The Answer:
Both spray foam and batt insulation have their advantages, but spray foam generally offers superior performance. Spray foam creates an airtight seal, providing better energy efficiency, moisture resistance, and a longer lifespan. Batt insulation, while more affordable upfront, doesn’t offer the same level of sealing and may need replacing sooner.
Did you know?
Spray foam insulation can reduce air leakage by up to 50%, while batt insulation might only reduce it by about 20-30%, leading to higher energy savings over time.
