<< A few follow up questions on Robert's small building:
1) Could you describe the R-23 "compound" insulation? Standard
fiberglass bat, extruded styro, sprayed on foam? I'd like to hear
more about what you used and how it was hung.
2) Likewise the "high tech" roofing - what is it and how applied (the
peel and seal stuff you mention on the webpage you attached) ? Is it
something that has a track record of longevity/weatherproofness with
you or are you just trying it out?
3) On dissassembly and reassembly elsewhere - if this is a hub and
strut unit, where does one break the shell when its time to take it
down, and what's the general procedure at reassembly if one want's a
sealed roof again and reasonable moisture barrier for the insulation?
Any particular fasteners best - drywall screws, bolts, lag bolts...?
I'll be interested in your photos.

The compound insulation consist of Reflectix reflective bubble
insulation combined with Cellutex board insulation installed between the
framing and the sheathing. The Reflectix has an R-15 in the summertime down
direction and the 3/4" Cellutex has an R-8 value when properly installed. A
typical installation is shown under the "upgraded fabrication" link at:
The Peel & Seal has been around awhile but my experience has been limited
to around 5 years. It goes on easily, has a factory warrantee of 10 years,
and I have experienced no leaks and expect none. I also expect that it will
last a lot longer than the warrantee.
It is a flexable lightweight roofing with a sticky backing which is
lined with waxed paper which must be removed to install. It generally comes
in white, silver, or grey with the silver being the best in reflecting the
solar heat and therefore having the longest longevity and energy efficient
The structure is a paneled dome with the flexable roofing encapsulating
the sides of the panels, therefore sealing the sheathing and insulation. The
panels are simply bolted together and for a more permanent roof, 6" Peel &
Seal stripping is used to cover the seams with the top edge of the seam being
further sealed with 35 year clear caulk. What I used for a more temporary
solution was to seal the seams was use Asto Foil aluminum tape. It cost
around $5.00 for a 500 foot roll. I also sealed the top edge of the tape
with the clear caulk. By using the Asto-Foil tape, it is much easier to
break open the seam and dissasemble and you don't wind up with a raised edge.
JMR was sent a photo of the finished dome for the domehome WEB site, but he
is on a business trip and won't post the photo until next Wednesday. I have
photos of the framework without sheathing being assembled during the first
field test. It is on the /dometruss WEB site under the 14' dome link. The
bolts used for connecting the panels were 3/8" , 16 thread, 4 1/2" bolts. I
used 3" coated deck screws for holding the individual framed panels together
and 2 1/2" coated deck screws to hold the sheathing to the framing. Bob
