Glass Block Benefits & Applications

Beauty and Versatility: Extraordinarily versatile and available in many aesthetically pleasing sizes and styles, 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: Glass block provides exceptional visibility in compliance with ADA guidelines for enclosed areas and has a dynamic relationship with light, both natural and artificial. As light changes, so does the appearance of the material and its surrounding environment. It is also scratchresistant and transmits up to 80% of available light in both directions without any yellowing, clouding or weathering.

Security: The SEVES High Performance Line of glass block products is comprised of products that offer the highest value, performance features and benefits related to improved safety, energy efficiency, aesthetics and decorative choices.

Energy Conservation: Glass block can provide more than two times 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 are also significant. Contributing to this is the louvering effect of glass block’s horizontal mortar joints, which helps reduce light transmission from the higher summer sun. The size and orientation of the block can greatly affect the amount of shading that can occur.

Graffiti Resistant: Glass block resists damage and is easy to clean.

Noise Resistant: Three inches of solid glass makes VISTABRIK® a dense barrier to sounds from trains, traffic, crowds, sirens, and machinery with a 53 STC level. THICKSET® Series Block STC ranges between 48-50, and a Premiere Series Glass Block 35 to 40.

Sustainable Design: Glass block, made largely from sand and limestone, is 100 percent recyclable, inert and low maintenance. Additionally, glass block is highly durable, lasting 50 years or more. Its dynamic relationship with light gives architects the opportunity to create both aesthetically pleasing and energy efficient spaces.
