Whether a specific building durability compromise or a full building renovation, Cozy Home Performance can address all Residential and Commercial building envelope/thermal boundary retrofications.
We look beyond the insulation and evaluate the entire building envelope/thermal boundary controls: air-moisture-insulation barriers. Our whole-systems approach and trained technicians will solve the root causes of envelope failures and meticulously design/install new assemblies for long term exceptional performance. Energy efficiency and occupant comfort begins with the integrity of the building envelope.
