Hempcrete: The Ultimate Fireproof Building Material for Australia
Hempcrete: A Natural Solution for Fire-Resistant Construction
As Australia faces increasing threats from bushfires, choosing the right building materials is critical for safety and peace of mind. Hempcrete, an innovative building material made from hemp hurd mixed with lime, is proving to be a game-changer for fireproof construction. This eco-friendly and sustainable material not only offers superior insulation and breathability but also stands out for its exceptional fire resistance.
Proven Fire Resistance: Hempcrete’s Fire Testing Results
In a real-world fire test conducted by the Australian Hemp Masonry Company, a 200mm thick hempcrete wall, rendered with 10mm of hemp-lime plaster, was exposed to intense fire conditions. The test was designed to replicate a bushfire scenario, simulating ember attacks with a 600mm high flame from burning timber placed directly against the wall.
Despite being subjected to flames for over an hour, the hempcrete wall showed no signs of damage. Laboratory tests further confirmed its fire-resistant properties, with the internal temperature remaining below 100°C—well below the ignition point of conventional building materials like pine wood, which ignites at over 400°C.
But Don't just take our word for it, here's what the Australian government has to say;
"Hempcrete is inherently fire resistant. Testing with direct flame exposure showed no combustion with minor surface charring after exposure to direct flame for over 1 hour" | Yourhome.gov.au
Compliant with Australian Fire Safety Standards
Hempcrete is fully compliant with AS 3959, the Australian Standard for Construction in Bushfire-Prone Areas. When used in walls that are 200-300mm thick, with a 10mm lime render, hempcrete achieves a Bushfire Attack Level (BAL) rating of up to BAL 40, making it suitable for regions at high risk of bushfires. This means that properly constructed hempcrete walls can withstand severe fire exposure while keeping occupants safe.
Why Choose Hempcrete for Your Building Project?
- Natural Fire Resistance: Unlike conventional building materials, hempcrete does not release toxic fumes when exposed to fire.
- Sustainable and Eco-Friendly: Hempcrete is made from renewable resources and is fully biodegradable.
- Superior Insulation: Provides excellent thermal regulation, keeping homes cool in summer and warm in winter.
- Moisture Resistant: The lime component naturally prevents mold and dampness, contributing to healthier indoor air quality.
