The ANFF Series are adjustable neoprene floating floor isolators that provide an exceptional solution for high frequency noise attenuation. The ANFF uses a neoprene compound within a cast housing that is positioned within the floating slab, while still accessible from above for later adjustments to the slab  height.                                                                                  

The design consists of two reinforced concrete slabs - the floating or isolated wearing slab and the structural floor slab. The ANFF Series serve as a permanent load bearing resilient material that connects the two slabs while isolating the floating floor from the base floor. A bell-shaped housing ensures that the concrete load is evenly distributed throughout the mount. The housing allows for floors from 3" to 12" thick and the mount can accommodate air spaces from 1/4" to 4". A bonded metal load plate is shaped to ensure that the neoprene element remains centered within the housing. ANFF isolators also include "chairs" that position and support rebar in the floating floor and assist in jacking the floor.                                                                                       

The ANFF Series combine positive, adjustable air gaps with the proven isolation characteristics of a neoprene element. The ANFF Series offer simple installation and long-lasting performance.
