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
