Methods and Verification of Density Dense pack has National Weatherization Conference a density of 2005 pounds per cubic foot or more (well, Is probably OK). Rick Karg 2005 Karg Associates Photo source: Jim Fitzgerald 2. Dense Pack Cellulose Insulation : Methods and Verification of Density Dense Pack Cellulose Insulation : Methods and Verification of Density High Density Cellulose .. What We Will Talk About Pros and cons of Dense pack Cellulose . Has the greatest advantage in houses with Insulation blowing machines.

2 Leaky walls, especially walls where one cavity is Wall drilling. connected to the next (plaster and lathe). High Installing Dense pack Cellulose . R-values and reduces leakiness significantly. The delivery system. Has less of an advantage in tighter dwellings Tubing tips. with drywall and sheet sheathing. High R-values, Power quality. but does not reduce leakiness very much. Safety. Verification of Insulation quality. 3 4. Dense Pack Cellulose Insulation : Methods and Verification of Density Dense Pack Cellulose Insulation : Methods and Verification of Density Methods of Installing Cellulose Cellulose Grades Cellulose Insulation from most manufacturers is Two-hole with nozzle.

3 Available in at least two grades that are Straight. characterized by the fire retardant. Directional or cup. The fire retardants are usually 1) a mix of One-hole with tubing. ammonium sulfate and boric acid or 2) boric acid only (termed borate only ). Summer grade. Although it is about 7 to 10% more expensive, Winter grade. borate only grade is recommended because it More? is less corrosive. 5 6. Rick Karg, 1. Dense Pack Cellulose Insulation December 2005.

4 Advantages and Conduct pre-weatherization blower door test.. Inspect interior surfaces for holes and strength. Disadvantages of Check for knob-and-tube wiring.. Check for voltage drop. Dense Pack Cellulose Check for ducts or pipes in exterior walls. Check for location of electrical fixtures. Respect all clearances. Watch for pocket doors. Check bathtub and plumbing 8. Dense Pack Cellulose Insulation : Methods and Verification of Density Dense Pack Cellulose Insulation : Methods and Verification of Density Advantages of Dense Pack - 1 Advantages of Dense Pack - 2. No settling at top of cavity. Better equipment and equipment Uniform R-value. maintenance required Insulation blowing Reduction of house CFM50.

5 Machine and delivery system. Usually less wall open-up and close-up Higher degree of professionalism required time. more knowledge, greater care. Pays back Greater safety for installation crew. in the long term. Quieter indoors. 9 10. Dense Pack Cellulose Insulation : Methods and Verification of Density Dense Pack Cellulose Insulation : Methods and Verification of Density Disadvantages of Dense Pack - 1 Thermal Conductivity vs. Density More Insulation is installed, so more time Vertical axis is inverse of required to blow (this might be outweighed R-value. For example, by wall open-up and close-up time). is equivalent to an R-value of Greater possibility of damaging interior wall material.

6 Reduction in R-value (from at lbs/ft3 to at lbs/ft3), but Source: ASHRAE Handbook of Fundamentals 2001, p insignificant. 11 12. Rick Karg, 2. Dense Pack Cellulose Insulation December 2005. Dense Pack Cellulose Insulation : Methods and Verification of Density Dense Pack Cellulose Insulation : Methods and Verification of Density Disadvantages of Dense Pack - 2 Green Advantages of Cellulose Requires higher quality equipment Is probably the greenest of insulations Insulation machine, generator, delivery available. About 80% post-consumer system. recycled newspaper by weight. Lowest of major insulations in embodied Requires higher degree of equipment energy both in Btu/lb.
