Installation guide
Sill & Jamb corner moulds
When the openings are formed in the membrane by cutting on a 45° diagonal from each corner of the penetration, the flaps of the cut must be folded inside the opening and stapled to the penetration framing. Excess underlay may be cut off flush with the internal face to the wall frame.
The corner moulds must be stapled tightly to both sill and jamb corners; is not necessary to install corner moulds in the lintel and jamb corners.
When corner moulds have been stapled, tape flashing can take place.
