Structural: Design structural wall for maximum allowable deflection, normal to the plane of the wall, of L/240.

8 Ultimate tested wind load resistance: +175 psf ( kPa). Apply appropriate safety factor as required by code. Higher ultimate loads can be achieved with adequate stiffness (and sheathing attachment for frame walls) of supporting construction. Refer to Tech Hotline No. 0894-E. All trim and projecting architectural features must have a minimum 1:2 (27 degree) slope. A minimum of (19mm) XPS insulation board must remain if areveal is cut in the insulation board. A minimum of 1 thickness of XPS board is needed when a reveal is specified. Construct a site built mock-up using materials and sub-trades associated with the project to verify installation, sequencing, detailing, and aesthetics.

9 Fire: Minimum required thickness of XPS foam plastic insulation board is 1 (25mm). Maximum allowable thickness is 6 (152mm) on types I, II, III, or IV. construction. If walls are required to have an hourly fire-resistance rating, the maximum allowable thickness is 2 (51mm) over maximum 2-hour rated nonload bearing frame walls, or 6 over, (concrete or masonry) mass walls. Refer to ICC-ESR 1748 for more information. XPS insulation board has a service temperature limit of 165 F (74 C). The use of dark colors (Light Reflectance Value of less than 20) is not recommended. Moisture Protection: Provide minimum 6 (152mm) clearance above landscaped areas (soil, grass, and other non-paved surfaces), and a minimum of 1 ( ) above finished grade areas, (pavement, patios, ) as required by code.

10 StoTherm ci XPS systems are not intended for use below grade. Direct incidental moisture to the exterior a maximum of every third floor. Weep spacing at window, door, floor line and other similar penetrations are to be determined by the Design Professional. Refer to StoTherm ci XPS Specifications, Product Bulletins, Technical Hotlines, Sto Installation Manuals, and Maintenance Guides for the most complete and current information. See Tech Hotline Nos. 0403 BSc, 0603 BSc for important information on detailing and moisture control in wall assemblies. Joints: Provide minimum (19mm) wide joints in StoTherm ci where they exist in the substrate or supporting construction, where the cladding adjoins dissimilar construction or materials, at changes in building height, at expansion, control, and cold joints in construction, and at floor lines in multi-level wood frame construction.
