Reflective Insulation Manufacturers Association

Representing the Reflective Insulation, Radiant Barrier and Interior Radiation Control Coating (IRCC) Industries

Who We Are

RIMA-I is a non-profit industry association that provides reliable research, information and resources on the use and benefits of reflective insulation, radiant barriers and interior radiation control coatings (IRCCs).


Building Codes

RIMA International began in 1978 with a small group of reflective manufacturing companies coming together to get reflectives into the building codes. The codes have changed dramatically over the years, and the importance of our presence within the codes is stronger than ever. As the voice of the reflective insulation, radiant barrier and IRCC industries, it is critical and priority one for RIMA-I to be active within the codes working both offensively and defensively on behalf of the industry. RIMA-I has established the Advanced Building Code Coalition (ABCC) to build support and to work together within the codes.  If you would like to learn more about this effort and how ABCC can protect you, email us for more information.

Verification Program

Verification Program

This program verifies the test data and marketing claims of a reflective product to ensure the product meets with current ASTM codes and standards and should perform as claimed.  All verified products have gone through a detailed review by a third-party accredited laboratory.  Product verification is renewed annually with random testing conducted annually as well.

RIMA International has joined with ASTM International and their certification team at SEI to oversee and institute this program.  It was a logical partnership considering the program’s intent is to verify reflective products meet all required ASTM standards and codes.   You can read more about the program and see a list of current verified products.

Reflective Insulation distribution, radiant barriers and IRCCs interior radiation control coatings testimonialsToday, most of electric bills are the minimum bill of around $20/month due to the reflective insulation and the solar panels working together. If I am given the chance, I would strongly urge anyone to install reflective insulation in the attic and also in the sidewalls of the home. This should become standard in any new home construction. – Sent in by David in Avon, IN Continue reading…
