Division 7 Ebook Page 196 Senergy® Sentry Stucco CI Wall System Overview

DESCRIPTION Sentry Stucco CI Wall System is a continuously insulated, water-drainage stucco system that includes a water-resistive barrier to protect the substrate. The system offers design flexibility, aesthetic appeal and energy savings. Integrated system components include mechanical fasteners, a water- resistive barrier, means of drainage, an XPS (extruded polystyrene) insulation board, base coat, reinforcing mesh, 100% acrylic polymer finish and other accessory components as described in the system specification and technical bulletins. Apply the system over acceptable substrates: Exposure I or exterior plywood sheathing (Grade C-D or better), Exposure I OSB. PermaBase cement-board by National Gypsum and other cement- boards (ASTM C1325 Type A Exterior). ASTM C1177 type sheathings, including DensGlass exterior sheathing, eXP sheathing, GlasRoc sheathing, Securock glass mat sheathing; Weather Defense Platinum sheathing and GreenGlass sheathing. Gypsum sheathing (ASTM C79/ASTM C1396). Concrete and unit masonry. The Sentry Stucco CI Wall System is based upon the time tested Senerthik Wall System design that has passed rigorous tests including Full-Scale Fire, Wind-Load,Wind-Driven Rain,Abrasion Resistance and Moisture Drainage. Finishes are available in a limitless color selection and offer performance enhancement options, including increased resistance to dirt pick-up and mildew. Sentry Stucco CI Wall System features exceptional durability and low maintenance. USES New or retrofit commercial and residential construction where continuous insulation and impact resistance are design considerations. ADVANTAGES Blanket of continuous external insulation provides high R values, lowers heating and cooling costs Water-drainage design drains incidental moisture to the exterior Polymer modifed base coat provides weather-, impact- and puncture- resistance Unlimited colors, textures and architectural details support design flexibility Crack-, abrasion- and dirt-resistant DESIGN CONSIDERATIONS Maximum allowable deflection L/360: based on stud properties only. The design wind load shall not exceed the system's allowable wind load as stated in applicable code reports. Details shall conform with BASF Wall Systems' recommendations and shall be consistent with the project requirements. Control joints and trim accessories are required.Control joint placement is required in the Senergy Sentry Stucco CI StuccoWall System every 144 ft 2 . Consult the framing and sheathing manufacturer for design and application considerations. Expansion joints are required in the system where they exist in the substrate, where the system adjoins dissimilar construction, at changes in substrates and at floor lines in multilevel wood frame construction. System shall terminate at expansion joints. Sealant joints shall be detailed and installed per sealant manufacturer's recommendations. A minimum 6:12 slope is required on all horizontal surfaces greater than 1". Backer rod,sealant and flashing are required at door and window openings. BEST PRACTICES FOR INSTALLERS General All flashing should be installed per codes prior to the installation of Sentry Stucco CI Wall System. A mock-up of the Sentry Stucco CI Wall System showing all components should be prepared using the same tools and skills that will be used in actual construction, and the sample should be kept at the jobsite during construction. It is recommended that the building should carry a minimum of 90 percent of the dead building load and that the interior gypsum should be installed prior to installation of the Sentry Stucco CI Wall System. Coordination of other trades is recommended so that wall penetrations for cable, electricity, water and vents are installed with proper enclosures prior to installation of the stucco. Pail components must be kept at a minimum of 4C (40F) and at a maximum of 43C (110F) during shipping and storage. A minimum temperature of 4C (40F) is required during application of liquid components and until completely dried. Protect dry (bagged) products from moisture. No additives are permitted to any components unless specifically approved by BASF Wall Systems. Follow the application instructions for each component. Windows and doors may permit some water to pass through the frame materials or joints.To reduce the potential for intruding water to degrade water-sensitive sheathing and framing, and to keep water out of the stud cavity, rough openings must be properly protected and a means provided to allow intruding water to escape. Sentry Stucco CIWall System is not designed for soffit or ceiling applications. Do not use below grade; system must terminate a minimum of four inches above grade, or as required by code, a minimum 2" clearance above finish grade (sidewalk/concrete flatwork). Framing/Sheathing Framing, plywood and OSB should have moisture content of less than 19 percent.Wet wood will shrink and deform, potentially resulting in cracking. Sheathing must be securely fastened per applicable building code and manufacturer's requirements. Sheathing must be attached with corrosion resistant fasteners. All substrates must be clean, dry and sound without planar irregularities greater than 1/4" in 10'. Sheathing must be protected with a weather resistant barrier installed over the sheathing per applicable building code and manufacturer's requirements. Sheathing must be installed according to code requirements in effect. SENERGY SENTRY STUCCO CI WALL SYSTEM OVERVIEW
