What is the R-value of ASTRO-FOIL?
Using standard
test methods and scientific model calculations, the R-value could be as
high as an R-29 but will vary dependant upon the application and the
direction of heat flow.
R-value Calculations.
If you install
two layers of ASTRO-FOIL will you double the R-Value?
No. By placing two layers together, you will still only have one
reflective surface. The only additional R-Value you will achieve is the
additional R-Value of the bubble layer itself, which is an R.5.
Why do I
need an air space next to the ASTRO-FOIL or R+HEATSHIELD surface?
When aluminum foil is in direct contact with another surface, it
conducts (or transfers) heat at the points of contact. Creating an air
space will prevent conduction and allow the foil surface to reflect
radiant heat. Aluminum foil reflects 97% of radiant heat.
Does ASTRO-FOIL itch like fiberglass insulation?
No. ASTRO-FOIL
is manufactured out of polyethylene film, air bubbles and 99% pure
aluminum foil. There are no irritants or fibers. Astro-Foil can be
installed without the hassles of protective clothing, masks, gloves, or
special tools.
Do I need special tooling to install ASTRO-FOIL?
No. ASTRO-FOIL
can be cut easily with a razor blade or scissors and installed with
common staples, nails or screws.
Do I need to tape the seams?
To achieve an
absolute moisture barrier, taping the seams is recommended.
All of the equipment in my metal building is getting
damaged from condensation drips. Do you have a product that can help?
A variety of
ASTRO-FOIL, R+HEATSHIELD, and ASTRO-BOARD products will reduce, if not
stop your condensation problem by creating a buffer between interior and
exterior temperatures.
Can I install R+HEATSHIELD by myself?
R+HEATSHIELD
is a perfect do-it-yourself product to enhance the current insulation in
your attic. It is lightweight, easy to install and will reduce energy
consumption.
I am installing a radiant heat system in my new home.
What insulation should I use?
Staple ASTRO-TAB in the joist cavity under your radiant flooring
system to reduce hot spots, prevent downward heat loss, and decrease
boiler loads. Install TUFF-STUFF under your concrete hydronic floor
system to achieve a moisture barrier and thermal break that meets
manufacturer requirements.
