A/C Trays

Designed as a low maintenance option for building owners to have individual air conditioning units supported in various window configurations. Aluminum trays with drainage channels are attached to an insulated panel that can be easily interchanged with a glass sealed unit.

Design Tip

Casements can be excellent alternatives to single hungs in traditional homes with the use of Simulated Divided Lites (SDLs). The heritage style is maintained with historical divisions in the glass, while the energy performance is significantly improved with the compression seal.
