About Vinyl Siding

Vinyl siding was first used in the exterior cladding market in the early 1960s and grew increasingly in popularity over the next four decades because of its sturdiness, versatility, and ease of up keep. Vinyl Siding is made primarily with polyvinyl chloride (PVC), a material that gives it impact resistance, rigidity and strength.

PVC starts with two simple building blocks: chlorine (57%) from common salt and ethylene (43%) from natural gas. Most of the natural gas utilized to manufacture ethylene is domestically made, which lowers consumption of imported oil products.

Presently, vinyl siding is the number one selection of exterior cladding across the United States and Canada. In fact, U.S. Census Bureau statistics prove twice as many homeowners’ side their homes with vinyl than with any other material. Vinyl siding is offered in an extensive palette of colors, profiles, and architectural styles to help architects, builders, and homeowners in customizing their latest construction, renovation designs, and can balance historical restoration projects.


Many colors and surface textures are available with EIFS. EIFS can also be made into carved or contoured “shapes”, which give a wall a decorative effect and “shape”.EIFS does not support the building (it is nonstructural), but rather is a cladding, like brick veneer or siding. EIFS is very light in weight, has excellent insulation characteristics, and is moderately priced.

EIFS can be used on many types of buildings, including homes, apartments, condos, offices, shopping centers, malls, high rise buildings, stores, hospitals, hotels, resorts, casinos, stadiums, government buildings, military installations, and many more. Simply, EIFS is an exceptionally versatile and attractive product. Hence is is very popular.EIFS can be used on new buildings and on existing buildings. EIFS can also be prefabricated in a factory as ready-to-install wall panels that incorporate an integral metal frame. The completed panels can then be truck to the site, lifted with a crane, and welded to the building’s structural frame.

EIFS can be attached to concrete, brick, masonry, plywood, Oriented Strand Board (“OSB”), various types of gypsum-based sheathings, and cement board.

The EIFS industry trade association says that EIFS now accounts for about 10% of the new wall exterior wall construction in the USA. EIFS was developed in Europe after World War II and was first successfully commercialized in North America in the 1960’s.


EIFS (“Exterior Insulation and Finish Systems”, aka “synthetic stucco”) is an exterior building wall product and is a system of materials. EIFS provides insulation, weatherproofing and a finished surface in a single integrated product. There are various types of EIFS and several ways of installing it, but EIFS is usually applied onto the outside face of exterior building walls, in a series of steps, by professional plasterers, using hand tools. The installation steps are:

Attach the Insulation. Attach rigid foam insulation boards (white, in drawing above) to the building wall (gray, above) using an adhesive or mechanical anchors or both.

Apply the Base Coat. Apply a paste-like adhesive (blue, above) to the insulation, using a trowel, and embed fiberglass reinforcing mesh into the wet adhesive.

Apply the Finish Coat. Apply a colored, textured surface finish (yellow, above) to the dry adhesive layer (blue, above).

There are several types of EIFS, including the traditional barrier type, and the newer EIFS with Drainage type. The above description is of the simplest type – a barrier EIFS.

There are also a number of wall claddings that are not EIFS but that look a lot like EIFS (and vice versa), such as:

Portland Cement Plaster, also known as stucco. This is not EIFS. Stucco has been around for centuries and consists of Portland cement+sand+water, and is applied in a series of layers to a total thickness of about 1/2″ to 3/4″. Stucco is hard and brittle, provides no insulation, and requires “through-joints” (joints that go all the way through the stucco, known as “control joints”) every 150 square feet. Also – and this is important –  there are various forms of “stucco”, some of which are thinner and use synthetic materials, and are also often called synthetic stucco. These “stucco” products contain no insulation and hence also are not EIFS. Confused? It gets better – sometimes the EIFS finish coat (see above) is used as the “top coat” on such stucco products. Such claddings are sometimes still called “EIFS” when they are, in fact, “stucco”. Thus, even though such walls “look like” “EIFS”, they are “stucco”, and the “top coat” – the EIFS finish – should be considered to be a “paint” or coating.

DEFS, Direct-Applied Exterior Finish Systems, or sometimes called Direct Exterior Finish Systems. If you take the insulation layer out of an EIFS and apply the EIFS coatings directly to a substrate, you have what is sometimes called a Direct-Applied Exterior Finish System or DEFS. Since DEFS have no insulation, they are also not EIFS either, although the use of an EIFS finish product on a DEFS makes a DEFS look a lot like an EIFS (hence the confusion).
