Topic 5: Conclusion Section reviews the key learning points of the video. 4 FAST FACTS Builders of residential construction typically use stick-frame wood joist and stud elements to frame a house. Panelized framing is when the manufacturer builds the wall, floor, ceiling, and roof framing to the approved specs and ships them to your site. A crane is used to unload panelized framing materials at the site and to put them in place. When panelizing, the first construction step is placing the sub-floor trusses. When using panelizing framing, the roof construction work is handled the same way it would be if you were site building the rest of the house and using trusses for the roof. Windows and exterior doors are hung after the rest of the panels and trusses are in place in panel framing. Paneling can be used as a cost-saving way to frame a house because the labor costs can be controlled. Structural insulated panels, or SIPs, are often used when builders are being particularly conscious of energy-efficiency and environmental concerns. SIPs are pre-manufactured to a design. Although there are standard sizes and shapes, panel processors usually follow CAD designs to form pieces that conform to a builder s plans. SIP frames are joined together by interlocking systems. Sometimes, builders combine stick-framing and SIP paneling, such as using wood joists under panel flooring or trusses under panel roofing. Standard SIP floor framing requires only a girder at the center point for internal support. SIP framing is still only used on a limited basis but is endorsed by those who use it for its construction speed, strength, and energy efficiency. Builders who choose cold-formed steel over wood frequently cite its dimensional stability, meaning it has no shrinkage and exact dimensions. Steel framing materials are similar to stick-frame materials. Site building with steel follows many of the same procedures as stick-framing, but there are distinct differences. Some builders combine wood elements, such as wood roof trusses, with steel framing for cost savings or ease of installation.

5 Steel framing can be more costly than wood framing primarily because skilled framing crews are not in ample supply. Insulated concrete forms can be installed fairly quickly and easily and are energy efficient. VOCABULARY TERMS cold-formed steel: Relatively thin steel that can be bent and shaped, cold, on site. insulated concrete forms (ICFs): Concrete forms that are locked together with tongueand-groove profiles on the top, bottom, and ends. ladder: Used to brace one panel, the ladders are located at the end of each frame panel. light-gauge steel: Steel commonly used for residential framing. Usually consists of 18-to- 20-gauge steel. panelizing: Pre-manufactured framing in panels, delivered ready to install. rebar: Metal rods that are often set in the walls to help strengthen the walls and keep them from cracking. sandwich panels: Two wood panels adhered to foam. structural insulated panels (SIPs): Foam-core panels that are installed by interlocking the panels. structural steel: Steel that can only be shaped at high temperatures. unfaced panels: Foam slabs that notch to accommodate load-bearing studs. PRE-PROGRAM DISCUSSION QUESTIONS 1. What are some of the alternative techniques that can be used to frame a home? 2. How do you find out about new framing techniques? 3. What are the risks involved in using alternative framing techniques? 4. How do you learn how to use alternative framing techniques on a project? 5. What might be some of the pitfalls in working with alternative framing materials/techniques? POST-PROGRAM DISCUSSION QUESTIONS 1. What are the advantages and disadvantages of using the alternative techniques discussed in this program? 2. What are the advantages and disadvantages of using cold-formed steel in framing a home? 3. What are the factors you should consider when determining whether or not to use alternative framing techniques vs. traditional framing techniques? 4. What are the benefits and drawbacks of using SIPs in framing a home? 5. When might it be appropriate to use insulated concrete forms in framing a home? GROUP ACTIVITIES Framing Materials Report Groups will research the different types of materials available for framing and write a brief report of the benefits and drawbacks to using each material. Students should consider environment, cost, availability, ease of use, durability, and strength in their reports. 5

