Best Insulation Types for Maryland Homes
Blown-In Cellulose
Blown-in cellulose is one of the best insulation choices for Maryland homes, offering excellent coverage in attics and hard-to-reach spaces at $1.05-$2.50/sq ft per square foot installed. Made from recycled paper fiber treated for fire and pest resistance, cellulose fills gaps and settles evenly to block drafts specific to Maryland's climate. It's a top pick for homeowners adding insulation over existing material without major demolition.
Spray Foam
Spray foam delivers superior air sealing and insulation performance for Maryland homes at $1.90-$4.30/sq ft per square foot installed. Both open-cell and closed-cell spray foam expand to fill every crack and gap, making it ideal for Maryland's climate demands — whether extreme heat, cold, or humidity. The higher upfront cost pays off through 15–20% lower energy bills and a lifespan exceeding 80 years.
Fiberglass Batt
Fiberglass batt is the most budget-friendly insulation option for Maryland homeowners at $0.65-$1.80/sq ft per square foot installed. Pre-cut rolls fit standard wall cavities and attic joists, making it straightforward to install in new construction and open-framing renovation projects across Maryland. While not as airtight as spray foam, modern fiberglass batts with faced vapor barriers perform well in Maryland's conditions when properly installed.
