Garden Box


Garden Box Windows are a combination of windows that help create the perfect solution for an in-home greenhouse. They feature a middle picture window flanked with two casements and a tempered glass roof.


Alpha garden windows will give you a new view on the outdoors. Like all of our windows, this unit has slim lines to bring the outdoors in. This system has ventilating casements on each end to maximize ventilation. Yet the units use compression seals to seal against weather and sound transmission. This unit also incorporates a special PVC seat board that will not rot.


Alpha windows purchased and installed by Alpha come with a lifetime limited warranty. The warranty covers windows to be free of any defects in material and workmanship, excepting broken glass or screening.

  • Vinyl Sash Frame and Vinyl Mainframe combination profiles are warranted against cracking, warping, peeling, flaking, blistering or corroding.
  • Moving Parts of the Basic Window Unit including balances, brass wheels, and locking mechanisms are warranted against defects.
  • Fiber Glass Screening and Screen Frame are warranted against manufacturing defects resulting in rotting or rusting.
  • Insulating Glass Units are warranted against development of material obstruction of vision occurring from manufacturing defects, resulting from film formation or dust collection between interior glass surfaces, caused by failure of the hermetic seal.

In the case of an ownership change, you may transfer this warranty to the new owner at your request.
