Soundproof Doors: Acoustic Door Solutions for Commercial & Residential Projects
Why Standard Doors Fail at Sound Isolation
A standard hollow-core door provides STC 20-25. True soundproofing requires an engineered system: high-mass core, perimeter acoustic seals, automatic bottom seal, and sealed frame-to-wall connections. Jusen engineers each element to hold its rated performance.
Understanding STC Ratings
| STC Rating | Performance Level | Typical Application |
|---|---|---|
| STC 25-30 | Basic | Standard interior doors |
| STC 30-35 | Moderate | Residential bedrooms |
| STC 35-40 | Good | Hotel guest rooms |
| STC 40-45 | Very Good | Hotel corridors, conference rooms |
| STC 45-50 | Excellent | Recording studios, luxury suites |
| STC 50+ | Professional | Broadcast facilities, music studios |
How Our Acoustic Doors Are Engineered
High-Mass Core Construction
High-density particleboard, mineral-filled composite, or laminated timber. Acoustic door weights range from 60-120 kg.
Perimeter Acoustic Seals
Compression gaskets around all four edges. Even a 1mm gap can reduce STC by 10 points.
Automatic Bottom Seals
Drop-down seals that create an airtight barrier at the threshold. Essential for STC 40+.
Heavy-Duty Ball-Bearing Hinges
Ball-bearing hinges rated for 100+ kg ensure smooth operation and maintain seal alignment.
Acoustic Thresholds
Tight seal at the bottom without impeding wheelchair access. ADA-compliant options.
Sealed Frame-to-Wall Connection
Acoustic caulk prevents flanking sound transmission. Installation instructions specify sealant types.
