Trapping static air to block heat conduction
Its dense porous fiber structure creates numerous tiny air pockets. Static air is a poor heat conductor, so these pockets act as a barrier to slow down heat transfer, achieving thermal insulation.
Absorbing radiant heat (enhanced with aluminum foil)
For rock wool blankets with aluminum foil, the foil layer reflects most radiant heat back to the source, preventing radiant heat penetration and enhancing insulation efficiency.
Damping sound transmission through fiber vibration
Sound waves penetrate the porous structure and cause fibers to vibrate. This vibration dissipates sound energy into weak heat energy, weakening sound transmission and achieving sound absorption.

Rock wool blanket features A1-class non-combustibility, excellent thermal/sound insulation and temperature resistance, plus flexibility and easy cutting/installation. It suits thermal insulation, fire protection, and noise reduction needs across industrial production, civil buildings and special facilities, serving as a safe and practical multi-functional insulation material.
Industrial High-Temperature Equipment & Kilns Insulation: Directly wrapped/attached to boilers, kilns, hot blast stoves, etc. Blocks high-temperature loss, reduces energy consumption, protects the surrounding environment, and adapts to working conditions over 750℃.
Cold Chain & Low-Temperature Warehousing Insulation: Used in refrigerated truck compartments and freezer walls/ceilings. With aluminum foil facing, it boosts moisture/vapor resistance, prevents heat penetration, maintains stable low temperature, ensures cold chain cargo quality, and resists brittleness at low temperatures.

Q: What is the maximum temperature the rock wool blanket can withstand?
A: Generally, it can withstand temperatures up to 750℃. The exact tolerance may vary slightly based on the product’s thickness and density.
Q: How should it be cut and fixed?
A: Standard cutting tools are sufficient for trimming. Secure it to pipes or frames using ties, clips, or additional wire for a firm fit.
Q: What is its fire rating?
A: It’s classified as A-grade non-combustible (A1 grade as per the table). We can provide official test reports to verify this rating upon request.
