IROCK

Non-combustible Facade & Cavity Insulation

IROCK non-combustible facade & cavity insulation is a thermal and acoustic stonewool insulation material widely used in both external and internal wall applications that require high levels of fire safety and thermal performance. IROCK is manufactured by spinning a molten mixture of natural rock materials and other additives to create fine wool-like fibres which are bonded together using a thermoset resin to form a rigid insulation board. Compliant with NCC 2019 & NCC 2022, IROCK offers excellent long-term ageing performance and superior resistance to water absorption compared to other common insulation materials.

Non-combustible

IROCK is deemed non-combustible when tested to AS 1530.1 meaning it is compliant for use in external walls and cladding systems where insulation is required to be non-combustible for buildings of types A & B construction.

Moisture Resistant

Although it is not suitable for permanent immersion or exposure to drenching, IROCK 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 also provides an excellent acoustic performance of NRC >1.0 in accordance with ISO 354-2006 providing an ideal solution for party walls.

Light-weight & Ultra-durable

IROCK non-combustible insulation boards are both very lightweight and highly durable for safe hassle-free handling onsite and they can be easily cut and formed to suit almost any application.

Cost-Effective

With a nominal thermal conductivity of 0.036 W/mK and a very economical price-point, IROCK 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 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 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 is anti-slump and has excellent long-term ageing performance.
