Thru-Wall Flashing Support System (TWFSS) consists of two parts; straight run and splines. TWFSS is used to bridge the cavity, supports flexible flashing membranes and ensures water reaches the exterior of the building.
Made of outdoor rigid PVC (free from plasticizers) TWFSS can be modified on the construction site to suit the varying depth of exterior walls, cut to length to suit building direction changes, and generally cut to suit the majority of wall designs and details.
Locations TWFSS can be installed:
-
High masonry wall intersecting a lower roof level
-
Top of concrete block foundation wall
-
Back of masonry brick lintel
-
Base of elevated metal siding
-
Base of elevated Exterior Insulating Finish System (EIFS)
