AstroShield Reflective Insulation

Astro Shield Logo

Improve Interior Comfort

AstroShield, an improved version of the product previously known as Astro Foil insulation, is an easy-to-install line of reflective insulation used for a variety of construction applications. AstroShield, an environmentally safe and non-toxic product, features a Polyethylene bubble sandwiched between two protective sheets, one or both of which are composed of a strong metalized polyester film.

This combination provides an insulating surface that uses reflective technology to block up to 95% of radiant heat. Installing AstroShield properly can dramatically increase the thermal performance and energy efficiency of your space. Astroshield aims to keep energy costs lower and interior spaces more comfortable. See our product line listed below.

Why choose reflective?

Traditional insulation methods do not reflect radiant heat away. AstroShield, like a radiant barrier, is a highly effective blockade to the transfer of radiant heat.

AstroShield reflective insulation is easy to use and safe for the health of your installers.

Mass insulations like fiberglass, cellulose and foam merely slow down the transfer of conductive heat by absorbing it. The middle bubble layers of AstroShield work in a similar way to provide a thermal barrier against conductive heat transfer, while also providing added strength to the material’s structure.

* 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.

The manufacturer believes this information and recommendations herein to be accurate and reliable.

    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.
