1, low thermal conductivity (λ <= 0.041w/mk), good thermal insulation properties. 

2, anti-noise sound, pitched roof skylight hollow glass can Dangqu 30 db above the noise. 

3, specifications diversification, such as business type, H type, corrugated type, etc., and the bright color, no surface decoration. 

4, aluminum doors and insulation, the heat transfer coefficient of hollow glass skylight sloping roofs using 2.5-4 times smaller than ordinary glass. 

5, non-toxic, odorless core without freon blowing agent, burning non-toxic, odorless, spill gas are harmless to humans and the environment, in line with national environmental requirements, is a new green building materials. 

6, the core part of the waterproof moisture organic polymer foam material is a closed-cell structure, with good resistance to water absorption and resistance to water vapor permeability. 

7, herringbone top sun room lighting is good, the experimental test, inclined roof windows windows higher than the general lighting effect more than 10%. Time to turn on the lights every day one hour later. Meanwhile astrology can enjoy the night, adding fun. 

Eight, installation flexibility not only a significant reduction in composite panels basic engineering and structural engineering construction material costs, and can repeatedly dismantling, installation flexibility, the overall efficiency is very significant. 

9, fire resistance class B1 core material is flame retardant materials, the oxygen index ≥ 26, does not melt when burned, and no smoke, no drip pyrolysis. A high level of fire protection for the domestic architectural composite plates, decorative plates are preferred GMP plant. 

10, herringbone top sun room temperature using a wide range of core temperature at -70 ℃ ~ +120 ℃, the moment of +200 ℃, shrinkage even when used in low temperature cryogenic environment, not brittle, is cryogenic (cold ) ideal engineering insulation.
