Balco USA, Wichita, Kan., has introduced the Michael Rizza Partition Closure System (PCS-Series), a vertical silicone compression seal and sound transmission dampener that’s molded into a single 100-foot-long length. The aesthetic PCS-Series is a product designed for vertical junctures and joints between the ends of partitions and curtain walls and glazing for office facilities, hotels, hospitals and other commercial buildings.
The 100-foot length of the PCS-Series reduces multiple splicing associated with other partition closures. The 100-percent silicone construction is cut onsite with a utility knife and has the flexibility to fit into two-inch-wide expansion joints between exterior glass or mullion curtain walls and CMU or drywall partitions. The installation process is completed with a one-step silicone rubber building joint sealant, such as Dow Corning 790, which complements its abatement of sound/vibration transmission, thermal transfer and dirt/dust infiltration.
The one-piece, bellows-like design consists of two hexagonal and two trapezoidal-shaped chambers that allow the PCS-Series to expand and contract within a ±1/2-inch range without the use of mechanical springs or parts. The open chambers give the PCS-Series sound reduction qualities of up to STC-58, depending on single or double-sided installation configurations.
An optional 10-foot-long anodized aluminum Tube Channel Base Member (PCS-1B) and a C-Channel Base Member (PCS-1C) allow one side of the PCS-Series to be inserted and held securely. Both channels can accommodate larger joint openings and can be installed onto building materials with construction adhesives such as Liquid Nails or Sikaflex 1A.
The PCS-Series standard color is black, however colors from the Dow Corning 790 silicone color palette are available for matching building materials.
Other features of the PCS-Series:
- Doesn’t lose flexibility, deteriorate or fade because of the endurance of silicone and built-in ultraviolet light inhibitors
- Tested for cyclic movement under the ASTM E1399 Standard
- Contributes to Leadership in Environmental and Energy Design (LEED) credits
- Standard one-year warranty
