10、>  How EIFS is installed</p><p>  EIFS is typically attached to the outside face of exterior walls with an adhesive (cementitious or acrylic based) or mechanical fasteners. Adhesives are commonly used to

11、attach EIFS to gypsum board, cement board, or concrete substrates. EIFS is attached with mechanical fasteners (specially designed for this application) when installed over sheet-good weather barriers such as are commonly

12、 used over wood sheathings. The supporting wall surface should be continuous (not "open framing") and flat.</p><p>  Composition and types of EIFS</p><p>  EIFS consists of a number of

13、 layers that are installed in the following order. The most basic EIFS (a barrier EIFS) consists of 3 layers:</p><p>  A layer of foam plastic insulation (also called simply "foam") that comes in t

14、he form of sheets . If an adhesive is used to attach the insulation, the adhesive is applied to the foam with a trowel. Most EIFS use a type of insulation called Expanded Polystyrene, also known as EPS. EPS is 1 lb.

16、lt;p>  A reinforced layer that is applied onto the face of the insulation with a trowel, consisting of a fiberglass reinforcing mesh ( or "mesh") embedded in a cementitous adhesive. The mesh has an open weav

17、e, somewhat like window screening but with opening about 1/4" square. It is made of fiberglass and can be cut with a utility knife. The mesh is available in various weights, the "heaviness" determines the

18、impact strength of the surface (resistance to damage by being "hit"). The standard weight is 4o</p><p>  A final topcoat,or finish, which is a colored, textured paint-like material that is applied

19、with a trowel or, very rarely, by spraying. A wide range of colors and textures are available as well as custom colors. Available textures include smooth surfaces, rough "stucco-like" textures, embedded stone c

20、hips, multi-color (granite-like mixtures,) and even brick-like treatments. This layer is called the finish. It is acquired by floating. </p><p>  If an EIFS with Drainage, or water-managed EIFS is installed,

21、 a water resistive barrier (aka a WRB) is first installed over the substrate (generally DensGlas Gold, exterior-grade gypsum sheathing, OSB or plywood). The moisture barrier is applied to the entire wall surface with a m

23、lt;/p><p>  Adhesives and Finishes are water-based, and thus must be installed at temperatures well above freezing. Two types of Adhesives are used with EIFS: those that contain Portland Cement ("cementiti

24、ous"), or do not have any Portland Cement ("cementless"). Adhesives that contain Portland Cement harden by the chemical reaction of the cement with water. Adhesives and Finishes that are cementless harden

25、by the evaporation of water - like house paint. Adhesives come in two forms. The most common is in a p</p><p>  History of EIFS</p><p>  EIFS was developed in Europe after World War II and was i

28、ther ar</p><p>  In North America, EIFS was initially used almost exclusively on commercial buildings. As the market grew, prices dropped to the point where its use became widespread on normal single family

29、homes.</p><p>  In the late 1980s problems started developing due to water leakage in EIFS-clad homes. This created a national controversy and numerous lawsuits. While not inherently more prone to water pene

30、tration than other exterior finishes, critics argue that barrier-type EIFS systems (non-water-managed systems) do not allow water that may penetrate the building envelope to escape.[ </p><p>  The EIFS indus

31、try has consistently maintained that the EIFS itself was not leaking, but rather poor craftsmanship and bad architectural detailing at the perimeter of the EIFS was what was causing the problems. The building codes react

32、ed by mandating EIFS with Drainage on wood frame building and additional on-site inspection. Most homeowner insurance policies cover EIFS and EIFS-like systems.</p><p>  Insurance companies like FM Global ma

33、y not provide fire insurance coverage to clients who install EIFS exterior building systems, due to the lack of adequate fire-resistance inherent in the materials. Also, some facility owners have found that EIFS systems

34、that are installed at lower building levels are subject to vandalism as the material is soft and can be chipped or carved resulting in significant damage.</p><p>  Legal issues</p><p>  EIFS sys

35、tems have been the subject of several lawsuits, 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 Ma

36、rtin, California courthouse. This case was settled for 12 million dollars. </p><p>  The basic underlying problem behind EIFS litigation was that EIFS was marketed as a cost-effective replacement for stucco.

37、 Stucco is expensive to install because it cracks over time. Stucco must be carefully applied by skilled craftsmen so that the cracks which will inevitably develop are subtle and not obvious. General contractors switched

38、 to EIFS because it was supposed to be easy to install with unskilled or semi-skilled labor and would not crack like traditional stucco. Although EIFS if prop</p><p><b>  外墻外保溫系統(tǒng)</b></p>&
