owner and/or design professional. Final design of any building is the responsibility of the design professional. 1. Minimum slope for all projections shall be 1:2 (27) with a maximum length of 30.5 cm (12") [e.g. 15 cm in 30.5cm (6" in 12")]. Increase slope for northern climates to prevent accumulation of ice/snow on the surface. 2. The Sentry Stucco CI System was designed and tested to be applied to vertical surfaces. As the slope of the wall system application decreases, the chance for premature deterioration of any wall system increases. 3. Low sloping conditions are subject to more extreme heat. Low sloped areas are known to produce an increase in wall surface temperature which can lead to accelerated weathering of the low sloped surface. 4. The use of dark colors over EPS insulation trim shapes must be considered in relation to wall surface temperature as a function of local climate conditions. Select a Finish Coat color with a light reflectance value (LRV) of 20% or higher. The use of dark colors (LRV less than 20%) is not recommended with trim shapes that incorporate expanded polystyrene (EPS). EPS has a sustained service temperature limitation of approximately 71C (160F).] F. System Joints 1. Expansion joints in the system are required at building expansion joints, at prefabricated panel joints, floor lines of wood frame construction, where substrates change and where structural movement is anticipated. Detail specific locations in construction drawings. 2. Control joints are recommended at a minimum of every 13m 2 (144ft 2 ) of wall surface area and where specified by the design professional. The maximum uncontrolled length or width is 5.5 lineal meters (18 lineal feet) and a maximum uncontrolled length to width ratio of 2 : 1. Detail specific locations in construction drawings. 3. It is the sole responsibility of the project design team, including the architect, engineer, etc., to ultimately determine specific expansion and control joint placement, width and design. 4. Sealant joints are required at all penetrations through the Sentry Stucco CI System (windows, doors, lighting fixtures, electrical outlets, hose bibs, dryer vents, etc.). Refer to Sentry Stucco CI System Typical Details . G. Decks Wood decks must be properly flashed prior to system application. The Sentry Stucco CI System must be terminated a minimum of 25 mm (1") above all decks, patios, sidewalks, etc. H.Coordination with other trades 1. Evaluate adjacent materials such as windows, doors, etc. for conformance to manufacturer's details. Adjacent trades shall provide scaled shop drawings for review. [2. Air Seals at any joints/gaps between adjoining components (penetrations, etc.) are of primary importance to maintain continuity of an air barrier system and must be considered by the design professional in the overall wall assembly design. Install air seals between the primary air/water-resistive barrier and other wall components (penetrations, etc.) in order to maintain continuity of an air barrier system.] 3. Provide protection of rough openings in accordance with Senergy Moisture Protection Guidelines for Senergy Stucco Wall System before installing windows, doors, and other penetrations through the wall. 4. Install copings and sealant immediately after installation of the Sentry Stucco CI System and when Senergy coatings are completely dry.

Refer to all project drawings and other sections of this specification to determine the type and extent of work therein affecting the work of this section, whether or not such work is specifically mentioned herein. B. System Description: Composite wall system of water-resistive barrier, rigid insulation, fasteners, Base Coat, Reinforcing Mesh, and Finish Coat. C. Senergy products are listed in this specification to establish a standard of quality. Any substitutions to this specification shall be submitted to and receive approval from the Architect at least 10 days before bidding. Proof of equality shall be borne by the submitter. D. The system type shall be Sentry Stucco CI System as manufactured by BASF Corp. - Wall Systems, Jacksonville, Florida (herein referred to as BASF Wall Systems). 1.2 DEFINITIONS A. Continuous Insulation Stucco System: A wall system where the Base Coat is applied to a uniform thickness of nominal 10 mm (3/8") over continuous exterior insulation. The Base Coat thickness is not dependent upon the number of layers or thickness of Reinforcing Mesh. The Reinforcing Mesh is installed over the surface of the insulation board. The Base Coat is applied over the Reinforcing Mesh. Protective Finish Coats, of various thicknesses, in a variety of textures and colors, are applied over the Base Coat. 1.3 RELATED SECTIONS A.
