Insulwool® Blanket Wool


Insulwool Blanket consists of coloured sheep’s wool sourced from New Zealand wool product manufacturers blended with up to 30% polyester.   It is supplied as a blanket ready to roll out over ceiling joists or fitted under or between floor joists. Rolls are cut to length when fitting to wall framing cavities.

Insulwool Blanket insulation is manufactured to fit between standard framing spacings. Special runs can be manufactured to order , for example, a roll width of up to 2 m is possible.

Individual Insulwool® Blanket packs are labeled to identify the specific R-value, coverage per pack in m2, material width, unit number or length of material, nominal thickness, minimum weight and date of manufacture.

Insulwool® complies with the insulation standard AS/NZS 4859.1.
