75mm spun glass fibre foil faced building blanket insulation with a laminate of reflective foil with an actual R-Value of 1.7
PolyX 75 Building Blanket combines the thermal efficiency of spun glass fibre with a laminate of reflective foil which not only further enhances the thermal efficiency of the system but also serves to act as a dust and moisture barrier. This 75mm foil faced blanket insulation provides an actual R-Value of 1.7.
PolyX 75 is intended for both thermal and acoustic applications. It is made from highly resilient, inorganic glass fibres manufactured by spinning molten glass, containing up to 65% recycled content and bonded together using a thermosetting resin.

PolyX 75 Application
Designed for application under metal, fibre cement, and concrete roof cladding PolyX 75 blanket eliminates the problems associated with condensation build up on the underside of the roof cladding. The reflective foil face faces down toward the air space under the roof and prevents airborne moisture from reaching the surface of the roof cladding.
PolyX 75 also performs as an acoustic insulative barrier. It reduces noise from outside the home, such as rain and from within the home by absorbing reverberant noise. PolyX’s bulk insulation blanket is made from non-combustible fibres and meets the BAL requirement for metal clad roofs in bushfire areas.
What is the fire performance of PolyX 75?
PX75 has a Fire Assessment Classification
Group 1 Tested in accordance with AS/ISO 9705 & AS5637.1.
Bushfire Attack Level of PolyX 75 is suitable for BAL 0-40 as outlined in AS 3959 for metal roofs. The glasswool
component of PolyX 75 Blanket is classified as non-combustible in accordance with AS1530.1 and is suited for sealing ember entry points at ridges, valleys and fascias to meet NCC requirements for metal clad roofs in bushfire areas. The reflective foil facing component satisfies the NCC flammability index requirement of ≤5.
In areas where BAL-FZ is a requirement higher density glasswool or mineral wool is required and available upon request.
What is the thickness of PolyX 75?
Total thickness = 75mm.
What is the actual R-value of PolyX 75?
PX75 has an actual R-Value of 1.7.

PolyX 75 Installation Requirements
In the event of PolyX 75 Blanket becoming wet, it should be dried prior to installation to obtain maximum performance and prevent damage to other building elements. PolyX 75 absorbs less than 0.2 % moisture by volume when exposed to environmental conditions of 50°C and 95% relative humidity for four days.
