Rubber Joist Isolation Clips are used as a highly effective way to isolate and decouple floor joists from the subflooring.  By decoupling the floor joists, the room is able to be isolated from its surrounding structure.  Rubber floor joist isolators simply snap onto any "2x" joist or stud (2x4, 2x6, etc) and do not require any fastener that could harm the isolation value.

Rubber Joist Isolation Clips are used primarily in floating floor applications which are very popular in sound studios, recording booths, control booths, home theaters, and speaker floor mounts.  The floor joist isolators would be installed on the bottom of the new floating floor joists when they are being laid down.  Joist Isolators are also the ideal decoupling method for home theater raised platforms.

Rubber Joist Clips are made from Vibrasorb EPDM rubber that is precision cut to fit snug on any "2x" joist without any fastener.
Dimensions of the clips are 2-1/8" W x 2" L x 1-1/4" H.  The thickness of the rubber between the joist and the subfloor is 1/2".  Maximum load per joist clip is rated at 750lbs.

Rubber floor joist isolators simply snap onto the joist and should not be glued, nailed, or screwed into the wood.  The clips should be installed at both end of every joist and additional clips should be spread out every 16" along the joist.  Project estimation is approx 65 clips per 100sf of floating floor.

    Floating floor isolation clips, perfect inexpensive solution for helping to soundproof and reduce vibrations

    These c-channel isolation pads are simple, rugged and provide excellent sound/vibration isolation at a low cost. I used these for my home theater riser and stage construction project on top of a concrete slab floor. after installing these on the underside of the joists, there was almost zero noticeable contact vibration and the resonance issue I was experiencing with low frequencies almost completely disappeared.
