Trying to override a window construction with a historic single pane window with U-factor 1.64 (IP). While previewing the construction, the U-factor seems to be off by a certain factor. The display preview should be showing the U-factor as 9.31 (SI) as opposed to 5.244. When I deconstruct the HB Subface subset, the u_fac_si shows 5.244. But when I deconstruct the construction set after applying the subface_set, the u-factor is correct. The issue persists when I try other values for double/triple pane as well but the factors by which they are off is lower. For example, when I input 0.38 (IP) as u-factor, the preview display shows 3.438 (SI) as opposed to 2.1577 (SI).
The HB preview also shows the U-factor as 5.244 as opposed to 9.31
However, the same setup works with the HB default construction set. Is there something I’m missing or incorrectly assigning? Appreciate any help here. Thanks!
