the end flaps against the sheathing (Fig 13.4).<br />

tape to the jamb and wrapped at least 2 in. (51mm)<br />

continues up past the head opening at least 4 in.<br />

Weatherproof the Sheathing Joints and Corners:<br />

Apply WeatherSeal in minimum 5 in. (127mm) wide bands<br />

centered over sheathing joints and immediately center<br />

and embed Parex USA 396 Sheathing Tape into the wet<br />

WeatherSeal. A 4 or 6 in. (10 or 15mm) wide drywall knife<br />

works very well to adhere the 396 Sheathing Joint Tape to<br />

the wet WeatherSeal. All inside and outside corners shall be<br />

sealed in the same manner. (Fig 13.5).<br />

Parex USA Flashing Membrane may also be used for<br />

protection of the rough openings. Primer may be required on<br />

certain substrates.<br />
