Gypsum Board EIFS Details & Specifications




Facades Commercial EIFS Plus

Guarding against water intrusion is the primary concern of any design professional. Beauty and style mean nothing if the function and integrity of the exterior cannot be maintained. That’s why, as a second layer of protection, our engineers came up with Facades WaterGuard™. The WaterGuard™ System is a fill-and-spray directly applied to the building substrate with reinforcing mesh at all joints and penetrations. WaterGuard™ creates a highly water-resistant envelope that helps protect the substrate during construction and in the case of an accidental penetration of the EIFS lamina. When used properly, WaterGuard™ can also be beneficial in preventing condensation within the wall cavity. Now that’s a PLUS!

INTRO to Gypsum Board EIFS specifications

An air barrier Gypsum Board EIFS 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 Gypsum Board EIFS 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 Gypsum Board EIFS 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 Gypsum Board EIFS System. These specifications follow a 3 part format.

TAILOR OUR specifications

These specifications cover all the ways of using the Gypsum Board EIFS System. 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 specification in other parts of the project’s total specification. The project design pros are responsible for ensuring that the project specifications are suitable. This specification is to be used with Gypsum Board EIFS System detail drawings and product data sheets etc. For assistance in preparing your specification contact us.

UNITS

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

WARNING

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.

DISCLAIMER

Info in this specification is to standard detail and product recommendations for the install of the Gypsum Board EIFS 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.
