Sizing Considerations
Sizing Considerations
Several factors affect the size of FoldUp™ windows, including sash size, sash weight*, balance limitations**, limiting geometries, installation conditions, and ergonomic factors. Because the window sashes uniquely fold up and out of the living space, unit size B and header height A are critical. FoldUp™ windows typically sit on a knee wall (or fixed window) so that height D needs to be considered as well depending on how you plan to use your interior space. It is recommended that unless used over a table or counter that the distance from the sash to the floor C*** ends up between 80”-84”. At this height the sash are well above the user’s head, but also still easy enough to be reached for opening and closing.
*Glass is the largest factor affecting weight
**FoldUp™ windows employ hidden balances
***Note that the lower sash angle may vary based on size and style of window
MOUNTING HEIGHT CHARTS
CORNER CONFLICTS
When using FoldUp+In™ windows on an inside corner, there can be a conflict where the sash will obstruct one another with both windows open at once. In these instances there are several potential solutions:
- Use FoldUps™ at both locations and only open
one at a time - Use a matching double hung on one of the corner
windows - Build out the corner wall(s) enough to eliminate
the issue - Use a properly sized door at the corner, assuming
the door can open beneath the elevated FoldUp™ window - Design so that FoldUp™ windows on one wall can be mounted higher than ones on the adjacent wall
For specific window design dimensions consult your FoldUp™ representative.
