Loose Fill Characteristics

Complete coverage achieved because of "fluid" nature of materials
Thermal resistance is a function of the blown density and thickness of product installed
Installed generally into ceiling space by being pneumatical blown or pumped
A good installation job requires:

Full coverage, no thin spots

Barriers (batts or foil) around fans, down lights, manhole and flues

Installation needs care to ensure complete coverage of material at correct blown density
Totally dependent on the quality of installation to achieve the R value
To achieve Australian Standard recommended R Values generally ceiling joists have to be covered
R3.0 is the suggested maximum level of insulation, as weight loading on the ceiling starts to become a factor, (100mm thickness of products can weigh 3.5 - 5.0 kgm2)
Prone to thickness changes due to natural air movement in ceiling space unless surface is bonded
Barriers need to be installed to prevent loose fill insulation falling down wall cavities, face brick walls, exhaust fans etc
Some loose fill insulation readily absorbs water increasing the weight on the ceilings
Should only be used on flat ceilings, other than granulated rockwool

This very effective product can be used on flat ceilings and in raked ceilings.
The base material is from rockwool batts
The fibrous structure ensures material clings together and will not readily move around.

Cellulose Fibre Loose Fill

We offer product manufactured Australian Standard 2462
Made from recycled newspapers
It has fire retardant chemicals (Boric Acid and Borax) added to the material, 20% by weight.

A special water repellent grade of granulated rockwool is used for cavity wall insulation
An effective way of insulating double brick walls
Allows cavity to "breathe" but not "wick" moisture across the cavity by capillary action.
