Overview

Non-combustible White Faced Insulation

Non-combustible as per NCC 2022, Clause C2D10(6)(g), IROCK PLUS soffit insulation is a thermal and acoustic insulation material comprising of a rigid stonewool insulation board bonded to either a non-combustible FIRESPAN facer or a pure aluminium facer. Providing an attractive white finish and high-density 10 KN/m2 compressive strength, IROCK PLUS is the safe and responsible choice for all under-slab soffit applications such as car parks, high-rise apartments and health buildings. Compared to alternative materials, IROCK PLUS produces much less smoke in a fire scenario and has superior ageing performance 


Non-combustible

IROCK PLUS is deemed non-combustible when tested to AS 1530.1 and AS 1530.3 in accordance with NCC 2022, Clause C2D10(6)(g) meaning it an be used wherever a non-combustible material is required.


Moisture Resistant

Although not suitable for permanent immersion or exposure to drenching, IROCK PLUS insulation board's thermal performance will not be adversely affected by condensation or contact with liquid water.


Excellent Acoustic Performance

Along with excellent fire safety and thermal performance, IROCK PLUS also provides an excellent acoustic performance of NRC >1.0 in accordance with ISO 354-2006, an ideal solution for plant-rooms.


Light-weight & Attractive

Not only are IROCK PLUS insulation boards very lightweight (only 100kg/m3), they also offer an attractive white finish ideal for exposed under-slab soffit applications such as shopping centre car-parks.


Cost-Effective

With a nominal thermal conductivity of 0.036 W/mK and a very economical price-point, IROCK PLUS offers excellent thermal efficiency for minimal upfront cost along with life-cycle energy savings for the building.


Environmentally Friendly

Largely manufactured from recycled materials and natural rock, IROCK PLUS is environmentally friendly as an initial product. It also offers numerous environmental benefits in application as thermal insulation.


NCC 2022 Compliant

NCC 2022 Clause C2D10 specifically requires all components of external walls including cladding, insulation and framing to be non-combustible and IROCK PLUS is one of only a few materials that meet this criteria.


Superior Ageing Performance

Unlike low density batts which tend to slump in vertical applications or PIR and phenolic insulation which lose thermal performance over time, IROCK PLUS is anti-slump and has excellent long-term ageing performance.

*Important Note: The standard IROCK PLUS facer is made from a fibre-glass fabric which forms a non-rigid white finish to the face of the insulation. It will not be perfectly smooth or flat and will indent at fixing points as per photos in the image gallery. If a smoother, more uniform finish is preferred we can also supply IROCK PLUS with a white 0.5mm thick pure aluminium facer which offers much superior aesthetics.
