FAQs About Blow-In Insulation
What is blow‑in insulation?
Blow‑in (or loose‑fill) insulation is composed of small particles—typically fiberglass or cellulose—that are pneumatically “blown” into attic spaces. It conforms tightly around obstacles, creating an effective thermal barrier.
Do I need to remove my old insulation first?
Not always. If existing insulation is in good condition and free of moisture or mold, we can install blow‑in insulation over top. If it’s degraded or contaminated, removal is recommended for best performance.
How long does installation take?
Most attic insulation jobs for an average‑sized Lethbridge bungalow take 4–6 hours. Larger homes or wall‑injection projects may take a day or more. We’ll give you a clear timeline at your estimate.
What R‑value should I aim for?
Alberta Building Code recommends R‑50–R‑60 for attics. We’ll calculate your ideal R‑value based on your home’s age and existing insulation.
