SilentFX Noise-Reducing Gypsum Board. The best in acoustic management.

SilentFX®, featuring Green Glue® and M2Tech® technology, is a noise-reducing gypsum board specifically designed for systems requiring high STC ratings where acoustic management is needed.
Green Glue, applied between two specially formulated gypsum boards, is a viscoelastic polymer that dampens sound energy and significantly improves sound attenuation through walls and ceilings.
SilentFX gypsum board is enclosed in a 100% recycled moisture and mold resistant face and back paper. As a result of the inclusion of M2Tech technology, SilentFX also contributes to indoor air quality by providing enhanced moisture and mold resistance.
SilentFX® Gypsum Boards are intended for use on interior walls and ceilings in residential, commercial or institutional applications. They can be used for new construction or renovations over wood or steel framing. It is typically nailed or screwed to studs spaced 16" or 24" o.c.

SilentFX® Gypsum Board is installed following traditional methods of application and finishing of interior gypsum board products for both walls and ceilings.
• Plan SilentFX board layout to stagger joints from one side of the wall to the other.
• Install insulating batts (CertainTeed’s thermal and acoustical fiber glass insulation or equivalent) in cavities.
• Use putty pads (tested per ASTM E 90) or acoustical sealant to seal electrical outlets.
• Install SilentFX in accordance with GA-216, “Application and Finishing of Gypsum
Panels” (ASTM C840).
• Allow a 1/4" (6 mm) gap around all wall perimeter edges.
• SilentFX boards are cut by deeply scoring from both sides and snapping, or using a hand or power saw.
• Cutting across 4' (1220 mm) width may require use of a hand or power saw.
• Seal the 1/4" (6 mm) perimeter gaps and wall penetrations per ASTM C 919 with acoustical sealant (Green Glue® Noiseproofing Sealant or equivalent).


SilentFX Gypsum Board may be finished, painted or wallpapered using conventional gypsum board techniques. The Gypsum Association publication GA-214, “Recommended Levels of Gypsum Board Finish,” should be referenced when specifying the level of finishing desired.

CertainTeed is committed to resource conservation:

The face and back paper used for our gypsum board consists of 100% recycled paper.
Synthetic or “by-product” or DSG gypsum produced from the desulphurization of flue gases at coal-fired power plants is used where sources
are available. The total recycled content for these synthetic gypsum plants is 96%.
In-plant scrap is recycled back into the process.; Our 13 gypsum board manufacturing locations provide regional material coverage throughout North America.
