F-300M for sound suppression

Product catalog summary

Introduction
Fibertex F-300M is a product designed for impact sound suppression in multi-storey buildings. It is particularly effective in areas such as wet rooms, stairwells, and corridors where sound requirements are stringent.

Specifications
The product achieves a weighted impact sound suppression of approximately ∆Lw 15 dB when used as an underlay on a floated concrete floor. This performance has been verified through testing in a multi-storey building in Odense, Denmark, where impact sound levels were reduced from 79 dB to 54 dB, achieving a suppression of 25 dB.

Standards
The impact sound suppression is calculated according to EN ISO 717-2:1997 standards, ensuring compliance with international acoustic requirements.

Installation Procedure
1. Lay two layers of Fibertex F-300M over the concrete surface, ensuring any scarf-joints are staggered.
2. Cover the Fibertex with a layer of plastic sheeting to prevent mixing with the concrete.
3. Pull the upper layer of Fibertex and the plastic sheet up along the wall to ensure separation between the wall and floor.
The product is available in rolls of 2×25 m and 5×100 m, allowing for quick and flexible installation using a Stanley knife.

Benefits
Using Fibertex F-300M improves indoor climate by reducing noise levels, which is crucial for comfort in residential and educational buildings.
