A waterproof insulating panel for use between a waterproofed exterior sheathing and an exterior stucco cladding of a building, comprising:
- a plurality of insulating panel sheets of expanded polystyrene (EPS) closed cell foam, each sheet having a roughened back side and a smooth front side and having no drainage plane or surface voids on either side;
- a first, liquid coat of silicone elastomeric (SE) roof coating applied to the roughened back side of each insulating panel sheet;
- a layer of the coated insulating panel sheets pressed against the exterior sheathing and joined edge-to-edge at a seam to cover the exterior sheathing with a plurality of insulating panel sheets while the first, liquid coat of SE roof coating is still wet;
- a strip of SE roof coating applied along each seam on the smooth front side of the layer of insulating panel sheets;
- a first waterproof wrap formed of anti-fracture fabric (AFF) bonded to the each coated seam to form a plurality of sealed seams;
- a second waterproof wrap formed of anti-fracture fabric (AFF) coated with SE roof coating and disposed around openings for utility lines;
- and
- a second liquid coat of SE roof coating is applied to the front side of the layer of insulating panel sheets including the sealed seams;
- wherein
- the combination of the layer of insulating panel sheets coated on the back and front sides with SE roof coating and the sealed seams provides a waterproof insulating panel that is free of interior spaces and gaps and fully sealed against water.
