    High Performance Insulation for
    Masonry Block & Tilt Slab Walls

    EXPOL FastLine is a high-performance, graphite-enhanced expanded polystyrene (EPS) insulation board specifically engineered for masonry block and tilt slab wall applications in New Zealand construction.

    With an R-value of 2.0 at just 60 mm thickness, EXPOL FastLine delivers outstanding thermal performance in a slim, space-efficient profile—making it a cost-effective solution for commercial, industrial, and residential projects.

    Designed to support compliance with updated H1 Building Code requirements, EXPOL FastLine enables fast, straightforward installation while improving overall wall system performance.

    Manufactured for long-term durability, EXPOL FastLine will not sag, slump, or degrade over time, ensuring consistent insulation performance for the life of the building.

    Important: Do not store in direct sunlight. Exposure may damage the product and void the warranty.
