I have finally finished my dwelling to the point that I am ready to plan the installation of the radiant ceiling panels and am having a lot of trouble visualizing the work sequence.
I will be utilizing the panel construction shown in Siegenthaler's Modern Hydronic Heating handbook per attached.
But how can you sequence the layers?
The floor truss bays will be insulated with 3-1/2" of mineral wool insulation. Then OSB will be attached to the bottom of the trusses. Then 3/4" rigid foam strips will be glued in place between Thermofin U transfer plates.
Here's the issue, this all needs to be done prior to starting the installation of the pex tubing, but by this point it is too late to run the pex leaders from the panels areas back to the manifolds.
The only way I can see doing it is to run the leaders to the area of the panels prior to insulating and then have a splice/joint in the tubing at the entry location of the panel. I know you are never supposed to have joints in concrete panels, but is it acceptable to have joints in ceiling panels (since they would always be reasonably easy to access down the road in case of an issue).
If not then ???
Appreciate any insight from those that have worked with ceiling panels.
Once I get this figured out I then have to determine a way of installing 200+ wafer style ceiling LED recessed light drivers through all of the above in a way that will satisfy the electrical inspector. :-(
Take care and stay safe!
