As a green and energy-saving roof lighting material, FRP lighting board has been widely used today in the 21st century. FRP lighting board manufacturer Mcwell has undertaken many steel structure roof lighting board projects. Mcwell simply talks about the characteristics of the lighting board.

1. Thermal stability: The thermal expansion coefficient of FRP daylighting board is 2.5～3.5×10-5 (m/m/℃), which is closer to steel than PVC and PC, reducing the stress caused by cold and heat changes and causing water leakage at the joints.

2. Flame-retardant performance: With different formulations, excellent flame-retardant performance can be obtained and meet the requirements of the national standard. (Runfeng Class II flame-retardant lighting board OI≥26;).

3. Light transmittance: The light transmittance of FRP daylighting board is between 25% to 85%. The special process technology makes the incident light very soft and creates a working environment. Moreover, as a non-uniform material composite material, the light is scattered when passing through, so that the light of the steel structure factory building is uniform, no spot, and no dazzling. Due to the use of raw materials and Mcwell's technology, the resulting product has a clean appearance and the light transmittance meets the national standard

4. Decorative effect: FRP daylighting board adopts continuous molding process. By adjusting the formula and process parameters, various products of different colors can be obtained, which is suitable for decoration engineering.

5. Weather resistance: The surface is coated with weather-resistant gel coat or anti-aging film to improve the aging resistance of the product; the ultraviolet absorber in the daylighting board can filter more than 90% of the ultraviolet rays in the sun and slow down material degradation and discoloration. The service life can reach 20 years. The surface of FRP products is covered with a weather-resistant film, which can greatly increase its service life.
