WHY UPGRADE TO GLASS BLOCK?
Ultimate Security & Privacy
-
Burglar Deterrent: Thick, masonry-bound glass blocks are virtually impenetrable compared to standard pane windows, protecting your family and valuables.
-
Privacy Control: Choose from highly textured patterns that let in natural light while completely obscuring the view from the outside.
Superior Energy Efficiency
-
Draft Elimination: Our professional mortared seals prevent cold air from seeping into your basement, lowering your winter heating bills.
-
Moisture Resistance: Properly installed glass block prevents water seepage and stands up to heavy rain and snow melt.
Custom Ventilation Options
-
Integrated Hopper Vents: Maintain essential airflow in your basement or garage with secure, built-in hopper vents that feature heavy-duty screens.
-
Dryer Vent Blocks: We seamlessly integrate specialized blocks tailored specifically for your dryer exhaust.
Popular Glass Block Patterns
-
IceScapes (Maximum Privacy): Offers a beautiful, heavily textured pattern that allows light in but provides maximum visual security.
-
Nubio (Classic Look): The traditional, wavy glass block pattern that provides moderate privacy with excellent light transmission.
-
Aktis (Diamond Pattern): Fancy diamond pattern that provides maximum obstruction and diffuses light.
