Revision history [back]

When I loaded a component "Concrete Block - 8 in. - 105 lb/ft3 - Solid Grouted" from the BCL online, and then run the model, I can see that the U factor with film is 3.15 W/m2K, which is 0.5547 Btu/ft2hR. But per the TEK note 06-02C1 from NCMA, it should be 0.527 Btu/ft2hR. What makes the difference?

Thanks!
