Sauna roof modifications

An amazing effort was made last year to build a sauna, based primarily on recycled timber. This year we wanted to make some improvements.
The roof needed the most work, so we reinforced it, and added interior and exterior panels to create an insulated cavity roof.

Reinforcing the roof with beams between the rafters
Half of the ceiling panels in place, view out the doorway to the firepit
All ceiling panels in place
Cavity created between interior ceiling panels and exterior panels,
then filled with rockwool insultation
On top of the roof completed with exterior panels

Next step is to add breathable membrane, and feather-boarding to finish the roof. Then we will be on to sanding and treating the rest of the sauna and door construction.
