This fibrousinsulation is one of a variety of mineral wool.It is made by stretching silicon fibers with additions of limestone, soda ash, dolomite, borax and so on. With the addition of synthetic binding agents.It differs from other types of mineral wool that has a higher wool fibers thickness and better elasticity.

Specifications glass

thermal conductivity of glass is 0,039-0,05 W / m * K.Heat insulator in glass wool acts as the very air that fills the cavity formed between the woven fiber.It can be operated at temperatures up to 450 degrees.

insulation properties:

  • low thermal conductivity;
  • good sound insulation characteristics;
  • combustibility;
  • elasticity and compressibility;
  • lightness and ease of installation;
  • durability.

Application glass

Modern glass wool - non-combustible insulation, which is used for roofing insulation, interior and exterior walls and partitions, floors and ceilings of residential and technical facilities.Provided good water resistance can be glass wool to insulate the facades.Reviews about the insulation for decades consistently good.It is ideal for insulating the garage and basement.The photo and video you can see the many options for the application.When installing the boards it is compressed and forms a monolithic thermal insulation coating without thermal bridges.


One of the main advantages of glass in front of basalt mineral wools - its cost.It is much cheaper at the expense of more affordable cost of raw materials and due to cheaper transportation.Fiberglass has excellent compressibility and elasticity and is capable of up to 6 times to reduce its volume in the package.When unpacking for 20-40 minutes, it recovers its volume.The most famous glass manufacturers such as Isover, Ursa, Rockwool and others. Glass wool is produced in slabs, rolls and mats can be produced and reinforced with a reflective layer.

Disadvantages Disadvantages include excessive water absorption.When installing the steam, it is imperative.When napityvanii moisture insulation degrades its insulating properties to 40%.In addition, when water napityvanii fibers irreversibly alter its structure more fragile.

When mounting must use personal protection: When working with glass wool separated from her tiny glass fibers that can enter the lungs when breathing or cause irritation of the skin.

difference between mineral wool and glass wool

Comparing the mineral wool and glass wool, we can say that this is essentially the same type of material asthe concept of mineral wool according to GOST 31913-2011 following cotton varieties include: the very glass wool, rock wool and slag wool.
