Noise reduction

[Shane T]

I have a 47 blower and have recently removed the small Cowl silencer from immediately below the blower. I installed 3" plumping to a larger compact Universal silencer mounted under the van. The sound under the van is very tolerable but inside the van and outside the doors it is loud. The van interior is paneling over foam insulation and plywood with a rubber mat on the floor. I believe the noise is reverberating from the blower case and plumbing. I want to place some noise reduction panels in the area of the blower & plumbing. Any ideas what I can use? It needs to be able to handle some heat.

This is the company from whom I used to buy sound deadening sheets for the inside panels of TM units to deaden engine, blower, and exhaust system noise emanations.
