Loose Glasswool

Glass wool is an insulating material made from glass fibres. These fibres are arranged using a binder into a texture similar to wool. This process traps small pockets of air between the glass, which give the final product its superior thermal insulation properties. Glass wool can be a loose-fill material, blown into attics, or together with an active binder, sprayed on the underside of structures, sheets, and panels that can be used to insulate flat surfaces such as cavity wall insulation, ceiling tiles, curtain walls, and ducting.
