Cellulose Fiber

Cellulose Fiber is a loose fill insulation that can be used in the ceilings of new houses or retro-fitted to older houses. It's made from recycled newsprint, so it's very environmentally friendly.

Our cellulose fiber is non-irritant, non-toxic, and has one of the highest fire ratings. Cellulose Fiber is vermin proof and has an excellent R-value. R-value is the measure of thermal resistance. The higher the value the greater the thermal resistance. Because it is loose fill, it does not have thermal bridging that occurs with batts, thus not reducing the thermal value. It meets Building Code of Australia standard AS/NZS 4859.1 and is one of the only insulations to have the Australian Standards 5 ticks.  Talk to us about how this product can fill your insulation needs.

Granulated Wall Cavity Fill

We use Rockwool Granulated Wall Cavity Fill, a CSR Bradford product as our 'Gold Seal' product in this class. It can be used in all wall applications including weatherboard, brick (veneer or cavity), or clad houses.

Rockwool Granulated Wall Cavity Fill by Bradford

It is silicone treated to repel moisture thus not allowing capillary action or the transfer of moisture to the plaster. This treatment also allows the walls to "breathe" in that atmospheric moisture that accumulates in the home can still escape through the walls without any problems.
