Sizes

There are multiple sizes of glass blocks available – they are typically sold in standard installation sizes such as  4″ x 8″, 6″ x 8″, 8″ x 8″ (the most common size) and 12″ x 12″. There are also curved blocks which help build curved walls – for example you can order blocks with a 22.5° soft radius so 4 of them gives you a 90° angle.

All of these are available either 3 or 4 inch thicknesses. Most of the country uses 3 inch thick blocks, but Florida, Texas and many other coastal areas require 4 inch block for all exterior applications

Keep in mind that these dimensions are actually 1/4″ bigger than the actual glass blocks you ” x 7¾”.will receive because the spacers add 1/4″. So an 8″ x 8″ block is actually 7¾” x 7¾”.

Types

  • Colored – In addition to white, glass blocks are available in dozens of colors, allowing you the utmost creativity in designing beautiful interior or exterior spaces
  • Metalized Edged – Metalized bands makes glass blocks more reflective when the light hits them. This is often used for a more  contemporary look such as the new Art Deco style commonly seen in Miami.
  • 3D – Instead of a a flat face on the front, these blocks will have wings or flutes to make trapezoidal or other shapes which can extend 2 or 3 inches. This style is not particularly common in the United States but is very popular in Europe.
  • Etched – These glass blocks are part of a custom installation where you can get your own design or mural laser etched onto the block.  Our subcontractors create a template from your image, assemble the wall, and add a 1/8″ deep etching, then we ship you the blocks with them all numbered like a puzzle so your installer can install the etched wall.

Specialty Glass Block

Most glass blocks are hollow, and the standard wall thickness is 1/4″, however there are special installations for hurricane rating, impact ratings, extended fire ratings, and even tornado, bombproof and bullet-proof ratings. These blocks may have 1/2″ or 3/4″ walls, or even be solid. To learn more about the different types of special installations, please visit our glass block installation page.
