The aluminum foil covered rubber foam sheet roll has excellent thermal insulation with very low thermal conductivity. It also provides outstanding acoustic insulation, designed to effectively reduce environmental noise and control sound transmission.
Frequently Asked Questions
Q
What is the fire safety rating of this rubber foam insulation?
It features a highly robust fire rating of Class 0 & Class 1 (tested under BS 476 Part 6 & 7) and a Flame Spread/Smoke Developed Index of 25/50 (ASTM E 84). It is self-extinguishing, produces no falling flames, and prevents flame spread.
Q
How low is the thermal conductivity of the foil-covered foam?
The insulation has exceptional thermal performance. Under ASTM C 518 test standards, thermal conductivity values are ≤0.030 W/(m.k) at -20°C, ≤0.032 at 0°C, and ≤0.036 at 40°C.
Q
Does this product offer acoustic noise reduction?
Yes, in addition to thermal insulation, the structural configuration of our rubber foam sheet roll provides excellent sound absorption properties to reduce noise and lower sound transmission.
Q
What temperature limits can these foam sheets withstand?
The sheet has an operational temperature range from -50°C up to 110°C, meeting GB/T 17794-1999 specification standards.
Q
Is the insulation resistant to environmental weathering and fungi?
Yes. According to standardized testing, the product shows good resistance to fungi (ASTM 21), ozone (GB/T 7762-1987), and UV/weather exposure (ASTM G23).
