E 283 at a 75 pascals pressure differential
All obvious ceiling penetrations will be sealed
The space between combustion appliance flues and the ceiling will be sealed with fire-rated materials
All roof, attic, and ceiling assemblies will be structurally sound:
Loose ceiling panels will be secured Temporary ceiling bracing will be recommended during the insulation installation process Dishing and pooling issues that allow standing water will be addressed
All known roof water leaks will be repaired before installing installation
Ensure occupant and worker safety
Verify attic space is ready to insulate
Ensure structural integrity of the roof and ceiling assembly
Prevent intrusion of bulk moisture
Prevent damage while installing insulation
4.1003.9b
Access to the attic cavity will be created through the gable vents.
Attic will be visually inspected for the location of existing insulation, wiring, flues, obstructions, hazards, and construction type
Create access to the full attic cavity
Maintain the integrity of the roof truss
Determine technique for installing insulation
4.1003.9c
Blowing machine pressure test will be performed with air on full, feed off, and gate closed
Hose outlet pressure will be set in accordance with manufacturer specifications
Ensure machine is capable of delivering uniform insulation density and coverage
4.1003.9d
Insulation will be installed to a density of 1.5 to 1.6 pounds per cubic foot
Using fill tube, 100% of each cavity will be filled to a consistent density
Fill tube will be inserted within 6" of the end of each attic cavity
Insulation will be installed into the void of the attic cavity:
If existing insulation is roof-mounted, insulation will be blown below If existing insulation is ceiling-mounted, insulation will be blown above If existing insulation is mounted at both locations, insulation will be blown in between Insulation will be filled no higher than the top of the truss
Flame spread and smoke-developed index for insulation will be a flame spread rating of 25 or less and a smoke development rating of 450 or less when tested in accordance with
ASTM

E84
Fill entire attic cavity to the prescribed R-value to reduce air
infiltration
Infiltration
The uncontrolled passage of outside air into a building through unintended leaks in the building envelope
Avoid clogging of the cavity and the fill tube
Prevent damage to the ceiling
Allow roof to be returned to original position
Fire safety will be maintained
4.1003.9e
If the roof is sliced:
A solid metal ridge cap will be centered over the slice A flexible and durable sealant will be sandwiched between the roof and the ridge cap Screws will be installed to prevent wrinkles and create a permanent seal Screws will not go into any wood framing A durable and flexible final coating will be applied over the screws and edge of the ridge cap to create a continuous seal between the roof and the perimeter of the ridge cap For holes that are drilled or cut, the initial patch will be applied using the following procedure:
At least 6" of surface surrounding the opening will be cleaned before patch is installed Sealant will be continuous and applied in between the patch and the roof Sealant will be an all-weather adhesive that is flexible and durable If a metal patch is used:
Patch will overlap the opening by 2" on all sides Gauge will be equal to or greater than the roof material Fasteners will be installed to prevent wrinkles and create a permanent seal If a plug is used, it will be flanged and have a tight fit Screws will not go into any wood framing A durable and flexible 45 mil adhesive patch will be applied in accordance to manufacturer specifications over the initial patch and will have at a minimum:
Tear strength of 640g Elongation of 380% Application temperature no lower than 55°F and no greater than 110°F Services temperature no less than -25°F and no greater than 150°F Adhesive patch will overlap the initial patch by 2" on all sides A durable and flexible final coating will be applied over the adhesive patch to create a continuous seal between the roof and the perimeter of the patch All remaining seams, edges, and penetrations will be sealed as necessary Effectively patch and seal all openings
Create a durable patch that will prevent roof leaks
4.1003.9f
Installation process will be considered complete when installer has verified that damage has not occurred to the roof or ceiling assemblies during the installation process
Verify the integrity of the house has been maintained
4.1003.9g
A dated receipt signed by the installer will be provided that includes:
Insulation type Coverage area R-value Installed thickness and minimum settled thickness Number of bags installed in accordance with manufacturer specifications Document job completion to contract specifications
Confirm amount of insulation installed
Ensure ability to match bags required for total area complete
Comply with 16 CFR 460.17
