Product Highlights

Noise-Lock® Acoustic Windows

Crafted with precision-engineered seals and durable metal frames (aluminum, stainless steel, or galvanized steel), these high-performance windows are laboratory-tested for superior sound control. Available in STC ratings from 35 up to 59+, they’re factory-assembled for seamless installation and integration with any architectural system. 

Noise-Lock® Acoustic Doors

Reliable, fully assembled acoustic doors offering exceptional sound containment and fire safety. Available with 20-, 60-, 90-minute and 3-hour fire ratings, these doors cover STC ratings from 43 to 64 and include NIC 70-rated assemblies. Factory-crafted with split-frame design, acoustic seals, glazing, and hardware, they deliver both lab-tested performance and proven in-field noise reduction.

Super Noise-Lock® Steel Acoustic Doors

Cullum’s solution for the most demanding large-door applications—“elephant doors”—such as studios, hangers, testing facilities, and industrial settings. These robust steel doors deliver STC 50 to 55 (meeting NIC 45 to NIC 50 once installed) and accommodate openings over 14′ × 14′. Engineered for scale and durability, they’re custom-built for environments where standard doors simply won’t suffice.
