Why are FRP (fiberglass reinforced plastic) daylighting panels superior in terms of durability and safety?

FRP (fiberglass reinforced plastic) daylighting panels, also known as glass fiber reinforced plastic daylighting panels, offer advantages in durability and safety primarily due to two core dimensions: material composition and structural characteristics.

1. Durability Advantage: The Core Capability to Combat Environmental Aging 

The long lifespan of FRP (Fiberglass Reinforced Plastic) skylights primarily relies on their unique material composition, which effectively resists environmental erosion.

Weather Resistance of the Resin Matrix:The surface typically uses highly weather-resistant resins, such as polycarbonate (PC) or unsaturated polyester resin (UPR), which resist aging, yellowing, and embrittlement caused by ultraviolet radiation, rain, and high temperatures.

Reinforcement by Fiberglass:The internal fiberglass mesh acts as a skeleton, providing extremely high tensile and impact strength, effectively preventing deformation and cracking of the panels due to long-term stress or temperature changes.

Low Water Absorption and Corrosion Resistance:Unlike traditional metal or wood skylights, FRP materials do not absorb water, do not rust, and are not corroded by acids, alkalis, or other chemicals, making them suitable for use in humid or corrosive environments (such as chemical plants and farms).

2. Security Advantages: Reliable Protection Against Emergencies

In terms of safety, FRP (fiberglass reinforced plastic) skylights reduce usage risks through their physical properties and structural design.

Impact resistant and not easily broken: Compared to traditional glass skylights, FRP materials are more resilient and less prone to breakage upon impact. Even if damaged, they do not produce sharp fragments, effectively preventing secondary injuries such as cuts.

Good Fire Resistance: By adding flame retardants, FRP skylights can achieve flame-retardant or fire-resistant ratings (such as B1). In the event of a fire, they can slow the spread of fire and do not produce toxic gases during combustion, meeting fire safety requirements.

Thermal Stability and Wind Pressure Resistance: With a low coefficient of thermal expansion, they are less prone to damage due to thermal expansion and contraction during drastic temperature changes. Simultaneously, their high-strength structure allows them to withstand significant wind pressure and snow loads, making them suitable for installation in high-rise buildings or areas with high winds.
