1. What is the thermal conductivity of this insulation material?
The material has a thermal conductivity of ≤0.030 W/(m.k) at -20°C, ≤0.032 W/(m.k) at 0°C, and ≤0.036 W/(m.k) at 40°C tested in accordance with ASTM C 518 standards.
2. What fire rating standards does this product meet?
This insulation achieves a Class 0 and Class 1 fire rating according to BS 476 Part 6 & Part 7, and has a Flame Spread and Smoke Developed Index of 25/50 under ASTM E 84.
3. How does the insulation improve building energy efficiency?
By providing high thermal efficiency, it keeps the building warmer in winter and cooler in summer, thereby significantly reducing energy consumption for heating and cooling systems.
4. Can this material help with noise reduction?
Yes, it is designed to reduce the transmission of exterior sound to the interior of the building and absorb reverberating sounds within the structure.
5. Is the material resistant to environmental factors like UV and ozone?
Yes, the insulation material demonstrates "Good" resistance to ozone (tested via GB/T 7762-1987), fungi (ASTM G21), and U.V. radiation & weathering (ASTM G23).
