I use the same technique as Dana just mentioned and it does work very
well. The blue rigid<br>
insulation we call Dow board has a very high compression strength. It's
used under concrete pads<br>
and between house foundation walls and the backfill with great success.
Good enough for batteries.<br>
<br>
What I haven't seen mentioned here is the material I've touted several
times on this list since '99<br>
called Structoglas. This is a very heavy duty fiberglass sheeting that
is used in kitchens, restrooms,<br>
dairy milk parlors, etc. We've been using it since '98 to line the
interior of our plywood battery enclosures. <br>
<br>
We make the bottom liner out of a single piece, no seams. We install an
8" high vertical "base trim" strip<br>
on all 4 sides and seal it with a high quality, 50 year silicon caulk.
12 years now, with several<br>
acid "incidents" caused by a few of our less maintenance conscious
customers, have proven to<br>
us that the fiberglass and the caulking hold up perfectly. I'm off grid
here and have been able to<br>
observe my Structoglas liner for 14 years. No degradation whatsoever.
Don't tell anybody but I've<br>
done some acid testing here myself ;-)<br>
<br>
The nice thing is that this is available at most Lowes and Home Despot
stores. A 4 x 8 sheet<br>
is usually around $34.00. One sheet will easily do an enclosure that
holds 12- L16s. It cuts easily<br>
on the table saw and can be scored and snapped as well.<br>