6 Framing Methods Report Assign small groups one of the alternative framing methods discussed in the video and ask them to research the process for building a home using their assigned method. Based on their research, groups should create a 3-to-5-minute presentation describing the process. Students should be encouraged to create diagrams, etc., to use in presenting their findings to the larger class. Alternative Framing Tools Assign small groups one of the framing techniques discussed in the video and ask them to identify the key tools and resources (such as an engineer) that might be needed to frame a home and identify which tools should be used for each step in the framing process. INDIVIDUAL STUDENT PROJECTS Building Supply Store Trip Ask students to visit a building supply store and price out the different types of framing products (i.e., wood, metal, concrete and polystyrene blocks) to determine the cost differences between each type of product. Then provide them with the amount of material needed to frame a house and ask them to calculate the cost difference for each product. SIP Framing Students research the two types of SIPs and develop a brief report detailing the differences between sandwich panels and unfaced panels. The report should include when it is most appropriate to use each type of SIP and the benefits and drawbacks of each type. Cold-formed Steel Framing Students research the effects of settling on a building (due to lumber shrinkage) and discuss the benefits of using cold-formed steel to frame a house and when a builder might decide to use this technique in place of traditional wood framing. INTERNET ACTIVITIES Alternative Framing Products Research Ask students to use the Internet to research alternative products used in framing buildings, and have them develop a summary report on the appropriate application, benefits, and challenges of each approach. Energy/Material Conservation Framing Ask students to use the Internet to research energy-efficient framing methods and have them develop a list of pros and cons for using these types of methods over more traditional methods of framing. 6 Safety Precautions when Framing Students research the safety precautions they should take when framing a building using alternative framing techniques. Their list should include equipment and tips framers can use to make their workplace safer.

7 ASSESSMENT QUESTIONS Q: What is the panelizing technique for framing a house? A: It uses pre-manufactured framing in panels, delivered ready to install. Feedback: The manufacturer builds the wall, floor, ceiling, and roof framing to the approved specs and ships them to your site. A crane is used to unload the materials and put them in place. Q: Which of the alternative framing methods comes with ladders at the end of each panel? (a) Panelizing (b) Structural insulated panels (c) Cold-form steel (d) Insulated Concrete Forms A: (a) Feedback: Panelizing panels come with ladders at the end of each panel. The ladder is used to brace one panel to the next while you re working. Q: What is cold-formed steel? A: Cold-formed steel is relatively thin steel that can be bent and shaped, cold, on site. It can be used to frame a home. Feedback: Cold-formed steel is distinguished from structural steel because structural steel can only be shaped at high temperatures. Q: Builders who choose over wood frequently cite its dimensional stability. A: cold-formed steel Feedback: Cold-formed steel won t rot and it s also resistant to insects. But using steel for framing can be costly if you don t make the best use of each piece of material. Q: Framing the walls with SIP paneling is performed somewhat similarly to: (a) panelizing (b) stick framing (c) balloon framing (d) post-and-beam A: (b) Feedback: Framing the walls with SIP paneling is akin to stick framing. The sections are assembled on the deck and raised into place. Q: Describe the insulated concrete foam method for framing a building. A: The forms lock together with tongue-and-groove profiles on the top, bottom and ends. The forms are stacked by interlocking the tongue-and-groove channels. Feedback: When using insulated concrete foam, every wall will need to be reinforced and the accurate placement of the rebar is critical. Q: When using insulated concrete foam, the has to sit in the middle of the 1-footon-center core voids in the waffle forms. A: rebar 7

8 Feedback: The rebar has to sit in the middle of the 1-foot-on-center core voids in the waffle forms, starting with a bar rising up the center of the corner cavity. So, it s important to know how your foam forms will lay out and to mark the footing forms for the proper rebar locations. Q: When measuring for steel studs, how many inches will you probably allow on center between studs? (a) 12 inches (b) 18 inches (c) 24 inches (d) 30 inches A: (c) Feedback: Because steel is stronger than wood, when measuring for studs, you will probably allow 24 inches on center between studs. Q: Some builders believe that wood combined with steel framing allow easier installation of subfloors. A: I-joists Feedback: Some builders combine wood elements, such as wood roof trusses, with steel framing for cost savings or ease of installation. Q: SIPs are often used when builders are being conscious of: (a) ease of installation (b) safety (c) energy efficiency (d) cost A: (c) Feedback: SIPs are often used when builders are being particularly conscious of energyefficiency and environmental concerns.
