Description

The HushFrame Raft Connector is the newest invention for decoupling drywall from wall and ceiling structures. Decoupling is not a new concept in sound isolation, but the Raft provides unique benefits over competing products. This wood based product is connected between a soft, yet extremely strong, rubber silicone. The energy from sound is lost in the transfer from the front of the Raft to the base of the Raft via the rubber silicone. The end result is significant isolation gains in STC and IIC for both walls and ceilings, even in the most basic of assemblies. No other products are needed to achieve ratings that meet or exceed building code for STC and IIC. Simple fool proof installation for a simple assembly with exceptional performance!

Introducing the HushFrame Raft Connector

Versatile In Ceilings and Walls

The Rafts can be installed to the side of the joists either flush or recessed. Recessed installation allows the furring to run parallel with the framing saving up to 3/4" of headroom or floor square footage without losing any performance! The Rafts can also be trimmed to fit tighter spaces if needed. This saves money and simplifies your product purchase.

Installation

Attach each Raft to the side of the joist or stud with the base of the Raft flush or slightly recessed. A staggered diamond pattern is used to help distribute weight to each joist. The general pattern is 1 Raft every 32" in rows that are up to 24" apart. From there, attach a standard 1x wood furring or 25 gauge metal furring hat channel to connect each Raft. Drywall then fastens to the furring.

Estimating

The number of Rafts required depends on the spacing utilized and complexity of the ceiling or wall. Refer to the diagrams for proper spacing. Generally 1 Raft is needed for every 3.5 square feet of surface, for both walls and ceilings.

Main Features of the HushFrame Raft

Significant improvement to STC and IIC in wood, steel, and concrete structures.
Low profile: Install to the side of the joist to lose between 1/4" to 1" of headroom.
Allows both wood and metal furring to fasten between the Rafts and the drywall.
Minimal cost: Meet building code requirements with just the Raft system and single layer drywall.
STC, IIC, UL, and structurally tested. This product will keep your assembly quiet and safe!

HushFrame Raft Spacing Diagram

HushFrame Raft Installation Spacing Diagram

Spacing for both perpendicular and parallel furring

The HushFrame Rafts can be installed so that the furring runs perpendicular to the framing or parallel to the framing in structures with 16", 19", and 24" on center framing for both walls and ceilings. We strongly recommend the staggered layout if you choose an spacing that does not require a Raft on each stud or joist. The staggered layout will help distribute the weight across the surface and improve performance in lower frequencies.
