Insulating Cathedral Ceiling - Northern Climate

Installation Instructions

Attached to the Lower Edge of the Rafter - Below the Mass Insulation (Fiberglass) NORTHERN ZONE OF USA ONLY

  • Benefit - R-7.0 Summer & R-1.0 Winter and a Vapor/Moisture Barrier

  • Either the 16” or 24” wide product (depending on rafter spacing) is recommended.

  • The Staple Tab product is the easiest to work with for this application (but the Standard Edge product is equally effective).

  • Install venting (required in Cathedral Ceilings) and mass insulation per local codes and manufacturer’s installation instructions.

  • A minimum of a 0.75” air space is required on the underside (towards the interior of the home) of the InfraStop® product. This air space can be created in one of two installation methods:

  • 1. Tuck the product up into the cavity and staple to the side of the rafter every 2 to 3 inches fully enclosing the rafter cavity.

  • 2. Staple the product directly to the underside of the rafter every 2 to 3 inches fully enclosing the rafter cavity. Nail 1” x 2” (nominal) furring strips to the underside of the rafter (creating a continuous 0.75” cavity).

  • Install interior panel per local codes and manufacturer’s installation instructions.
