question: Hello: I am an engineer at ------------- in
-------. I do HVAC system design. I would like more
information on Radiant barrier technology CALCULATIONS. I
need to be able to show clients how I come up with the
energy savings using this technology. Without the scientific
backup, it looks like "smoke and mirrors". Where can I find
useful data.

question: I have an existing pre-fab metal building. It
is 24X36 with 12 foot walls. I am looking for some ideas on
retrofitting it with some kind of insulation.
the primary need is the roof, or ceiling. It has purlins
on 4 foot centers. I am interested in astro-foil, and need
some ideas on installing it without removing the metal
siding.
for instance screwing some 2 x 2 lumber into the insides
of the purlines, and then stapling the foil to the lumber.
How much sag would I have if I were to do this? Am I going
to have trouble with the staples wanting to pull throught
the foil?
any help that you can provide is appreciated,
thanks,

question: What is the R-value if it is installed on the
underside of rafters in a cathedral ceiling? The air
space/vent will be between the foil and the ceiling. Is
this an "apparent" R-value or a true R-value that will
satisfy a building code requirement. (Code in my area
requires R-19 for roofs).
