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

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.
