Hidden Off-Gassing: Could Your Walls Be Impacting Your Health?
Creating Healthier Indoor Environments with Durra Panels Passive VOC Neutralisation
The Air We Breathe
People now spend close to 90% of their time indoors, yet many modern buildings unintentionally trap invisible chemical pollutants known as Volatile Organic Compounds (VOCs). These compounds can build up indoors at concentrations 2–10 times higher than those found outside.
VOCs are a large group of carbon-based chemicals that easily become airborne at room temperature. They are commonly released from construction materials, furniture, finishes, and everyday household items (Department of Climate Change, Energy, the Environment and Water).
Why This Matters for Health
Exposure to VOCs and indoor air pollutants has been associated with a variety of health concerns:
- Short-term effects: Eye, nose, and throat irritation, headaches, dizziness, and fatigue
- Long-term effects: Potential damage to the liver, kidneys, and central nervous system, along with respiratory issues
Poor indoor air quality is also linked to “sick building syndrome,” where occupants experience persistent symptoms related to time spent inside a building.
Today, responsible design goes beyond minimising harm — it calls for materials that actively contribute to healthier indoor environments.
How Durra Panel Helps Purify Indoor Air
Durra Panel works through adsorption, a natural process where airborne particles are captured and retained on a surface, preventing them from circulating back into the air.
Natural Straw Structure
At its core, Durra Panel is made from compressed wheat straw. On a microscopic level, this material offers powerful performance:
- Micro-porous structure: Millions of tiny pores capture airborne molecules
- Natural molecular attraction: Plant fibres draw in and slow VOCs
- Long-term containment: Pollutants are trapped and held within the panel structure
Biochar Integration (Biochar Finish Panels)
For projects focused on enhanced indoor air quality, Biochar-integrated panels provide advanced passive purification:
- Extremely high surface area: Over 500m² per gram
- Fast-acting performance: Targets emissions from paints, fuels, and solvents
- Optimised for peak exposure: Ideal during new builds and fit-outs when VOC levels are highest
This added layer significantly improves the panel’s ability to reduce airborne contaminants, particularly during high-emission periods.
Proven Results: Independent Testing
Durra Panel performance is backed by independent testing conducted over 137–139 hours in controlled chamber conditions. This allowed both short-term adsorption and long-term VOC reduction to be analysed.
Three test conditions were assessed:
- No panels
- Natural Finish Durra Panels
- Biochar Durra Panels
A variety of common indoor VOCs were introduced at both high and low concentrations and monitored over time.
Key Outcomes
- Effective VOC reduction: Natural Finish panels significantly lowered airborne chemical levels
- Enhanced performance with Biochar: Faster and more comprehensive pollutant reduction
- Consistent results: Effective across a wide range of VOC types
- Permanent capture (no rebound): Once absorbed, VOCs remain locked within the panel
At end of life, the panels return to the earth, where microorganisms break down the straw matrix and safely convert trapped VOCs into harmless by-products such as carbon dioxide, water, and inorganic compounds — completing a fully non-toxic lifecycle.
These results confirm that Durra Panel delivers continuous, passive VOC adsorption, not just temporary air quality improvement.
A Smarter Solution for Every Project
Durra Panel introduces a level of performance that traditional building materials cannot match — whether you’re designing, building, or living in a space.
For Homeowners & Occupants
- Health and wellbeing: Supports healthier living environments, particularly for children and the elderly
- Reduced symptoms: Helps minimise common issues linked to poor air quality, such as headaches, irritation, and fatigue
For Builders & Developers
- Market advantage: Offer homes with built-in “active health” benefits
- Simplified compliance: Improve indoor air quality without complex HVAC systems or added costs
- Future-ready design: Align with increasing demand for low-toxicity, carbon-negative materials
Modern clients are no longer focused solely on aesthetics — they want buildings that actively support their health. Durra Panel shifts air quality from a secondary concern to a core design feature.
More to Come
Initial independent testing has confirmed Durra Panel’s strong ability to remove airborne pollutants. Ongoing long-term VOC studies are underway, with a comprehensive independent report to follow.
Durra Panel combines high-performance construction with built-in air quality improvement.
