Batt Insulation in Kensington, MD

Batt insulation has two clear roles in Kensington homes. First, mineral wool acoustic batts in interior partitions where bedrooms back onto noisy rooms or face Connecticut Avenue or the MARC line — the right material for measurable sound reduction. Second, fiberglass batts in standard framed assemblies for additions, basement finishes, garage conversions, and remodel framing. We install both at code, with the careful detailing that determines whether a batt assembly actually performs.

Mineral Wool Acoustic Batts for Bedrooms and Home Offices

Kensington homes near Connecticut Avenue, Knowles Avenue, or the MARC Brunswick Line benefit from acoustic mineral wool batts in any wall, ceiling, or floor assembly between sleeping spaces and noise sources. We install in conjunction with resilient channel, double drywall, or acoustic sealants depending on the target STC rating. For historic homes where interior plaster is being preserved, we work from the exterior wall side or coordinate with remodel scopes to add acoustic improvements without affecting interior finishes.

Fiberglass Batts for Additions and Basement Finishes

For the additions, kitchen expansions, basement finishes, and garage conversions happening across Kensington, fiberglass batts remain the cost-effective standard. We use unfaced batts behind a separate vapor retarder where required, kraft-faced batts where cavity humidity allows, and we cut and fit around every electrical box, plumbing penetration, and obstruction so the batt actually fills the cavity. Sloppy batt installation is the single most common reason walls underperform — our crews are trained to do it right.

Mineral Wool for Fire-Rated Garage and Mechanical Walls

For garage-to-house separation walls, mechanical room walls, and any other code-required fire-rated assembly in Kensington homes, mineral wool batts are non-combustible and code-compliant. We install at the correct density and thickness for the rated assembly, coordinate with the GC on penetration sealing, and provide documentation for Montgomery County DPS inspections.
