Glass Block for Walk-Out and Sloped-Lot Basements
Frankfort's sloped-lot subdivisions put basement windows at grade or below, where runoff collects and frames rot from the outside in.
-
Where the Grade Works Against You
On a sloped lot, water moves toward the low side of the house. Masonry handles that; a framed window eventually doesn't.
-
Fitted to Non-Standard Openings
Walk-out and daylight basements rarely use stock window sizes. Every panel is built to the measured opening.
-
Venting a Below-Grade Room
A built-in hopper vent moves air through a basement that has no other opening.
Questions about cost or installation?
Why Basement Windows Fail
Basement openings punish ordinary windows. Moisture, ground contact, and no easy access for repairs.
-
Nothing to Rot or Seize
No sash, no track, no balance. The failure points a basement window has are the ones glass block doesn't.
-
The Opening Nobody Watches
Basement windows sit out of sight behind shrubs and window wells. A mortared panel takes the easiest way in out of play.
-
Daylight Without a View In
Frosted block brings usable light into a room that mostly gets none.
