It must include the frame. Which portions of your glazing I I assembly will be insulated vs. not? Please look closely at the options for compliance below. I'm guessing your options will be limited to number 4 and perhaps 5. Marketing brochures are not sufficient for this. The following are acceptable methods under the 2015 IECC to verify fenestration U-factors as part of the building thermal envelope: 1.NFRC certification; label applied to window assembly and verified at field inspection. 2.Default values from 2015 IECC tables C303.1.3(1)C303.1.3(2), R303.1.3(1), and R303.1.3(2). 3.Default values from Table 4 U-Factors for Various Fenestration Products in 2013 ASHRAE Fundamentals Handbook chapter 15, pg. 15.3. To document the chain of custody, a certificate, affidavit or other evidence from the manufacturer confirming compliance with the above method is required. 4.Calculation methods in 2013 ASHRAE Fundamentals Handbook chapter 15, pg. 15.3: "U-Factor(Overall Coefficient of Heat Transfer)".A calculation is required for the standard NFRC window size of 47.2"x 47.2".To document the chain of custody, a certificate, affidavit or other evidence from the manufacturer confirming compliance with the above calculation is required. 5.U-ratings by an NFRC—accredited lab in accordance with NFRC-100.
