64-521: A fault-tolerant design ). EIFS account for about 10% of the US commercial wall cladding market. There are several dozen EIFS manufacturers in North America. Some sell nationwide, and some are regional in their area of business operations. The top five EIFS producers account for about 90% of the US market. These producers include Dryvit Systems, STO Corp., BASF Wall Systems, Master Wall, and Parex. EIFS offer

96-822: A part of the EIFS scope of work. Many of the EIFS manufacturers have their own standard details showing typical building conditions for window and door flashings, control joints, inside/outside corners, penetrations, and joints at dissimilar materials which should be followed for that manufacturer's warranty. EIFS are typically attached to the outside face of exterior walls with an adhesive (cementitious or acrylic based) or mechanical fasteners. Adhesives are commonly used to attach EIFS to gypsum board, cement board, or concrete substrates. EIFS are attached with mechanical fasteners (specially designed for this application) when installed over house wraps (sheet-good weather barriers) such as are commonly used over wood sheathings. Research, conducted by

128-431: A result. While the EIFS industry has consistently tried to shift the blame to installing contractors, the construction industry has retorted that using journeymen carpenters in turn eliminates the cost advantage of EIFS over stucco, and that the EIFS industry should have anticipated this issue and engineered its products from the beginning to be installed by unskilled labor or semi-skilled labor (that is, it should have been

160-455: A safe route back to the outside. The purpose is to preclude water from damaging the supporting wall. Adhesives and finishes are water-based, and thus must be installed at temperatures well above freezing. Two types of adhesives used contain Portland cement ("cementitious"), or do not have any Portland cement ("cementless"). Adhesives that contain Portland cement harden by the chemical reaction of

192-479: A substantial waiting-list of producers seeking organizational memberships on the more popular committees. Members can participate without a formal vote and their input will be fully considered. As of 2015, ASTM has more than 30,000 members, including over 1,150 organizational members, from more than 140 countries. The members serve on one or more of 140+ ASTM Technical Committees. ASTM International has several awards for contributions to standards authorship, including

224-627: A textured protective finish coat. The predominant method of EIFS applied today is EIFS with Drainage , which provides a way for moisture accumulated in the wall cavity to evacuate. EIFS is not stucco despite often called "synthetic stucco". Traditional stucco is a centuries-old, hard, dense, thick, non-insulating material which consists of aggregate, a binder, and water. EIFS is a lightweight synthetic wall cladding that includes foam plastic insulation and thin synthetic coatings. There are also specialty stuccos that use synthetic materials but no insulation, and these are also not EIFS . A common example

256-592: A wide range of materials, products, systems and services. Some 12,575 apply globally. The headquarters is in West Conshohocken, Pennsylvania , about 5 mi (8.0 km) northwest of Philadelphia . It was founded in 1902 as the American Section of the International Association for Testing Materials. In 1898, a group of scientists and engineers , led by Charles Dudley , formed ASTM to address

288-743: Is one-coat stucco , which is a thick, synthetic stucco applied in a single layer (traditional stucco is applied in 3 layers). EIFS are proprietary systems of a particular EIFS manufacturer and consist of specific components. EIFS are not generic products made from common separate materials. The materials and installation methods specified by different EIFS manufacturers are not all compatible and should not be used interchangeably in new construction or repair work. The technical definition of an EIFS does not include wall framing, sheathing, flashings , caulking , water barriers, windows, doors, and other wall components. However, some architects have begun specifying flashings, sealants , and wiring fasteners as being

320-567: Is voluntary and is initiated by the member's request, not by appointment or invitation. Members are classified as users, producers, consumers, and "general interest". The latter includes academics and consultants. Users include industry users, who may be producers in the context of other technical commodities, and end-users such as consumers. To meet the requirements of antitrust laws, producers must constitute less than 50% of every committee or subcommittee, and votes are limited to one per producer company. Because of these restrictions, there can be

352-408: Is applied to the entire wall surface with a mesh tape over joints and a liquid-applied membrane or a protective wrap like tyvek or felt paper . Then a drainage cavity is created and the other 3 layers, described above, are added. This type of EIFS is required by many building codes areas on wood-frame construction and is intended to provide a path for incidental water that may get behind the EIFS with

