Glasswool is a type of insulation material that is made from recycled glass. It is commonly used in buildings to insulate walls, ceilings and roofs to keep the interior of the building warm in the winter and cool in the summer. Glasswool is also used in a variety of other applications, such as soundproofing and as a filter material. Because it is made from recycled glass, glasswool can be considered a sustainable material.
Glasswool is made by melting recycled glass and spinning it into fine fibres which are then formed into insulation batts or rolls. The melted glass is mixed with other materials, such as boron or alumina, to give the glasswool its insulation properties. The process of making glasswool is similar to the process used to make other types of fiberglass insulation.
There are many different types of insulation materials available, each with its own unique properties and characteristics. Comparing glasswool to other types of insulation can be difficult because it depends on the specific application and the performance criteria that are important in that situation. In general, glasswool is a sustainable insulation option that can provide good thermal insulation and soundproofing properties. It is also relatively easy to instal and can be used in a variety of different applications. However, it is not as effective as some other types of insulation at preventing the passage of moisture, so it may not be the best choice in damp or humid environments.
Glasswool can also be irritating to the skin and respiratory system. It is important to use protective gear, such as gloves, masks, and goggles when handling glasswool to avoid irritation. Additionally, glasswool products can be flammable, so it is important to follow the manufacturer's instructions when installing it to ensure that it is used safely. Glasswool itself is non-flammable, but the wrapping, resin binder, and some facings may burn.
