FoldUp Windows: Bring the Outdoors In

A Unique Window that Creates New Opportunities

Used for screen or sun rooms, pass-thru windows, porches, pool houses, dining areas, storefronts, the window folds upward to an opening almost twice as large as a traditional double hung. However when closed, Heartwood FoldUp has the look, feel, finish, and performance of other traditional wood windows.


Traditional or contemporary window styling, FoldUp’s are customizable to your specific needs:

  • They can often help expand the use of landmark properties while satisfying the requirements of historic commission.

  • Create excitement, comfort and curbside appeal for restaurants and retail businesses.

  • Create convenient, obstruction free pass-through windows for your kitchen, bar, or pool house.