384-431: Is the system that includes a drainage cavity, which allows any and all moisture to exit the wall. EIFS with drainage typically consists of the following components: If an EIFS with Drainage, or water-managed EIFS is installed, a water resistive barrier (aka a WRB) is first installed over the substrate (generally glass faced exterior-grade gypsum sheathing , oriented strand board (OSB) or plywood ). The moisture barrier

416-830: The ASTM International Award of Merit (the organization's highest award) ASTM International is classified by the United States Internal Revenue Service as a 501(c)(3) nonprofit organization. ASTM International has no role in requiring or enforcing compliance with its standards. The standards may become mandatory when referenced by an external contract, corporation, or government. In the United States, ASTM standards have been adopted, by incorporation or by reference, in many federal, state, and municipal government regulations. The National Technology Transfer and Advancement Act , passed in 1995, requires

448-422: The 2008 Monte Carlo Hotel Casino fire. Types of EIFS are defined by their materials and the existence/absence of a drainage plane. The EIFS Industry Members Association (EIMA) defines two classes of EIFS: Class PB (polymer based) identified as PB EIFS, and Class PM (polymer modified) identified as PM EIFS. PB EIFS is the most common type in North America. It uses expanded polystyrene (EPS) insulation adhered to

480-602: The EIFS itself was the weather barrier. After 2000, the EIFS industry introduced the air/moisture barrier that resides behind the foam. In a study done by the Department Of Energy's Office of Science - Oak Ridge National Laboratory, it was found that the best air/moisture barrier was a fluid barrier. The Oak Ridge National Laboratory, ATLANTA, Oct. 28, 2006 — EIFS "outperformed all other walls in terms of moisture while maintaining superior thermal performance." The National Institute of Standards and Technology (NIST) has evaluated

512-588: The Oak Ridge National Laboratory and supported by the Department of Energy, has affirmed that EIFS are the "best performing cladding" in relation to thermal and moisture control when compared to brick, stucco, and cementitious fiberboard siding. EIFS are in compliance with modern building codes that emphasize energy conservation through the use of CI (continuous insulation) and a continuous air barrier. EIFS before 2000 were barrier systems, meaning that

544-504: The building to escape. The EIFS industry has consistently maintained that poor craftsmanship and bad architectural detailing at the perimeter of the EIFS was the problem. As a result, building codes began mandating a drainage system for EIFS systems on wood-frame buildings and additional on-site inspection . Though there are some cases where insurance companies may not offer coverage for EIFS, several companies do. EIFS systems installed at lower building levels are subject to vandalism , as

576-434: The cement with water. Adhesives and finishes that are cementless harden by the evaporation of water. Adhesives come in two forms: The most common is in a plastic pail as a paste, to which Portland cement is added and as dry powders in sacks, to which water is added. Finishes come in a plastic pail, ready to use, like paint . EIFS insulation comes in individual pieces, usually 2' x 4', in large bags. The pieces are trimmed to fit

608-475: The federal government to use privately developed consensus standards whenever possible. The Act reflects what had long been recommended as best practice within the federal government. Other governments have also referenced ASTM standards. Corporations doing international business may choose to reference an ASTM standard. All toys sold in the United States must meet the safety requirements of ASTM F963, Standard Consumer Safety Specification for Toy Safety, as part of

640-619: The five life cycle stages of the environmental impact of EIFS alongside brick, aluminum, stucco, vinyl, and cedar. Depending on a variety of site and project specific conditions, EIFS have the potential to save money in construction costs and contribute toward energy efficient operations and environmental responsibility when correctly designed and executed. Some types of EIFS have passed some fire tests that range from resistance to ignitability, that include: ASTM E 119, NFPA 268, NFPA 285. However, some types and thicknesses of EIFS have been involved in large uncontrolled exterior building fires, such as

