Duct wrap removed before more attic insulation
Example project
- Home
- 1950s single-story house in Union City, with its ducts in the attic
- Original request
- Seal the ducts and add attic insulation after a home energy audit
- Testing
- Samples of the white duct wrap and the joint tape on the main runs
- Found
- Asbestos in the wrap and the tape; the loose insulation is clear
- Work
- About 50 linear ft of wrap and tape on the first runs out of the furnace, wet, in a sealed attic
- Timeline
- Lab results in a few days, then two days of removal before the insulation crew
- Estimated cost
- $3,100
In this example, the owners of a 1950s house in Union City get a home energy audit. The auditor finds round attic ducts wrapped in white insulation held with metal bands, and loose insulation over the floor. The owners want the ducts sealed and more insulation added.
