Title: Requirements for glass as a dance floor
Post by: Hagenbeck on June 05, 2017, 07:15:30 PM

Hello,

I'm trying to make a glass dance floor, of about 3200 x 2200mm. I have bought six 540 x 540 mm pieces of temperated + temperated laminated glass, for a total thickness of 20mm (10 + 10). The glasses are supported by a mettalic structure, simply by resting its borders on it (around 10mm of each border).

I would like to ask you guys if you think this setup is safe. Here are my concerns:
- I will be putting some led lights on the floor, below the glasses. I would like to put some coating/film on the bottom so that the lights can't be seen from above, and thus having a more uniform, diffuse light. Do you have any tips on which coating specs should I use?
- There will be a max of 4 people on it at the same time. Can these specs handle this weight, with jumping and dancing?
- Also, I'm worried about dilatation issues. Is there a problem if I leave no space between the glass pieces? Will it crack through dilatation like other materials (they will be always on the same indoor spot, stable temperature all year long)?
- Will chamfering the glass help in correcting minor height differences?

I attached a sample image from the internet that gives a good idea of the final result (lacking only the lights).

Thanks a ton!

I'm afraid I cannot help with your safety specifications, but please, ban stiletto heels.

Welcome to the gmb! :)

Check with some of the glass companies and engineers that have fabricated glass walking bridges, and balconies that extend from high rise buildings. I know of a glass bridge in Chattanooga, TN that has been there for well over 10 years and crosses over a major interstate highway. I even walk occasionally on a glass floor with water running under it at a local Chinese restaurant\. Get some good engineering help to insure your liability issues.

This shouldn't be a problem. Contact Pilkingtons in St Helens: http://www.pilkington.com/en-gb/uk/contacts
