Glass Wool Blanket

Glass Wool Blanket is a flexible and roll-type core product of glass wool insulation materials, manufactured by centrifugal blowing of molten glass into fibrous form, spraying thermosetting resin, and undergoing thermal curing and rolling forming. It inherits all the excellent inherent properties of glass wool, with outstanding thermal insulation, sound absorption, fire resistance and hydrophobic performance, and features flexible cutting, convenient construction and wide adaptability. It is a cost-effective insulation and noise reduction material widely used in construction, industry, HVAC and other fields, and can be customized into different specifications to meet the diverse construction and application needs of various engineering projects.

Core Performance Features

Superior Thermal Insulation Performance

It has a low thermal conductivity coefficient (ranging from 0.034 to 0.050), and the loose fibrous structure forms a large number of closed air chambers, which can effectively block heat conduction and convection, and stably exert heat preservation and heat insulation effects in both high and low temperature environments. At the same time, it has low moisture absorption rate and high hydrophobicity (up to 90%), which can avoid the decline of insulation performance caused by water absorption in humid environments.

Excellent Sound Absorption & Noise Reduction

The fine and disorderly glass fiber structure can effectively absorb sound waves of different frequencies, convert sound energy into mechanical energy and dissipate it, thereby reducing noise reflection and transmission. It can significantly improve the acoustic environment of the space and is suitable for various noise reduction scenarios such as building interior and industrial workshops.

Grade A Non-combustible Fire Resistance

As an inorganic non-combustible material, it reaches the Grade A (A1) non-combustible standard for building materials. It does not burn, does not produce open fire and toxic smoke when exposed to high temperature or fire, and can effectively block the spread of fire, providing reliable fire safety protection for buildings and equipment.

Stable Physical & Chemical Properties

It has good chemical stability, is not easy to react with acids, alkalis and other chemical substances, and is corrosion-resistant and aging-resistant; its physical performance is stable, with low density and good toughness, and it is not easy to crack or break during construction and use, ensuring long-term use effect.

Environmentally Friendly & Harmless

The standard glass wool blanket is free of asbestos, formaldehyde and other harmful substances, and the environmentally friendly modified types (such as formaldehyde-free glass wool blanket) further eliminate toxic and harmful components, complying with green building standards and ensuring the health of construction and use personnel.
