Glass Wool Insulation

Glass wool is made from sand and recycled glass, limestone and soda ash. The glass is spun to form millions of fine fibres. A resin is used to bind the long fibres together to form a mat of material giving good tear strength. The density of the product determines whether the insulation is a lightweight quilt supplied in rolls, a flexible slab or a rigid slab, and it’s thermal insulation value. 

Applications include:

  • loft insulation
  • cavity wall insulation
  • sound insulation within partitions and floors

Other characteristics include:

  • Suitable for temperatures up to 230°C,
  • Typically includes 30 – 60% of post consumer waste,
  • A formaldehyde-free binder is available in some brands,
  • Reusable if in a suitable condition,
  • Recyclable,
  • Relatively low-density of material in use reduces overall environmental impact,
  • Inherently non-combustible and resistant to rot,
  • Emissions associated with the manufacture of glass wool - mostly in energy generation. UK emissions are within legally defined limits
