Great Foam Insulation

[bobbert]

I noticed that another vandweller used a <u>minimal </u>amount of Luan in their Ford cargo van (covering their walls). In places where no luan was used, the bare wall of the van was visible &amp; in the nooks &amp; crannies, they had sprayed Great Stuff Foam Spray Insulation.<br><b><font size="4">Seriously speaking, is this as good as the sheets of foam board insulation that lines the walls in a cargo van?</font></b> <b><font size="4">Can this be a worthy substitute insulation (as opposed to R-13 &amp; etc.)?</font></b><br>In the attempt of future car dwelling, I was thinking of possibly insulating my car's interior with spray foam to fully insulate the walls &amp; etc.<br>On a side note, some twenty-something girl hit the bumper of my car at the stoplite this a.m.on the way to work<img src="/images/boards/smilies/frown.gif" border="0" align="absmiddle"> Not too much visible damage.<br>Thanks in advance!<br><br>

<font face="Times New Roman" size="4">Be careful with the spray foam.&nbsp; It expands a lot, and can bulge body panels.&nbsp; For example., if there's say a cubic foot of space to fill, use half of that amount, which will then safely expand without doing any damage.&nbsp; <br><br>I used reflectex to line the interior walls, then sheets of R-12, and then spray foam in small boxed in areas.&nbsp; <br><br>For hard to cover areas, you could glue matching upholstery material to the reflectex and then glue the reflectex to the walls. </font>&nbsp;&nbsp; <br>

I've never used the stuff before. Can that spray foam plug holes and keep critters out?&nbsp;<div><br></div><div>I read about how mice find their way into travel trailers/RVs when looking for warm places during the winter. I'd like to apply it to my rig as a preventative measure.</div><div><br></div>

<div><br></div><div>Filling voids and the leaks they cause is the primary purpose of the product. &nbsp;If your vehicle is anything like my last one, you will have a hard time getting to their favorite holes.</div>

Filling voids and the leaks they cause is the primary purpose of the product.

<div><br></div><div>Yeah I get that, but can it prevent them from getting back in. Or to be precise ... can they dig right through the stuff after it hardens.</div><div><br></div><div>

<div><br></div><div>No, not in the slightest.</div></div><div><br></div>

I have never known a field mouse to chew or dig through anything that they can go around.

<div><br></div><div>Exactly. However the foam would presumably fill in not only the hole they made, but everything behind it as well. So if this stuff is chew proof or at least a strong chew deterrent, then even if they bust through a new spot the foam behind it should put an end to their digging. Right?</div><div><br></div>

I've used foam to deter mice from entering between drainpipes in my house, &amp; they've NEVER gotten back in, thus, my mouse problem vanished.<br>To answer my own question: I've located a website that a contractor says that sprayfoam, albeit more expensive than its' counterparts,&nbsp;has a higher R-value.<div><br><a target="_blank" href="http://www.askthebuilder.com/565_Foam_Insulation.shtml">http://www.askthebuilder.com/565_Foam_Insulation.shtml</a><br><br></div>

Just the answer I was looking for ... Thanks xi700!<div><br></div>

<font size="4">make sure to use closed cell foam, open cell absorbs moisture- think sponge......</font><br>

One other thing too, Dow's website makes mention that Great Stuff Foam is good for keeping out pests.&nbsp;<a href="http://greatstuff.dow.com/" target="_blank">http://greatstuff.dow.com/</a>

I dunno about mice, but squirrels love spray foam and fiberglass insulation.
