## Lessons

- [About this Course](https://gypsum.org/lesson/about-this-course-2/) - The Gypsum Association is a Registered Provider with The American Institute of Architects Continuing Education Systems (CES). Upon request by an AIA member, the Gypsum Association will report successful completion of this course to CES. Please provide AIA Member Number to shines@gypsum. org. Certificates of Completion for non-AIA members are also available on request. This
- [Fasteners and Adhesives](https://gypsum.org/lesson/fasteners-and-adhesives-2/) - Gypsum panels are typically installed to framing members using fasteners, or a combination of fasteners and adhesive. Fasteners are defined as nails, screws, or staples used for mechanical application of gypsum panel products. While a variety of fasteners may be used to attach gypsum panels, all fasteners must be manufactured to specific minimum criteria to
- [Learning Objectives](https://gypsum.org/lesson/learning-objectives-2/) - After completing this course you will better understand: The terms and materials defined in GA-216 Application of Gypsum Sheathing The different methods of applying gypsum panel products; The basic environmental conditions for installing gypsum panel products; The general requirements for installing gypsum panel products; The various fasteners used with gypsum panel products and requirements for
- [Definitions](https://gypsum.org/lesson/definitions-done/) - The term gypsum panel products is used throughout GA-216 and is defined in ASTM C11, Standard Terminology Relating to Gypsum and Related Building Materials and Systems as the general name for a family of sheet products consisting essentially of gypsum. Gypsum board is defined in ASTM C11 as, “the generic name for a family of
- [Panel Installation and Joints Between Panels](https://gypsum.org/lesson/panel-installation-and-joints-between-panels-done/) - Panels should be installed so that they are in contact with each other; however, they should not be forced together. Ends and edges of panels should be smoothed as necessary to obtain neat fitting joints and to permit panels to rest flat against framing members. Panels and framing members should be clean and free of
- [Special Applications](https://gypsum.org/lesson/special-applications-add-question/) - Floating Interior Angles In wood-frame construction, the floating angle method of application can be used to minimize the effects of truss uplift and the possibility of fastener popping in areas adjacent to wall and ceiling intersections. The floating angle method is outlined in Section 4.9 of GA-216. Special clips may be used to create a
- [Environmental Conditions](https://gypsum.org/lesson/environmental-conditions-2/) - As with all construction materials, gypsum panel products must be installed and stored under specific environmental conditions. Failure to comply with basic application and maintenance requirements may limit the service life of the material. Gypsum panels should not be installed where they will be subject to direct exposure to water or continuous high humidity conditions.
- [General Application Provisions](https://gypsum.org/lesson/general-application-provisions-2/) - Framing members to which gypsum panel products are to be attached should be installed so that they are straight and true. Bent, twisted, cut, split, or otherwise damaged framing members should be not be used. The attachment surface of any framing, furring member or fastening surface shall not vary more than 1/8 in. (3 mm)
- [Introduction to GA-216-2021 Application and Finishing of Gypsum Panel Products](https://gypsum.org/lesson/introduction-to-ga-216-2021-application-and-finishing-of-gypsum-panel-products/) - GA-216 Application and Finishing of Gypsum Panel Products addresses the application and finishing of gypsum panel products and related items to interior walls and ceilings. Installation of gypsum panel products to exterior soffits also is covered. The material in GA-216, and in this course, is not applicable to the application or finishing of gypsum sheathing.
- [Application of Panels Using Adhesive](https://gypsum.org/lesson/application-of-panels-using-adhesive/) - Adhesives used to attach panels to wood framing members must comply with ASTM C557, Standard Specification for Adhesives for Fastening Gypsum Board to Wood Framing. Panels can be attached to metal framing members using adhesive.
