Benefits of Johns Manville Attic Protector Fiberglass Blown-In Insulation

How to Properly Install Johns Manville Attic Protector in Your Ceiling
1. Prepare the Attic
– Clear debris, insulation remnants, and storage items.
– Seal air leaks around vents, chimneys, and light fixtures with caulk or foam.
2. Rent or Hire Equipment
– A professional-grade insulation blower ensures consistent fiber distribution.
– Protective gear — respirator, gloves, goggles, and coveralls — is essential.
3. Load and Blow
– Follow the machine manufacturer’s guidelines to feed insulation fibers.
– Start at the farthest point from the attic entrance, working backward to avoid walking on freshly insulated areas.
4. Achieve Uniform Depth
– Aim for 12–14 inches of insulation to reach the desired R-value (verify local building codes for minimum requirements).
– Use depth markers on joists or stakes to maintain consistency.
5. Final Touches
– Lightly rake the surface to level any clumps.
– Check for coverage around recessed lights and wiring, but maintain required clearances from heat sources.
– Clean equipment and dispose of residual insulation according to local regulations.
Johns Manville Attic Protector vs. Other Ceiling Insulation Options
• Batt Insulation: Pre-cut batts can leave gaps in odd-shaped areas, reducing overall effectiveness. Johns Manville Attic Protector flows into voids for a complete seal.
• Cellulose Blown-In: While eco-friendly, cellulose has a lower R-value per inch (around 3.2) and can settle over time. Fiberglass maintains loft and performance longer.
• Mineral Wool: Offers good fire resistance but tends to be more expensive and heavier. Johns Manville Attic Protector combines affordability, lightness, and high R-value.
• Spray Foam: Provides excellent air sealing but comes at a premium cost and may off-gas chemicals. Fiberglass blown-in insulation is a healthier, budget-friendly alternative.
