HUAMEI glass wool is the silk-like material made by fiberizing melted glass and then coated with      thermosetting resin through centrifugal blowing process. After further processing, this material could be      made into series of products for multiple purposes such as glass wool blanket, board, and airconditioning board, and fiberglass duct, refractory glass wool. It features numerous advantages    including non-combustible, non-toxic, resistant to corrosion, low density, low thermal conductivity,
stable chemical property, low moisture rate and good hydrophobic etc. It is widely recognized as the   heat-preservation, thermal insulation and sound absorption material with excellent. The blanket, board    and pipe products made of this material have been used in heat preservation, thermal insulation and  sound absorption in construction, chemical industry, electronic industry, electric power, metallurgy,     energy industry and communication presenting very good result.
It is the best material used for the insulation and sound absorption of steel structures. It is widely used
in the industrial plant, public facility, warehouse, exhibition center’s, shopping mall, cold store and a
variety of indoor playground, sports ground, and other buildings. Meanwhile, it can save energy, absorb
sounds and improve the indoor air quality in many degrees.

Glass wool insulation

Glass wool is an insulating material made from fibres of glass arranged using a binder into a texture similar to wool. The process traps many small pockets of air between the glass, and these small air pockets result in high thermal insulation properties.

Why choose Glass Wool ?

Glass wool products are non-combustible and positioned for operating temperatures up to 350°C.

It is made of 80% recyclable materials

Is poses no health hazards

It is lightweight and easy to install

Glass wool will not promote mold growth or vermin infestation

It is non-corrosive to metal

Applications of Glass Wool Insulation

Our products are widely used in for metal structure buildings’ roof and exterior walls such as commercial
building, warehouse, plant, stadium, exhibition center, shopping mall, public facilities, cold stores and a
variety of indoor playground, sports ground, etc.
