1.Low thermal conductivity: Rubber and plastic products have a very complete closed-cell structure due to the process, so their thermal insulation performance is particularly good, which can keep heat and cold. Few thermal insulation materials can keep both heat and cold like rubber and plastic products, so the application range of rubber and plastic products is particularly wide. Excellent thermal insulation properties make rubber and plastic products very hot in the market.
2.Good fire resistance and flame retardant performance: Because its raw materials are pvc and nbr, rubber and plastic products determine that it is fireproof. Most rubber and plastic products are classified into B1 and B2 grades, and a few can reach B0 grade.
With competitive price and timely delivery, Decai sincerely hope to be your supplier and partner.
3.Vibration reduction and noise reduction: The sponge-like structure of rubber and plastic insulation materials makes it highly elastic, has the function of reducing vibration and absorbing noise, so it can minimize the vibration and resonance of frozen water and hot water pipes during use.
4.Long service life: rubber and plastic products have long working life because its good weather resistance, anti-aging, anti-severe cold, anti-heat, anti-drying, anti-humidity, anti-ultraviolet, ozone resistance, non-deformation. And it&#;s soft, stretches well, and is suitable for use in many places.
Rubber and plastic products can be widely used in various heat and cold places in air-conditioning pipes, building construction, ship insulation, electrical appliances and other industries. The construction is convenient and the installation is simple. In addition, we often see that the handles and sheaths on fitness equipment are also made of rubber and plastic products.

I am planning my van insulation. When I checked Home Depot and Lowes foam boards, I was surprised. Where are they? I almost can only find EPS, and a few XPS. But the price of XPS are super high. I could not find polyiso. What is wrong with insulation boards? Where are they?
There have been shortages on and off.
Have others found shortages of Polyiso foil backed board and two gang plastic old work boxes? There are none of either in both our local Lowes and Home Depot. Regards, Mark
My local Home Depot had it s couple weeks ago.
Grab the SKU from a shelf label or the website and use Brickseek to see if it's at stores near you. It's faster than their website and tells you how much is in stock:

I found polyiso on Home Depot. Multiple thickness available.
Yes, I want XPS as I live north. But the price is much higher than before. No 1/2 inch now. I am planning to use 1.5 inch for floor and walls, 1 inch for roof, and 1/2 inch for windows besides my rear bed.
Go to a packaging supplier and get P.E. packing foam board. (Charcoal grey, or white) It is flexible, conforms well, has the same R value as urethane foam and a 4.5' x 9' sheet of 1" thick is about $35. Contact cement will hold it in place and it is a better sound barrier than hard foams....
its been long years since amazon (I think) started the trend that it is cheaper to send from the warehouse, than deal with keeping up big warehouses like HD with lousy employees trying to keep them in order.
You can still order lot of materials, when on big order they will deliver for free to your home, or on small orders you can pick it up at local HD without shipping charges. I ordered 1/2 " polyurethane foam to make window covers from it, when lot of other sizes are available
The PE, (poly ethylene) packing foam is closed cell and about R7 per inch, also cheaper.
If you wanted great sound deadening, you could glue an inch to the larger metal panels, then an additional 1/2" of the heavier rubber foam as the inside layer. Varying densities is best for sound barriers.
I carefully filled behind all the pillars and beams with spray foam. You can use the spray foam to fill the voids between the foam board and framework.
I would check the posted R values for PE packing foam. Most of the stuff I see is lower grade, and has quite large cell size. So the R value is rarely higher than ~3. Even the best PE foams I have seen top out at R4 or so. I have never seen a common grade of PE foam thats R7. Even polyiso which uses a low E blowing gas, (as opposed to the air in PE or EPS), is only R7 or so.
Polyethylene Foam is an inexpensive antistatic foam excellent for packaging material and for cushioning of sensitive electronics. Antistatic Packaging Cushion, Polyethylene Packing Material, Anti Static Poly
Neoprene rubber sheets are typically similar.
Not that soft foam sheets can't work, but they will have a fair bit lower R value, which can be significant depending on how good your insulation job is, and what climates you operate in.
Typically EPS is the best bang for the buck in rigid foams, at least for areas that get cold. In hot only usage, polyiso tends to have better performance, at least until the blowing gas bleeds out (takes about 7-15 years).
Thank you! That is a good option. I am also thinking to use adhesive rubber foam. The R value should be 4 per inch, but good at sound deadening too.

--lol. Looks we were looking at the same product.
Another choice is Aerocel closed cell foam insulation. Used by breweries for tank and piping insulation. Should be available locally.
I used it in the cubby holes and on curved surfaces.

A closed cell 2 component spray foam (higher density if possible) will work under an RV, and several coach builders use such products. In general they should be painted with a compatible paint, to prevent degradation from reflected UV. You need to stay about 6" from the exhaust generally.
For under a vehicle, I would use XPS or EPS boards where possible. I like the EPS with plastic film for addition protection. Obviously remove the film on the side to be bonded to the floor. EPS/XPS doesn't need any additional coatings for UV protection.
The main concern is flying debris eroding the foam, which can be an area exposed to thrown rocks/sand from the wheels.
Polyiso can absorb moisture more readily than EPS/XPS, and generally isn't well suited for this environment.

Seems the options of EPDM foam sheet are not so many. Didn't find any big EPDM foam sheet with adhesive. I compared s few cheapest PE/EPDM(non-adhesive)/neoprene foam sheets. I may end up with PE because the price and easy to use, unless find an easy EPDM adhesive solution.

Aeroflex sells an adhesive to glue the sheets to the van steel and to another sheet. No need for a sheet with adhesive. I used 1" and 1/2" thick closed cell foam. Two 1" thick layers in the cubby holes above and below the window indents and 1 1/2", 1" or 1/2" on the curved parts of the roof. Adhesive was easy to apply and use. Just apply adhesive to both surfaces.
