The process to design a curved glass block wall is not rocket science! Yes – you heard that right. Many people want the benefits of a curved glass block wall (which can be less costly and sturdier than custom curved and bent flat glass) but they are unfamiliar with the design, fabrication and installation approaches required to create a curved glass block wall.

In the article you’ll learn where to use this type of wall, how the product, fabrication and installation approaches in “tight curves” vary from “sweeping curves,” and also identify unique ways to personalize your wall.

Where to use a curved glass block wall
- Showers – The number one use of a curved glass block wall is for shower enclosures. What makes glass blocks particularly appealing in showers is there are curved blocks (the shapes are named “radial” and “arque”) which allow for a tight 12” inside radius. This allows for projects as small as tub to shower conversions which can create door-less glass block walk in showers.

- Conference rooms – Glass blocks have been a favorite for corporate offices to create privacy (by using obscure type patterns) but also let natural light to stream into a space. For additional style “sweeping” curved walls (sweeping curved walls are those which have slight curvature and a large inside radius) are popular.

- Partition walls in homes, lofts and businesses – Wherever it’s desired to create a separation between rooms but simultaneously have the ability to allow light transmission glass blocks are a sound option. These walls can be curved or straight in their design.

How products, fabrication and installation approaches vary with “tight curves” vs. “sweeping curves”
- Tight curves – A wall with a tight curve (i.e. a wall with a 38” radius or less) can be made using glass block shapes (called “radial” and “arque” blocks) where the blocks are pre-shaped (the curvature is actually manufactured into the block). Each block creates a 22 ½ degree radius (combining 4 of these blocks makes a full 90 degree turn).

- Sweeping curves – Sweeping curves can be defined as those where the inside radius is larger than 38”. These curves usually have to be made with “standard” non-shaped glass blocks of either a square or rectangular design. To make the curvature work the mortar of the hand laid glass blocks must be varied on the inside vs. the outside (for example a 65” radius can be created using 8” x 8” blocks where the joint on the inside will be 1/8” and the joint on the outside will be 5/8”). These types of projects have the drawback that they require a skilled glass block or mason contractor to install.

Unique ways to personalize your wall
There is no need to have a boring clear glass block wall anymore. Consider some of the following options:

-Colored & frosted glass blocks
-Etched or colored glass block murals
-Glass tile blocks
