Take a look at this article: https://ieeexplore.ieee.org/document/8740123 W. Conniott, J. Vieira, S. Monteiro and R. F. S. Caldeirinha, "Low Cost Radio Shielding Effectiveness using Carbonised Wood," 2019 13th European Conference on Antennas and Propagation (EuCAP), Krakow, Poland, 2019, pp. 1-4.
It has a number of good graphs of attenuation and a table for attenuation of signals at 2.4Ghz and 5Ghz wifi The closest example that have is two 9cm CLT with a 10cm gap between them (~=180mm) -- the SE was 16.05dB (2.4Ghz wifi) and 22.63dB (5GHz Wifi) The composition of the floor tiles might be significant, e.g. if they're anti-static as that might look more like the carbonized wood example.

We have a new building currently going up that uses CLT (Cross Laminated Timber) for its floors. It will just be 220mm or 300mm CLT and raised floor tiles, no concrete or any other layers. Anyone of experience of wifi attenuation/losses through these materials? Regards, Jen. Jennifer Wilson Senior IT Networks Analyst University of Central Lancashire [Image removed by sender.
