Underbelly Material?

A visitor tried to make a home in the bottom of my trailer. This was some time ago, I think when the prior owner had possession.

I can figure out the insulation, but what is the fabric covering the insulation called? It's not Coroplast. What is an acceptable substitute?

Looks like a woven polypropylene to me.

Thanks. Any reason why you went with the Surface Shields product instead of something else? I was looking for something a bit wider than 4" but that width would be acceptable.

Thats what I found at the time plus I could overlap and have different lengths as needed with little waste. If you look down the amazon page there is different sizes but for the price the 4" long oll was a better deal for the long run.

Sounds good. The Flex-Mend also has good reviews. I was hoping to find a local retailer than carried either one, but it's not looking good.

In the picture is what historically was called "belly wrap" it predated Coroplast. You might search for it online under that term and see what comes up. I used to order it from All-Rite. I think this is it Underbelly Material.

The "fabric" looks like poly weave of some form. As other suggested Truck tarp or even tarp itself. It also looks like the some stuff sand bags are generally made of too.

Corogated Plastic or coroplast is used in the sign making industry. Common size is 8' by 4' sheets and usually 3/16 inches thick and is white inc color. Price will range around $8-20 a sheet. I have seen it sold in the home improvement stores like Home Depot but not Lowes then again I was not looking there. I stumbled on it at HD since I was there for 3/4 inch MDF for a shop project. I digess.

Best bet is if you are going or wanting to close in the underside, find a local wide format graphics supply. A place that will sell by the sheet. It should cost in the 7-11 range. If you don't have anything close try a sign shop. They will probably have a smaller piece for a few bucks. They might be able to get you the sheets you are looking for. Don't know. I know the stuff we handle in work. We deliver to our customer base. We have a couple of guys that will come in but they will pick up thier sheets of coro.

I did end up with the Flex-Mend. I went through an entire roll of 28"x14' and then most of a roll of 4"x180'. The Flex-Mend isn't as thick as I expected, nor is it as sticky as I wanted. Getting the material to release from the backing was very difficult until I read the instructions on the 28" roll and went through a lot of tape. Now I can release it quickly. The trick is to use the flat part of a utility knife to distress a corner of the tape. That will make it release from the backing material.

Working with the 4" roll is easy. The 28" roll can be very challenging. The backing material had a tendency to tear and not release. Trying to get to a piece of backing material in the middle of the sheet while laying on your back with minimal room was not fun. I did the 28" roll by myself. A helper would have made it a lot easier.

I hope that it holds up. I used it to cover up insulation on my fresh water tank and then also to seal up some holes in the belly fabric where critters had got in.

That sounds like the kind of job that would require a lot of swearing!
