What Kind of Glass Is Used in Glass Flooring?

In general, expect glass flooring panels to be 1 ¼” thick.

However, your glass manufacturer and engineer will create laminated glass flooring panels specific to your project. These will be both appropriately thick for your design and fully in compliance with international building codes and ASTM glass flooring standards.

The necessary thickness of a glass floor will vary based on several factors:

• How much weight is expected on that flooring
• The span of individual glass panels
• The engineering of the support system around the glass

For exterior glass floors, weight considerations include:

• The maximum number of people expected at any given time on the flooring
• Snowfall
• Outdoor furniture
• Grills, rain barrels, or other objects in that outdoor space

2. Glass Floors and Safety Design

Your laminated glass flooring panels should be engineered with failure redundancy built into the design.

With glass flooring, safety should always be your number one concern. While breakage of any glass floor is highly unlikely, proper failure redundancy is still necessary.

Given that, every glass flooring panel should be designed in a three-ply system. This essentially means every single panel is actually three pieces of glass together.

This system is a safeguard against failure. If any individual piece of glass does crack, shatter, or otherwise fail, the floor will still be intact. The remaining two pieces of glass can safely bear the structural load.

3. Glass Floors and Aesthetic Design

When choosing the kind of glass to use in your glass flooring, safety always comes first. Once those considerations are taken care of, then you can move to aesthetic choices.

Because of the customizable nature of glass, you have many design options.

This includes:

• The type and appearance of anti-slip surface
• The level of desired transparency (from clear to frosted)
• The color of the glass panels
• Textures or patterns incorporated into the flooring
• The size, shape, and thickness of the individual panels

4. Insulated Glass Flooring Panels

If heat loss or retention is of any importance in your project, talk to your glass manufacturer and engineer about insulated glass panels.

These energy-efficient insulated panels offer great functionality, increase the comfort of the living space below, help you save on heating and cooling costs, and are an overall more eco-friendly product.

Insulated glass panels can also keep the space below at a more constant temperature. If the space is a wine cellar, for example, that can help preserve the integrity of the product below the flooring.

5. Waterproof Glass Floor Panels

If the space directly below the glass flooring is livable space, talk to your manufacturer and engineer about creating a fully waterproof floor. This is especially relevant for outdoor glass flooring, which will be subject to rain, snow, sleet, and other moisture.

If your flooring is simply water resistant, that livable space underneath could eventually sustain water damage.
