Reflective Insulation

Improves Interior Comfort

AstroShield, an improved version of the product previously known as Astro Foil insulation, is a line of reflective insulation featuring Polyethylene bubble film sandwiched between two protective sheets, one or both of which are composed of a strong metalized aluminum polyester film. This Foil Insulation film provides a reflective surface that blocks up to 95 percent of radiant heat, dramatically improving thermal performance and energy efficiency while keeping energy costs lower and interior spaces more comfortable.

Mass insulations like fiberglass, cellulose and foam merely slow down the transfer of conductive heat by absorbing it; they do not reflect radiant heat away. Like a radiant barrier, reflective insulation is a highly effective barrier to the transfer of radiant heat. The middle layers of bubble film give the structure added strength and provide a thermal barrier against conductive heat transfer.

AstroShield FAQs

Q: What types of applications are appropriate for AstroShield?

A: There are many applications for the building insulation industry (e.g., residential, industrial, commercial, agricultural, metal building and pole barn). In addition, since our foil insulation is thin and lightweight, it's ideal for OEM applications to control temperatures in any space-constricted situation (such as in a recreational vehicle or inside machinery that requires temperature control in order to function properly). Used as an insulated packaging material, our products not only provide excellent thermal insulation performance for shipping or transporting temperature-sensitive items like food, candles and pharmaceuticals, they also help our customers save money on shipping and warehouse expenses because they are lightweight and less bulky than other forms of insulated packaging such as Styrofoam.

Q: What is the difference between AstroShield and AstroShield WHITE?

A: AstroShield has a reflective metalized aluminum film on both sides, and AstroShield White has one reflective side and one white side. For some applications, it's desirable to have just one foil reflective side. In addition, we offer versions of AstroShield and AstroShield White with one layer of bubble film or two layers of bubble film (double bubble insulation); the second layer of bubble film is associated with a higher R-Value.

Q: What is the R-value of AstroShield?

A: Using standard test methods and scientific model calculations, the R-value could be as high as an R-29 but will vary greatly depending upon the application and the direction of heat flow. R-value Calculations

Q: If you install two layers of AstroShield will you double the R-Value?

A: No. By placing two layers together, you will still have the same number of reflective foil surfaces. The only way to increase your R-Value is by adding another bubble layer.

Q: Why do I need an air space next to the AstroShield surface?

A: All Low E materials achieve the majority of their thermal insulation performance ONLY when they face an air space. "E" stands for emissivity, the converse of reflectivity. Low E surfaces like AstroShield, when facing an air space, will either reflect 95% of the heat that is directed to them across the air space, or they won't emit more than 5% of the heat that is conducted to them.

Q: Will AstroShield make a person itch as fiberglass insulation does?

A: No. AstroShield insulation is manufactured out of polyethylene film, air bubbles and metalized aluminum on polyester film. There are no irritants or fibers in our foil insulation. AstroShield can be installed without the hassles of protective clothing, masks or gloves.

Q: Do I need special tools to install AstroShield Foil Insulation?

A: No. AstroShield can be cut easily with a razor blade or scissors and installed with common staples, nails or screws.

Q: Do I need to tape the seams?

A: To achieve an absolute moisture barrier, taping the seams is recommended. Seams can be easily taped using our reflective aluminum tapes.

Q: All of the equipment in my metal building is getting damaged from condensation drips. Do you have a product that can help?

A: AstroShield Foil Insulation is perfect for metal building insulation and will reduce, if not stop, your condensation problem because it creates a buffer between interior and exterior temperatures.

Q: I am installing a radiant heat system in my new home. What Foil Insulation products should I use?

A: Staple the Tabbed version of AstroShield II 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. Check with your local building code officials to be sure your application meets code requirements.

* R-Values for AstroShield Reflective Insulation have been calculated for nominal 2 by 4 inch wood-frame wall assemblies described in ASTM STP 116. For complete details regarding methodology, contact your nearest Innovative Energy Sales Office. AstroShield's ability to reflect heat in open applications is not fully measured by this test. It's that extra reflective capability that makes it possible for AstroShield Foil Insulation to keep people and animals comfortable all year long.

WARNING: Reflective bubble-pack insulation will ignite if exposed to fire or sufficient heat and intensity. Protect insulation from exposure to open flame or other ignition sources during shipping, storage and installation.

How to Install Reflective Insulation

  1. AstroShield works best when there is a 3/4" air space on each side of the insulation. (Larger air space is fine but a smaller one reduces its thermal effectiveness.)
  2. AstroShield Reflective Insulation should always be installed on the inside of the structure.
  3. AstroShield will not cure existing problems. Leaking roofs, rot or mold situations or other moisture or structural problems should be corrected before installation.
  4. Any deteriorated wiring should be replaced prior to installing AstroShield.
  5. AstroShield should be at least 3' from any heat producing fixtures, chimneys, blowers, etc. NEVER install AstroShield directly above lighting or other heat producing devices.
  6. Always turn off all electricity in the area when installing AstroShield Foil Insulation.
