| 4.1402.3a
Drainage | A continuous drainage plane at the interior surface of the exterior basement wall will be created from the top of the wall to a drainage field at the bottom of the wall or sub-slab Drainage field will be run to daylight or pumped to the outside | Remove moisture on the surface of the exterior basement wall |
| 4.1402.3b
Rough finish walls (e.g., rubble walls) | Drainage plane will be replaced with a waterproof membrane Only a nonabsorbent insulation that complies with
ASTM
ASTM
ASTM International, www.astm.org
C665-06 will be applied Insulation will adhere to the waterproof membrane without voids Drainage field will be run to daylight or pumped to the outside | Create an air and moisture barrier on the interior side of the exterior basement wall and allow the insulation to conform to the irregularity of the surface Improve thermal performance of the basement and the living space |
| 4.1402.3c
Thermal barrier, insulation | A nonabsorbent insulation will be used with a minimum expected service life of 10 years A fire-rated material will be used if the insulation is left exposed | Improve thermal performance of the basement and the living space |
| 4.1402.3d
Location | Insulation will be installed continuously from the top of the band joist to the top of the slab | Maintain a continuous
thermal boundary
Thermal boundary
The separation between the interior and exterior environments of a building that slows heat flow
on the interior side of the exterior basement wall |
| 4.1402.3e
Termite protection | Where termite pressure exists, if subslab drainage is installed, termite treatment will be performed before reinstalling the slab | Provide termite protection |
| 4.1402.3f
Insulation attachment | Insulation will be attached with a durable connection equal to or better than the manufacturer specifications, whichever is more durable A minimum expected service life of 10 years will be ensured | Secure
thermal boundary
Thermal boundary
The separation between the interior and exterior environments of a building that slows heat flow
without compromising the insulation |
| 4.1402.3g
R-value | Regional
IECC
IECC
International Energy Conservation Code
will be followed for required R-value | Improve thermal performance of the basement and living space |
| 4.1402.3h
Sealing | A continuous
air barrier
Air barrier
The separation between the interior and exterior environments of a building that slows air flow to the point that no smoke movement is visible at 50 pascals of pressure difference across the boundary
on the warm side of the
thermal boundary
Thermal boundary
The separation between the interior and exterior environments of a building that slows heat flow
will be installed, including floor-to-wall and wall-to-ceiling connections | Prevent convective air leakage from the basement, through the drainage plane, and back into the basement |
| 4.1402.3i
Finish wall requirements | International Residential Code (2012
IRC
IRC
International Residential Code
) will be followed for finished wall details in basements | Install a durable, finished wall |
| 4.1402.3j
Onsite documentation | A dated receipt signed by the installer will be provided that includes:
- Coverage area
- Thickness
- R-value
| Document job completion to contract specifications
Confirm amount of insulation installed
Comply with 16 CFR 460.17 |
