Think Glass Block for Privacy, Safety and Security

Quality Glass Block

A neighbor’s five-year-old son, learning to ride his bicycle on the back patio lost control and plowed into the basement window.  The boy and his bike were lucky, they survived; the basement window did not.  The shattered glass was both difficult and dangerous to clean up.

A burglary ring was operating in a local neighborhood. The police said they were targeting basement windows. Windows at the foundation level are often tucked behind bushes and concealed in ground level shadows. This gives burglars the cover needed to slip in while unsuspecting residents sleep in the bedrooms above. 

Installation of Glass Block WindowGlass block windows may be the answer to many safety and security issues.  Combining the strength of masonry with the properties of glass gives homeowners the best of both worlds.  Glass block allow light in while keeping almost everything else out.  Residential grade glass blocks may not be impregnable, but they do not fracture and are far sturdier than their regular glass cousins. Most burglars will move to another house instead of trying to break into solid glass block and Johnny’s bicycle will bounce off the window and not crash through it. In fact, Solid glass block windows, joined with beds of mortar in a foundation wall, are almost as strong as the foundation itself.

Each block has glass surfaces around a core of insulating airspace, which are also much more energy-efficient than regular windows. Whether you want windows that are almost as clear as a regular window, textured or even with an opaque finish that lets light in while providing complete privacy, there is glass block design that will fit your needs.  Glass block windows do not split, warp or rot, and never need painting.
