Low-emission materials: CARB Phase 2 / TSCA Title VI composite wood, FloorScore flooring, low-VOC paints
Indoor airPLUS §Low-Emission Materials — composite wood + flooring + paintsDescription
Indoor airPLUS specifies low-emission interior materials: composite wood products (plywood, particleboard, MDF) must comply with CARB Phase 2 / TSCA Title VI formaldehyde limits; interior paints and primers must meet South Coast AQMD Rule 1113 / GreenSeal GS-11 VOC limits; flooring must be FloorScore certified or have CDPH 01350 testing; adhesives + sealants must meet SCAQMD Rule 1168; carpet must be CRI Green Label Plus.
Why this exists
VOCs + formaldehyde from interior materials are the leading IAQ pollutants in new homes — peaking in the first 6 months. The CARB/TSCA Title VI composite wood standard has been federal law since 2018 (so it's already mandatory) but airPLUS catalogs the additional product certifications architects should specify on the materials schedule.
