For example, a type G screw should be used for attaching gypsum to gypsum and type W screws are for gypsum to wood framing. The correlation matrices between defects and between defects and probable causes complement these classifications.

Flexible Cement Board (PermaBase Flex® BRAND Cement Board) R. Gypsum Sheathing (Gold Bond® BRAND Gypsum Sheathing) S. Fire-Resistance Rated Gypsum … The Drywall Safety Act of 2012 (PL 112-266) was signed into law by President Barack Obama on Jan. 14, 2013. R702.3.5 and (Table R702.3.5) The nailing pattern on walls is … In the context of a global inspection system for the non-structural building envelope, the classification of diagnosis methods is organised in ten categories: assisted sensory analysis; electrical methods; thermo-hygrometric methods; sound and acoustic methods; nuclear methods; hydric methods; mechanical methods; pressure methods; colour methods; and chemical methods. 2017, Amaro et al. I. ” Journal of Materials in Civil Engineering, ASCE, 20 (2): 128-136. Drywall This standard is referenced in building codes such as the International Building Code, International Residential Code, and the National Fire Protection Association (NFPA) NFPA 5000: Building Construction and Safety Code. Using both lists, the relationship between each defect and each cause is determined according to the probable contribution of the causes to the occurrence of a defect. Inspection, Diagnosis, and Rehabilitation System for Vinyl and Linoleum Floorings in Health Infrastructures, Harmonising correlation matrices within a global building expert knowledge-based inspection system, Mechanical and Non-Destructive Testing of Plasterboards Subjected to a Hydration Process, Cuantificación porcentual de los daños existentes en los revestimientos interiores de las viviendas españolas. Supply and installation of gypsum board ceilings. Its main purpose is to help the inspector to be more objective in his in situ activities and, at the same time, to standardize procedures. Acceptable moisture levels vary depending upon the type of material. Esta investigación se centra en la determinación de los daños más usuales en los alicatados, enfoscados, guarnecidos, falsos techos y solados interiores, obtenidos en el conjunto de España a partir de los requerimientos presentados por los usuarios. found in refereed journals or in congress proceedings. and Building Materials. Lath, gypsum board and gypsum panel product inspections shall be made after lathing, gypsum board and gypsum panel products, interior and exterior, are in place, but before any plastering is applied or gypsum board and gypsum panel product joints and fasteners are taped and finished. Dichas medidas contribuirían directamente a la mejora de la calidad de la construcción. The main anomalies liable to be detected in waterproofing systems are listed and classified.
