Introduction to Fiberglass Blown-In Attic Insulation

In Portsmouth, Virginia, your attic is the key to lower energy bills, consistent comfort, and long-term home protection. Universal Insulation Doctor specializes in fiberglass blown-in insulation with PestGuard Insulation™ — the only attic insulation that combines superior thermal performance with built-in pest deterrence.

Using high-density fiberglass blown-in insulation, we achieve R-49 — the Virginia-recommended standard for Climate Zone 4. Paired with PestGuard™ treatment, this system blocks heat loss, prevents pest nesting, and resists moisture in Portsmouth’s humid, coastal environment.

Why Fiberglass Blown-In + PestGuard™ in Portsmouth?

Portsmouth’s hot, humid summers (avg. 90°F+) and damp winters (avg. low 32°F) demand insulation that performs without fail. Old or insufficient attic insulation causes:

  • Up to 30% energy loss through the roof
  • Hot upstairs rooms and cold drafts
  • Pest infestations ( ants, roaches) in warm, undisturbed attics

Benefits of Fiberglass Blown-In with PestGuard™

  • Energy Savings: Reduce cooling by up to 25%, heating by 15%
  • Even Comfort: Eliminate hot/cold zones floor-to-floor
  • Pest Protection: PestGuard™ naturally repels insects — no harsh chemicals
  • Moisture Resistance: Breathable design prevents condensation
  • Fire Safety: Non-combustible, Class A fire-rated
  • Quiet Home: Reduces noise from I-264, shipyards, and naval bases

Attic Insulation Upgrade in Cavalier Manor Portsmouth – R-49 for Year-Round Comfort

A homeowner in the Cavalier Manor area of Portsmouth contacted Universal Insulation Doctor after struggling with hot upstairs rooms in the summer, cold drafts in the winter, and steadily increasing energy bills. During our free attic inspection, we found low insulation levels, uneven coverage, and areas where the existing insulation had settled and lost effectiveness.

Our team sealed air gaps around attic penetrations, installed proper ventilation baffles to improve airflow, and added blown-in fiberglass insulation to achieve the recommended R-49 level for Virginia homes. We ensured full, even coverage to eliminate heat loss and improve overall performance.

After the project, the homeowner reported more consistent temperatures throughout the home, improved comfort upstairs, and reduced HVAC run time. Their attic is now properly insulated, better protected from moisture issues, and performing efficiently—installed by a trusted local company serving Portsmouth and all of Hampton Roads.
