pdfInsulpro Friction Fitted Airlay Product Sheet
Friction fitted Airlay Insulation
To measure the in-situ thermal performance of a typical wall insulated system using
InsulPro R2.0 medium density, airlay polyester insulation.
Some insulation in New Zealand doesn’t always retain its full R-value and thermal
performance due to compression, creasing, gaps and slumping (typical of lower density
insulation) after installation. InsulPro developed friction fitted airlay products, which
are unique in that the fibres are completely randomised rather than layered, enabling
a product that supports itself without creasing when squeezed between floor joists
and wall studs/dwangs.
InsulPro’s medium density, airlay products are designed to give a quicker, superior
quality installation, therefore a higher R-value and thermal performance.
This means a higher systems R-value can be achieved using a lower R-value product
combined with quality product installation.
InsulPro medium density, airlay polyester pads are designed to be squeezed between framing elements in timber or timber
• Friction fitted between framing elements without tucks, creases or gaps to maximise thermal performance
• Designed to support itself within the framing elements for the lifetime of the building
• With its greater density, it won’t sag or slump over time
• Maintains its nominal thickness
• Carries a 50 year product manufacturers warranty
• Is not affected by moisture
• Chemical Free - no formaldehyde or pesticides
• Is easy to cut to size, making it faster for installers to
achieve a high quality install
InsulPro R2.0 medium density, airlay product was installed in a
standard 90mm timber wall cavity, with 10mm plasterboard lining,
and direct fixed weatherboard cladding.
Measurements were taken every 10 seconds over a two week period
during winter 2013. The results were then independently verified by
an accredited testing laboratory.
Over the two week test period, the R-value of the wall system was measured and recorded.

The average recorded R-value was R2.7
The thermal resistance (R-value*) of the wall system installed with InsulPro R2.0 medium density, airlay product was measured
at R2.7 - well in excess of the nominal R2.0 insulation R-value and well in excess of the New Zealand Building Code requirements
for all New Zealand Climate Zones.
The unique properties of InsulPro’s R2.0 medium density, airlay product help it retain its nominal thickness, achieve a
high quality, friction fit without undue compression, gaps, tucks or creases. All of these qualities ensure thermal performance
is maximised. InsulPro are so confident the full potential of the insulation is realised and sustained over the long-term of the
building, we provide a 50 year manufacturers warranty.
We believe, when InsulPro’s R2.0 medium density, airlay product is installed in timber framing with plasterboard lined walls,
it will cost effectively contribute to a level 6 Homestar rated home.
* NZS4246 define R-value as:
R-values. The value of thermal resistence of a building element (e.g: wall, floor or roof) which is the sum of the surface resistances on each side of a building
element and the thermal resistances of each component of the building element including any cavities in the element. It is determined by calculation or by
measuring the temperature difference between the internal air on one side and the external air on the other side of a building component, when there is a
unit heat flow in unit time through unit area using internal and external conditions considered as typical for buildings (m oC/W)
Creating better environments
• InsulPro insulation helps to create more comfor table and healthy liv ing spaces.
• InsulPro thermal produc ts contain recycled polyester fibres. T he recycled
fibre used by InsulPro comes 100% from recycled plastic bottles.
• Recycling plastic protects the environment by keeping the carbon content
locked up in the polyester fibre and reducing landfill waste.
• InsulPro insulation is made in a near zero waste production process, and
is fully recyclable.
