glerull

Glerull is a type of insulation material made from glass fibers. It is manufactured by melting glass at high temperatures and then spinning it into fine fibers. These fibers are then bonded together with a resin to create a blanket-like material. Glerull is known for its excellent thermal and acoustic insulation properties. It is commonly used in the construction of buildings to reduce heat loss and sound transmission.

The manufacturing process of glerull involves several steps. Raw materials, primarily sand and recycled glass, are mixed and then heated in a furnace. The molten glass is then passed through a spinner, which creates a multitude of thin glass fibers. These fibers are sprayed with a binder and then formed into a mat. The mat is cured in an oven, which hardens the binder and gives the glerull its shape and strength.

Glerull is available in various forms, including batts, rolls, and loose-fill. Its performance can vary depending on its density and thickness. It is generally considered a safe material to handle, though it is recommended to wear protective clothing and a mask when working with it to avoid skin irritation and inhalation of fibers. Glerull is a cost-effective and widely available insulation solution.
