Good morning Ali,

I believe that you do need to re-define the frame dimension and property in eQUEST. You can do this either in the Wizard mode (easier, but limited U-values to select from) or in the "Window Properties" screen in the detailed edit mode.

In the Wizard mode I typically will try a couple of the "named" frame types (AL, wood/vinyl, etc) to find one that has the conductance value that matches my frame. The way to check is: select a frame type, click Finish and go to the "Window Properties" screen and see if it matches your WINDOW output. If I can't find a good fit you'll need to manually enter the conductance values in the Detailed Edit mode.

The answer to your second question: The best way to check is comparing the Window Properties screen (below) with the WINDOW6 screen that gives information on your whole window (glass+frame).

Keep in mind that the window frame dimension is labeled PFD (Projected Frame Dimension) and is given in inches, while the frame width in eQUEST's "Window Properties" screen is in feet.

My last comment is that I recall having some trouble running parametric runs between windows with varying frame thicknesses. As I recall, changing the frame thickness would change the total window area (my goal was to change the frame thickness, while keeping the total window area constant). This may have been an eQUEST 3-63 problem though.

A final check can be done once the file is simulated - I would also suggest that you look carefully through the LV-H reports (there are two relevant sections) and the last page of the LV-D report as this can be used to confirm that what you simulated matches your expectations.

Hope this helps,
Alex
