Aquaculture panels are insulated sandwich panel systems engineered for fish farms, hatcheries, and recirculating aquaculture systems (RAS) where continuous high humidity, ammonia release, and salt spray rapidly corrode conventional steel cladding. The inner skin replaces standard steel with white fiberglass-reinforced polyester (FRP), a non-porous surface that does not rust or deteriorate under the acids and corrosive environments of freshwater and brackish species farming.
The polyurethane (PU) foam core delivers thermal insulation at 40 kg/m³ density with thermal conductivity of 0.022 W/(m·K), maintaining the steady water-side temperatures of 22°C to 28°C that protect tilapia, eel, and shrimp populations and sustain feed conversion rates. PIR cores are offered for stricter fire performance, withstanding temperatures up to 350°C before decomposition and reducing HVAC energy consumption by up to 30% versus single-skin buildings.
Standard panel thickness ranges from 30mm to 50mm, with 50mm the most common configuration for fish farming enclosures and indoor pools where temperature control directly determines energy expenditure and yield. Panels are manufactured in a useful width of 1,000mm and custom lengths up to 16,000mm, joined by camlock or tongue-and-groove profiles sealed with polyurethane adhesive to prevent moisture infiltration and condensation.
These insulated panels serve recirculating aquaculture systems, hatcheries and broodstock facilities, indoor fish and shrimp farms, and freshwater or saltwater processing enclosures. The smooth white FRP surface withstands pressurized water and detergent disinfection required for biosecurity, increases interior light transmission to lower lighting costs, and supports a 25-30 year service life when paired with hot-dip galvanized structural framing exceeding 600 g/m² zinc coverage.

Aquaculture Panel Buying Guide & FAQ
Selecting the right aquaculture panel requires understanding corrosion resistance, thermal stability, biosecurity, and humidity control. This guide answers the most common questions from fish farm operators, hatchery managers, and RAS engineers evaluating insulated sandwich panels for intensive aquaculture and indoor farming applications.
1. Why use FRP inner skins in aquaculture panels?
Fish farming environments combine water evaporation, ammonia gas release, and salt spray that rapidly rust standard steel cladding from the inside. White fiberglass-reinforced polyester (FRP) inner skins are non-porous and chemically inert to these corrosive agents, requiring no protective coating, and withstand pressurized washdowns while increasing interior light transmission to reduce lighting energy costs.
2. What temperature range do aquaculture panels maintain?
Using 50mm PU foam panels at 40 kg/m³ density, the enclosure maintains steady internal air temperatures of 22°C to 28°C, the optimal band for tilapia, eel, and shrimp health and feed conversion. This stable envelope reduces HVAC energy consumption by up to 30% compared to single-skin metal buildings, protecting stocking density and yield.
3. How thick should aquaculture panels be?
For open fish farming pools and indoor aquaculture enclosures, 50mm panels are the most common configuration, balancing thermal control with cost where temperature stability is the dominant factor. Thinner 30mm and 40mm options suit milder climates or partition walls, while thicker 75mm to 100mm panels are specified where strict cold or hot climate control is required.
4. Which aquaculture applications use these panels?
These panels serve recirculating aquaculture systems (RAS), hatcheries and broodstock facilities, indoor fish and shrimp farms, and freshwater and saltwater processing enclosures. Their smooth, non-porous surfaces withstand high-pressure cleaning and detergent disinfection between production cycles, supporting biosecurity programs while maintaining thermal integrity for sensitive aquatic species across diverse farming methods.
5. How is corrosion resistance verified for saltwater farms?
The FRP inner skin is inherently inert to ammonia, salt spray, and the acids generated in brackish species farming, eliminating the rust that destroys conventional steel panels within years. Paired with hot-dip galvanized structural framing exceeding 600 g/m² zinc coverage, the system achieves a 25-30 year service life even in humid environments above 80%.
