Sonex Curtains – Barrier Backed

Sonex-Curtains-–-Barrier-Septum-1-1

SONEX Curtain BB is a composite that features sound absorptive willtec® foam quilted with a vinyl facing on one side, bonded to a reinforced noise barrier material. This product provides both excellent sound transmission loss and sound absorption performance.

SONEX Curtain BB is ideal for use as barriers, independent walls, partitions or acoustical screens to isolate noisy machines or specific areas. The combination of barrier and willtec foam contains and absorbs noise in almost any manufacturing environment where durability and dependability are required.
 
SONEX Curtain BB can be custom manufactured to integrate as a complete acoustical enclosure system giving access to machines or work cells. They are also available in 25′ rolls with finished or unfinished edges.
 
SONEX Curtains BB are easy to install. Curtain hardware, hanging mechanisms and configuration options include clear vinyl windows, grommets, hook and loop fasteners, doors and sliding tracks. The standard facing material is a vinyl-coated fabric in grey, white, tan or black.
