OPTIONS IN WALL/CEILINGS SOUND ISOLATION SYSTEM SUPERSOUNDCLIPS MOUNTINGS!

SSP-1 sound isolation clips, AS-1 Soundclips, RC-1 & 2 Resilient channel DWFC Soundproofing materials.

Sound control has become a serious issue in the war against noise pollution A typical wall or ceiling will allow ordinary conversation to be heard through it.

Elements of a wall or ceiling in typical home or office construction are:

A structure (wood or metal, called studding if for walls, joists if for ceilings), to support the walls and ceiling.
Panels of wallboard attached to the structure with fasteners such as nails or “drywall screws”. Steps involved after fastening the panels to the walls are:
Filling the gaps and crevices of the panel joints with “mud”.
Taping the joints and covering with “mud”.
Sanding the surfaces smooth and painting to suit.
Depending on various factors such as the thickness and quality and the denseness of the panels, such a wall will still allow normal conversation to be heard through it.

Resiliently mounted wall and ceiling Gypsum board (Drywall/ Sheetrock/ Wallboard) is fast becoming a building industry standard for reducing sound transfer between rooms in homes and offices. By isolating the mounting of the wall panels from the studding, (or joists), annoying sound travel through the wall to the other side is greatly reduced. (Loud shouting is not heard). This is a real plus for apartments and rooms that should be quiet, such as bedrooms, for instance. Several methods to provide resilient mounting of these building wall and ceiling panels using Drywall Furring Channel (DWFC) have been provided to the marketplace.

Depending on cost, labor and desired level of sound control through a wall or ceiling assembly, there are now choices for reducing sound.

SSP channel mounts. DWFC channel is mounted with 2 screws with this SoundClip.  Made in USA. Pix with DWFC installed. (U.S. Design Patent Pending).

 

Aero-Support Sound Isolation Mounts. A very new, (Patent Pending), mount with numerous advantages over the other units. Has 3 rubber mounting grommets. Made in USA.. (Works with DWFC).  Use for walls.

COST: Speaks for itself: Certain cost advantages may be outweighed by other considerations.

AVAILABILITY: Due to various market constraints, such as stocking and shipping. Some products may not be readily available when needed. This can have a very negative effect on a construction/remodel project, which is normally working on a pre – determined schedule. This should be considered first, before picking a product to use. Obviously, if it’s not available, you can’t use it!

PERFORMANCE: Of course one of the prime requirements is to reduce sound transfer. How well each product does this is a matter of design and practical experience, not necessarily lab reports, which many times are heavily biased. The A-S clip performs better by using a smaller footprint than the others. It will mount Drywall Furring Channel, (DWFC) as well as Resilient Channel: (RC-1). (Walls only). It’s advanced design allows it to be used in many different ways. It also has a unique “pull-tite” grommet mounting system.

EASE TO INSTALL: Some mounts with one screw, the SSP with 2 and the A-S with 1, 2, or 3, depending on the installation. The first two products mentioned are somewhat limited except for the most basic installations. Their typical use is to simply screw them to the face of the wall/joist/stud for the channel/drywall to be mounted. Unfortunately, this can cause a serious loss of living space due to a “build-out” of several inches. (And problems where walls meet doorways/windows, etc). Their large rubber mount area passes sound better than the smaller mounting areas of the A-S clip.

VERSATILITY : Unless special mounting brackets are constructed or purchased to use with the first two mounts mentioned, the basic units are not suitable for many projects where build-out is an issue. This adds greatly to the cost, not only for the purchase of these extra parts, but for the added labor for installing them. The A-S mounts in various positions and ways. No added parts are needed.

NUMBER REQUIRED :A second issue with these types of mountings is the number required to support the wall/ceiling assembly, which many times consists of other elements for additional sound control such as lead-lined drywall, sound-(deadening) board, Mass Loaded Vinyl (MLV), Homasote Panels, etc. A rule of thumb is 1 mount per each 4 sq. ft. of wall or ceiling, adding more depending on the situation. The A-S mount system does not have this limitation, mounting as much as 6-8 sq.ft. of wall paneling, regardless of the number of sandwich panels and weight involved, thereby reducing the number of units needed, slashing the cost.

CODES: Building codes are always a issue with commercial installers and contractors, especially if there are wall and ceilings with fire code requirements or primary structure, load bearing walls, etc. Each job is different but many times sound control, not structure, is the primary concern and only issue. Then, such codes are not an issue. The X’s in the chart above are an indication of the level of approvals obtained for these products to date. Obviously, the longer the product has been on the market, the more time has passed enabling testing to be done to prove meeting the many various codes. While there is a great difference in the design and method of construction of these products, they are all basically made of the same two materials: steel with some kind of rubber (type) mounting grommets. Therefore they will all eventually reach the same level of compliance, it just takes more time.

TIP: If you decide to not use soundclips or resilient channel, at least do the “Poor Mans” soundproofing by padding the surface of the studs/joists with special soft tape before installing your drywall panels.
