In very airtight buildings even low material emissions matter. How VOC and SVOC emissions from finishes, adhesives, and sealants affect indoor air, and how natural wood systems such as MAFI's can reduce them at the source.

Key points

• How interior materials affect indoor environmental quality in airtight buildings.
• Natural, low-emission materials as source control for indoor air quality.
• Solid and engineered wood compared: binders, emissions, and performance.
• How VOC and SVOC emissions from materials affect indoor air.
