Blown-In Cellulose Insulation for Kensington Homes

Kensington's Victorian cottages, bungalows, and early-20th-century colonials in Kensington Historic District, Ken-Gar, and Garrett Park Estates are well-matched to blown-in cellulose. The fiber settles into irregular bays, wraps around wiring and plumbing, and forms a tight mat that slows hidden air movement. The material uses 75 to 85 percent post-consumer recycled content and is treated with borate for fire resistance and long-term pest deterrence. Packed to the correct density, a cellulose cap resists settling for decades. With a full R-49 blanket in the attic, bedrooms track the thermostat more steadily through humid summers along Connecticut Avenue, University Boulevard, and Kensington Parkway and cool mornings in Montgomery County, and everyday noise from exterior rooms softens noticeably.

Attic Caps and Dense-Pack Walls in Kensington

Kensington's early-20th-century bungalows and colonials in the Historic District and Stoneybrook typically have attic floors insulated with original rock wool or loose fiber from the 1930s to 1950s that has settled significantly. A blown-in cellulose overlay restores R-49 coverage in one visit and works easily around the complex framing and diagonal sheathing present in these homes. We air seal top plates and open chases before blowing, set soffit baffles so ventilation moves in the right channel, blow a level cellulose blanket to the specified depth, and set depth markers so coverage can be independently verified. If existing insulation is already in the attic floor, a cellulose overlay suppresses internal air looping and lifts total R-value without a tear-out. Finished walls in Stoneybrook and Capitol View Park are dense-packed through small access points, packed to a defined pounds-per-cubic-foot target so the fill stays put around outlets, pipes, and framing and does not settle over time.

How DMV Foam Installs Cellulose Insulation in Kensington

DMV Foam's cellulose installation process in Kensington starts with a blower-door-assisted air-seal pass. Blown-in cellulose is a dense, forgiving material, but it cannot compensate for open top-plate penetrations, attic hatch perimeters that have never been sealed, or can-light housings that communicate directly with the attic. In Kensington's Victorian cottages, bungalows, and early-20th-century colonials, those penetrations are the rule, not the exception. We seal every identified bypass with two-part foam or caulk before the first bag of cellulose is loaded. For attic caps, we set depth markers at R-49 spacing across the floor and blow from the eave to the center, maintaining a consistent depth and density throughout. For dense-pack walls, we drill a single two-inch access hole per cavity, insert a fill tube, and blow until the cavity reaches 3.5 pounds per cubic foot — the density at which cellulose resists settling for decades. We plug and patch every drill hole and hand-finish flush to the drywall. All cellulose we install is GreenGuard Gold certified and contains no asbestos, formaldehyde, or crystalline silica. Post-install, we photograph treated areas, record R-values, and provide written documentation that satisfies Montgomery County DPS inspection requirements and supports the IRS Section 25C tax credit at filing time.
