Why Choose Glass Block Windows
ADVANCED SECURITY
-
Burglar Deterrent
A mortared glass block panel 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 & SEAL THE OPENING
-
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 the perimeter to keep cold air and water from working through the opening.
Your Glass Block Options
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.
-
Easy to Clean
Smooth glass and clean mortar lines wipe down easily.
-
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.
