About Quietzone™ What is the Quietzone™ System?
The family of Quietzone™ products consists of: Quietzone™ Framing, Quietzone™ Acoustic Batts, Quietzone™ Floor Matt and Quietzone™ Caulking, Quietzone™ ? Acoustyle Residential Wood Ceiling System and Quietzone™ ? Solserene Fabric Ceiling System. Depending on where Quietzone™ products are used, they can significantly reduce the transmission of noise between spaces and/or enhance the sound quality within rooms where reverberation (or echo) becomes problematic. Combining various Quietzone™ ? products can greatly increase the effectiveness of noise reduction transmission when compared to conventional room construction.
Do I need to use all 3 parts of the Quietzone™ wall system to obtain better noise control?
No, it is not necessary. Other brands of batt insulation and caulking can produce similar STC ratings. If choosing a different insulation it must fill the stud cavity and be of similar density. If choosing a different brand of caulk, make sure it is non-hardening and maintains its elasticity over time.
How does Quietzone™ Acoustic Wall Framing system work?
The Quietzone™ stud is designed to be 1/8" wider than a conventional stud. This allows the attached drywall to float outwards from the top and bottom plate, effectively breaking the sound vibration path through the wall. Quietzone™ ? Acoustic Caulking is used to seal the gap between the drywall and top and bottom plate. This assures that the wall assembly is well sealed and able to vibrate freely. Quietzone™ caulk is designed not to harden and will remain elastic over time.
What are the load carrying capabilities of Quietzone™ Acoustic Wall Framing?
For exact load carrying capabilities, refer to the design and installation brochure. In general, 2x4 Quietzone™ Acoustic Wall Framing has load carrying capacities of nominal 2x3 #2 SPF lumber and 2x6 Quietzone™ ? Acoustic Wall Framing has load carrying capacities of nominal 2x4 #2 SPF lumber.
Where is Quietzone™ Acoustic Wall Framing currently being manufactured?
Quietzone™ Acoustic Wall Framing is being manufactured in Ontario, Canada.
Does QuietZone™ Acoustic Wall Framing have an International Code Council Evaluation Service (ICC-ES) or Canadian Construction Materials Centre (CCMC) Evaluation report?
No, QuietZone™ Acoustic Wall Framing does not require either report. It is made from a structural piece of #2 certified finger-joint lumber and a resilient member of LVL joined with a metal clip. Finger-joint lumber can be used interchangeably with solid sawn lumber as long as it bears an appropriate grade stamp from an approved grading agency. National Design Specification. 2005. Paragraph 4.1.6. American Forest and Paper Association states "design values for sawn lumber are applicable to structural end-jointed or edge glued lumber of the same species and grade". And for the LVL resilient member, the ICC-ES report can be found on the Webpage www.icc-es.org. Search evaluation reports for ESR-1898. For more information see our ICC-ES Code Acceptance letter on our Webpage under the link "Literature".
Gypsum Wallboard (Drywall) Can I hang multiple layers of gypsum wallboard on the Quietzone™ Acoustic Wall Framing?
Yes, just make sure that drywall screws used on the resilient member side of the wall only penetrate into the resilient member and not all the way into the structural member. The recommended screw length is drywall thickness plus ½".
Can I tape the drywall joints at the junction of the wall and ceiling?
Yes, you can finish the drywall just as you normally would. The only difference is to make sure Quietzone™ Acoustic caulk is applied along the corner of the first layer before applying the second layer of drywall.
What is the effect of adding additional layers of gypsum wallboard on STC ratings?
STC ratings are not derived by adding gypsum wallboard piece by piece, but by testing the wall system as a whole in a laboratory setting. How much noise attenuation is gained from adding additional layers of gypsum board will depend on how the wall is constructed. Conventional studs easily conduct noise vibrations from one side of the wall to the other. Quietzone™ studs isolate and break noise vibrations throughout the wall thus significantly reducing noise transmission over conventional construction practises. For additional guidance on the effects of gypsum on wall assembly STC ratings, please see the Gypsum Association Website.
What is Type X gypsum wallboard?
Type X gypsum wallboard is specially formulated to provide superior fire resistance over regular gypsum wallboard. As a result, it is typically heavier than regular drywall.
Quietzone™ Acoustic Caulking Do I need to use Quietzone™ Acoustic Caulking?
Yes, caulking the system prevents flanking and therefore is required for acoustical performance.
Installing Quietzone™ Acoustic Wall Framing How do I install Quietzone™ Acoustic Wall Framing?
Quietzone™ Acoustic Wall Framing is a fully assembled wall stud. It installs just like regular wall framing with no additional materials or labour required. Just make sure that the resilient member is proud of the top and bottom plate by 1/8" thus effectively breaking the path for sound and providing lasting sound isolation.
Is Quietzone™ Acoustic Wall Framing suitable for exterior walls?
Quietzone™ Acoustic Wall Framing has been designed for interior walls only. No acoustical testing has been done on exterior wall applications. However, theoretically the product could be used for exterior wall applications.
Can I use Quietzone™ ? Acoustic Wall Framing as a ceiling?
No, Quietzone™ Acoustic Wall Framing was designed for use as a wall stud. Quietzone™ framing is graded for vertical use only and should not be used in bending applications.
Do door installations require double resilient studs?
