The Wood Products Council 2011 At the end of this program, participants will be able to: 1. Understand what SIPs are, how they developed, and their advantages over non-wood building envelopes. 2. Through case study examples, participants will examine a variety of SIP applications in commercial buildings. 3. Visualize how a SIP building is constructed and how roofs, walls and floors are designed and constructed. 4. Understand the structural capabilities of SIPs, examining representative spans, loads and other design criteria.

2 Learning Objectives At the end of this program, participants will be able to: 1. Understand what SIPs are, and how they are constructed. 2. Understand why SIP's benefits make them an appropriate choice for many building applications. 3. Visualize how a SIP building is constructed and contrast SIP building details to a conventional wood framed building or non-wood building. 4. Understand the codes, standards, performance testing, and certification procedures that pertain to SIPs 5. Understand structural capabilities of SIPs including representative spans and loads. WHAT ARE SIPS? SIPs are composite, high performance, self-supporting, supporting structural building panels with an insulating core of rigid foam usually EPS and structural facings or skins, most commonly of 7/16 thick oriented strand board (OSB). 5 6 SIPs RTA Panelized System Combining the efficiency of panelization and accuracy of machine cut panels in creating 5 building elements all at once: 1) Structural Assembly for both gravity and lateral loads 2) Insulation 3) Air Barrier and Vapor Retarder 4) Wire chases included 5) Flat Nailable Surfaces for interior and exterior finishes Why Use SIPs? Super Strength January 1995-Kobe, Japan 7.2 magnitude earthquake Damage over $100 billion Six SIP homes Suffered NO structural damage 1998-Clermont, Georgia This SIP house survived a tornado with superficial damage while 27 conventional houses around it were destroyed. SIPs are built for speed! 7 8

3 SIPs-Green Benefits Energy efficiency 50-70% less energy usage Resource efficiency OSB-from renewable, sustainable harvested resource EPS cores-use non-cfc blowing agent, 98% air, only 2% petroleum Waste minimization-less job-site waste Environmentally friendly manufacturing- mfg residues recycled Healthy indoor air quality Qualify for green building programs SIPs help the environment Carbon storage in the wood materials Reduced heating, cooling and electrical loads means: Reduced emissions, less air pollution, less CO2 Building an energy efficient envelope will do far more to conserve resources than filling the home with green or sustainable products. - Green Builder Magazine SIPs-Advantages For Contractors SIPs Save Time, Labor and Money!

9 STRUCTURAL CONCERNS SIPs in the IRC Code reports, load charts and assumptions for floor, wall and roof applications. 33 The 2007 IRC Supplement to the 2006 IRC included d SIPs Section R614 Prescriptive use The 2009 IRC includes SIPs as walls Prescriptive The 2010 CRC adopted the 2009 IRC Pay attention to the scope Very limited use 34 SIPs and Code Reports SIPs and Code Reports Once the scope of the CRC is exceeded or You are following the CBC Code Reports are in order Evaluation Service ICC-ES Product Certification Agencies NTA IAPMO APA AAMA UL ANSI or IAS accredited ISO Guide 65 IAS is a sister of ICC-ES 35 36

10 SIPs and Code Reports Load Charts / Load Tables Some MFG s have proprietary reports Some SIPA members have a common code report Axial capacity Transverse capacity Shear Wall capacity Diaphragm capacity Point load capacities Header capacities Read the footnotes Panel Sizes Panels can be manufactured in sizes from 2 x8 Up to 8 x24 Splines - Panel Connectors SIP mfgrs typically have three basic types of splines or panel connectors. Listed in order of cost effectiveness they are: The block or surface spline. The I-Joist spline. The lumber spline

11 Splines - Panel Connectors The block or surface spline. Either a 3 wide mini panel or A 3 wide piece of OSB This spline type does not increase the panels span capability. Used with all width panels including 8 wide panels. Splines - Panel Connectors The I-Joist spline. Less thermal bridging than with solid lumber splines. Adds strength to the panels. Maximum spacing of 4 oc This limits the maximum width of panel to 4 with this type of spline Splines - Panel Connectors The lumber spline. Single or double 2x s LVL may be used Maximum spacing 4 oc 4oc Adds strength-both axially and transverse. Floor Panel Details Floor panels must have a minimum of 1 ½ of bearing on the bottom skin. If ledger type bearing is used there is typically a capacity reduction

12 Check the Mfgrs span charts for design capacities. Each spline type will have different capacities. Typically, floor panels can span upwards of 14 to 16 depending on the spline type used. Floor Panel Details Floor panels can not cantilever over a support and carry wall loads from above. Solid blocking must be incorporated beneath posts from above. The EPS core will compress if solid blocking is not used. Floor Panel Details Wall Panel Load Charts Wall Panel Details Wall panels will have capacities for both: Axial loading Transverse loading Different capacities for lumber and box splines. The top and bottom of the wall panel will have 2x plating. The top of the wall may have a cap plate for additional bearing capacity. Wall panels will have 2x plating at the corners or changes in direction along with long screw fasteners

13 Openings will have 2x plating surrounding the opening. Maintain a minimum of 1 at the corners to an opening. Maintain a minimum of 1 above openings to allow for headers: SIP header Insulated headers Conventional headers Wall Panel Details Wall panels will have 1 to 1.5 diameter electrical chases Horizontally Vertically Top and bottom plates are drilled during installation to access the vertical electrical l chases. Wall Panel Details Wall Panel Details Typical platform bearing of floor framing on SIP walls can be used. You must insulate the rim cavity. You must provide for diaphragm shear transfer. This condition is typical to stick framing. Diaphragm shear transfer into walls is not so good. Clip angles req d Rim panels can be used on top of foundation walls: Mini i wall panel Makes for platform type framing conditions. Top flange hanger detail is useful for multilevel construction. ti Good diaphragm shear transfer into walls from floor diaphragm. Wall Panel Details 51 52

14 Wall Panel Details Three top of wall details are commonly used: Square cut wall panel with 2x beveled wedge Square cut wall panel with solid beveled block Beveled wall panel Minimum 1 ½ req d for bearing of bottom skin. Flat roof panels can be treated like floor panels Roof Panels Roof Panel Details Common overhang details: Square cut roof panel Plumb cut roof panel Ladder framing Reduced overhang details: SEISMIC CONSIDERATIONS FOR SIPS Shear wall and diaphragm applications for SIPs

15 SIPs as Shear Walls SIPs as Diaphragms SIPs can be used as shear walls. ICC-ES has not evaluated for SDC s D, E & F yet AC04 Appendix A recently published NTA has evaluated for all SDC s A F Some Mfgrs have LARR based on ICC-ES report with added shear wall capacities 57 SIPs can be used as diaphragms ICC-ES and NTA have evaluated for this use Testing is based on ASTM E455 Mfgr code reports will have capacities 58 Course Evaluations In order to maintain high-quality learning experiences, please access the evaluation for this course by logging into CES Discovery and clicking on the Course Evaluation link on the left side of the page.
