Add insulated metal faced panels to the exterior walls of a curling rink arena.
Existing 25 yr old building walls are uninsulated painted concrete block without a vapour barrier. Structure is a pre-Eng steel frame with insulated metal roof.
Building located near Toronto Canada.
Building is maintained close to 40f year round.
Owners have installed new dehumidification equipment and now want to upgrade the walls insulation and seal air infiltration.
The preference would be to use metal faced insulated panels of 5" thickness providing an R of 20.
1) panels could be installed tight to existing block or fastened to metal furring leaving a 1" space between block and inside metal face of panel.
2) considering that summer months will be the worst conditions of operation (cold inside hot outside). I would elect to caulk the exterior face joints between the panels as well as around the perimeter to create a vapour barrier on the warm face.
Optionally, panels could be left uncaulked and not creat a VB at all.
What is the best scenario here?
