Glass Block for Fire Protection
Superior fire resistant glass blocks are manufactured through a simple, yet exacting process. The process is designed to maintain the highest quality standards on the market. The standard materials in a typical unit of glass block offer transparency, which allows the block to emit generous amounts of natural or borrowed light. At the same time, each glass block provides varying levels of energy efficiency, sound control, security, and visual texture. Lastly, glass block provides a unique combination of privacy and light transmission to make any home more appealing.
An extremely important feature of thickset 90 Glass Block, critical to safe building design, is the products inherent fire-resistance properties. By varying the face thickness of the product, as well as conforming to installation specifications, fire rated glass block is able to offer products approved and rated according to Underwriters Laboratory (U.L.®) Standards.
