The Silent Off-Gassing Crisis: Are Your Walls Working Against Your Health?

Humans now spend around 90% of their time indoors, yet modern interiors often trap invisible toxic chemical vapours called Volatile Organic Compounds (VOCs), which can accumulate at levels 2–10 times higher than outdoors.

Among the most significant of these pollutants are Volatile Organic Compounds (VOCs), a broad group of carbon-based chemicals that easily evaporate at room temperature and are commonly emitted from building materials, furnishings, and everyday household products (Department of Climate Change, Energy, the Environment and Water).

The Impact on Wellbeing:

Exposure to VOCs and other indoor air pollutants has been linked to a range of health effects:

• Short-term: Irritation of the eyes, nose, and throat; headaches; dizziness; and fatigue
• Long-term: Potential impacts on the liver, kidneys, and central nervous system, as well as respiratory conditions

Poor indoor air quality is also associated with “sick building syndrome,” where occupants experience ongoing symptoms linked to time spent within a building.

Responsible building design now requires materials that don’t just “do no harm,” but actively improve the environment.

Durra Panel uses the science of adsorption, a process where airborne molecules are captured and held by a surface, preventing them from recirculating.

Natural Straw Structure

At the core of Durra Panel is compressed wheat straw. At a microscopic level, this natural fibre is a powerhouse:

• Micro-Porous Architecture: Millions of tiny pores trap passing molecules.
• Molecular Attraction: Plant fibres naturally draw in and slow down VOCs.
• Permanent Capture: Contaminants are trapped and locked away within the panel’s dense structure.

Biochar Integration (Biochar Finish Panels)

For healthy living environments, our Biochar integrated panels are the gold standard in Passive air purification technology.

• Massive Surface Area: A single gram of biochar can have a surface area of over 500m2.
• Rapid Response: Neutralises paints, fuels, and industrial solvents.
• Peak Performance: Ideal for new fit outs where VOC spikes are most aggressive.

This enhances the panel’s ability to reduce airborne chemicals, particularly during periods of higher exposure.

We don’t just claim better air; we measure it. Testing was conducted over 137–139 hours under controlled chamber conditions, allowing for detailed analysis of both short-term adsorption performance and long-term VOC reduction behaviour.

Three scenarios were compared:

• No panels
• Natural Finish Durra Panels
• Biochar Durra Panels

A range of VOCs commonly found indoors were introduced, and their concentrations at high and low ranges were measured over time.

Key Findings:

• Proven VOC Neutralisation: Natural Finish panels significantly lowered the concentration of airborne chemicals, creating a measurable shift in air purity.
• The Biochar Advantage: The Biochar Finish delivered a superior reduction rate, neutralising pollutants faster and more comprehensively.
• Broad-Spectrum Efficacy: Performance remained consistent across a diverse range of VOC types.
• Permanent Capture (No Rebound): Testing confirmed that once VOCs are adsorbed, they are locked within the panel’s core. Once the panel reaches end of life and is returned to the earth, soil microorganisms break down the straw matrix and naturally biodegrade the trapped VOCs, converting them into harmless end products like carbon dioxide, water, and inorganic compounds, completing a full, non-toxic lifecycle.

The test results demonstrate that Durra Panel provides sustained, passive VOC adsorption, not just a temporary fix.

Whether you are living in a space or building it, Durra Panel adds a layer of performance that other building materials cannot match.

For Homeowners & Occupants

• Wellness Impact: Proactively protects families, especially children and the elderly, who are most sensitive to airborne VOC irritants.
• Symptom Relief: Significant reduction in common “Sick Building Syndrome” triggers, such as itchy eyes, morning headaches, and respiratory fatigue.

For Builders & Developers

• Market Differentiation: Lead the market by offering “Active Health” homes. It’s a powerful selling point for wellness-focused buyers.
• Reduced Complexity: Achieve high air-quality ratings without the inflated costs of specialised HVAC filtration or sensors.
• Future Proofing: Address the growing regulatory and consumer shift toward non-toxic, carbon-negative building materials before it becomes mandatory.

Why This Matters Now Modern clients are no longer just asking about how a building looks; they are asking how it performs for their health. Durra Panel moves air quality from an “afterthought” to a structural reality.

Initial independent testing has confirmed Durra Panels strong effectiveness in removing airborne toxins. We are continuing a program of long-term VOC testing and will provide an independent report once the extended testing has been completed.

Durra Panel integrates high performance and air quality control into one advanced building solution.
