that is correct

Reflectix and similar products have an R value of 1.08. Reflectix - 'the company advertises the R value when measured in a system, I.e. With an air gap.

Do not pay to much attention to the reflectix site data, perhaps wander on over to greenbuildingadvisor.com and check out the many discussion on reflectix as a duct insulating material.

Probably enough discussion on this, as there seems to be some entrenched positions, and that is okay, just nothing to be gained by furthur discssion.

Tomorrow at 10:00 ish, going to have a phone discussion with Oliver. The answer to my question was they use reflectix, lizard whatever, thinsulite, and I think a 3M honey comb product -more later.

From earlier readings of the Oliver trailer... they use LizardSkin. I'd be intererested if something has changed with the boost in new production.

Robert at Oliver

Had a very nice and informative conversation with Robert at Oliver.

The 22 foot is not only longer but wider and taller, not sure of the exact dimensions.

They have used lizard skin Donna, on one unit they used lizard skin on both the outer wall of the inner unit, and the inner wall of the outer unit - I just had to make that sentence as non-understandable as I could

Not doing that now in new production - they use 3M thinsulite for insulation, near and dear to my heart, as that company pays me monthly. Their supplier, supplies the thinsulite and adhesive to adhere it to the fiberglass shell. Now depending on the weight of the thinsulite, it might have an R value around 4/inch. Now fabric folks do not measure R vales, they measure CLO, which takes many things into play, body transpiration, etc, but 1 CLO is pretty equivalent to 1 R value.

They also use a honeycomb laminate in the molding of the shell, and that also has an insulation value, probably just above 1 per inch.

They are looking at reflectix, and hopefully not using it, if they want a radiation barrier aluminum foil is a good substitute - maybe.

More later, hopefully

Very interesting, thanks for the feedback Chuck. Let us know when you head down south and pick up a brand new Oliver

Their dimensions are on their website, here Specs & Floor Plan - Oliver Travel Trailers
looks like 6"2" wide interior and 6' 6" wide exterior and 6'1 interior height.

A 6' 6" wide exterior will not likely be wider than the earlier model... it is narrower than an original Boler! Did anyone keep a record of the original 17-foot Oliver specs?

A longer trailer is typically taller if only because the ends must be higher for ground clearance. A longer trailer's frame is also typically deeper, for strength, pushing the height up further.

Now, if only I had more faith in dimensional information published by manufacturers...

(A different manufacturer continues to publish that their crosswise bed is as long as the outside width of the body, indicating that there's no curve in the body and that the walls have zero thickness... even after the impossibility was pointed out to them and acknowledged.)

Information is good. Lack of information is not so good, but misinformation is much worse. Check facts, and apply common sense liberally.

That seems reasonable for a soft foam: higher than fiberglass batting, but a bit lower than polystyrene foam.

That's R-4 per inch of thickness: does anyone know how thick it is? For instance, a quarter inch thickness would provide R-1 of insulation. At that sort of thickness it would be similar to the foam-backed liner used by Escape. We're not talking house levels of insulation here...

Insulation thickness

Bob said that the gap is about 1 to 1.5 inches. Also headroom about 76 inches, and I think 84 inch width. (maybe 86)

It's hard to understand wasting that much interior space... but okay. Still, it seems unlikely that they are filling that with Thinsulate, but I suppose they could be... or they could be putting a thin layer of Thinsulate on the shell, and leaving an inch of air gap.

That width makes more sense, and is similar to some of the old "widebody" designs such as my Boler B1700.

The original Olivers had (according to their brochures) an outside width of 6'6" for the 17' models and 6'11" for the 22 foot models (both sport and elite). So either their current website is wrong or they have reduced the width of the 22' model. I'd guess that their website is wrong, but they also seem to have changed the outside height to 8'7"(current site) whereas before the 22' model was 8'6" (interior height 6'6") and the 17' model was 8'4" in outside height.
