Eggs and Insulation

Had occasion to cut hole in my '91 Scamp 13', so here are photos of the standard insulation and headliner, which is on all walls and ceilings, but not the door (headliner only, but the door also has a layer of what seems to be plywood in it).

The insulation is double bubble and double foil and is 1/4 to 3/8" thick (air pockets on outside) depending on where you measure it. The headliner is 1/4" thick (and the fiberglass roof is 1/8" thick), and the Scamp Manual says it is about R15.

I apologize in advance for the poor focus on the one shot.

The curtain rod is merely a wooden dowel, secured by two kayak deck fittings screwed directly thru the headliner to the underlying wood with short (so they don't penetrate the outer fiberglass) wood screws. The curtain itself is one of a part set of kitchen window stuf (note technical home ec term) found at WallyMart).

Good report

Good report and pictures Pete ... but I gotta ask ... why did you have to cut out that big of section? And how did you do it?

Insulation: Scamp vs Casita

Is the Casita insulation pretty much the same as the Scamp insulation? My unsubstantiated suspicion was that the Casita might be more insulated. Does the Scamp or Casita have a cold floor?

Charles-I cut that section out of the roof to install my fantastical fan that I have been carrying around in the back of my truck for some time now. I finished up in the dark last nite (the sealing part; still gotta fish the power and put on some nice wood trim), but I finished, which was a good thing because it rained early this morning.

I hope to cool the interior down more quickly in summer, vent cooking vapors (it lines up pretty well so air can come in over the range and go up and out) and vent moist air in cold conditions.

I used my friend's neighbor's SawZAll, but maybe an electric jigsaw would have been better. Certainly should have had someone standing there with a vacuum cleaner by the cutting; I'll be itching for a while...

Mary, the stained glass decal was on it when I bought it used in Vermont. Last I heard, my old Jayco was a Used Car Lot Office near Montpelier, but it wouldn't surprise me to find out it's now a Hunt Camp (had plenty of ground clearance).

Benita - I dunno what the Casita's wall/headliner Rvalue is; maybe someone can post it? The Scamp is "about R15" according to the manual. On the floor, the Casita has the fiberglass under the flooring, so I would expect that to make a difference esp in a cold wind, but the upper insulation is what traps the heat. Leakage around the exterior door and cold moving from the cabinets/closets/ refrigerator openings, etc., will create drafts in all the Eggs.

I just saw the double bubble with foil on both sides at a lumber supply place today; $2.49 per lin ft in 48" width, called Reflectix.

I expect that the foam insulation found in the Bolers, etc., has a pretty potent R value, esp if you then glued on headliner like the Scamp has.

Pete and Rats wondering why there's a new light in the sky
