Insulating Crawlspace Bottom of Floor Joist

Crawlspace Insulation - Bottom of Floor Joist

Installation Instructions

  • Inspect the crawl space and make any needed repairs before installing InfraStop® double bubble insulation.

  • Check the crawl space to determine whether the floor joists are 16” or 24” on-center.

  • Determine if there are water pipes and heating ducts which hang below the floor joists. They will need to be insulated. InfraStop® Pipe Wrap and Duct Insulations are designed specifically for this use. There is no need to wrap water pipes or duct work that fall between floor joists. InfraStop® will provide adequate insulating without extra wrapping.

  • Start at the end of the house and face staple to the bottom of the floor joists. Seal seams with InfraStop® Foil Tape to create a vapor barrier. At the end, staple up to the sub-floor or band board.

  • Note: Existing mass insulation in the joist cavities must be dry prior to installing the InfraStop® product.
