Block Foam for insulation for underneath trailer?

Hi all,
Just wondering...has anyone insulated the underneath of their Escape trailer with block foam insulation such as 2 inch thick R-Tech used in houses? I am looking at ordering a 17B for 2017 and thought I'd look for insulation options under the trailer other than the spray foam. That stuff is hard as heck to get off if you ever need to access anything under it. Thanks!

I've looked at mine with the same idea in mind. A good percentage of the underside (at least on the 19) is smooth and flat and it would be really easy to attach foam in those areas. That area is also conveniently under the area inside that you walk on. Haven't had to need for it yet but if I was considering using it in the winter or really cold weather I'd put it on in a flash.

I'd use foam adhesive but also run a couple of fore and aft metal metal straps as backup for the adhesive. I know, belt and braces, but that's just me.

My thought was to use one inch wide Velcro strips glued to the fiberglass and foam. I do see on some of the RV blogs that temps will often get below freezing in Arizona, etc. So I thought the extra insulation would come in handy until it got below freezing for days on end. Hopefully by then I could move to a warmer environment or just drain the tanks.

Arizona is unusual in that the northern part may get over 100 inches of snow but the southern end may be very hot. RVers there in winter are at the southern end, or should be, and should not have much of a problem with freezing. Anyone who stays in a spot a long time with freezing temps will skirt the trailer. That can keep out cold air much better and probably easier than trying to cover the bottom.

If adhesives securing a solar panel roof rail can break loose, any adhesive can fail. Why take a chance using it at the undercarriage, where it be subject to stressful pounding and wear due to vibration, road gravel, wet-accelerated road weather? Seems to me a common sense tipping point favors a cup of tea, and a nice rug.

How about using some interlocking polyurethane floor tiles inside the trailer with a carpet cut to fit for the wintertime? Then when summer rolls around you can pull it out and stow it.


Anti-Fatigue Foam Mat Set 4 Pc


This scheme gets used on boats sometimes by people who live aboard boats during the winter.

The cross pieces of the frame lend themselves to attaching some metal bands running fore and aft. If the adhesive failed the metal straps, much like the water tank straps, would still hold the foam on.

Nice rug

We carpeted with Flor tiles which are insulating. They did as much as the insulation underneath. As to the discussion about Velcro underneath...Velcro is extremely difficult to "glue" even with 3M's high strength adhesive. Just adhering strips to the window frames has been a challenge.

3/8" of cork on the floor sure added to the warmth and comfort.

My main concern is the water tank being exposed. I'd like to at least get that covered in block foam or something similar for cold weather. And the carpet, mats and cork floor ideas for keeping the floor warm/insulated are certainly worthy of consideration. Anything IN the trailer and on the floor would have to be durable and cleanable due to traveling with a dog. He hasn't quite caught on to wiping his paws before coming inside.

By the way, that's a nice rug.
