3294 is a 5 mil rayon which is a non-woven, synthetic backing with a strip-coated low tack pressure sensitive adhesive for use in various venting applications to allow the confinement and outgassing of foam insulation. The non-woven backing conforms for effective sealing. It allows high air/gas permeability to promote minimal foaming voids. It has good burst strength and the uncoated areas have higher permeability.
