Bag seal material found possibly

[oldstick]

I stopped by Hobby Lobby recently and they had some vinyl fabric rated for UV outdoors/marine use for $30 per yard if I recall correctly. The roll is 56" wide, so I figured one yard is enough to do the whole seal at the rear roof area, IF I don't mind overlapping 2 pieces across the top of the RV.

I figured 4 strips maximum of 7"x56": two 56" strips along the top overlapping and 1 strip down each side less than 56".

The stuff I am looking into is 61" wide, but I just am not sure about overlaping and having water get in between the two pieces.

Good point about water getting in a seam. But, if one folded-over the overlap, and "glued" the overlap with a flexible silicone (or better material for that) before folding, it should be watertight. Would not want water sitting inside the bag seal.

My wife has a sewing machine, maybe sewed together folded and sealed hmmm, I have a yard, I think I will cut it today and sew it as she has v69 thread and uv treated even for outdoor use.

cut a couple pieces of the material 7 1/2 " wide and will be sewn at 7 1/2 ' long

then was sewed, sealed, folded sewed again an sealed with seam sealer.

I did the sewing not the wife so the crooked stitches are all me. but it will work, hey it was my first time sewing . lol
Going to use this for the rear outer shell top seal. and coating it with 303 areospace UV protectant.

If anyone wants to purchase a couple of pieces this size I will sell it for $5.00 plus shipping for a 7 1/2 " wide and 7 1/2 ' long I can sew it or you can sew it. sewing will be extra $ 4.00 Sewed stitches will be straighter

What are you using inside the seal for the foam?

I have not removed the old bag seal yet, but if I need to replace the foam, which more than likely will do anyway, I was going to use a open cell foam

Possibly from this place : http://www.foambymail.com/HDR_1/hd36-regular-foam.html

As I started this removal of the bag seal today, DW showed me the foam she has new from when she upholstered our class A so I now have foam!

My question would be the uv rating

I got like 50" from TM last fall, plus the foam they use. I think delivered it was like $100.

I contacted the supplier myself, I was told that if it had the FR it also had the UV treatment done at the same time. So I am thinking it is good to go.

The place I bought it said it was FR treated but was not sure if UV, he then called me back and said no UV. I found that the material came from value vinyl and they tell me UV treated when FR was done.

I am going to treat it with the 303 UV protectant but I am not too worried about it now.
