WHY CHOOSE GLASS BLOCK WINDOWS
Vented Glass Block Basement Windows
Advanced Security
-
Burglar Deterrent
Solid mortared glass block has no sash or frame to pry, which makes basement entry far harder than with a standard window.
-
Lasting Privacy
Obscure glass patterns let in abundant natural light while keeping the view from outside blocked.
Stop Drafts & Prevent Leaks in Your Basement
-
Thermal Insulation
Heavy-duty glass block seals out the drafts that make a basement cold through an Illinois winter.
-
Sealed Edges
We remove rotting wooden sills and seal every edge tightly to keep cold air and water out.
-
Seamless Dryer Vents
We embed a custom dryer vent block directly into the mortar, so your exhaust vents safely outside with no gap in the seal.
-
Fresh Air Hopper Windows
A secure, latching hopper vent built into the panel gives you natural cross-ventilation whenever you want it.
Beyond the Basement: Custom Shower Walls
-
Luxury Spa Aesthetics
Turn a master bathroom into a spa-like retreat with light-diffusing glass block walls and dividers.
-
Mold-Resistant Maintenance
Smooth glass surfaces and clean mortar lines wipe down easily, with far less mildew buildup than tile grout.
-
Custom Walk-In Designs
We build doorless shower enclosures configured to fit your bathroom layout, with easy step-in access and no loss of privacy.
