Introduction to Fiberglass Blown-In Attic Insulation

In Williamsburg, Virginia, your attic is the silent guardian of comfort, energy savings, and historic home preservation. Universal Insulation Doctor installs fiberglass blown-in insulation with PestGuard Insulation™ — the only attic solution that delivers R-49 performance and built-in pest protection tailored for Williamsburg’s unique climate and architecture.

Using high-density, formaldehyde-free fiberglass blown-in insulation, we achieve R-49 — the Virginia standard for Climate Zone 4. PestGuard™ is seamlessly integrated during installation to naturally repel ants, roaches and othe insects — ideal for Williamsburg’s humid summers, mild winters, and historic crawl-through attics.

Why Fiberglass Blown-In + PestGuard™ in Williamsburg?

Williamsburg experiences hot, humid summers (avg. 92°F+) and cool, damp winters (avg. low 30°F). Inadequate attic insulation results in:

Up to 30% energy loss through the roof
Overheated second floors and drafty first floors
Pest nesting in warm, undisturbed attics — especially in older homes

Benefits of Fiberglass Blown-In with PestGuard™:

Energy Savings: Reduce cooling by up to 25%, heating by 15%
Balanced Comfort: Eliminate temperature swings in multi-story homes
Pest Defense: PestGuard™ safely blocks insect nesting — no harsh chemicals, no odors
Moisture Control: Breathable design prevents mold in humid conditions
Fire Safety: Non-combustible, Class A fire-rated
Quiet Living: Reduces noise from I-64, Colonial Parkway, and nearby trains
