A distance no less than 2" will be maintained between any combustion appliance flue and combustible materials, unless zero clearance flue is in place
All ventilation systems will maintain a continuous connection and terminate to the outdoors
All broken mushroom vents will be replaced or removed and sealed
All plumbing stacks will be terminated to the outdoors
Non- IC rated light fixtures will be replaced with airtight IC -rated fixtures
All recessed lights will be labeled as having an air leakage rate not more than 2.0 CFM when tested in accordance with ASTM 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
4.1003.15b
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
4.1003.15c
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
4.1003.15d
Insulation will be installed to a density of 1.5 to 1.6 pounds per cubic foot
Using fill tube, 100% of each roof cavity will be filled to a consistent density
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 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
Avoid clogging of the cavity and the fill tube
Prevent damage to the ceiling
Fire safety will be maintained
4.1003.15e
Reinstall the gable end vents
Prevent pest intrusion into attic
Protect installed insulation
4.1003.15f
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
4.1003.15g
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
