Ceiling Insulation

Types of Insulation

  • Fibreglass Batts: Are glass melted at high temperatures and then formed into a matt of fine fibres.
  • Rock wool Batts: Are rock melted at high temperatures.
  • Polyester Batts: Fine strands of polyester.

  • These types of insulations only have air locks between the fibres.

    Note: Its the airlocks that does the insulating. The heat can't keep jumping through a series of air-spaces. Air locks retard the transference of heat, the more airlocks the less heat that gets through. For example with the fiberglass batt insulation glass is actually a conductor, its only the air locks between the fibres that are doing the insulating.

    • Wool Batts: Natural wool.

    Wool being a natural Insulator has air locks within and between its fibres which means you don't require the same thickness to match the insulating effect of the above synthetic types of insulation. It is significantly more expensive and not unattractive to vermin. All the above types of insulation are placed in by hand making it extremely difficult to achieve Gap Free Coverage


Treated Cellulose Fibre: Is finely milled newspaper which is pulverized to give a fine fluff. Since paper is flammable, a fire retardant such as a mixture of Borax and Boric Acid (naturally occurring chemicals, less toxic that table salt) is added by the manufacturer.
Its very name Cellulose means that it has tiny air cells within the fibres like human hair fur wool and feathers which are all natural insulators. WHEN ITS PUMPED IN ITS FLUFFED SLIGHTLY so that it also has airlocks between the fibres. So it has airlocks within and between the fibres and by using the pumped in installation method means that Gap Free Coverage can be achieved.
