Product Overview
Glass Wool Roll Key Features
-
Superior Flexibility & Resilience: Soft and bendable, easy to wrap complex pipelines and irregular equipment, quick rebound after compression without deformation.
-
High-Efficiency Thermal Insulation: Low thermal conductivity effectively blocks heat transfer, cuts energy consumption and ensures stable glass wool blanket insulation performance.
-
Excellent Sound Absorption: Porous fiber structure absorbs noise and weakens sound transmission, ideal for soundproof and noise reduction scenarios.
-
Class A Non-Combustible: Inorganic glass fiber material, zero flammability, complies with strict international fire safety standards.
-
High Hydrophobicity: Low moisture absorption rate, resists mold and corrosion, maintains performance in humid environments.
-
Lightweight & Easy Construction: Ultra-light design reduces structural load, easy to transport, cut and install on site.

Glass Wool Blanket Main Applications
1. Building Wall Insulation
Glass wool roll is widely used for cavity walls, timber frame walls, and steel stud partitions in commercial, residential, and industrial buildings. The flexible rolls are easy to install between studs, providing continuous thermal insulation and reducing energy consumption.
2. Roof and Attic Insulation
Glass wool blanket is ideal for insulating pitched roofs, attics, and loft spaces. The flexible rolls conform easily between rafters and joists, providing thermal efficiency and acoustic damping. Lightweight design simplifies installation in overhead applications.
3. HVAC Duct Insulation
Heating, ventilation, and air conditioning ductwork requires insulation to prevent thermal loss and condensation. Glass wool roll with aluminum foil facing provides both thermal insulation and vapor barrier protection for rectangular and circular ducts.
4. Suspended Ceilings
Glass wool blanket placed above suspended ceiling grids provides acoustic absorption and thermal insulation for commercial offices, schools, hospitals, and public buildings.
5. Industrial Equipment Insulation
Industrial machinery, tanks, vessels, and process equipment benefit from glass wool roll insulation. The flexible material wraps easily around irregular surfaces and equipment, reducing heat loss and protecting personnel.
6. Acoustic Treatment and Soundproofing
Glass wool blanket with high sound absorption coefficients is used for acoustic panels, soundproofing layers in walls and ceilings, and industrial noise control applications.
7. Metal Building Insulation
Pre-engineered metal buildings, warehouses, and agricultural structures use glass wool roll insulation installed between purlins and girts, often with vinyl facings for condensation control.
8. Marine and Offshore Accommodation
Marine vessels and offshore platforms use glass wool blanket for accommodation area insulation, providing fire protection, thermal comfort, and acoustic privacy.
