Attic comfort in Columbus: insulation, air sealing and ventilation
Insulation, air sealing and ventilation have different jobs. Insulation slows heat transfer, sealing limits air leakage through the ceiling, and a planned ventilation path connects outdoor intake and exhaust. Adding a fan alone does not answer every comfort problem.
What to ask before choosing the work
At the eaves, insulation must leave the designed intake pathway clear. Baffles help preserve that air space. Ask an assessor to check existing vent locations, insulation coverage, ceiling penetrations and bathroom exhaust routing before recommending equipment.
