Questions you might be asking.
THE MATERIALS
What are Nexa Modular Solutions homes made of?
98% organic, sustainably sourced materials. The system includes: structural timber frame, ultra-efficient wood-fiber insulation, airtightness membranes, triple-glazed windows, and exterior cladding (Yakisugi charred wood or Lunawood Thermowood). Every layer is selected for thermal performance, health safety, and environmental impact.
All primary materials are sourced from certified European suppliers, ensuring full traceability and compliance with EU environmental standards.
Where do Nexa Modular Solutions materials come from?
From certified partners across the European Union. Our supply chain spans multiple EU countries, from Germany and Austria for insulation and ventilation systems, to Finland for Lunawood Thermowood cladding, to Romania for structural timber and manufacturing.
Every supplier operates within EU standards and regulations.
What certifications do Nexa Modular Solutions materials carry?
Two key independent certifications at the building level: Passivhaus Component certification (energy and structural performance verified by the Passivhaus Institut in Darmstadt, Germany) and EPD, Environmental Product Declaration (full lifecycle environmental impact, independently audited).
Additionally, our wood materials carry FSC and PEFC chain-of-custody certification where applicable, proving the timber comes from sustainably managed forests.
Understand what Passivhaus certification requires.
THE SUSTAINABILITY
Is wood construction really better than concrete or steel?
It’s not even close. Timber is the only structural building material that absorbs CO2 as it grows. BIOBUILDS’ EPD proves our homes are carbon-negative: the carbon stored in the timber exceeds all emissions from manufacturing, transport, and construction combined.
Cement production alone accounts for 8% of global CO2 emissions. Steel requires extreme energy to produce. Wood is incredibly more sustainable, more efficient, healthier for occupants, and grows back. It’s better by every measure.

What are FSC and PEFC certification and why do they matter?
FSC (Forest Stewardship Council) and PEFC (Programme for the Endorsement of Forest Certification) are independent standards that guarantee timber comes from sustainably managed forests: forests that are replanted, biodiversity-protected, and regularly audited.
BIOBUILDS’ wood materials carry these certifications where applicable, ensuring your home did not contribute to deforestation. These are material-level certifications, meaning they apply to the individual wood products that go into each module.
