Why: glass wool is the most POPULAR heat and sound insulation product on the market?
Glasswool is an insulation material made from fiberglass, using a binder with a texture similar to wool or cotton. This material traps air between the fibers of the glass and thus, such air pockets result in high thermal insulation properties.

How is glass wool formed?

Natural sand or recycled glass is mixed and heated to 1450 °C to obtain glass mass. Fiberglass is made according to the following method: under the action of centrifugal force, in a drum without a rim, the glass mass passes through a fine mesh, cools and solidifies when exposed to air. Mechanical strength is achieved due to the adhesive properties of individual fibers and the addition of special binding elements. The resulting wool fabric is cut and packaged in rolls or boards, stacked and stored in a warehouse until sold.
» Many people often ask the question - does glass wool burn? Due to its structure and very high melting point (over 1000 °C), glass wool is non-flammable and is an ideal fireproof material.
In addition to the main advantages, the properties of glass wool allow it to be used as a fireproof material to protect structures from destruction in case of fire, as well as ensure safe evacuation of people from building. The high density of non-flammable glass wool does not allow flames to develop (highest non-flammable grade A1), prevents the spread of fire, and does not emit toxic gases when exposed to high temperatures.
» This excellent property of non-combustible materials is widely used in various industries, cotton wool is used as heat and electrical insulation for walls, pipes, containers and various structures . Therefore, to the question: does glass wool burn or not, the answer is obvious.

Main benefits when using glass wool:

  • Low cost
  • Easily cut with hand tools
  • Flexibility and softness allow it to be placed in any hard-to-reach place
  • Does not burn, reacts weakly to high temperatures, does not deform
  • Many choices of sizes and densities
  • high compressive strength
  • High resistance to significant tensile loads
  • Low weight.
