Hi there.
I am about to refurbish my flat foof with a fully adhered epdm membrane. But I also want to insulate as well.
At the moment it has a fibreglass covering and i will be using kingspan 100mm.
I know you can get special kingspan for this type of membrane, but you have to buy a whole pallet full, which is too much.
So this is my idea.
Leave the fibreglass where it is. Just clear the raised parts around the perimeter.
Lay down the insulation straight onto the old roof.
lay ontop of this some 11mm osb
screw down throught the boards and the insulation with some long screws.
glue the membrane down onto this new deck.
does this sound like a good idea?
all answers are much appreciated.
kind regards
