Aluminum vs Vinyl Window Frames for Maryland Climate

Why Maryland Homes Put Window Frames To The Test
From humid summers to cold snaps and wind-driven rain, Maryland weather asks a lot of a window frame.

It affects drafts, condensation, maintenance, and how long the whole unit stays square and sealed.
