Acoustic Materials Glass Wool Blanket Environmental Protection
Introduction
Formaldehyde-free glass wool belongs to a category of glass fiber, is a kind of man-made inorganic fibers.Glass wool is the molten glass fibrosis, forming wool material, chemical composition is glass, is a kind of inorganic fiber, has good shape, small volume density, low thermal conductivity, excelle thermal insulation and sound-absorbing performance, corrosion resistance, stable chemical performance do not contain any formaldehyde, no harm to human health, is a new kind of environmental protection heat preservation and heat insulation material.
The Usage of Glass Wool
Glass wool was used for building materials , and steel structure insulation.
Soundproof and fireproof used for wall and roof of house.
Heat preservation for steel structure building, heat Insulation for wall and roof of house to save energy.
Steel structure buildings heat insulation,cold insulation and sound absorption.
Air-conditioning duct system out wall heat/cold insulation, inner wall sound proof.
Dry wall systems.
Advantages
* There is high rate of sound-absorption and insulation effect.
* The surrounded frame is wooden or resin, the sense of beauty is obvious by piecing
* The shell material is made of fireproof Fabrics or Artificial Leather, and all kinds of color is available, the outlook is not only beautiful but also elegance.
* It is easy construction, good decoration,Various colors for choosing. Fiber glass wool acoustic materials Sound-absorption theory.
