Introduction
Upgrading your home’s insulation is one of the most effective ways to boost comfort, lower energy bills, and increase property value. Johns Manville Attic Pro Blown Floor Insulation brings together advanced fiberglass technology and simple installation to transform under-insulated floors and attics into high-performance thermal barriers. In this article, we’ll explore why this product stands out, how to install it correctly, and how it compares to other insulation types.
H2: Benefits of Johns Manville Attic Pro Blown Floor Insulation
• Exceptional Thermal Performance
Johns Manville Attic Pro Blown Floor Insulation delivers an R-value of 3.7 per inch, trapping heat in winter and reflecting it in summer. Properly installed at a depth of 16 inches, it achieves an overall R-38 to R-60 rating, depending on local building codes and climate zones.
• Complete Coverage and Air Sealing
Unlike pre-cut batts that can leave gaps, blown-in fiberglass fills every nook and cranny. The loose-fill fibers conform around pipes, wiring, and joists—eliminating voids that cause drafts and heat loss.
• Superior Sound Attenuation
The dense, interlocking glass fibers absorb airborne noise, reducing sound transfer between floors. Whether you have a home office, playroom, or rental space below, this insulation muffles footsteps, voices, and appliance hum.
• Fire Safety and Durability
Johns Manville Attic Pro is non-combustible, made from inorganic materials that resist fire without adding toxic fumes. It won’t settle or degrade over time, maintaining consistent performance for decades.
• Eco-Friendly Composition
Each bag contains up to 80% recycled glass, making Attic Pro an environmentally responsible choice. Plus, it’s formaldehyde-free, helping you maintain healthier indoor air.
H2: How to Install Johns Manville Attic Pro Blown Floor Insulation
1. Prepare Your Space
a. Clear the attic or subfloor area of debris and obstructions.
b. Seal large gaps around ductwork and plumbing with expanding foam or caulk to prevent air leakage.
c. Wear protective gear—gloves, goggles, and a dust mask—to avoid irritation.
2. Calculate Material Needs
a. Measure the square footage of the floor or attic.
b. Use Johns Manville’s online calculator or follow packaging guidelines to determine total bags required for your target R-value.
3. Rent or Purchase a Blower Machine
a. Most home centers rent fiberglass blowing machines by the day.
b. Ensure the hopper and hoses are clean and in good condition.
4. Load and Distribute Insulation
a. Feed the fiberglass into the machine hopper.
b. Starting at the farthest corner, move the hose in a systematic pattern, maintaining a consistent depth.
c. Use a depth marker—a couple of wooden stakes tied with string—to ensure uniform coverage.
5. Check and Finish
a. Once you’ve reached the recommended depth, turn off the blower and inspect for any thin spots.
b. Add more insulation where needed.
c. Replace attic hatches or subfloor panels, and clean up residual loose fibers.
H2: Comparing Johns Manville Attic Pro Blown Floor Insulation to Other Options
• Batt Insulation vs. Fiberglass Blown-In
– Batt insulation can be faster for small jobs, but gaps around joists and wiring compromise its effectiveness. Blown-in fiberglass conforms tightly, ensuring superior air sealing.
• Cellulose vs. Fiberglass Blown-In
– Cellulose offers good thermal performance but tends to settle over time and can absorb moisture. Johns Manville fiberglass remains light, dry, and resilient for decades.
• Spray Foam vs. Blown-In Fiberglass
– Spray foam provides excellent air sealing but comes at a higher cost and may require professional installation. Blown-in fiberglass delivers strong R-values at a lower price point and can be DIY-friendly.
H2: FAQs about Johns Manville Attic Pro Blown Floor Insulation
Q: Can I install this insulation myself?
A: Yes. With proper protective gear and a rented blower machine, most homeowners can tackle the job in a day. Always follow local building codes.
Q: Will it settle over time?
A: Johns Manville Attic Pro Fiberglass Blown Floor Insulation is designed to resist settling. You may inspect after a few years and top off thin areas if necessary.
Q: Is it compatible with radiant barrier or foil-faced insulation?
A: Absolutely. Use reflective barriers on the underside of the roof deck for added summer heat rejection, then install Attic Pro against the subfloor to trap conditioned air.
Q: How long does insulation last?
A: When properly installed, fiberglass blown-in insulation can last the lifetime of your home—often over 30 years—without significant degradation.