672-411: The frequent rail breaks affecting the fast-growing railroad industry. The group developed a standard for the steel used to fabricate rails. In 1961, originally called the "American Society for Testing Materials" it was changed to "American Society for Testing And Materials". In 2001, ASTM officially changed its name to "ASTM International" and added the tagline "Standards Worldwide". In 2014,

736-702: The late 1980s problems started developing due to water leakage in EIFS-clad buildings. This led to international controversy and lawsuits. EIFS installation was found to be a contributing factor in the multibillion-dollar problem known as the " Leaky condo crisis " in southwestern British Columbia and the " Leaky homes " issue in New Zealand that emerged separately in the 1980s and 1990s. Critics argue that, while not inherently more prone to water penetration than other exterior finishes, barrier-type EIFS systems (non-water-managed systems) do not allow water that does penetrate

768-587: The material is soft and can be chipped or carved resulting in significant damage. In these cases, heavier ounce reinforcing mesh can drastically increase the durability of the EIFS system. EIFS is now used all over North America, and in other areas around the world, especially in Europe and the Pacific Rim . The use of EIFS over stud -and-sheathing framing instead of over solid walls is a technique used primarily in North America. As of 1997 EIFS accounted for about 4% of

800-491: The option of adding architectural details that are composed of the same materials. These mouldings come in a variety of shapes and sizes. They are widely used on residential and commercial projects in North America and are gaining popularity worldwide.

832-534: The residential siding market and 12% of the commercial siding market. In the United States , the International Building Code and ASTM International define Exterior Insulation and Finish System (EIFS) as a non-load-bearing exterior wall cladding system that consists of an insulation board attached either adhesively, mechanically, or both, to the substrate; an integrally reinforced base coat; and

864-572: The substrate with fiberglass mesh embedded in a nominal 1 ⁄ 16 inch (1.6 mm) base coat which can receive additional layers of mesh for stronger impact resistance. Other types of insulation board can include polyisocyanurate . PM EIFS use extruded polystyrene insulation (XEPS) and a thick, cementitious base coat applied over mechanically attached glass fiber reinforcing mesh. The system has joints similar to traditional stucco. PM EIFS have evolved to include different insulation materials and base coats. The most common type of EIFS used today

896-544: The tagline changed to "Helping our World Work better." Now, ASTM International has offices in Belgium, Canada, China, Peru, Washington, D.C., and West Conshohocken, PA. In April of 2016, the Safety Equipment Institute (SEI) became a subsidiary of ASTM International. SEI is an accredited third-party certification organization that certifies various types of PPE to industry consensus standards. On June 9, 2022, it

928-410: The wall at the construction site. EIFS systems have been the subject of several lawsuits in the United States, mostly related to the installation process and failure of the system causing moisture buildups and subsequent mold growth. The most notable case concerned the former San Martin, California courthouse. This case was settled for $ 12 million. The basic underlying problem behind EIFS litigation

960-459: Was announced that the European Committee for Standardization (CEN) and ASTM International agreed to extend and expand a Technical Cooperation Agreement from 2019. Membership in the organization is open to anyone interested in its activities. Standards are developed within committees, and new committees are formed as needed, upon request of interested members. Membership in most committees

992-494: Was first used on masonry buildings. Since the 1990s, the majority of wood-framed buildings have used EIFS. EIFS was developed in Europe after World War II and was initially used to retrofit masonry walls. EIFS started to be used in North America in the 1960s, at first on commercial masonry buildings. EIFS became popular in the mid-1970s due to the oil embargo and the resultant surge in interest in insulating wall systems that conserve energy used for heating and cooling. In

1024-676: Was that EIFS was marketed as a cost-effective replacement for stucco. Stucco is expensive to install because it must be carefully applied by skilled craftsmen. General contractors switched to EIFS because they were supposed to be easy to install with unskilled or semi-skilled labor and would not crack like traditional stucco. Although EIFS if properly installed according to the manufacturer's directions should not have water intrusion problems, many installers cut corners by using insufficiently trained labor and also failed to supervise their work adequately. In turn, thousands of EIFS installations were noncompliant and suffered severe water intrusion and mold as
