This is a recent 2024 job, where we replaced a slightly sloping glass conservatory roof with a warm roof.
The warm roof is a solid wood frame, covered externally with marine ply boards, then firestone rubber to keep it dry.
Internally, insulation is added in the frame structure, then plaster boarding then a plaster skim.
The end result is an immediate warmer room when chilly, and less heat when hot outside.
