Every component of our Builder Series real glass block window line was developed by Pacific Glass Block to provide a lifetime of maintenance free service and beauty.

 Real glass blocks will not scratch or haze like acrylic blocks when you wash them, and there are no cleaning restrictions for real glass blocks.  Just clean with the same cleaner you use on the other surfaces in your bath or shower. And in every window we make, we use specially formulated translucent sealants that have an anti-fungal agent blended in to help prevent mold and mildew in wet areas.

 Our heavy duty Builder Series vinyl frames are profiled to shed water away from the glass on both sides, so the water won’t pool, and the glass and frame components will dry quickly after use so materials will not degrade from moisture over time.

Privacy Comparison Between Block Patterns

This frame profile presents a much more pleasing look than others acrylic block or privacy window products. There are no large flat surfaces to take away from the beauty of the glass blocks, and the window frames look more like other regular window frames.

Builder Series glass block windows can add individuality and style to bathroom and shower spaces while providing a wonderful natural light source that also provides privacy, or you can use them to add originality and brighten up kitchens or bedrooms. You can also enrich the personality of stately entrances with easy-to-install glass block side lite windows. Interior or exterior, residential or commercial, wet areas or dry, our Builder Series real glass block windows can make your project exceptional.