No. See detail QD1 and QD2 on the Design and Installation Guidelines. The Quietzone™ framed doorframe is stacked next to a regular piece of dimensional lumber acting as the king stud. Do not attach the drywall to the regular dimensional lumber stud as this will provide a path for the sound vibrations and affect the acoustical properties of the wall.
How do I install electrical outlets?
See detail QM1 on the Design and Installation Guidelines. To reduce the detrimental effects of electrical wall penetrations, it is recommended that electrical boxes not be installed back to back within the same stud cavity. Plugs and switches should be spaced a minimum of 36". All other wall fixtures should be spaced a minimum of 24". Ensure all electrical penetrations of the wall are sealed with Quietzone™ Acoustic Caulking.
I am building a wall that ends at the attic rafters. Can I trim Quietzone™ Acoustic Wall Framing at an angle to accommodate a pitched roof?
Yes, Quietzone™ Acoustic Wall Framing can be trimmed. Ensure that the resilient member is always 1/4" shorter than the structural member on both ends to yield the appropriate sound isolation properties.
Is QuietZone™ Acoustic Wall Framing suitable for pre-fabricated wall framing and use in panelized wall manufacturing?
Yes. QuietZone™ Acoustic Wall Framing was used in a pre-fabricated wall application on the job site of Robson Communities, Arizona (see project profile). QuietZone™ Acoustic Wall Framing has also been tested in panelized wall facilities and was found to be easy to assemble.
Acoustics What is a decibel (dB)?
A decibel measures loudness or intensity of sound. This scale shows decibel measures for a few sounds we encounter everyday.
What is STC?
Sound Transmission Class (STC) A single number rating based on a laboratory test of a wall, floor or ceiling partition indicating how well sound is reduced from one side of the partition to the other. For example, if a wall has a rating of STC 45, it will give potential users of this wall design an indication of how well this partition will perform against a sound source such as a saw (105 dB), noted below. It is important to remember that STC is a basic indicator of performance. It does not indicate how well the partition performs at all frequencies a sound or noise source is comprised of. So in a very basic sense, a STC-45 wall will reduce the sound level of the saw from 105 dB to 60 dB. To really see how much sound or noise a partition will reduce, we need to look at the full spectrum of frequencies that the noise is made of and determine how the partition filters these frequencies through it. A partition's ability to reduce noise is measured in decibels (dB) and these dB losses (called Transmission Loss) are associated with the frequencies making up the sound. The Transmission Loss at each frequency can tell us how well a partition reduces noise at that specific frequency (say 100 Hz or at 250 Hz.). STC, so to speak, puts us in the ballpark while Transmission Loss gives us all the play by play details.
What is an acceptable STC rating?
Building codes in the USA dictate a minimum laboratory STC rating between multi-family units of 50. However, studies indicate that a STC rating of 55 may be more acceptable to the general public to reduce noise complaints. In general, a 10-point increase in STC will cut the perceived noise level in half. Below are some STC ratings for typical wall constructions and Quietzone™ Acoustic Wall Framing.
STC Rating Wall Description Speech Music STC-29 Typical Interior Wall Normal speech heard Music easily heard STC-35 Sealed (QZ caulk) Wall, no cavity fill Loud speech heard Loud music easily heard STC-39 Std Sealed Wall w/ QZ Batts & QZ Caulk Loud speech blurred Loud music muffled but easily heard STC-49 2x4 Single layer drywall w/ QZAWF Loud speech barely audible Loud music greatly reduced. Bass is noticeable. STC-60 and greater 2x6 Double layer drywall w/ QZAWF Loud speech inaudible Loud music inaudible. Bass barely audible How do wall field STCs differ from lab STCs?
Theoretically, field STC and lab STC should be the same. Typical causes for field STC to be lower than lab STC is due to flanking losses from adjoining floors, ceilings and other walls and/or leaks through the wall caused by discontinuities in the wall such as electrical outlets. Poor construction practises can lead to field STC ratings to be up to 20 points lower than lab STC ratings.
What is the reduction STC rating if the gypsum wallboard touches top or bottom plate in the Quietzone™ Acoustic Wall system?
Having the drywall simply contact the top and bottom plate could result in a 1-2 STC reduction. If drywall is physically attached to the top or bottom plate (ie nailed), this could result in up to a 3 STC point reduction. It is very important when installing gypsum wallboard that it does not touch the top or bottom plate directly, but is sealed to the top and bottom plate using Quietzone™ Acoustic Caulking for good sound performance.
How does stud spacing affect STC?
STC ratings will be slightly reduced with reduced spacing of studs.
Cost How much does Quietzone™ Acoustic Wall Framing cost?
Ballpark figure of 2 to 3 times framing lumber. Call 866-864-5710 or send an email to Quietzone.framing@tembec.com for a quote including freight for your project.
How does the Quietzone™ Acoustic Wall Framing compare to other framing methods?
Quietzone™ Wall Framing provides numerous advantages over conventional noise control systems. Quietzone™ Framing uses less floor space over other partition wall systems of equivalent STC performance. Allowing more living space. Quietzone™ Wall Framing also uses less material and labour than most conventional constructions providing additional savings. For example, STC 50 and 55 walls built with Quietzone™ Acoustic Wall Framing at 24" o.c., are competitive with alternative systems of building noise control walls. Last, but not least, Quietzone™ Framing is easy to install and will not deteriorate in acoustical performance over time, unlike some other noise control components.
