Sound deadening

[Bill Garamella]

Hello John,

I am in the process of replacing the flooring after having removed the doghouse
for valve
lashing, re-insulation. On the doghouse I used 2", 2# sq./ft. quilted fiberglass
and lead
sandwich with mylar face. This stuff is very good but very heavy too. I was able
to obtain
it locally from Soundown so shipping charges were eliminated. I used Permatex
High
Temp RTV Silicone Gasket Maker to reinstall the doghouse. I purchased it at a
heavy truck
shop parts dept. About $15 a tube. I used about 1/2 tube

What am I using for a sub floor in the driver's area?

I am using the same sub floor throughout the front of the coach. From the the
driver's
side of the accelerator and brake pedals back to the salon side of the mid-door
entry way
where it meets ceramic floor (its all level). All the furniture and seat mounts
and seat belts
have been removed. I did not remove the built in couch. The vertical carpeting
is in good
shape so that is not being touched. This will save a lot of work and money.

The sub floor material is from Soundown it is 1/2" thick 2#/sq. ft. It One side
is dense
foam and the other is dense mass loaded vinyl. This should be installed vinyl
side up. The
Soundown rep stated some people make the mistake of putting vinyl side down and
this
defeats the sound deadening/vibration damping properties. The following link
will take
you to that particular product line. http://www.soundown.com/carpet%20under.htm

The finish floor is Dupont Laminate Henna Hickory, http://tinyurl.com/4gf39p . I
have
installed this material in the past and like it a lot. The finish floor needs
1/4" clearance
around the perimeter. Both floors will rest in place without fasteners or glue
and butt
nicely into the vertical carpet. If I ever need to get under the floor or, God
forbid, remove
the doghouse again, it will be relatively easy.
