Wool Insulation

Wool Fibre Structure




The advantages that wool has as a versatile textile fibre derive from its complex physical and chemical structure. Wool is composed of more than 20 amino acids which form long chains, or polymers, of protein. Two different types of cells, the paracortex and the ortho-cortex, develop into a three-dimensional corkscrew pattern, or helical crimp, of great elasticity. The coiled springs of wool's molecular chains contribute to the fibre's resilience. The outer cuticle and epicotyl layers of fibre give wool its ability to shed water yet readily admit water vapour. The fibre's structure is one of great flexibility and adaptability to different environments.

Due to wool's intricate structure, it has two major advantages over manmade fibres – it breaths and traps air, giving higher thermal and acoustic ratings over other insulators. Wool can act as a buffer or stabilizer to reduce peak humidity levels and condensation – this has been confirmed in research conducted by the International Wool Secretariat.
About The Fibre

Natural Protection – Against Cold, Heat and Noise

For centuries, wool has protected sheep from extreme weather conditions, and has been used as insulation in Europe since the eighteenth century. Due to wool's intricate structure, it has two major advantages over manmade fibres – it breathes and traps air, giving higher thermal and acoustic ratings over other insulators.

When you install New Wool Insulation (Fire Retarded), you are installing a completely safe and effective Australian product, manufactured by a 100% Australian owned Company.


Why Wool?

Research by the CSIRO shows that wool performs better as an insulator. Wool is a natural, active fibre and traps large columns of air that provide high resistance to heat flow. Higgins Manufactures a wide range of Wool Insulation using Australian Wool. The embodied energy of wool is one of the lowest of all insulating materials - wool is one of the wonders of the world for insulating. Higgins Insulation manufactures a wide range of thermal and acoustic Insulation products using wool to suit individual requirements and budgets.

Moisture Resistance

Wool's moisture absorbing properties give it major thermal resistance advantages. Wool has the ability to shed water, yet readily absorbs and disperses water vapour. Wool has the ability to stabilize and reduce peak humidity and condensation levels. (International Wool Secretariat)

Maximum Service Temperature

Maximum Service Temperature is 90 Degrees Celsius. Higgins New Wool Batts were developed to suit temperatures normally occurring in domestic or commercial buildings.

Ceiling Batt Applications

Wool Ceiling Batts have been designed to provide efficient thermal and acoustic to the home owner and to commercial projects including project builders

Wool Ceiling Batts have been designed to reduce noise heat and cold and to reduce energy costs by keeping heat out and keeping winter warmth in during winter. Correctly installed Wool Batts will substantially decrease your air conditioning costs. The Wool Batts are supplied in two widths to suit standard domestic constructions:

  • 430mm wide to be placed between joists at .450mm centres.

  • 580mm wide to be placed between joists at .600mm centres

Wall Batt Applications

Wool Wall Batts have been manufactured to specific thickness so that correct thermal and acoustic rating can be achieved without the insulation making contact with the external walls.

Wool Wall Batts have been designed to reduce noise, heat and cold and to reduce energy costs by keeping heat out and keeping winter warmth in during winter. Correctly installed Wool Batts will substantially decrease your air conditioning costs. Wool Wall Batts will also reduce noise entering the home through external walls and the transfer of noise between internal walls. The Batts can be stapled or taped into position so that ventilation of the wall cavity is maintained.
