Sentry Stucco CI Wall System – Section 07 24 16

1 Sent ry Stucco CI Wall System Section 07 24 16 Water-drainage, mechanically-attached polymer-modified Stucco System incorporating continuous external insulation and a water-resistive barrier INTRODUCTION This specification has been assembled to enable the design professional to select or delete sections to suit the project requirements and is intended to be used in co njunctio n with Senergy typical details, product bulletins, technical bulletins, etc. DESIGN RESPONSIBILITY It is the respo nsibility of both the specifier and the purchaser to determine if a product is suitable for its intended use.

2 The designer selected by the purchaser shall be respo nsible for all decisio ns pertaining to design, detail, structural capability, attachment details, shop drawings and the like. The Wall Systems business of BASF Corporation (herein referred to as BASF Wall Systems ) has prepared guidelines in the form of specifications, typical application details, and product bulletins to facilitate the design process o nly. BASF Wall Systems is not liable for any errors or omissions in design, detail, structural capability, attachment details, shop drawings or the like, whether based upon the information provided by BASF Wall Systems or otherwise, or for any changes which the purchasers, specifiers, designers or their appointed representatives may make to BASF Wall Systems published comments.

3 DESIGNING AND DETAILING A SENERGY Sentry Stucco CI WALL System General: The System shall be installed in strict accordance with current recommended published details and product specifications from the System s manufacturer. A. Wind Load 1. Maximum deflection not to exceed L/360 under positive or negative design loads. 2. Design for wind load in conformance with local code requirements. B. Substrate Systems 1. Acceptable substrates are: PermaBase Cement Board and other cement-boards co nforming with ASTM C1325 (Type A-exterior); po ured co ncrete/unit masonry; ASTM C1177 type sheathings, including, Weather Def ense Platinum sheathing, GreenGlass sheathing, e XP sheathing, GlasRoc sheathing, Securock glass-mat sheathing, and DensGlass exterior sheathing; gypsum sheathing (ASTM C79/C1396); Exposure I or exterior plywood (Grade C/D or better); or Exposure I OSB.

4 2. Painted and otherwise coated surfaces of brick, unit maso nry, and co ncrete shall be inspected and prepared as approved by BASF Wall Systems before applicatio n. The applicator shall verify that the proposed substrate is acceptable prior to the Sentry Stucco CI System installatio n. 3. The s ubs trat e sys tem s s ha ll be engineered with regard to structural performance by others. 4. Refer to Sentry Stucco CI System Lath and Trim Accessories technical bulle ti n for more detailed information regarding metal lath, woven wire, trim requirements, etc.

5 C. M o isture Co nt ro l 1. Prevent the accumulatio n of water behind the Sentry Stucco CI System , either by co ndensatio n or leakage t hro ug h t he wa ll co nst r uctio n, i n t he de sig n a nd det ai li ng o f the wa ll ass em bly. a. Provide flashing to direct water to the exterior where it is likely to penetrate compo nents in the wall assembly, including, above windo w and door heads, beneath window and door sills, at roof/wall intersectio ns, decks, abutments of lower walls with higher walls , above pro jecting features, at the base of the wall and anywhere else required by local code.

6 [b. Senergy SENERSHIELD-R air/water-resistive barriers can be used, provided a subsequent layer of Tyvek Stuc co Wrap is applied over the BASF Wall Systems ro ller applied air/water-resistive barrier.] c. The water resistive barrier must be installed over the substrate according to manufacturer s specificatio ns and applicable building code requirements. d. Openings must be f lashed prior to windo w/door, HVAC, etc. installatio n to provide moisture protectio n of the building frame and interior. Refer to Senergy s Secondary Moisture Protection Barrier Guidelines for Senergy Stucco Wall System bulletin.

7 [e. Air Leakage Preventio n: provide co ntinuity of air barrier System at foundation, roof, windows, doors and other penetrations through the System with connecting and compatible air barrier components to minimize condensation and leakage caused by air movement.] D. Grade Co ndition 1. Se ntry Stucco CI Wall System is not intended for use below grade or on surfaces s ub ject to co nti nuo us o r intermittent immersio n in water or hydrostatic pressure. Ensure a minimum 4 ( ) clearance above grade or as required by code, a minimum 2 ( mm) clearance above finished grade (sidewalk/co ncrete flatwork).

8 E. Trim, Projecting Architectural Features NOTE TO SPECIFIER: Installation of the Se nt ry Stucco CI System with trim shapes that incorporate expanded polystyrene (EPS) outside the slope guidelines referenced in this specification may still qualify for a standard w arranty; how ever, increased maintenance and premature deterioration of the trim shapes that incorporate expanded polystyrene (EPS) shall be expected and any deleterious affects caused by the lack of slope w ill not be the responsibility of BASF Wall Systems.

9 T he design professional has the option to build according to his/her project needs. T he design professional must also consider geography, climate, building orientation, w all orientation and adjacent building components w hen designing with trim shapes that incorporate expanded polystyrene (EPS). T he slope guidelines referenced below are provided to offer assistance to the ow ner and/or design professional.

10 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 cm (12") [ 15 cm in (6" in 12")]. Increase slope for northern climates to prevent accumulatio n of ice/sno w o n t he s urf ace . 2. The Sentry Stucco CI System was designed and tested to be applied to vertical surfaces. As the slope of the wall System applicatio n decreases, the chance for premature deterioratio n of any wall System increases.
