Insulation Application Example
Frequently Asked Questions (FAQ)
The thermal conductivity of our elastomeric insulation ranges from ≤0.030 W/(m.k) at -20°C to ≤0.036 W/(m.k) at 40°C, tested in compliance with ASTM C 518 standards to ensure optimal thermal efficiency.
This material is engineered to operate stably in a broad temperature spectrum from -50°C up to 110°C, making it suitable for a wide range of HVAC, industrial, and building system installations.
Our insulation achieves Class 0 and Class 1 ratings under BS 476 Part 6 & 7. Additionally, it has a Flame Spread and Smoke Developed Index of 25/50 according to ASTM E 84, alongside an oxygen index of ≥36.
Yes, our rubber foam features high water vapor permeability resistance (μ ≥ 10000) and displays excellent performance against fungi (ASTM 21), ozone (GB/T 7762-1987), and UV/weather exposure (ASTM G23).
The insulation rolls are available in multiple thickness options (from 1/4" to 2") and widths of 1m, 1.2m, and 1.5m. Roll lengths adjust dynamically based on thickness to optimize roll area (m²) and facilitate ease of installation.
