Glasswool Insulation / Fibreglass Insulation

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 Australia and world wide.

Glass wool insulation is produced in rolls or in slabs, with a variety of different thermal and mechanical properties to meet the complex needs of modern construction methods.

In addition to having excellent insulation properties, glasswool insulation is also non combustible and very durable.

Glasswool Insulation is soft to the touch but retains a high tensile strength and resembles a mass of matted wool fibres, hence the name.

Although exposure and handling of glasswool insulation can cause some mild irritation to the skin, this is purely mechanical in nature as an offshoot of the fibres strength and there is no evidence to suggest any long term skin irritation once the loose fibers are washed. Glasswool and rockwool do not cause dermatitis or any other skin conditions.

Today, glasswool used in Australia must be manufactured from what are called 'Bio Soluble Fibres', which essentially means they have a lower bio persistence than regular dust and have been extensively researched and found to have no adverse affect on health.
