What is खपरा (Khaprail (Tile))?

खपरैल (Khaprail), or छत टाइल (Chhat Tile), are traditional fired clay roofing tiles extensively used in Indic heritage architecture, particularly in regions like Karnataka, Kerala, and West Bengal. These ग्राम्या टाइल (Gramya Tile) are primarily terracotta, derived from clay deposits sourced from riverbeds and quarries across the Indian subcontinent. The chemical composition is dominated by silica, alumina, and iron oxides. Processing involves shaping, drying, and firing at temperatures between 800-1100°C, imparting compressive strength (15-30 MPa) and reducing water absorption (5-25%). Historically, the Chola Dynasty and Vijayanagara Empire utilized these tiles [2]. Physical properties include a density of 1800-2200 kg/m³ and thermal conductivity of 0.8-1.2 W/mK. Durability is affected by freeze-thaw cycles and biological growth. Conservation requires careful cleaning and replacement with tiles of similar composition and firing characteristics. कौलू (Kaulu) and नरिया (Nariya) are regional names. Restoration employs tools like tile nippers [1].
