Frequently Asked Questions
Is Helix suitable for all climates?
Absolutely. Whether you’re building in a coastal environment, a high-humidity region or a bushfire-prone zone, Helix has been engineered specifically for Australian conditions – so it can handle whatever the climate throws at it.
Can I choose the colour of my panels?
Yes. Helix offers a curated palette of architectural tones through Dulux, giving you the flexibility to achieve the right look for every project – from contemporary neutrals to bold statement finishes.
Is Helix fire-rated?
Yes. Helix panels are non-combustible and suitable for use in BAL-rated zones, giving builders and homeowners confidence when specifying in bushfire-prone areas.
Can any builder use Helix?
Yes. Helix has been designed to be compatible with common framing systems, and comprehensive installation guidance is provided – making it a straightforward choice for builders of all experience levels.
What maintenance does Helix require?
Very little. The Dulux-accredited finish is designed to resist fading, flaking and cracking over the long term, meaning a simple rinse is typically all that’s needed to keep Helix panels looking their best.
