PRIVACY SPEAKER COVERS
Privacy Fire Rated Speaker cover is a dome-shaped intumescent cover which has been designed to help maintain the integrity of fire rated ceilings when penetrated by in-ceiling loudspeakers.
The unique design gives the architect, specifier and installer more freedom in speaker selection as the covers are suited to a wide range of recessed speakers.
The flexible and lightweight nature of the covers makes installation quick and easy, reduces the stress put on the ceiling and significantly reduces labor costs compared to standard dry-walled box constructions.
The sound absorbing properties of the Privacy Fire Rated Speaker Cover enhance the acoustic rating of the structure for crisp and clean sound.
The high expansion and insulating properties of the cover ensures that both, flame spread and heat transmission, are stopped for 60 minutes. The reduction of heat loss through the cut out of the ceiling can result in significant energy savings.
- Inside Height 8" Diameter 13"
- Inside Height 11" Diameter 15"
Available in two different sizes:
- Can be used with any speaker manufacturer.
- Enhances the acoustic protection of the ceiling.
- Easy Installation - can be fitted in seconds - no screws, drilling or additional sealant required.
- Significant Labor savings.
- Lightweight (approx. 2.5 lbs).
- Flexible material enables cover to be fitted around obstructions or retro-fitted.
- In a fire, the intumescent material expands 5 times of its original thickness, preventing flame spread.
- Easy to remove and re-install for speaker maintenance.
- Reduced heat loss through the speaker cut out in the ceiling.
- Maintenance free.
- 60 minute protection.
Privacy Speaker Cover Benefits
PRIVACY RECESSED LIGHT COVERS
Maintaining a sound rated ceiling with can lights continues to be a difficult task. Until now the options included building drywall boxes or even using a lightweight concrete layer on the ceiling above. Both options are very costly, and in some cases impossible to do after the fact.
In renovation projects, basements and new construction the conflict between much wanted recessed lighting and the ability to provide measurable sound control would preclude the use of recessed lights. For low ceiling projects surface mounted lights are not an option either.
From a Home Theater Builder on www.doityourself.com The trouble with the cans is that even if they're airtight, they're still basically big hollow sounding boxes that break the insulation layer and block very little sound themselves.
Finally there is a simple effective solution for any ceiling fixture that will insure that the sound rating will remain intact. Using Privacy Recessed Light Covers involves simply placing the cover over your recessed fixture and constructing your ceiling as you normally would. It's really that simple. The benefits are two fold, soundproofing and thermal insulation through the ceiling.
Privacy Light Covers are UL Rated, and will meet the International Building Code for any type ceiling. Both one-hour and two-hour fire rated covers are available. Additionally, we carry covers for ceiling mounted speakers, fluorescent light fixtures and more.
Privacy Recessed Light Cover Options
One Hour Fire Rated Light Cover:
PRLC-1 is an one hour rated cover for both 6" and 8" recessed lights. Meet the Fire Code and block noise in or out of the room in one step.
Two Hour Fire Rated Light Cover:
PRLC-2 has a two hour fire rating where commercial requirements cannot be met with PRLC-1. Same easy installation and the same excellent noise control in one step.
Performance Light Covers:
When a fire rating is not required we have a version of our covers that will provide the same benefits at a lower cost. Residential applications with blown insulation are typical with our Performance Light Covers.

PRIVACY REPLACEMENT DUCT
There are many applications where a silencer is not required. Typical occurrences are office to office noise in work environments. It not unusual with low cost office environments for the air space above a drop ceiling to open, not insulated, and for the ducts to be extremely lightweight. Voices from other offices or the hallway can easily migrate into the ducts and travel into your space.
In many cases we can reduce noise traveling through ducting by replacing a portion of the duct with Privacy Replacement Duct. These lightweight replacement sections are available 10' long, and are sized according to your existing ducts.
A perforated aluminum core is wrapped with a foil faced blanket of insulation to offer high R Value, and excellent noise reduction. Privacy duct is durable, easy to install, and will provide meaningful noise reduction in the voice ranges for all applications.

Recommendations;
- 1) Use a solid wood door; this is better than solid core, or exterior metal doors.
- 2) Wait until the floor covering is installed before you trim the door.
- 3) Make sure the door stops at sides and top are in-line, and have no gaps, warps or bends.
- 4) Follow the simple installation instructions provided here to insure success.
PRIVACY DUCT SILENCER
Our Privacy Duct Silencers are designed to be the best performing insertable option for privacy between rooms. At 60" long and less than 10 lbs, these silencers will significantly reduce sound transmission from both the fan motor and noise created in your home theater, studio, or kids playroom.
Many times the ducting for heat and air is overlooked as a potential flanking path, sometimes reducing the effectiveness of our soundproofing design by 15%. We now have a cost effective, simple to install, solution for just this type problem.
Privacy Duct Silencers are compatible with rigid metal ductwork (round or square), and any flexible ducting. Silencers are sized according to diameter of the existing duct. The installation is as simple as making a 60" cutout in the existing duct and inserting the silencer, taping the joints, and you are done.
Radiated Noise Reduction
- Terminal box throttling damper noise will not go
through the attenuator wall into occupied space. - Eliminates box-to-box crosstalk noise.
- To enable calculating the fan noise reduction through
or past the terminal box to downstream components. - To substitute for double-wall duct in space where difficult offsets might occur.

SEALTIGHT PUTTY PADS
Sealtight Putty Pads are designed to be applied to the external surfaces of metallic and nonmetallic electrical boxes. They are applied to the back surface of the box, as well as the three sides that are away from the stud, to combat sound bleed through the electrical box cutout in a wall.
Install Sealtight Putty Pads after the gypsum board is applied to one side of the wall and before it is closed in on the other side. Installing the Putty Pad after one side of the wall is covered with drywall requires some technique. The pad must be applied to the box and then either lapped over the front of the tile plate (if one is used) or excess material must be worked toward the front of the box and built up into a compressible gasket much like the pinched area of a pie crust. This gasket compresses between the front edge of the box and the gypsum board as it is installed.
