Delivery and Service

The rock wool sandwich panels delivered this time strictly adhere to the Costa Rican standards for tropical warehouses:

Customized Sizes: Wall panels are cut according to the customer's warehouse facade module, and roof panels are adapted to the portal frame slope (5°), reducing on-site secondary processing.

Supporting Accessories: Special sealing strips, windproof clips, and corner trims are shipped simultaneously to ensure airtight installation.

Logistics Tracking: GPS positioning of containers is used to track sea freight progress in real time, and local customs clearance guidance is provided.

Market Potential of Rock Wool Sandwich Panels

With the increasing adoption of global ESG building standards (such as LEED and BREEAM), fireproof, thermal insulation, and low-carbon integrated enclosure systems have become a necessity for upgrading warehouses in tropical regions. Yirong Rock Wool Sandwich Panels, through material innovation, structural optimization, and customized service models, has already been implemented in multiple benchmark projects in the Caribbean region (Curaçao and Jamaica).
