When planning a remodel or new construction project, the question is often asked about the difference between Glass Pane windows when compared to Glass Block windows. As stated in the Do It Yourself article discussing basement windows, “Glass block basement windows not only discourage burglars from entering your house but also enhance the aesthetic appeal of your basement. Glass block windows are also famous for their good insulation capabilities.”
These are some additional comparisons followed by a chart for easy viewing.
BEAUTY AND VERSATILITY
Glass Block offers virtually limitless design possibilities. Glass block walls, partitions and windows combine the delicate beauty and light transmission of glass with the strength of glass block.
VISIBILITY/LIGHT TRANSMISSION
Crystal clear Glass Block provides exceptional visibility in compliance with ADA guidelines for enclosed areas. It is also scratch-resistant and transmits up to 80% of available light in both directions without any yellowing, clouding or weathering.
SECURITY
When added security is needed in their projects — architects, designers and home builders have chosen Glass Block which offers enhanced resistance to impact, fire, sound transmission and weather.
ENERGY CONSERVATION
Glass Block can provide more than double the thermal resistance (R-Value) of single-glaze 1/8″ thick plate glass. The differences between the shading coefficient of glass block and flat sheet glass is also significant.
