FRP (Fiber Reinforced Plastic) sandwich panels are advanced composite materials used in construction and industrial applications for walls, roofs, and ceilings. These panels consist of three layers: a core material sandwiched between two outer layers of FRP. The core is typically made of a lightweight insulating material such as polystyrene, polyurethane, or mineral wool, while the outer layers are made of durable FRP, providing strength, weather resistance, and protection against corrosion. FRP sandwich panels are known for their excellent thermal insulation properties, making them ideal for energy-efficient buildings. The insulating core helps maintain temperature stability within the building, reducing heating and cooling costs. The FRP outer layers add structural integrity, making the panels strong, durable, and resistant to impact, chemicals, and environmental conditions. These panels are lightweight yet strong, making them easier to handle and install compared to traditional building materials. They also offer a high level of fire resistance, depending on the core material used, contributing to the overall safety of the structure. Additionally, FRP sandwich panels are highly resistant to moisture, mold, and rot, making them suitable for use in humid and harsh environments.
