Home Insulation - Astro-Foil in Residential
Applications
Aluminum foil reflects 97% of radiant heat and only emits 3% making
it an excellent material to reduce radiant heat transfer and meet your residential
insulation needs. ASTRO-FOIL reflective insulations and R+HEATSHIELD radiant barriers
are made with 99% pure aluminum foil. Using these residential insulation products
in the applications below will provide extra energy savings:
- Put ASTRO-FOIL
or R+HEATSHIELD
as a radiant barrier in your attic to prevent heat build up during summer months
and reduce heat loss during winter. Your air conditioner and furnace will thank
you!
- Either wrap your house with R+HEATSHIELD
or install ASTRO-TAB
in your sidewalls to enhance the performance of mass insulation by reducing drafts,
providing a thermal break and creating a more thorough building envelope.
- Use ASTRO-TAB
or ASTRO-FOIL
to insulate below your radiant heat floor and you will reduce hot spots, prevent
downward heat loss, and decrease boiler loads.
- Use ASTRO-FOIL
for your Garage Door to keep your garage temperature more comfortable throughout
the year. Don't forget that you can also install it in the walls and on the ceiling.
- Whether you wrap your ducts with ASTRO-FOIL
or line them with ASTRO-SAFE,
you will minimize energy consumption by keeping the air flowing through the registers
not escaping into unwanted areas.
- Line your crawl space with ASTRO-FOIL
to insulate the floor and eliminate ground moisture from transferring to your
living space.
- Insulate your water heater with ASTRO-FOIL
to save energy by minimizing water temperature fluctuation, reducing cycle time.
- We've got the stuff! TUFF-STUFF
under radiant heated slabs will greatly reduce downward heat loss and prevent
moisture transfer. Installers jump up and down over our STUFF. Can't do that with
foam board!

Astro-Foil in Commercial
and Agricultural Applications
Aluminum foil reflects 97% of radiant heat and only emits 3% making
it an excellent material to reduce radiant heat transfer. ASTRO-FOIL reflective
insulations and R+HEATSHIELD radiant barriers are made with 99% pure aluminum
foil. Using these products in the applications below will provide extra energy
savings:

- Install ASTRO-FOIL,
ASTRO-WHITE
or R+HEATSHIELD
over purlins and girts to reduce condensation, prevent heat gain during summer
months and reduce heat loss during the winter.
- Install ASTRO-FOIL
or ASTRO-WHITE
on the bottom of trusses or exposed ceilings to prevent heat build up in animal
confinement and shop areas during the summer and reduce heating costs during the
winter.
- Whether you wrap your ducts with ASTRO-FOIL
or line them with
ASTRO-SAFE, you will minimize energy consumption by keeping the air flowing
through the registers not escaping into unwanted areas.
- Use
ASTRO-FOIL around your Garage Door to keep your interior temperature more
comfortable all year around.
- Use ASTRO-FOIL
or ASTRO-WHITE
insulation on exterior walls in post-frame and pre-engineered metal buildings
to cut energy costs, reduce condensation and prevent heat gain or loss.
- We've got the stuff! TUFF-STUFF
under radiant heated slabs will greatly reduce downward heat loss and prevent
moisture transfer. Installers jump up and down over our STUFF. Can't do that with

Reflective Insulations and Radiant Barriers Dramatically
Reduce Heat Flow Across Open Spaces
Reflective insulations and radiant barriers are characterized by high-reflectance
/ low-emittance aluminum foils mounted on substrates such as polyethylene bubbles
or paper. Low-emittance surfaces limit the rate at which radiant heat leaves a
surface while high reflectance surfaces limit the amount of incident radiant heat
that is absorbed.

The radiant heat given off by a surface at a given temperature is related directly
to the surface emittance. The rate at which radiant heat leaves a surface can
be calculated from well-established mathematical relationships. Radiant heat transfer
across enclosed air spaces is significantly reduced by the installation of a low-emittance
surface to form a reflective insulation system. The results of example calculations
for a typical installation is shown below:
