We are planning on putting a little more insulation in our bus by "stripping" the walls and ceiling with 1/2" osb strips, on about 18" centers, with the foam insulation board in between. We plan to cover it all with either luan or some other lightweight material. Our question is, what is the best adhesive to use to attach the luan to the osb strips? Will F-26 be good enough, or do we need something heavier? I have seen you all talk about Sikaflex, but I can't seem to find it (at least under that name brand) at Lowes, HD, etc. Any suggestions would be appreciated. | ||

Get a Defender Industry Catalog (in CT) and there will be loads of goodies from epoxy to glue to hardware used on boats. They have an 800# and the catalog is FREE. Standard type 3 wood glue is as strong as epoxy and 1 /10 the cost. Spread the glue on both surfaces and use a pin nailer or a screw to hold it till the glue sets overnight. FF | ||

Why OSB? It makes lousy furring strips, it stinks for a long time, and it flakes and delaminates easily. If you use 1/2" stock, get some fir or SYP five-ply (if you can find it) or four ply exterior rated plywood. It will glue very well, it will stay together, it won't sag between attachments, and it won't split everywhere you screw it to the framing. Normally, two inch strips work best, with two screws or rivets at each frame; then it won't twist or curl. | ||

I'll second Don on this, OSB seems like a poor choice. With plywood or pine you could use Elmers wood glue or a liquid nails type product with no fear of failure. Only my opinion of course!! I used thin luan on the walls in areas of my bus. Make sure to plan ahead and have furing strips or place blocking behind luan anyplace you want to mount something valances towel racks (another reason not to use OSB) In the kitchen area I gave up and used 1/2 in plywood, too hard to figure all the cabinates etc. The radius of the ceiling was done with luan, but where there are overhead cabinates I used sheet metal behind the luan to have something to fasten to, This could also be done with proper placement of furring strips, maybe even 8 inch centers.

I agree, OSB has its uses but what you are considering to do with it, I think you will have issues. I also would use normal plywood, the cost will not be that much more, but you will not have to worry about it warping and falling apart over time. Jim | ||

I agree on not using OSB. I used 1 x 1-1/2, ripping some 2x4s and installed @ 12" O/C. Then used 1" high density ridged insulation. Going to 1" makes it easier to install electrical boxes in your exterior walls and the added insulation is great for sound barrie, well as temperatures. Ron | ||

The riged insulation is a good choice. I glued it to the coach and sealed the cracks with expanding foam. Then glued the luan to it( plus screews). Since the luan is so thin a firm baking helps keep it from having any waves. | ||

Hi Buddy Why not spray in foam and good 1/2 plywood.Then you can hang anything any where.You will change your mind as you go along and have to take the thin stuff down to brace up the walls.Then you can put anything on the walls.We used light weight vinyl and naugahide. Good luck ole-timer | ||

The "best"insulation is simply sprayed in place HOT buy a pro . Second best is the foam boards glued in place. However if the origonial glass insulation is still in the vapor tight bag , the difference between it and the "best" would be hard to notice. Chipboard even in counter tops is a poor choice for a coach , for walls its a REALLY poor choice! FF | ||

FWIW, we used mostly 1.5 inch foam insulation boards throughout...(in some places used two 3/4 inch and/or 1/2 inch) boards if space did not allow}. Did not use glue for the side panels...just let them float; but they were "cut to size" so all fit tightly. As I remember I did "glue" the ceiling pieces, using PL....also fit tight, but the final ceiling is 1/16th oak Plywood screwed to the cross members which, of course, hold everything in place. Sidewalls have 1/2 inch plywood floor to ceiling,over the insulation, screwed to the upright steel members; 1/16th inch oak plywood over that. All cabinetry, etc. is screwed directly to the sidewalls and to the upper cross members. Seven years later, no regrets. Having said that, it gets HOT in the coach under the desert sun. 100 degrees is not uncommon as it sits from day to day without running the A/C. But then, we have lots of glass....the culprit.If we did it again, I would do without some of the "picture windows"...  RCB | ||

Either awnings on both sides , or the "Southern Cop Sunglasses " style mirrored product will help. Folks usually think of the awning on the patio , but both sides of the camper get hot. A white on white roof and sidewalls helps too. FF | ||

It's all trade-offs. We have awnings over all our windows. As FF said it makes a big difference when we have the awnings out, BUT, it also makes it much darker inside the bus. Our bus is mostly ultra white with only a few fire engine red stripes on the sides. Not as fancy, but helps with the cooling. Our biggest source of heat seemed to be those big windshields. We had covers made for them and that also helped. Jack | ||

Is there any feedback out there for Sam's Town Campground in Las Vegas? Going to Sin City in late September, and was warned off the other campground at CircusCircus. Thanks in advance. Mike in GA |
