Insulmax Blown Fibre Insulation or mineral wool insulation is the preferred product our contractors use for existing underfloor cavities. Manufactured by melting and spinning inert minerals to form fine strands, these strands are then milled to form a very high performing blown micro fibre insulation.

An inert water repellent agent is then added which makes the product very resistant to the absorption of liquid water. The products used will not wick water and are a fully breathable. The milled micro fibres are able to be blow installed via small holes. The fineness of the micro fibres also contributes to its exceptional thermal insulation properties and allows it be densely packed into underfloor cavities where access is difficult.

At installed densities the mineral wool & existing underfloor insulation products our preferred suppliers use, have been tested to provide an insulation rating of R2.8 /100mm and has been given the highest rating of non combustibility and it’s rated settling is S1 (less than 1% or unmeasurable). Ask for product technical statements during assessments .

All installed by qualified, experienced, professional installers to local TA code requirements.
