U-factor chart. Many of the heat transfer processes encountered in industry involve composite systems and even involve a combination of both conduction and convectionWith these composite systems it is often convenient to work with an overall heat transfer coefficient known as a U-factorThe U-factor is defined by an expression. Any glazing area in exterior doors should be included with the appropriate glass type and analyzed as a window. What influences the U-factor.

Where assembly U-factors C-factors and F-factors are established in ANSIASHRAEIESNA 901 Appendix A such opaque assemblies shall be a compliance alternative where those values meet the criteria of this table and provided that the construction excluding the cladding system on walls complies with the appropriate construction details from ANSIASHRAEISNEA 901. High performing double window pane set-ups will have a U-factor of 030 or.

Ideally Florida homeowners should aim to have a U-factor under 030 paired with a solar heat gain coefficient SHGC. Products lacking such a labeled U-factor shall be assigned a default U-factor from Table R303131 or R303132. In the North-Central Zone the U-factor requirement is 030 or less and the SHGC must be 040 or less.

The South-Central Zone allows U-factors of 030 or below and SHGC ratings of 025 or below. 2-hr-F thermal break Frame U-Factor includes heat transfer through surfaces perpendicular. Your windows U-Factor refers to the measure of heat gain or loss through the glass.
