The AMERICAN FIBERBOARD ASSOCIATION™ (AFA) is the national trade organization of manufacturers of cellulosic fiberboard products used for residential and commercial construction, commercial products, and packaging.

AFA serves as the central clearinghouse for industry and technical information for architects, builders, contractors, distributors, dealers, government agencies, and the general public. AFA also works with government and private organizations to develop and improve industry standards and specifications and update building codes.

DEFINITION OF FIBERBOARD Fiberboard (cellulosic fiber) – structural and decorative – is a fibrous-felted, homogeneous panel made from ligno-cellulosic fibers – usually wood or cane – which has a density of less than 31 lb/ft3 (497 kg/m3), but more than 10 lb/ft3 (160 kg/m3). Fiberboard is characterized by an integral bond which is produced by interfelting the fibers, but which has not been consolidated under heat and pressure as a separate stage in manufacture. Other materials may be added to fiberboard during manufacture to improve certain properties.

Associated General Contractors of America

Located in the Metropolitan Washington, DC area, The Associated General Contractors of America (AGC) is the leading association for the construction industry. Operating in partnership with its nationwide network of Chapters, AGC provides a full range of services satisfying the needs and concerns of its members, thereby improving the quality of construction and protecting the public interest.

AGC was established in 1918 after a request by President Woodrow Wilson. Wilson recognized the construction industry's national importance and desired a partner with which the government could discuss and plan for the advancement of the nation. AGC has been fulfilling that mission for the last 90 years.

A full service national trade association with a nationwide network of exceptional chapters, AGC represents more than 33,000 leading firms in the industry - including general contractors, specialty contractors and service providers and suppliers. AGC members play a powerful role in sustaining economic growth, in addition to producing structures that add to productivity and the nation's quality of life. AGC is truly the "voice and choice" of the construction industry.

A surfacing or ballast for a roof system. Aggregate can be rock, stone, crushed stone or slag, water-worn gravel, crushed lava rock or marble chips.

The American Hardboard Association (AHA) is the national trade organization of manufacturers of hardboard products used for exterior siding, interior wall paneling, household and commercial furniture and industrial and commercial products.

AHA serves as the central clearing house on industry and technical information for architects, builders, contractors, distributors, dealers, goverment agencies and private organizations to develop and improve industry standards and specifications and to update building codes.

On February 23, 1857, 13 architects met in Richard Upjohn’s office to form what would become the American Institute of Architects. The group sought to create an architecture organization that would “promote the scientific and practical perfection of its members” and “elevate the standing of the profession.”

Asphalt produced by blowing air via molten asphalt held at an elevated temperature. This process is used to modify properties of the asphalt. The physical properties of asphalts may further be modified by 'air blowing'. This is an oxidation procedure which entails the blowing of air through the asphalts, either on a batch or a continuous basis, with the short residue at a temperature of 240°C to 320°C.

The cracking of the surfacing bitumen on a built-up roof, producing a pattern of cracks that resemble an alligator’s hide.The cracks might not extend completely through the surfacing bitumen or coating.

Alligatoring is commonly found on smooth surface asphalt roofs. It is caused by the drying out of the exposed asphalt surfacing by the sun. When the defects are tiny, it is referred to as checking.

Sheet steel having a thin aluminum coating on the surface to enhance the steel’s capability to withstand weathering. Aluminized steel is really a more recent development, becoming commercially available within the 1950's. Similar to the galvanizing procedure, aluminum is metallurgically bonded to the steel surface, providing excellent heat reflectivity and corrosion protection. Nevertheless, unlike zinc, aluminum lacks the "sacrificial protection" property discussed earlier. Consequently, scratches or exposed edges are likely to rust sooner compared to galvanized steel. For this reason, extra care is needed in the handling and installation of aluminized steel panels to steer clear of damage to the protective surface.

A non-rusting metal utilized in roofing for metal roofing and also the fabrication of gutter and flashings. Aluminum is really a option for virtually any roof where steel or other supplies are being considered. Its natural properties of light weight, strength and longevity make it a desirable roofing material. These qualities make aluminum the number 1 metal of the aerospace industry, so it only makes sense for them to be equally well-liked in the roofing business. Because aluminum roofs are lightweight, consumers can re-roof their house and reduce the weight on their housing structure. Unlike heavy tile and slate roofing, aluminum roofing does not need structural reinforcement. The other essential factor to consider is an aluminum roof's resistance to rust and corrosion over time. These unique characteristics makes aluminum roofing the preferred material in salt spray costal environments.

Ambient temperature is really a term which refers to the temperature in a room, or the temperature which surrounds an object under discussion. Ambient temperatures play a major role in personal comfort, as well as the function of many types of machines and equipment, and various methods can be utilized to control ambient temperature.

When two metals are connected in an electrolyte, they will form a galvanic cell, with the greater metal in the galvanic series being the anode. The anodic will oxidize and create an electrical present which protects the cathode from corrosion.Anodic protection is efficient in minimizing corrosion and preventing hydrogen grooving of steel. At the exact same time, the high quality of the acid is improved with respect to iron content.
