Looked at some classroom type buildings for a church yesterday. The buildings were built in the 60’s.
They had low slope roofs of 2:12. The roofs were standing metal seam or tar and gravel.
On the interior, they had cathedral ceilings with an exposed fiber / grass mat insulation visible from the room interiors. This fiber mat covered the under structure of the roof and extended to the eaves / fascia. Part of the original installation.
I haven’t seen this type material before and need to find out what it is. what it’s called, pro’s or con’s.
Any known problems - other than it droops and falls when the roof leaks !! :mrgreen:
I will defer to roofer, but need information for myself.
Any thoughts are welcome.
Thanks in advance,
