Home Depot was very accommodating. I cut each of the 4' x 8' R-Max sheets into four pieces, each 2' x 4' right in their aisle. That way they would fit into the CRV. I did one of the pantry cabinets last night.

I have two identical pantry cabinets side-by side in a slide-out. I am doing one with the R-Max insulation and leaving the other without insulation. I have thermometers set in each one. I will be recording the results as the temperatures outside rise. We will only be getting up to 85 F today but later in the week it will get up to 95 F plus. So I should be able to get a good test.

The left picture is with the drawers removed for insulation installation and the right one is with the drawers put back in. Same cabinet.

The last picture is of a pantry cabinet that has the back and top done. No fasteners used, it fits tight (did it about a 1/2 hour ago). Rmax R-Matte Plus-3 - 1/2 in. x 4 ft. x 8 ft. R-3.2 Polyiso Rigid Foam Insulation Board-754404 - The Home Depot

They don't show a price on this because it is not available at our local HD. Can you tell us what you paid for it?

Yeah, I use two of those for our closet doors. I thought you were talking about some kind of flexible fiberglass tent poles that would bed to conform to the curve of the skylight!

It is a bit hard to find it. Of the four Home Depots in our area only one had it in stock. It is $11.26 per sheet.

I am doing the pantry cabinets as we speak. I've found that it cuts cleanly and easily with a serrated edge steak knife.

I put the Reflectix in one of my wall cabinets that is on the hot sun side. After checking for several days it is about 5 degrees cooler than the cabinet that does not have it.

Thanks for the update! I haven't had a chance to do mine but I think that's the way I will go!

One question. Did your cabinets have a wood back or do you just see the wall board?

Test results: Rmax Plus-3 Polyiso Rigid Board

Summary: The largest temperature difference recorded was 15.1 F.

Methodology and observations:

I tested my Rmax Plus-3 cabinet insulation last Friday, Saturday and Sunday. High ambient temps for those days were 89 F, 90 F, and 92 F. The two test cabinets were both in the same slideout, with the slideout out and same exposure to the south and with the same exposure to sun and outside temperatures. One had the Rmax installed in the back wall and ceiling and the other had no insulation added.

Each cabinet had it's own thermometer which I recorded both temps approximately every hour throughout the daylight/heating portion of the day. In addition to the two cabinet readings I took the temperature reading inside the RV (one AC was running during the tests) and the outside ambient temperature all at the same times.

The greatest temperature difference recorded was 15.1 F:
-Ambient 87 F
-Interior of RV 75 F
-Insulated cabinet 80 F
-Uninsulated cabinet 95.1 F

Other large temperature differential recordings ranged from 14.0 F to 14.7 F, for example:
-Ambient 86 F
-Interior of RV 75 F
-Insulated cabinet 79.8 F
-Uninsulated cabinet 94.5 F

In the past I have used Reflectix on my RV windows and have installed it in areas where I was reflecting heat back out to an open air space. Like a lot of people, I also use reflective insulation in the windshields of my vehicles to keep the interior temps down. This works well, as the heat is reflected back through the glass into the open air space.

Here are some of my observations from installing the Rmax Plus-3:
-Rmax Plus-3 is marketed and sold to contractors and builders for use in commercial and industrial and some residential buildings. Thus it will probably be found only in builder/contractor supply centers.
-Rmax is polysio not styrofoam or polystyrene so there is no clingy, white residue from cutting.
-RMax cuts cleanly and easily with a sharp serrated steak knife.
-I took extra time and care in measuring and cutting so that the Rmax fits in to place snugly without fasteners or glue.
-Since Rmax comes in 4'x8' sheets, I cut it into four pieces so that it would fit into a CRV.
-Cost is $11.26 per sheet at a Home Depot if you can find it there.

Disclaimer: I did the test only for my own benefit and also as information to benefit anyone who uses iRV2.com as a resource. I have no connection to any of the insulation types, brands or stores mentioned above.

Typical test setup: Insulated cabinet on the left and uninsulated cabinet on the right. Pictures taken at the same time.

Thanks for the info! That's making me rethink my decision to use Reflectix!

aauummm, In your temperature test what was the thickness of the R-max you used to insulate the cabinets?

Safe travels and THE JOY IS IN THE RIDE

I purchased the 1/2" thick stuff. I was intending to use one layer and did at first. Later I realized that I had about an inch of clearance behind some of the drawers so I went back and put in another 1/2" for a total of one inch in some places.

I did the same in the ceilings. At first one layer and later figured I could get in two layers without sacrificing space, so I did. I have some odd pieces left over so I'll cram them in where ever I can.

In the uninsulated cabinet I have no drawers so space will be at a premium. I will probably go with just the 1/2" and test it. If it needs more, I'll just have to do with the space left.

Safe travels to you too and I agree, the journey is the destination and I savor every minute of it!

MS-you're welcome! It all can be very confusing, that's kind of why I did the testing-to give me some data to go by.

I'm going to try to stuff some more of it anywhere I can but my other cabinets have drawers in them that make it almost impossible to get to the back of them.

I'm pretty motivated to go after the heat-I've gotten caught in 105+ F weather a number of times and once in 113 F with no shade. That was rough, I even tried spraying water on the roof to help cool it down!

This is good information and you have given me another project to do. I need to look behind the drawers, perhaps pieces can be put in with some spray adhesive.

Have you done anything with the front overhead cabinet? That gets really hot up there and I was wondering if this would help there too. Thanks for the tips.

Before installing any foam type insulation in an occupied space, such as inside a motor home, that foam is highly flammable, and emits highly toxic smoke should it burn.
Remember the fire at the Monte Carlo Casino in Las Vegas a few years ago. Fire was burning rigid insulation board.
