The StarSilent System

Pyrok, Inc. a leading manufacturer of sound absorbing plaster and cement finishes introduces Pyrok StarSilent.

The StarSilent system is a smooth, seamless, sound absorbing, durable plaster finish system for walls and ceilings.

The StarSilent panel is a sound absorbing panel that is made up of post-consumer, recycled, crushed glass bottles and coated with sound permeable plasters.

This environmentally friendly product allows designers to utilize a seamless, gypsum board look with sound absorbing qualities. It is utilized in many configurations where gypsum board is typically utilized, and can be used on curved surfaces of any radius, as well as on compound curves.

The StarSilent system utilizes a sound panel that is composed of up to 96% post-consumer, recycled crushed glass bottles. The plasters are composed of 50% recycled marble aggregate. The panels are attached to rigid metal framing with zinc coated drywall screws. The edges of the panels are glued together using a special adhesive, which is also spread over the screw heads. After light sanding, the panels are first coated with a base coat plaster that requires a minimum of 36 hours to dry. The finish coat plaster is then applied to achieve a smooth, seamless, sound absorbing plaster wall or ceiling.

The StarSilent smooth finish plaster and superfine sprayed plaster can be tinted to a wide range of colors. The plasters can also be painted per Pyrok Inc. painting instructions.

Advantages

No gypsum board substrate is required. If there is ever water infiltration from above the StarSilent System, the only damage will be to the StarSilent finish plaster. Systems using a gypsum board substrate will have to remove the entire system as well as all the damaged gypsum board.
The structural integrity of the system is not compromised by the lack of gypsum board in the assembly.
It can be used on contact walls. We recommend that stud spacing on walls below a height of 6 feet be 8 inches on center. The recycled glass StarSilent panels provide a sturdy surface resistant to modest damage.
The StarSilent plasters are spread over the rigid StarSilent panel. The levelness of the finish is superior to other systems, where the plasters are troweled over resilient fiberglass panels.
It can be painted without loss of its sound absorbing quality. The paint must be spray applied in 2 light coats from a distance of 24 inches. Painting must be done with light coats, as excessive painting can highlight micro textures in plaster finish. Acoustic data and painting instructions are available from Pyrok, Inc.
It has extremely low VOC content (almost zero) and the highest percentage of recycled content of any smooth, seamless, acoustic plaster system.
It can be integrated with a radiant heating and cooling system.
It is the most installer friendly of any smooth, seamless, acoustic plaster system.
Highest compressive strength of any smooth acoustic plaster system. Higher compressive strength means higher durability.
Easiest system to patch and repair. If required, Pyrok, Inc. will send an experienced technician to the project to assist or accomplish difficult repairs.
As the product is detailed in a similar manner as gypsum boards for trimless lights, trimless diffusers, and access panels, the architectural details are simpler and the field execution superior.
StarSilent has the thinnest assembly thickness of any acoustic plaster system. A benefit of this is the ease of mounting artwork or accessories through it on ceilings and wall applications.
Less cost and quicker install time than other systems, as gypsum board is not required, and drying times for the plasters are very short.
Pyrok, Inc. is present on site to assist its installers with their installations. Pyrok, Inc. offers a 5-year warranty.

Components

Galvanized steel suspended ceiling grid
Other types of framing systems are also used with the StarSilent System
StarSilent Panel
Zinc coated drywall screws
Acoustically transparent base coat plaster
Acoustically transparent smooth plaster finish
Not Shown: rigid vertical framing

StarSilent Panel
The panel thicknesses are 10mm, 15mm and 25mm. Contact Pyrok, Inc. for panel sizes.

StarSilent Cool
The StarSilent panel incorporates room cooling and heating.

StarSilent Fix
The StarSilent Fix adhesive is used to glue the edges of the StarSilent panels together, and to spread over the screw heads that fasten the panels to the framing. The Fix is also used to embed edge trims, corner trims, reveal trims, and some ceiling accessories.

StarSilent Base Coat Plaster
This is the first coat of plaster that is hand applied over the StarSilent panels. It is slightly coarser than the StarSilent Finish plaster. A second layer of Base Coat plaster can be left as the finish, if this level of finish is desired.

StarSilent Finish Plaster
The StarSilent Finish plaster is hand applied to a smooth finish. Specify StarSilent “smooth” when a gypsum board look is desired.

StarSilent Plan
The StarSilent Plan is used for the StarSilent Superfine system, which is spray applied. The Plan is used to mud the screw heads, and a light coat is applied over the StarSilent Fix on the panel joints.

StarSilent Superfine Plaster
This plaster is spray applied to a light superfine texture that when applied at heights above 18 feet appears smooth. When this finish is desired, specify StarSilent “superfine”.

Edge Beads/Trims
Contact Pyrok, Inc. for recommended edge beads and trims.

Framing

Types of Framing Systems
The StarSilent system utilizes the following framing systems:
• 1 1/2 inches cold rolled channel with 7/8 inch hat channel.
• A T-bar grid system, preferably an exterior stucco/plaster T-bar grid system.
• Metal stud or wood framing

It is preferable to frame for the StarSilent panels on 15 3/4 inch centers for ceilings and walls above 6 feet and 7 7/8 inch centers for walls below 6 feet. This is due to the metric sizing of the StarSilent panels. Framing at 16 inch centers is also easily handled with the StarSilent panels.

The vertical suspension for the above framing systems should be rigid, and sometimes will require bracing or kickers.

Acoustical

Acoustical Performance
The StarSilent system has two finishes, smooth and superfine. The StarSilent panels come in 10mm, 15mm and 25mm thicknesses. The NRC values range from 0.55 to 0.90. Contact Pyrok, Inc. for NRC data, octave band sound absorption coefficients, and laboratory conducted acoustical test reports.

Installation

Follow the instructions when installing the StarSilent panelling. Applicators have the responsibility to provide professional workmanship and quality. Training or instruction prior to beginning application is recommended. The Panels are to be stored indoors on an even surface. They are to be protected from damp and weathering influences and are to be stored in the appropriate installation conditions for at least 1 day prior to installation.

The StarSilent Panels may only be installed after establishing the appropriate equilibrium humidity and temperature in the room. Sudden heating or cooling during the installation and drying period may lead to cracking. Special design details and the latest documentation are available from sales representatives of Pyrok Inc. The ceiling is not 100 % glancing light-free.

Details

The Pyrok StarSilent System is detailed in a similar way to gypsum board. The use of L beads, corner beads, control joints and reveals are used to create details that are commonly used or details that are specific to one’s project.

In all cases, it is important that the StarSilent ceiling framing is not mechanically fastened to the wall to prevent cracking in the acoustic plaster due to building settlement and movement in walls and ceilings.

Installing a slight perimeter gap between the ceiling and wall also allows for pressure equalization when a ceiling plenum is used for return air.
