What is a common installation method for glass blocks?

The common installation method for glass blocks involves the use of mortar. This technique provides a sturdy and durable bond while ensuring that the glass blocks are securely held in place. Mortar allows for an even distribution of weight and helps in creating a strong structural integrity, essential for maintaining the rows of glass blocks, especially in applications like walls or partitions.

Using mortar also facilitates the incorporation of a grout line, which enhances the aesthetic appearance of the installation. Furthermore, this method accommodates the natural expansion and contraction of the materials over time due to temperature changes.

While adhesive is an option for certain lightweight applications or installations, it is less commonly recommended for structural glass blocks, as it may not offer the same level of support. Constructing a wooden frame is not typically necessary and can complicate the installation process for glass blocks, which are designed to be self-supporting when properly installed in mortar. Sealing with a silicone compound is often used as a finish or for joint sealing, but it does not replace the requirement for a sturdy initial setting with mortar.
