MegaForm ICF Systems

All MegaForm blocks are manufactured from high-quality EPS, with 65mm of EPS on each side, achieving an R4 wall insulation rating.
Our system comes in multiple series with adjustable inserts, allowing the internal concrete core size to be customised. This flexibility gives architects the freedom to design with creativity, from bold shapes and varied wall thicknesses to integrating unique structural features, without being restricted by standard concrete dimensions. For engineers, the adjustable core ensures the system can be tailored to meet precise structural requirements, whether for residential builds, high-performance commercial projects, or specialised architectural designs. MegaForm combines design freedom, thermal performance, and structural strength in one efficient package

THERMAL INSULATION

Expanded Polystyrene (EPS) in MegaForm blocks delivers durable strength and reliable thermal performance that lasts the lifetime of the building. Its stability means the insulation won’t shrink, settle, or lose effectiveness over time.

A key advantage of the MegaForm system is continuous insulation — the blocks create a seamless thermal barrier with no gaps or breaks. This continuous insulation is a crucial part of achieving a well-constructed, energy-efficient home, reducing thermal bridging and improving overall building performance.

With an impressive R-value of 4, MegaForm blocks exceed New Zealand energy efficiency standards. This high level of insulation can reduce heating and cooling energy consumption by 40–70% compared to typical code-minimum construction, helping to lower energy bills and reduce environmental impact.

By combining continuous thermal efficiency with structural integrity, MegaForm supports sustainable, comfortable buildings that perform year-round.

MegaForm blocks are manufactured using an environmentally friendly, flame-retardant EPS. This specially formulated material self-extinguishes as soon as the ignition source is removed and slows the spread of fire when exposed to direct flames. Combined with the concrete core, this results in exceptionally high fire-resistance ratings

In addition to superior fire protection, MegaForm walls offer outstanding acoustic performance. With a Sound Transmission Class (STC) rating above 55, our system significantly reduces sound transmission, creating quieter, more comfortable living and working environments. This makes MegaForm an ideal choice for multi-unit developments, where noise control is essential

MegaForm blocks are filled with reinforced concrete, providing unmatched structural integrity. Steel-reinforced concrete remains the gold standard in strength and durability, and MegaForm meets or exceeds all New Zealand and Australian building standards.

Our system is particularly well-suited for earthquake-prone areas and challenging terrain such as hill sites, offering superior resistance and safety where it matters most.

MegaForm blocks come in a variety of sizes, making them adaptable for all building types from single-story homes to multi-story commercial structures and flexible enough to meet specific architectural and engineering design requirements.

STRENGTH

MegaForm blocks are supplied as individual units in a range of widths, ready to be assembled on site for maximum versatility across all types of construction projects. Onsite assembly is especially beneficial when working with complex steel reinforcement.

Each block’s interior features a tongue and groove locking system to create a superior bond between the polystyrene and concrete. In addition, the tongue-and-groove edge design ensures precise alignment, minimises material waste, and speeds up installation without compromising accuracy.

From new homes and renovations to multi-storey buildings, apartments, swimming pools, retaining walls, and even bunkers, MegaForm delivers the flexibility to suit virtually any project.
