WHY CHOOSE GLASS BLOCK WINDOWS
Advanced Security
-
Burglar Deterrent
Our windows are built to stop intruders from prying open your vulnerable basement window frames completely.
-
Lasting Privacy
By offering various, obscure glass patterns, we provide a clean, modern aesthetic that allows abundant natural light while fully blocking any view from the outside.
Stop Drafts & Prevent Leaks in Your Basement
-
Thermal Insulation
Heavy-duty glass-block locks in your indoor climate, ensuring your basement remains warm throughout freezing Illinois winter weather conditions.
-
Eliminate Leaks
We remove rotting wooden sills and seal every edge tightly, permanently stopping cold air & water from entering.
Vented Glass Block Basement Windows
-
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 premium mortar lines wipe clean effortlessly, completely eliminating the constant struggle against stubborn bathroom mildew growth.
