Heat Rises
In winter, your heated air rises into a cold attic. In summer, a 140°F attic radiates heat down through the ceiling all afternoon. Insulation slows both.
Air Leakage
Most attics leak conditioned air through top plates, recessed lights, and chases. Air sealing first, then insulating, captures the full savings.
HVAC Runtime
A properly insulated attic cuts HVAC runtime by 20-40% in most Chattanooga homes — directly reflected on your power bill.
