Gypsum Association Releases Revised Technical Documents
The Gypsum Association (GA) is pleased to announce that two technical documents, GA-236, Joint Treatment Under Extreme Weather Conditions and GA-253, Application of Gypsum Sheathing, have been revised and updated. Both documents are available for free download from the GA Bookstore as a service to the design and construction community.
For more than 15 years, GA-236 has provided special instructions for treating joints during weather extremes. Periodic revision of the document ensures that recommendations reflect current best practices. Very high or very low temperatures and humidity levels affect the drying times of joint compounds. Moreover, swings in temperature or moisture levels can cause movement in wood or steel framing. GA-236-2016 continues to offer common sense measures designed to mitigate problems associated with extreme weather.
