First Ever Non-Combustible Residential Acoustic Floor
Suitable for residential living areas where there is a requirement to reduce any acoustic sound transmissions
The AFD SilentStep® System is a residential acoustic hollow floor system designed to reduce airborne and impact sound transmissions whilst providing a solid-like feel floor.
A low embodied carbon system that can accept finishes directly, and is quicker to install than traditional cradle and batten. SilentStep® can easily overcome an uneven subfloor or when there is a higher void requirement.
