Learning ObjectivesAt the end of this program, participants will be able to:

S1. 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.roofs, walls and floors are designed and constructed.

4. Understand the structural capabilities of SIPs, examining

representative spans loads and other design criteriarepresentative spans, loads and other design criteria.

Learning Objectives

At the end of this program, participants will be able to: 1. Understand what SIPs are, and how they are constructed. , y2. 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.g g

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 supportingperformance, self-supporting, structural building panelswith an insulating core of rigid foam – usually EPS and structural facings or skins, most commonly of 7/16” thick yoriented strand board (OSB).

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 loads2) Insulation2) Insulation3) Air Barrier and Vapor Retarder4) Wire chases included5) Flat Nailable Surfaces for interior and exterior finishes

SIPs are built for speed!7

Why Use SIPs?—Super Strength

SIPs-Green Benefits

Energy efficiency – 50-70% less energy usage Resource efficiency

OSB-from renewable sustainable harvested resourceOSB from renewable, sustainable harvested resourceEPS 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 environmentSIPs help the environment

Carbon storage in the wood materialsReduced heating, cooling and electrical loads means:Reduced emissions, less air pollution, less CO2Reduced 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 MagazineGreen Builder Magazine

Splines - Panel Connectors

SIP mfgrs typically have three basic types of splines or panel connectorsconnectors.Listed in order of cost effectiveness they are:effectiveness they are:

The block or surface splinespline.The I-Joist spline.The lumber splineThe lumber spline.

40


The block or surface spline.Either a 3” wide mini panel

orA 3” wide piece of OSBThis spline type does notThis spline type does not increase the panels span capability.Used with all width panels including 8’ wide panels.

41


The I-Joist spline.Less thermal bridging than with solid lumber splines.Adds strength to theAdds strength to the panels.Maximum spacing of 4’ ocThis limits the maximum width of panel to 4’ with this type of splinethis type of spline.

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 capacitythere is typically a capacity reduction.

44

Floor Panel Details

Check the Mfgrs span charts for design capacities.Each spline type will have different capacities.Typically floor panels canTypically, floor panels can span upwards of 14’ to 16’ depending on the spline type

45

Floor Panel Details

Floor panels can not cantilever over a support and carry wall loads fromand carry wall loads from above.Solid blocking must be incorporated beneath posts from above.

The EPS core willThe EPS core will compress if solid blocking is not used.
