3M 7010312339 Vent Tape 3294 Pink 1.5in X 36yd 4.0 Mil

Product Description

The 3M 7010312339 is a pink, air-permeable vent tape designed for applications requiring high outgassing rates during foam insulation processes. The non-woven backing carries a strip-coated acrylic adhesive, meaning uncoated zones retain higher permeability to help minimize foaming voids as expanding foam cures. The tape measures 1.5 inches wide on a 36-yard roll and carries a nominal thickness of 4.0 mil. It is a purpose-built solution for contractors and installers managing confinement and controlled outgassing in foam insulation work.

This tape is used in venting applications where trapped gases must escape during foam expansion without displacing the foam itself. Typical scenarios include cavity insulation work in residential and light commercial construction, where the tape is applied to confine foam insulation while allowing gas to vent through the permeable backing. Installers working with spray foam or foam-in-place insulation systems will find this tape suited to controlling outgassing at panel seams, joints, and containment boundaries.

Key Features

• Air-permeable non-woven backing allows controlled outgassing during foam insulation cure
• Strip-coated acrylic adhesive leaves uncoated areas for increased permeability, helping reduce foaming voids
• 4.0 mil nominal thickness for handling durability during application
• 1.5-inch width on a 36-yard roll for efficient coverage in continuous runs
• Pink color aids visual identification on the job site

Compatibility

Designed for use in venting applications requiring high outgassing rates, including confinement and outgassing of foam insulation systems.

Installation Notes

This tape is typically applied by insulation contractors or construction trades handling foam insulation work. Surfaces should be clean, dry, and free of dust or loose material before application to ensure proper adhesion. Apply with consistent hand pressure along the full length of the tape to seat the adhesive. Follow all foam insulation manufacturer guidelines and applicable building codes regarding ventilation and vapor management when incorporating this tape into an assembly.
