Noggin out between the rafters ensuring the noggins are flush to the top and bottom of the crown ends. (Noggins can be 3" X 2" timber or 70mm steel partition track.

Mechanically fix the Firefly Plus 60 to the noggins using 25mm X 0.6mm steel hoop iron using 32mm drywall screws @ 100mm centres.

Overlay the top and front of the Firefly Plus 60 with Intubatt FZ. Adhere all joints with Intucoat Mastic and screw fix through the Intubatt FZ and Firefly Plus 60 into the timber noggins using 70mm drywall screws and penny washers @ 600mm centres.

Overcoat all joints, edges and screw/washer heads with Intucoat mastic ensuring a sea of white and no gaps on completion.

Lay sarking over the top of the Intubatt FZ ensuring ample overlap is left around the perimeter. Once the gutter is installed the sarking can be trimmed to length allowing the standard 50mm lap into the gutter.
