An Overview of Gypsum Board and Gypsum Panel Products and Plaster Part 2
Gypsum, an important material for building walls and ceilings, is commonly used on construction sites in North Carolina. Oftentimes referred to as drywall, gypsum is a useful resource for building walls and ceilings on the inside of buildings. Although gypsum board and gypsum panel products are primarily made of the same material, it’s important that contractors are cognizant of the various uses for each product.
In part one of this two-part series, the Greensboro construction law lawyers at Cotney Construction Law discussed some important considerations for contractors utilizing gypsum board and gypsum panel products to build structures. Now, we will continue to discuss more important information regarding the use of gypsum board and gypsum panel products in part two.
Gypsum wallboard and gypsum plaster are not suitable for exterior construction where the gypsum will be exposed directly to the weather. Gypsum wallboard can not be used in construction where it will be subjected to direct water exposure or persistent, high humidity conditions. If you do plan to utilize gypsum to construct an exterior area, you must comply with ASTM C1280 and forego installation until suitable weather protection is provided.
The edges and ends of gypsum boards and gypsum panels should meet on the framing members unless they are perpendicular. Edges and ends should touch moderately unless they are positioned in concealed spaces where there is no need for fire-resistance-rated construction, shear resistance, or diaphragm action. For floating angles, fasteners should be attached diligently to avoid accidentally fracturing the face paper with the head of the fastener. In some instances, there is no need for fasteners at the top and bottom of vertical assemblies or on the edges and ends of horizontal assemblies. However, in instances of shear-resistant elements or fire-resistant-rated assemblies, all fasteners must be treated and utilized.
When utilizing gypsum board or gypsum panel products, contractors must remain cognizant of an array of guidelines, rules, and limitations. If you want to learn more about the codes governing gypsum board and gypsum panel products, the International Code Council offers free online resources for contractors and other interested parties.
