Glasswool Craft Paper Coated Roll

Glasswool Insulation or Fibreglass Insulation  as it is also called, is a fibrous bulk insulation made from millions of tiny fibres of glass that are arranged into a blanket through the use of a binding agent. The process traps thousands of little pockets of air between the fibres. It is these pockets of air that give glasswool insulation its excellent insulating properties.  Because glasswool insulation has such good insulating properties and can be produced at very low cost, it is the most widely used insulation material in the construction industry in world wide.
