The Application axis of Plasterboard segmentation distinguishes four primary end‑use categories: residential construction, commercial construction, industrial facilities, and infrastructure projects. Residential construction—encompassing new housing, multi‑family units, and interior renovations—accounts for the largest share, driven by steady population growth and building‑code mandates for fire safety and acoustic performance. Commercial construction includes office towers, retail spaces, and hospitality venues, where demand is moderated by corporate real‑estate cycles and the adoption of green‑building certifications that favor lightweight, recyclable board systems. Industrial facilities—such as factories and warehouses—require boards with enhanced load‑bearing and moisture‑resistance, contributing a smaller yet stable portion of the market. Infrastructure projects, covering schools, hospitals, and transport terminals, represent a niche segment whose growth is tied to public‑sector capital expenditure. Collectively, these application sub‑segments define the overall market size, with residential contributing roughly 55 % of total volume, commercial 30 %, industrial 10 %, and infrastructure 5 %.
