Quality materials

Constructed with quality materials and sustainability in mind, most of our Modul homes are rated at 6 Homestar by the Green Building Council – significantly above the New Zealand Building Code, which requires a 4 Homestar rating to comply.


As manufacturing offshore creates new challenges, quality management is an integral part of the Modul process. Here in New Zealand, Modul homes receive the government-approved Multiproof consent, while SGS New Zealand monitors quality throughout the manufacturing process – from materials supply to construction and compliance.

SGS is the world's leading inspection, verification, testing and certification company, and is also responsible for auditing the integrity of Modul manufacturer's ISO 9001, ISO 14001 and OHSAS 18001 certificates.

An independent audit was carried out using SMETA audit methodology – a compilation of best-practice audit techniques designed to help auditors conduct high-quality audits. SMETA ensures responsible business practice by both Modul and the manufacturer, covering labour, health and safety, environment and business ethics.

What's Modul made of?

Modul homes feature floor-to-ceiling windows, top notch double-glazing and are made from the same solid steel as shipping containers – and shipping containers withstand repeated ocean voyages and overland journeys, so they are incredibly durable. 

Let's take a look at some of the key elements in the structure of a Modul home.

Solid steel comfort

At the heart of Modul’s design is a heavy-duty structural steel frame that provides the homes with strength and rigidity. The ‘Mild steel’ used in a Modul home is 1.5mm thick, three times thicker than a standard new steel roof in New Zealand. The independent certification of the welding and assembly means that Modul fully complies with New Zealand’s high standards – and this translates into a building structure that performs to the highest standards, even in powerful seismic events.

High-performance glazing

Modul’s utilises a double-glazed, thermally broken, argon-fill window system. This provides best-in-class thermal and acoustic insulation, ensuring the home is not just warm and dry, but also very quiet. New construction technology allows the windows to run from floor to ceiling, without the need for a lintel. Full-height glazing invites sunlight deep into the interior of the home, making it feel bright and airy, even in winter.

Multi-layer insulation system

Modul combines the latest insulation technologies and materials in a unique multi-layer system to deliver outstanding thermal, moisture and acoustic performance. The continuous steel envelope design provides an impervious airtight barrier against water, sound and weather. These excellent thermal properties ensure that most Modul homes achieve a minimum of 6 stars via the New Zealand Homestar energy rating system.
