Abstract
“EXTERIOR INSULATION and FINISHING SYSTEM’S” (EIFS) are a type of building material that is used as the exterior facing of a building’s exterior wall. EIFS is composed of a number of layers. EIFS is a type of wall surfacing system and needs to be thought of as such a system. EIFS is unique in that it is the only wall material that provides insulation, a finished exterior surface & weather proofing, in a single seamless product. This “single product does it all” attributes accounts for its popularity; EIFS is a good value. EIFS looks like stucco (Portland Cement Plaster), Stucco is a “natural” product, composed of sand, Portland cement & other materials. EIFS is a synthetic product, unlike Stucco, EIFS can be made in large areas without any joints and also with a wide variety of shapes, colors and textures. EIFS is also called as synthetic stucco. Here in this project incorporation of EIFS is directly done in the exterior finishing systems i.e. plastering by selecting few components of EIFS. So EXTERIOR INSULATION in FINISHING SYSTEM is a way of providing thermal insulation for the building. This system even concentrates on providing protection for building against moisture and also aims at crack proof finishing using sustainable green materials. The expression deep energy retrofit lacks precision but broadly suggests a program of existing building improvement that has as one its goals a dramatic improvement in the level of energy efficiency while providing a healthier living environment and improving durability and safety. Adding insulation to exterior walls is often a key piece of a deep energy retrofit. However, this measure is often cost prohibitive.
