Acoustical design can be one of the most complex facets of architecture and construction. Depending on the purpose of a building or room, primary acoustical requirements could include sound control between spaces, sound control within a space, or listening efficiency in meeting rooms and auditoriums. Just as technical challenges can vary widely from space to space, so, too, do the choices of materials and design details that can meet them. Thoroughly exploring these options requires time and effort. However, this investment can yield important benefits - happier tenants, higher property values, reduced turnovers and vacancies, and greater productivity - that clients will value just as highly as they do the allure of your design.

Sound is defined as a vibration in an elastic medium, that is, any material (air, water, physical object) that returns to its normal state after being deflected by an outside force such as a sound vibration. The more elastic a substance, the better it can conduct sound. Lead, for instance, is very inelastic and therefore a poor sound conductor. Steel, on the other hand, is highly elastic, making it an excellent conductor of sound. (SA200)
Sound is transmitted in a wave motion as an elastic medium produced by a vibrating object. The vibrations move the particles of the medium (such as air) adjacent to it, back and forth, creating an alternate compression and rarefaction of the medium. These disturbances move away from the source in a wave motion, much as a ripple moves along the surface of water when a stone is dropped in.
Fire has posed a preeminent threat to human society since man first began constructing buildings and grouping them into towns and cities. To counter this threat, gypsum plaster's unique fire resistant properties have been used for centuries to protect buildings from fire. After the Great Fire of London in 1666, France's Louis XIV feared that his capital city could suffer the same fate. He issued a royal decree in 1667 ordering that all wooden buildings were to be protected with gypsum plaster. Thus, one of the earliest fire codes led to this remarkable material becoming known as plaster of Paris. The science of fire safety engineering has advanced greatly over the years to give us an in-depth understanding of the critical stages of fire initiation, growth, containment and suppression. Such knowledge has enabled today's building codes and fire protection engineers to provide fire safe structures for our homes and cities. This section presents the fundamentals of building fire protection
Moisture & Mold
You control moisture. We help control mold. When it comes to controlling mold, it can be hard to separate fact from fiction. But the bottom line is this-mold spores are everywhere, and they can grow on virtually any surface where moisture is present. Consequently, controlling mold begins with moisture control through best building practices. Adding the right protection in the right places is the other critical aspect of the equation. That's where USG BORAL can help. USG BORAL offers a full line of mold-fighting products for all areas where moisture is a concern. These products are proven to provide superior mold protection when used in conjunction with proper design and construction practices. You control moisture. We help control mold. USG BORAL products provide other desirable performance attributes like ease of use, versatility, and tile-holding strength, enabling you to create unmatched beauty-and protect the look for years to come.
Seismic compliance refers to the use of approved systems and designs that meet the seismic design requirements of a building project to provide life safety to occupants and maintain building function during and after an earthquake. Nonstructural components represent a high percentage of a project's capital investment. Failure of these components in an earthquake has the potential to cause harm, block egress and impede rescue efforts and can disrupt the building's function. The basic objectives of seismic design for nonstructural components are to provide life safety, minimize property loss and prevent functional loss.
