Guide
Description
Guide describing approaches to burying and encapsulating ducts in unconditioned attics to increase the overall R-value of duct insulation.
Guide
Description
Vapor retarder plastic should not be installed over fibrous insulation on basement or crawlspace walls; rigid foam or spray foam should be installed directly against the concrete, behind the blanket insulation.
Guide
Description
Guide that illustrates how and when to encapsulate ductwork in unconditioned attics, increasing the R-value of duct insulation, mitigating condensation issues, and reducing air leakage.
