JOINT SERIES SSMwall-to-wall | 1"-24"
JOINT SERIES SSM-Mwall-to-ceiling | 1"-24"
Watertight Seismic Joints | 100% Moisture Barrier Protection with styleSEAL
While exterior profiles may appear visually identical, the critical difference lies within the internal membrane architecture. Standard expansion covers feature segmented moisture gutters for cost-efficient interior dry areas. Systems with the "PC" suffix are assembled with continuous vulcanized styleSEAL membranes running the full length of the joint run to guarantee zero moisture penetration across parking decks and podium slabs.
Watertight Pan Tray Floor Joints (JPC-PC)
The JPC-PC Series combines the invisible flooring infill capability of recessed pan trays with 100% continuous moisture barrier protection using the styleSEAL membrane. Prevents moisture intrusion between floors while absorbing dynamic multi-directional structural drift.
