Innovative solution for sound control

Dramatically reduce the sound you hear between rooms

Turn down the volume when you incorporate SoundBreak® XP® drywall into your walls and ceilings Perfect for new construction projects, this superior sound-damping drywall will dramatically reduce noise transmission between rooms or dwelling units.

SoundBreak XP combines exceptional performance with smart solutions that go beyond standard drywall and is moisture-, mold- and mildew resistant. It is ideal for bedrooms, nurseries, home offices, media rooms, ceilings and anywhere else it’s important to keep noise contained.

SoundBreak XP is available in 1/2", 5/8” and 3/4" thicknesses.

Sound Control

  • Superior sound damping, cost-efficient material that finishes easily and decorates in the same manner as standard gypsum board.
  • Provides high-rated Sound Transmission Class (STC) values reducing sound between walls per an independent third-party acoustical laboratory (ASTM E90).
  • 3/4” provides high-rated Impact Insulation Class (IIC) values reducing sound in floor ceiling assemblies per an independent third-party acoustical laboratory (ASTM E492).
  • Thinner than traditionally built high-STC walls, increasing usable floor space.

Installs Fast And Easy

  • Installs like traditional gypsum board, without requiring additional clips and/or channels.
  • Finishes and decorates as easily as standard gypsum board.
  • Features GridMarX® guide marks on the board to allow for faster and more accurate installation.
  • For speed of installation and lower installation costs, vertical board joints do not require acoustical sealant.
  • Provides greater resistance to surface abrasion and indentation than standard gypsum board (ASTM C1629).
  • Should be used according to specifications to achieve the highest possible sound ratings.

Inhibits Mold Growth

  • Helps inhibit mold growth with the highest possible score on mold tests (ASTM D3273 and ASTM G21).
  • Features SPORGARD® technology with extra mold-inhibiting properties.

Resists Moisture Better

  • Fights the effects of moisture before damage can occur.
  • Helps to reinforce the structure’s integrity and strength.
  • Reduces dimensional movement caused by moisture.

Provides Fire Resistance

  • 5/8” and 3/4” features a fire-resistant core that is more fire resistant than ordinary drywall
  • 5/8” and 3/4” are approved components in UL fire-rated designs.
  • UL Classified for fire resistance and surface burning characteristics.

Frequently Asked Questions

How do SoundBreak® XP® Drywall products reduce sound travel between rooms?

While there’s no such thing as completely soundproof drywall, by installing SoundBreak® XP® or adding SoundBreak XP Retrofit® to existing drywall you can drastically reduce the amount of noise you hear between rooms from music, television, conversation, a baby crying or dogs barking.

At the center of SoundBreak XP® drywall products is a layer of material specifically designed to absorb and dissipate noise. That material, called a polymer, is sandwiched between two pieces of high-density, mold-resistant drywall and covered by heavy, moisture-, mold- and mildew-resistant, 100 percent recycled purple paper on both sides.

Isn’t all drywall the same?

No. While all drywall is naturally fire-resistant, PURPLE drywall is unique because it also resists moisture, mold and mildew. Some PURPLE drywall products also stand up to scratches, scuffs, dents and sound. This means added value and peace of mind regardless of steamy showers, roughhousing kids or band practice. All PURPLE products have achieved GREENGUARD Gold Certification for indoor air quality and are as easy to install and finish as standard drywall.

What’s the difference between PURPLE drywall and traditional green drywall?

Traditional green drywall (also known as greenboard) is only moisture-resistant. PURPLE drywall, manufactured only by Gold Bond Building Products, is superior because it offers moisture, mold and mildew resistance. In addition, many PURPLE drywall products offer added benefits, including resistance to scratches, scuffs, dents and noise.

What makes PURPLE drywall resistant to moisture, mold and mildew?

PURPLE drywall is made of a specially treated, moisture- and fire-resistant gypsum core. That core is sandwiched between heavy, moisture-, mold- and mildew-resistant, 100 percent recycled paper that’s purple on the front and gray on the back.

What makes PURPLE drywall naturally fire-resistant?

Gypsum itself is naturally fire-resistant. Gypsum drywall is made by sandwiching a core of wet plaster between two sheets of paper. When the core sets and dries, the gypsum board becomes a strong, rigid, fire-resistant building material. It’s resistant to fire because in its natural state, gypsum contains water; and when exposed to heat or flame, this water is released as steam, which delays heat transfer.

How do I know how much drywall I need?

Use our Materials Calculator to determine how much drywall you’ll need for your next project. All you need to know are your room’s dimensions. The calculator will do the rest. You can also get in-person help at your local home improvement store or ask your contractor.
