Acoustic Performance Explained
How Do Acoustic Accordion Doors Reduce Sound?
Acoustic accordion partitions reduce sound through a combination of:
- Mass-loaded panel construction
- Internal acoustic insulation layers
- Full-perimeter sealing systems
- Decoupled panel movement systems
What is STC?
STC (Sound Transmission Class) measures how well a partition reduces airborne sound such as speech.
- Lower STC → minimal sound control
- Higher STC → greater speech privacy
FoldaSil® Acoustic Accordion Doors are available in multiple STC performance levels, allowing each system to be tailored to project-specific acoustic requirements.

FAQS
What are acoustic accordion doors?
Acoustic accordion doors are movable partition systems designed to divide interior spaces while reducing sound transfer. They function as flexible room dividers that provide sound control and speech privacy in commercial and institutional environments.
How effective are acoustic accordion partitions at reducing noise?
The effectiveness depends on the system’s STC (Sound Transmission Class) rating, construction, and sealing system. Higher-performance models can significantly reduce speech and background noise between adjacent spaces.
What is the difference between STC and FSTC?
STC measures sound reduction in laboratory conditions, while FSTC (Field Sound Transmission Class) reflects real-world performance after installation. Both are used to evaluate how well a partition reduces airborne sound.
What is the difference between single-wall and dual-wall accordion partitions?
Single-wall systems provide moderate sound control and are ideal for general use, while dual-wall systems offer higher acoustic performance and improved sound isolation, making them better for environments requiring greater privacy.
Which accordion partition should I choose?
- ANC-AP33 → light to moderate sound control
- ANC-AP39 → moderate sound control with durability
- ANC-AP40 / AP40-2 → higher performance for commercial spaces
- ANC-AP41 → premium acoustic control for privacy-critical environments
The right choice depends on your noise level, space size, and privacy requirements.
Are acoustic accordion doors soundproof?
Acoustic accordion doors are sound-reducing, not completely soundproof. However, high-performance systems like dual-wall partitions can significantly reduce speech transmission and improve privacy.
Do FoldaSil® Acoustic Accordion Doors help with energy efficiency?
Yes. The full-perimeter seal system helps minimize air transfer between spaces, reducing heat loss and uncontrolled airflow. This added benefit complements the partition’s role in noise proofing a door and improving overall space performance.
