INTRO to EIFS (Exterior insulation and finishing system)

An air barrier system minimizes the risk of condensation within the building envelope. It does this by eliminating mass transfer of warm moisture air into the wall assembly to a cold surface where it can condense. A complete air barrier system has individual air barrier parts. Including the connections between them. The air barrier parts must be continuous. Then it is an effective air barrier system. You must take material compatibility and construction sequencing into account. Only then can an air tight assembly ensure long term durability. Also Consider the effects of air tightness on mechanical ventilation.

This doc contains the specifications for this System. These specifications follow a 3 part format.

TAILOR OUR Specifications

These specifications cover all the ways that you can use the EIFS (Exterior insulation and finishing system) System. Most Projects use combinations of these materials and methods. To tailor the specifications to your project use those sections which apply. Place certain parts of the Spec in other parts of the project’s total spec. The project design pros are responsible for ensuring that the project specifications are suitable. This spec is to be used with EIFS (Exterior insulation and finishing system) system detail drawings and product data sheets etc. For assistance in preparing your spec contact us.


English Units are included in parentheses after the Standard International (SI) equivalents. The conversions represent commonly used equivalents.


An air barrier should not be confused with a vapor retarder. A retarder may be used in the wall assembly to retard water vapor diffusion. Also to reduce the risk of condensation. A vapor retarder is placed on the warm side of the wall. It is placed on the interior side in cold climates. A vapor retarder may not be necessary. It depends on the wall components. Also the range of temps and humidity conditions. As well as the mechanical ventilation. A vapor retarder should not be used in warm humid climates.


Info in this spec is to standard detail and product recommendations for the install of the EIFS (Exterior insulation and finishing system) System. It is presented in good faith. We assume no liability to the architecture, engineering or workmanship. To insure that you are using the latest most complete info contact us.
