Double Hung


Double Hung Windows feature two mobile sashes that can move up or down and tilt in for easy-cleaning. The easy-cleaning feature lets you clean the exterior side of the glass which will keep your windows looking new even twenty years later.


Alpha double hung windows are traditionally designed around the aesthetic style of Early American architecture. All sashes tilt in for easy cleaning. Units are fully weather-stripped with high-tech seals to assure resistance against the elements.

This photo features a mulled double hung unit that utilizes a single frame. Alpha exclusively manufactures the single frame mulled unit so that units do not require a mullion strip to be glued between the windows. This feature maintains your home's weather-tight seal while maintaining your home's integrity and security.
