Engine room noise/insulation material

[Richard Hayden]

While my radiator is out I am renewing the heating hoses and installing new
insulation in the engine room. Everything was going along fine till I
discovered that I am a little short of enough insulation material to finish the
job. Has anyone who has done this job have any leftovers? What I am using is
1" thick with foil on one side. There is also a pvc layer between two layers of
open cell foam. I need a piece 46" x 51" or pieces that add up to that. (The
actual pieces needed are 22" x 48" plus 24" x 51").

Any help will by greatly appreciated.

Oh yes, I'll by glad to pay for the material as well as the shipping.

Thanx

Dick, I am new to BB's, having one just a couple of months, but I had
my Cat house off improving intake airflow and adjusting valves. My
insulation was shot so I started looking around for some affordable
insulation material and happened on a website about quieting engine
noise and reducing cab heat in Hummers. (diesel engine right between
driver and passenger) The author wrote that he had found (and used) a
material used to line duct work called Duct Liner. I had already
applied a layer of Astro-Foil (kind of a bubble wrap with aluminum on
both sides) that I had laying around the shop. I went to one of our
local HVAC contractors here and bought WAY more than enough material
to insulate the Cat house. Cost $15. I cut a small sample, put it on
vise (as I did with the Astro-Foil) tried to ignite it on both sides,
then proceded to insulate the Cat house. My 1100 mile road test was
leaving Yuma a couple of weeks ago (100 deg) with 6500# auto hauler
(with 4Runner) in tow. 7300' climb up to Flagstaff, then to Moab via
Mexican Hat and up and over Mokee Dugway to Blanding. We NEVER
experienced any heat radiating through the Cat house. Not once. Maybe
you experienced guys already know about this stuff, if so I couldn't
find it on the forums. On my road test after a couple of particularly
hard climbs, I lifted the Cat hood (with fire extinguisher at hand)
and was surprised to find the interior insulation material no warmer
than my hand. The Cat house was simply not absorbing and retaining
heat. Anyway, not very scientific but worked for me. Total cost,
about $25. Brad Bloxham 35' 78 3208NA Yuma AZ, now Idaho Falls, ID---

Brad,

Interesting report. Since I like first hand reports, I went to
Google on Duct Liner and found that is a generic name with several
different companies making a product with that name (Owens Corning,
CertainTeed, Knauf, Crown Acoustic, etc.).

Which manufacturer made the product you used?

Thanks Brad for the comeback. I think I have found what I need from Stephen
Birtles. It sounds to be similar to what I have been using.

Bye the way, what were you doing in Yuma this late? We winter in that area.

Happy travels.

Ok, Mike. The product was Owens Corning "Quieter". It took me a while
to find the brand name. I am in Idaho and the left over materials is
in Yuma. I called the supplier. They have 2 thicknesses and I used
the heavier of the 2. 1 or 1 1/2 inch as I recall. Brad Bloxham 78
