NRCA responds to MRCA'S position on aged R-values

Abstract
The MRCA published a position paper on 11/1/85 that recommended the establishment of an interim in-service resistance R-value for urethane and isocyanurate roofing insulations. As could be expected, MRCAs action has sparked a fair amount of controversy between various segments of the industry. Some manufacturers and their respective associations have cried "foul." Others have written to MRCA to challenge the associations data, claiming the numbers are inaccurate and unreliable. Still others have simply said, "Who cares, we all know that insulation values have been subjected to more manipulation than the federal budget." MRCA approached NRCAs Executive Committee and Board of Directors to seek assistance in resolving this issue. The Assn. concluded that it is concerned about the issues raised in the MRCA position paper and would like to assist in bringing the matter to a prompt & effective resolution for the benefit of the industry. To that end, NRCA has communicated its concerns to the RIC/TIMA and requested that, if possible, prompt industry-wide action be taken to begin resolution of this issue. NRCA does not have independent testing data on this issue, so it is simply unable to take a position regarding the need for an interim in-service R-value, let alone what that value might be if adopted. In an attempt to adivse our readers of this important undertaking by MRCA and its position, we printed the position paper in total.
