Johns Manville Attic Protector® Blown-in Fiberglass Insulation Installation

  • Specification 1

  • Specification 2

    • When adding insulation to your attic, you should first consider how much you already may have and what you need.

      1. How much insulation do I have?

      Slide a tape measure or yardstick into your attic insulation. You should have up to 19 inches or R-49*.

                 ______ Depth of existing insulation

  • Specification 3

    • *The US Dept of Energy recommends R-38 or R-49 (a total of 16-19 inches of fiber glass blow-in insulation - JM Attic Protector®) across most of the lower 48 states.

      Note: The “R” in R-value stands for “resistance” to heat flow. The higher the R-value, the greater the insulating power. Save more money on your energy bills by using higher R-values. Your local building code will give you the minimum R-value requirements. R-values may be added together. Add more insulation to get the R-value you need.

  • Specification 4

    • 2. How much should you add?

                16-19 Inches you need (R-38 to R-49)
                 - ______ Inches of existing
                 = _____   Inches to add

      3. How big is your attic?

                  ____  Length of area
               x ____ Width of area
               = _______ Square feet

  • Specification 6

  • Specification 7

    • Preparation and installation:

      1.  Visit Lowe’s to rent a blower machine.

      2.  Light the attic with portable safety lights and lay boards across the wooden joists to walk on.

      3.  Seal air leaks with caulk for small gaps and foam for gaps ¼-inch to 3 inches.

      4.  Install vent chutes by stapling directly to roof decking where the attic is vented to the outside.

      5.  Protect heat sources by building barriers to keep insulation at least 3 inches away from can lights and furnace flues.

      6.  Mark the desired depth of insu  lation in several locations so you’ll know when you’ve installed enough.

      7.  Build a dam around the attic access door using fiberglass insulation batts or wood.

      8.  Work as a team. One person in the attic, one below with the machine.

      9.  You can add insulation to a 100 sq ft attic in under 2 hours.

      10.  Blow the insulation to the desired depth, starting at the edges and working back towards the attic access door. (See complete instructions on the machine.)
