Dimension Calculations
Elevation charts provide wood unit dimensions for units with the standard 1-15/16" brickmould. Below are the calculations to determine the frame size of units with brickmould.
NOTE: All measurements are nominal. Elevation charts are not to scale. Divided lites are optional. Some installation procedures will require a larger rough opening than noted (i.e. installations utilizing our installation clips), therefore, you may need to increase the rough opening size accordingly. Rough opening gaps may be increased up to a maximum of 1/2” on all sides and still be within good practice guidelines. The side jambs of double hung units extend above the head jamb; additional space for the rough opening height may be necessary. For rough opening recommendations, see pg. 194.
