Climate Pro® Loose-Fill Fiber Glass Insulation

Johns Manville Climate Pro® loose-fill fiber glass insulation is made for installation in open attics to fill hard-to-reach areas like corners, edges and around framing. Climate Pro® insulation is a premium alternative to cellulose and does not settle or decay. For installing Climate Pro® in enclosed cavities, use the Blow-In-Blanket System® with a fabric covering to contain JM's blown-in insulation. It provides a custom fit for thermal and acoustical insulation in walls, ceilings and floors.

Redesigned for Efficiency and Speed
Johns Manville has redesigned Climate Pro® in 2012 to provide more coverage and save time during installation. Still part of the same compact package, Climate Pro® now features:

Installation Tips

  1. Remove any objects from the attic that might interfere with the proper application of the insulation.
  2. Make sure that any eave or soffit vents are not blocked.
  3. Place one or more attic rulers in each quadrant of the attic space. This will help you know when you have achieved the correct depth of insulation.
  4. Load the blowing machine hopper with insulation. The hopper should be kept nearly full so the insulation flow is smooth and even.
  5. Hold the hose parallel to the floor with the insulation falling 10' - 12' away. Begin at the far wall and work toward the center. Always blow in the direction of the joists. Be careful to step only on floor joists, or else you might accidentally put your foot through the finished ceiling below.
  6. Fill three or four joist cavities by moving the hose to the right and left. Where possible back away from the work to avoid packing the insulation. Be sure to get insulation to the top of the walls and low places. Don't cover eave vents.
  7. Avoid using your hand as a baffle to direct the insulation as it exits the hose. Do this only when necessary to avoid packing.
  8. Keep the hose close to the floor where insulation must go under obstructions like cross bracing and wiring. Insulation must be blown on both sides of these kinds of obstructions. If an obstruction has caused a low spot to occur, fill in the area.
  9. Check the thickness of the insulation, and check that you have used the correct number of bags per 1,000 sq. ft.
  10. Cavities, drops and scuttles should be covered with batts.

When and How to Hire a Contractor

Insulation contractors are trained in the installation of many different types of insulation. Plus, many offer additional installation services, such as fireplaces, doors and windows, and closets. Insulation contractors may work directly with your builder or can be hired directly by homeowners for new construction jobs or retrofit. It is always good to meet with and receive bids from a few contractors, making sure to thoroughly explain your needs. Most contractors will offer upgrade packages and can often explain the energy savings benefits of such upgrades.
