Gypsum wallboard

Drywall, also known as wallboard, plasterboard or gypsum board, is a popular building material made from gypsum and used as an alternative to application of wet plaster to form walls and ceilings.

However, uncontrolled excess moisture in buildings (damp areas like bathroom or kitchen, wet seasons, high relative humidities, leaks, …) is a common problem that can lead to fungal growth, resulting in unpleasant odors, stains, and premature biodeterioration of construction materials.

A study (Andersen et al., Indoor Air, 2017, 27(1):6-12) has shown that fungal species are often already embedded in the wallboard, presumably in the paper/carton cardboard layer surrounding the gypsum core, before the panels reach the construction site. Introducing PYRION^® antimicrobials (Zinc PYRION^™ and Sodium PYRION^™) during the manufacturing of wallboard, both in the paper layer as and in the gypsum core, may protect your products during the entire service life in people’s houses, avoiding such unpleasant odors and stains, and protecting residents from exposure to indoor mold.
