Eifs claddings are used to create a monolithic finish on a building. It comprises several layers between the sheathing and the exposed finish. An exterior insulation finishing system eifs also known as ewi exterior wall insulation systems or external thermal insulation composite systems etics is a type of cladding system that provides exterior walls with an insulated finished surface and waterproofing in an integrated composite material system.

Couple this with interior vapor barriers required by just about every model building code and you have problems. Because barrier eifs itself blocks the movement of water and vast quantities of water vapor. Keep in mind that every other exterior cladding system for residential homes allows water and water vapor to escape back to the atmosphere. Uncoated sheet edges can be very absorbent and they may wick water from adjacent surfaces such as waterproof decks and roofs.

It is composed of expanded polystyrene insulation board covered with glass fiber mesh and layers of thin synthetic coating for the. Excellent protection against moisture intrusion as well as substantial energy savings thanks to a thermally efficient building envelope that. The system starts with a water barrier attached to the sheathing such as house wrap felt paper or cementitious gypsum board. By the mid 1980s eifs was commonly found in most mid to upper priced residential developments throughout the country.

The weathertight exterior coating creates a weatherskin and a face seal to the cladding that is very airtight. According to the definitions of the international building code and astm international an exterior insulation and finish system eifs is a nonload bearing exterior wall cladding system that consists of an insulation board attached either adhesively or mechanically or both to the substrate. An integrally reinforced base coat. Eifs is the acronym for external insulation and finishing system.

Stotherm ci is a high performance exterior wall cladding system that integrates a seamless air and moisture barrier with continuous insulation ci and advanced drainage capabilities. The finish is comprised of polymeric organic bonded aggregate and cement reinforced with a glass mesh. The house was actually wrapped in a proprietary lightweight synthetic cladding known as an exterior insulation and finishing system eifs a multilayered wall system with thermal insulation built right in. And a textured protective finish coat.

Contractors found stucco to be a good repair choice for buildings damaged during the war. But that would all change by the end of the century.
