A number of proposed changes to both the NFRC 100A and the NFRC 200A resulted in considerable discussion during this afternoon’s Technical Committee block.
After lengthy discussion on the NFRC 100A ballot, "Procedure for Determining Fenestration Attachment Product U-factors," the Attachment Subcommittee sent the ballot back to task group with nearly a dozen persuasive and substantive negatives to address.
The Attachment Subcommittee then turned its attention to the NFRC 200A ballot, "Procedure for Determining Fenestration Attachment Product Solar Heat Gain Coefficient and Visible Transmittance at Normal Incidence." After reviewing the ballot comments, the subcommittee sent it back to task group.
