Abstract
An intumescent catalyst mounting mat is provided by cutting a single piece of mat into a desired profile and cutting a slit about 1/2 way through the thickness of the mat at a selected fold line. The mat is then easily folded upon itself to create a double thickness mat that is already secured to the next layer and may have any desired profile.
