Description

This report outlines research conducted on several non-residential door products, to assess their air-leakage characteristics and thermal transmittance (U-factors) at representative sizes.

Specimen types and sizes were chosen to be representative of their product type, based on a market survey conducted as part of this project.

The products were tested to measure their air leakage at various pressure differentials, and to measure their thermal transmittance (U-factor) in the absence of air leakage. Computer simulation was used to determine total-product U-factors under standardized conditions.

Several recommendations are made to modify the NFRC test and simulation procedures, to address specific considerations related to the products evaluated in this research project. Specific language appropriate to the relevant NFRC Standards is included in this report.
