Rigid PIR Insulation Board

IBOARD rigid insulation board is composed of a closed-cell thermoset polyisocyanurate foam core with two reflective foil facings. Tested in accordance with AS/NZ standards to comply with BCA/NCC requirements in concealed applications, IBOARD rigid insulation is manufactured using CFC/HCFC-free blowing agents that have zero Ozone Depletion Potential (ODP). Providing superior fire safety and higher R-values from less thickness, IBOARD rigid insulation gives sustained thermal performance over time and is widely used in brick cavity, frame-wall and concealed soffit applications.  

Superior Fire Performance

IBOARD rigid insulation offers superior results than alternative products when tested to AS 1530.3, the relevant Australian fire standard for concealed wall and soffit applications.

Superior Ageing Performance

Due to it's outstanding resistance to moisture and excellent compressive strength, IBOARD rigid insulation offers much better thermal ageing performance than other products.

100% Non-corrosive

Unlike some other insulation products, IBOARD core material is 100% non-corrosive and will not cause corrosion issues if it comes in contact with structural steel or fixings.

Zero Formaldehyde

IBOARD rigid insulation contians zero traces of formaldehyde and it is fibre-free making it non-irritant to the skin, non-allergenic and safer compared to other products.

Higher R-value

IBOARD rigid insulation provides excellent thermal properties with one of the lowest thermal conductivity ratings of any insulation material on the market at 0.022 W/mK.

Environmentally Friendly

IBOARD rigid insulation is manufactured in Europe under strict quality control using only CFC/HCFC free blowing agents which have Zero Ozone Depletion Potential (ODP).

Clear Cavity Maintained

When IBOARD rigid insulation is used in wall cavity applications a clear cavity is still maintained making the cavity easily accessible for services such as electricity and water.

Micro Cell Technology

IBOARD core material has a much finer cell structure with extremely low water absorbtion compared to other products (<0.6%) so it's R-value is retained long-term and it is rot and mould proof.

*Does your project require Non-combustible materials?

If your project is required to be type A or B construction then all cladding, framing & insulation is required to be non-combustible. All the below cladding products are Deemed-to-Satisfy (DtS) non-combustible in accordance with NCC 2022, Clause C2D10 (Previously NCC 2019, Clause C1.9) and can be used anywhere a non-combustible material is required;
