Foam cutback preparation for overlapping joint
The pre-cut is made on the underside of the panel to facilitate the removal of the insulation.
If identical sheets are used (all with right-hand overlap or all with left-hand overlap), the laying direction must be reversed when covering the second roof pitch.
To maintain the same laying direction, sheets with left-hand overlap must be used for the first roof pitch and sheets with right-hand overlap for the second roof pitch.
