Fiberglass batts have been around for many years and are far and wide the most popular insulation option for new construction and remodeling, being installed before the drywall goes up. They have multiple key benefits:

• When installed on the attic floor, they’re the easiest product to walk across for future maintenance.
• For new construction and commercial work, less time means a lower price point – a great option for investment properties and house flips.
• Available in multiple R-values and thicknesses.
• High Density batts available for vaulted ceilings, flat roof assemblies, and  upgrades to exterior walls.
