Product Details

Glasswool Blanket

Description

Glasswool blankets are manufactured from a unique rotary flame attenuation process incorporating highly resilient, inorganic glass fibres bonded with a thermosetting resin to form a lightweight, flexible and resilient insulation material.Apart from providing good thermal insulation qualities, it is also an effective sound absorption material. The glasswool blanket also can be coated with facing, such as alu foil, fiber cloth, polypropylene, fiber tissue etc. according to the requirements of different uses.

Also we accept OEM for different brands of products based on requirements of customers.

Advantages

Unique technology, rebound degree after compressive packing is up to 99.2%
Soft and long glass fibers can maximally lessen flying catkins in the construction
Sound absorption and noise reduction, it can effectively prevent sound from spreading
Grade A1 incombustible materials
Easy for construction, cutting at will
Antisepsis, ageing resistance, and anticorrosion, ensuring a healthy environment
Low moisture absorption, stable physical properties

Design of sound absorption
The requirements of buildings on sound absorption should be calculated according to the following acoustical property of glasswool felt to determine product specifications.
Sound absorption coefficient (glasswool felt with facing)
Testing and installation method A of noise reduction coefficient: Heat insulation materials are tightly stuck on rigid
surface of brick wall or sth similar
Sound absorption coefficient (glasswool felt without facing)
Testing and installation method A of noise reduction coefficient: Heat insulation materials are tightly stuck on rigid
surface of brick wall or sth similar
Sound installation coefficient (unit: db)
Remarks: STC-testing and installation method of sound insulation coefficient•ASTM E90,unit or R in the above: h•ft2•ºF/Btu

Applications
Glasswool Blanket is commonly used for the underside of metal roofing in industrial projects for insulation purposes. It can also be extensively used for all types of residential and commercial projects. The glasswool can either be installed between the roof trusses or just above the ceiling. Single sided or double sided aluminium foil has to be placed below the glasswool blanket for vapour barrier application.
