I'm going to build a ROR obs for a dob and I'm weighing up whether to build the floor with concrete or timber bearers.

I built a house with a waffle pod slab and it's very easy to do the same with the obs, but I'm very wary of the thermal heat that's stored in the concrete. I'm worried it will mess up the seeing for an extended period while it slowly cools to ambient.

With the timber floor I see no such issues with thermal management.

I'm sure I'll find a heap of useful information once I start trawling through all the threads here, but for now, what is the consensus around the best material to construct the floor with.
