Insulating Cathedral Ceiling - Northern Climate
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.
