Frequently Asked Questions (FAQ)
What are the main application benefits of this insulation material?
This material is designed to significantly improve building energy efficiency, optimize thermal retention (keeping interiors warmer in winter and cooler in summer), and reduce noise transmission by absorbing reverberating sounds within the structure.
What are the available dimensions and thickness options?
We offer normal wall thicknesses ranging from 1/4”, 3/8″, 1/2″, 3/4″, 1″, 1-1/4”, 1-1/2″ up to 2” (which corresponds to 6, 9, 13, 19, 25, 32, 40, and 50mm). The standard lengths provided are 6ft (1.83m) or 6.2ft (2m).
How does this product perform under fire ratings?
It meets strict fire protection requirements, achieving a Class 0 & Class 1 rating according to BS 476 Part 6 and Part 7 test standards. It also achieves a Flame Spread and Smoke Developed Index of 25/50 under ASTM E 84.
What is the thermal conductivity (K-value) performance of this material?
Tested under ASTM C 518, the thermal conductivity values are extremely low: ≤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, ensuring reliable, age-long thermal efficiency.
Is this insulation material resistant to moisture and environmental degradation?
Yes, it features a high moisture resistance factor (μ-value ≥ 10000) and displays excellent performance against weathering, UV exposure, ozone degradation, and fungi growth, assuring long-term durability.
Can you accommodate custom specifications or bulk order requests?
Yes, OEM orders and customization services are fully supported. We offer high production efficiency for quick delivery times, competitive pricing for win-win cooperation, and significant discounts for large volume orders.
