What Is Glass Wool? Features, Applications, and Precautions

What Is Glass Wool?

Glass wool is an insulation material made from fine glass fibers, created by melting sand, limestone, and recycled glass at high temperatures. It is known for its excellent thermal insulation, soundproofing, and fire resistance.

Key Features

• Withstands temperatures from -50°C to 350°C.

• Hollow fiber structure provides effective sound absorption.

• Non-combustible and fire retardant.

• Lightweight, flexible, and easy to install.

Applications

• Used in walls, ceilings, and roofs for thermal insulation.

• Applied in HVAC ducts to retain temperature and reduce noise.

• Common in industrial heat equipment like boilers and pipes.

Notes

• Choose aluminum-foil coated types for better performance.

• Use protective gear during installation to avoid irritation from fibers.
