Isomax X300 XPS 70mm – Built for Performance and Reliability

Isomax X300 XPS 70mm insulation panel offers a robust solution for modern construction needs. Designed with precision, it delivers consistent thermal protection, moisture resistance, and structural strength across a wide range of applications.

Isomax X300 XPS 70mm – Superior Thermal Efficiency

Thanks to its closed-cell extruded polystyrene (XPS) composition, the panel actively resists moisture and retains its insulating properties in harsh conditions. With a thermal conductivity of 0.0337 W/mK, it significantly reduces heat transfer, helping to lower energy costs and improve comfort. Its R-value of 2.1 makes it suitable for slabs, cavity walls, and roofing systems.

Isomax X300 XPS 70mm – Easy Installation and Handling

You can install the Isomax X300 quickly and efficiently. Its lightweight design allows for easy transport and handling, while standard cutting tools make shaping simple. As a result, installation time decreases and overall productivity improves. The square edge finish and skin-on surface also ensure a clean, professional look.

Strength That Supports Heavy Loads

The panel offers a compressive strength of 300kPa, making it ideal for load-bearing applications. It performs reliably under pressure, whether used beneath concrete slabs or in rooftop systems. Builders trust its durability to maintain structural integrity over time.

Environmentally Responsible Choice

Isomax X300 supports sustainable building practices. It contains no ozone-depleting substances, emits low or no VOCs, and is 100% recyclable. Therefore, it aligns well with green building standards and environmentally conscious projects.

Certified for Compliance and Safety

The panel meets key industry standards, including AS/NZS 4859.1 for thermal performance and AS/NZS 1530.3 for fire resistance. It also complies with the Building Code of Australia (BCA), ensuring peace of mind for builders and specifiers alike.

Conclusion: A Smart Investment in Long-Term Performance

Whether you’re insulating a basement, rooftop, or wall cavity, the Isomax X300 XPS 70mm panel delivers lasting performance, energy efficiency, and environmental benefits. Choose Isomax for insulation that works today and endures tomorrow.
