The QFFG Series are neoprene-coated fiberglass mounts used in floating floor systems. The QFFG Series offer constant natural frequencies over the entire load range. These mounts are designed for air spaces of 2", and are best used in applications where improved isolation performance and low cost installation is required.                          

The architectural design consists of two floor slabs - the floating or isolated bearing slab and the structural floor slab. The QFFG Series serve as a permanent load bearing resilient material that connects the two slabs and provide positive air gaps between two-floor systems. This series is also available factory mounted to 4' x 4' sections of pressure treated plywood, providing the contractor with their first course of underlayment.                                                                                             

The QFFG Series combine simplicity with the long-lasting performance of neoprene-coated fiberglass and very simple, low cost installation.
