Centrifugal glass wool is a silk-like material made by fiberization in the TEL process and
spraying of thermosetting resin.  Glass wool is non-combustible,
non-toxic, and resistant
to corrosion. It has low weight by volume, low thermal conductivity, stable chemical
property, and low moisture absorption rate due to its excellent hydrophobicity. Thanks to
its intertwined flexible fibers, glass wool is the best insulating material against noise, cold
and heat and also offers excellent fire-resistant properties. The panel, felt, and pipe
products made of glass wool have been used in the industries of construction, chemical,
electronic, energy, metallurgy and communication.

We offer high quality glass wool felt in rolls that is soft, waterproof and fireproof with
good elasticity (a veneer of reinforced aluminum foil can be applied), providing an ideal
thermal and sound insulation for steel structure constructions. The glass wool felt offers
the advantages of low material cost, short work cycles and fine appearance. It is also
friendly for worker safety as it is non-toxic and non-irritant to skin.

Glass wool boards are widely used as insulation material for exterior and interior walls
(click
here for examples). In addition to its characteristic advantage in thermal insulation,
it is excellent in noise reduction. The latter property makes it an ideal choice for wall
partition in conference rooms, hotels and residential homes. The material is light and
thin, which allows more space as useful floor area.

Our centrifugal glass wool products are categorized in boards or panels, felt and tubes in
various color.  The panels may feature a layer of reinforced aluminum foil for enhanced
exterior appearance, and are ideal for the insulation of production or storage facilities for
minimum cost, yet nice appearance and effective insulation.  Examples are shown in this
page.

We carry specialty glass wool products such as
Refractory Glass Wool, Air
Conditioning Duct and Air Condition Insulation Panel.  In addition, we offer
Double-sided Aluminum Foil.

We can meet specifications (dimensions, thickness, density, color etc) as desired by
customers.
