14 Aug 2018 We have glazed windows and need to improve the overall U factor from .338 to . 35. Is there an aftermarket film that will increase U factors?


The U-factor or U-value is the overall heat transfer coefficient that describes how well a building element conducts heat or the rate of transfer of heat (in watts) through one square metre of a structure divided by the difference in temperature across the structure.

U-factor is a factor in a well-known equation involving multiplication. The heat loss equation shown here states that Q — the rate of heat flow through a building assembly (in Btu/h) — is equal to the area of the assembly (in ft²) times the ΔT (in F°) times the U-factor (in Btu/ft² • hr • F°). These C -, F - and U -factors are based on assemblies that are not required to contain insulation. Evidence of compliance with the F -factors indicated in the table for heated slabs shall be demonstrated by the application of the unheated slab F -factors and R-values derived from ASHRAE 90.1 Appendix A. 2011-05-30 · R-value measures resistance to heat flow; U-factor is the mathematical inverse (1 divided by R-value gives you U-factor), and measures the rate of that heat flow. In a cold climate a good U-factor for a window is between 0.17 and 0.39.

This is why the U factor is very important when identifying the heat and cooling requirements or areas within a structure. The entire assembly is identified and tested, prior to being given a U value. Unlike the U-Factor, you want a higher R-Value, as it indicates better insulation.
