Envelope and Air Quality
Start with continuous insulation, careful air sealing, and vapor-smart membranes that manage moisture responsibly. Balanced ventilation with heat recovery supplies filtered fresh air while maintaining temperature stability. In a townhouse, we tucked ducts into a service spine, leaving ceilings intact for future access. VOC-free finishes and formaldehyde-safe substrates protected sensitive occupants. The air felt lighter, the dust settled less, and plants thrived. Maintenance became filter swaps rather than disruptive overhauls, keeping the calm intact.
