GypSorb Frequently Asked Questions

Adding perforations to GypSorb perforated acoustic gypsum board allows sound waves to enter into the holes to be absorbed rather than bounced back into the room. GypSorb perforated acoustic gypsum boards also have a special fleece on the back side of each panel that also absorbs sound. To further enhance the absorption performance, add an additional sound absorbing material behind the panel such as a fiberglass, mineral wool, cotton, or PolySorb polyester paneling.

GypSorb perforated acoustic gypsum boards are used in interior environments to control sound reverberation, lower ambient noise levels, and improve speech intelligibility. GypSorb perforated acoustic gypsum board can be used on ceilings and walls. GypSorb perforated acoustic gypsum boards are also very popular decorative and functional materials used in restaurants, classrooms, airports, lobbies, offices, meeting rooms, lecture halls, common areas, recreation facilities or any other space requiring acoustical conditioning.

GypSorb perforated acoustic gypsum boards can be installed directly to available framing, suspended drywall grid systems, overhead ceiling joists, wall studs, etc. If installing on a flat surface, furring or metal hat channel should be used to space the panel off the mounting surface. To perform acoustically at its best, there should be small air space behind the boards. Joints between each panel should be treated with a manufacturer specified tape and then screw holes filled with manufacturer specified filler. After joint and screw holes are finished, the boards can be roller painted.

GypSorb perforated acoustic gypsum boards should ONLY be painted with a roller. Spray painting should be avoided as it will coat the perforation’s cellular construction and greatly reduce the sound absorbing capabilities.

No. GypSorb perforated acoustic gypsum board is designed to absorb sound, not to block sound. Because the material is perforated with thousands of holes, it prevents sound from transmitting through the material and bouncing back into the room space.

GypSorb perforated acoustic gypsum boards are specially made from ordinary gypsum board but with thousands of uniform holes punched through the surface. These hole designs make GypSorb perforated acoustic gypsum board perform with excellent sound absorption and insulation qualities, so it can widely be used in environments where the acoustics needs to be controlled, such as concert halls, hoe and commercial theaters, recording and television studios, large and small conference rooms, multi-purpose community halls, as well as offices and residential spaces where noise pollution needs to be mitigated.
The size and pattern of the perforation holes in GypSorb perforated acoustic gypsum boards play a direct and testified impact on sound absorption and sound insulation. The larger the hole and the more of them there are, the more capable the sound absorption effect of the board will be, because more sound waves can enter the holes and be soaked up inside the board, consuming energy instead of releasing it back into the space. At the same time, too large of holes will cause the strength and stability of the board to weaken. In that, when we engineer our GypSorb perforated acoustic gypsum boards, it is necessary to strategically determine the size and distribution of holes according for the specific environment and acoustic requirements the customer desires.

1. The production process and characteristics of paper faced gypsum board

Standard paper faced gypsum board, also known as drywall, is made from gypsum as the primary raw material, binding additives, and covered with heavy paper on the front surface. The main feature is continuity, excellent surface flatness, suitable for indoor walls, ceilings and other specialty locations. The production process is simple keeping the price relatively low. It is one of the most commonly used construction materials. Paper faced gypsum board has several types: normal horizontal surface, shower surround with higher cement content and green paper surface for better moisture resistance in high moisture areas.

2. The production process and characteristics of GypSorb perforated acoustic gypsum board 

GypSorb perforated acoustic gypsum board are essentially made of the same raw materials as standard paper faced drywall, but the surface is perforated during the production process. There are many variations of holes and patterns on the surface of GypSorb perforated acoustic gypsum boards, which not increases the dramatic beauty, but also plays a role in sound and noise attenuation. Because of additional development, production and handling costs, the price of perforated gypsum boards is slightly higher, but becoming more widely used in concert halls, cinemas, multi-purpose halls, arenas, commercial spaces and other places where noise control needs to be considered.

3. The difference in the applicable uses of the two types of gypsum boards

Paper faced gypsum boards are suitable for homes, offices, schools and other places where final wall coverings require it. Because of their lower production costs and consistently smooth surfaces, and that they can be easily installed, finished and painted, they are more widely used. Perforated gypsum boards are suitable for the aforementioned places and those with higher noise control requirements, such as cinemas, concert halls, recording studios, etc. The perforations, small holes, on the surface of gypsum boards can effectively absorb noise and provide high-quality sound attenuation as well as adding visual drama to any space.

GypSorb perforated acoustic gypsum board is engineered to absorb sound more effectively due to their porous hole structure and specific patterns developed for specific sound waves. This makes them ideal for environments where noise reduction is important. They can be used in conjunction with our sister company PolySorb PET panels.

Facts and Considerations
Gypsum is a naturally occurring, crystalline mineral mined from the earth. For the most part, it is entirely harmless to living beings. There are risks associated with the inhalation of gypsum dust during the cutting and installation process. This is a risk that is faced by those who mine gypsum raw materials, but not by construction workers who install gypsum products, or people who spend even a considerable length of time in the finished structures. Gypsum dust contains silica, which is known to affect the respiratory and neurological systems, but the manufacturing process encapsulates it and painting the panel surface further seals it in.

Understanding the Risks
Gypsum is considered safe for landfills and other waste disposal methods. It is also recyclable and should be taken to a recycling facility in your area. Concerns have been raised about the radioactive isotopes sometimes found in gypsum – namely radium-226 and thorium-228. These are only found in trace amounts which do not pose any risk to living beings. The levels of these isotopes have been found to be well below hazardous levels.

Insights and Applications
Gypsum board is highly heat resistant by nature. Its chemical composition includes bounded water. When exposed to high temperatures, these water molecules are released as steam and slow down heat transfer, reduce flashing and act as a natural fire resistance barrier. This is why gypsum drywall is wisely used for fire rated construction projects.

The fire resistant properties of gypsum drywall is among its most important benefits and it is non-combustible and flame retardant by nature, making it a vital component and safety feature for construction of homes and commercial buildings. GypSorb perforated acoustic gypsum board can have a fire-resistance rating of between one to four hours, depending on the exact composition of the product used. That means that a gypsum covered walls and ceilings can withstand open flame for anywhere between one and four hours.
