Glass Block Windows in Chicago
Glass block is a Chicago basement classic: it lets light in, keeps prying eyes and break-ins out, and seals better than old single-pane basement windows.
Why Homeowners Choose Glass Block
- Security for basements and gangway-facing windows
- Privacy for bathrooms while still letting light in
- Energy efficiency compared to old steel or wood basement windows
- Low maintenance: nothing to rot or rust
Options
- Vents (small operable inserts) for basement airflow and dryer exhaust
- Different patterns from clear-ish to frosted, for more or less privacy
- Mortared or pre-assembled panels sized to the existing opening
Before You Replace: Egress
Bedrooms and some finished basement rooms need an egress-size window (an opening large enough to climb out of). Glass block doesn't meet egress requirements, so those rooms need a different window.
Frequently Asked Questions
Can glass block go in my existing window opening?
Usually. Panels are built to fit the opening, and the surrounding masonry is repaired as needed.
Do glass block windows need a vent?
Not always, but basements and bathrooms benefit from one. Some homes need a vent for the dryer exhaust.
