Made of long-lasting EPDM rubber, Auralex U-Boat Floor Floaters are our proprietary U-shaped channels used to support framing members and float (isolate and decouple) them from the surrounding structure. With the help of U-Boats, a floated room features greatly improved transmission loss (isolation) and low-frequency definition (translated: a tight, floated room will always sound better!).

U-Boats are molded to fit around the edge of any 2 by X joist. To figure out approximately how many U-Boats to get, just multiply the total square footage of the area you want to float by two-thirds. Auralex U-Boats are the industry's most affordable floating solution and are much easier to use than those exorbitant "pucks" that have been used in the past.

Size: 2-1/8" wide x 1-1/2" high x 2" long
Thickness: sides=5/16" and base=1/2"

Auralex U-Boat Spacing Guidelines:

  • If Joist Spacing is 24" o.c.: Space U-Boats 16'' o.c. along the joist minimum and not to exceed 24'' o.c. 
  • If Joist Spacing is Between 12''-16'' o.c.: Space U-Boats 16'' o.c. along the joist minimum and not to exceed 32'' o.c.
  • Most (>99%) of applications will work fine with 16'' o.c. spacing of U-Boats along the joist. Spacing further apart will improve low-frequency isolation below 40 Hz. However, spacing should never exceed 32'' o.c.

    *o.c. stands for ''on center'' and represents measuring spacing from center-to-center of, say, joists or studs (or U-Boats). This is to prevent confusion caused by sometimes erroneously measuring from edge to edge.
