Akustik Floor Spring AFS

The Akustik Floor Spring AFS combines Sylomer® microcellular polyurethane with calibrated coil springs to achieve elevated acoustic isolation values across both low and high disturbing frequencies — a performance level not achievable with elastomer alone.

System Overview How the AFS Works Coil spring and Sylomer® working in series for broadband isolation.

How It Works

• Coil spring handles low-frequency isolation — effective against heavy impact and mechanical excitation
• Sylomer® element attenuates mid and high frequencies where springs alone are less effective
• The two elements in series provide broadband attenuation not achievable with a single material
• C-profile galvanised steel supports (75/50/2mm) recommended for installation

Typical Applications

• Floating floors above mechanical plant rooms
• Recording studios and broadcast facilities requiring the lowest achievable noise floor
• High-specification residential and hotel floors above heavy vibration sources
• Floors subject to both low-frequency impact and high-frequency structure-borne noise

Light Load · 25–50 kg/m² AFS 25 · AFS 50 Black and blue spring variants for lightly loaded floating floors.

Medium Load · 75–100 kg/m² AFS 75 · AFS 100 Grey and beige spring variants for standard screed and concrete floating floors.

Heavy Load · 150–250 kg/m² AFS 150 · AFS 250 Black and red spring variants for heavy screed and industrial floating floors.

Base Options Standard vs. Sylomer® Base Two base configurations for different high-frequency attenuation requirements.
