Can glass walls be load bearing?
When considering the question – can a glass block wall be load bearing – the answer is a resounding “no.” While it may take some time, eventually, the blocks will start to crack and completely break. This can result in serious and expensive property damage and even create a huge safety hazard.
Why do glass blocks crack?
What causes this need for expansion is temperature change (getting warmer), causing the glass bricks to grow and or the surrounding structure expanding in on the glass bricks and crushing them. There is another cause for expansion that is far less obvious and really tragic because it could have been avoided altogether.
Are glass blocks outdated?
While beauty is in the eye of the beholder, many current design experts, home decorators and architects agree that the look of glass block is outdated, unattractive and unnecessary.

What is tempered glass?
Tempered glass is also known as Toughened glass. The tempering process involves first cutting annealed glass to the desired size and shape, edging the glass as indicated, then heating the annealed glass back up to near 650⁰C (1200⁰F) and then very rapidly cooling it. This high speed of cooling causes stress in the glass and forms a compressive laver on the glass surfaces and a tension layer in the core. The delineation of zones in the tempered glass is similar to heat-strengthening but the compressive strength of the surface is significantly higher. The tempering process increases the mechanical and thermal strength of annealed glass, making it historically four times as strong as annealed glass. Tempered glass may to have glass roller wave distortion and bow caused by the strengthening process. Upon breaking, the pattern is unique in that it forms small cube-like pieces which may or may not fall out at the time of impact but have virtually no residual strength as a glass unit when faced with subsequent load. Tempered glass can be fabricated with the same value add coatings and lamination as annealed and heat-strengthened glass. Tempered glass is typically used in areas that
How is annealed glass strengthened?
Chemically Strengthened Glass is annealed glass which is strengthened by a chemical exchange of ions. The chemically strengthening process involves first cutting annealed glass to the desired size and shape, edging the glass as indicated, then submerging the glass in a solution that promotes the ion exchange where the smaller ions are replaced by larger ions. This exchange causes a compressive layer on the glass surfaces and a tension layer in the core. The strengthening process increases the mechanical and thermal strength of the glass, however there is no common value used in the industry to account for the strength enhancement. Chemically strengthened glass tends to have levels of glass distortion and bow similar to the annealed base glass. Upon breaking, the pattern is similar to annealed glass, but in some cases the break pattern can be adjusted to be smaller. Cutting after strengthening (with traditional methods) may weaken the glass. Fabrication of chemically strengthened glass is beginning to be more common in the industry. Lamination of chemically strengthened glass is possible, however compatibility studies should be undertaken prior to use. Chemically-strengthened glass is typically used in areas that
Why is annealed glass stronger than annealed glass?
The heat strengthening process increases the mechanical and thermal strength of annealed glass, making it historically twice as strong as annealed glass. Heat-strengthened glass tends to have low levels of glass distortion and bow caused by the strengthening process. Upon breaking, the pattern is similar to annealed glass.
