Interior insulation requirements vary by locale; you should be familiar with your area’s standards. Recent codes for all but the southern and southwest tier states require conditioned spaces to have insulated walls: R-10 for continuous (spray foam) and R-13 for between the studs. Northern tier states require higher values. Unconditioned basements may be insulated on the wall, or on the ceiling between the basement and conditioned spaces above. Foam must be covered for fire safety unless rated for exposure.
Inspect for loose, falling. damaged, and missing or inadequate insulation. Always report indications of moisture issues: don’t forget your Infrared scan! Remember to use a Limitation Statement when appropriate due to finished surfaces or access restrictions.
Insulation is missing. This affects energy efficiency. Install insulation in accordance with local guidelines.
The level of interior insulation is considered inadequate by today’s standards. Install additional insulation in accordance with local guidelines.
There is loose or falling insulation. This affects energy efficiency. Install insulation in accordance with local guidelines.
Insulation is damaged to an extent to which its effectiveness is compromised. This affects energy efficiency. Replace the insulation.
There is exposed flammable insulation present. The insulation is required to be protected using fire-rated materials. Replace the insulation or cover it with approved materials.
The insulation is installed with the vapor retarder exposed; the Kraft paper barrier is flammable and should be covered. Replace the insulation, or cover the exposed vapor barrier with approved materials.
There are water stains on the insulation. The insulation is dry at the time of the inspection. Identify sources of moisture and mitigate any water penetration.
There are water stains on the insulation. The insulation is wet at the time of the inspection. The cause of the water must be identified. Identify sources of moisture and mitigate any water penetration. Replace the insulation as needed.
