Direct applied systems do not incorporate the use of rigid board insulation and are not within the scope of this book. Also polymer — based, the synthetic stucco is applied to a variety of water-durable substrates such as concrete masonry units and concrete. There are two fundamental wall construction concepts of EIFS that will be […]

Exterior insulation and finish systems (EIFS) are multilayered exterior wall systems that are used in both commercial and resi­dential construction. Sometimes referred to as synthetic stucco, the basic five primary components include a rigid insulation board, an adhesive to attach the insulation board to a suitable substrate, a reinforcing mesh that is embedded in a […]

Compressed-straw panels are not new. The process for producing compressed agricultural fiber (CAF) panels was invented in Sweden in 1935 by Theodor Dieden and later developed into a commercial product in Britain under the name Stramit by Torsten Mossesson in the late 1940s. Although the original patents have expired on the technology for producing compressed […]

Contoured foam underlayment (CFU) is a drop-in rigid foam insu­lation product that is custom made to fit snugly behind different styles of vinyl siding. This new product is intended to improve the rigidity of vinyl siding as well as its resistance to denting and warping. CFU typically is made from XPS foam that provides an […]

Composite board insulation is usually is made of two different insu­lation materials that are laminated together. Mainly used for low — slope roofing, a typical example of a composite board is PIR or EPS combined with perlite or wood fiberboard. Composites also can incorporate insulation with other roofing materials, such as PIR laminated to a […]

Cellular glass insulation is a rigid roof insulation board composed of heat-fused, closed glass cells blown with hydrogen sulfide. Available for low-slope roofing systems, the boards typically have kraft paper facers applied to the surfaces after the material is formed. Cellular glass is compatible with bitumen and other adhe­sives and is fire-resistant. The board itself […]

Based on research conducted for this book, the phenolic foam insu­lation board industry in both Canada and the United States declined rapidly and essentially disappeared in 1993-1994. Incidents of deck corrosion have been reported in cases where the insulation is in direct contact with steel roof decks and moisture is present.11 Phenolic foam board products […]

Although the term mineral fiber historically refers to rock wool and slag wool, fiberglass products are also included in this cate­gory. These are also called man-made vitreous fibers (MMVFs), referring to the glassy, noncrystalline nature of these materials. A binding agent helps form the fibers into a rigid insulation board to be used for low-slope […]

Fiberboard, historically called structural insulating board, is made primarily from wood, cane, or other organic fibers combined with a variety of binders.10 Fiberboard was popular during the two decades after World War II. During manufacture, the raw material is reduced to a pulp, and then the fibers are chemically treated with waterproofing materials. Some boards […]

As discussed in Chap. 7, perlite is a granular-type insulation made from a naturally occurring silicous rock quarried mainly in the western United States. Perlite is different from other volcanic glasses because when the crushed ore is heated to a suitable point in its softening range, it expands from 4 to 20 times its original […]
