Descriptionतृण (Trina), or thatch, encompassing छप्पर घास, फूस, पुवाल, and regional variants like புல் கூரை (Pul kūrai) [1], is a bio-based construction material prevalent in Indic heritage architecture. Derived from locally sourced grasses, reeds, or straw, its geological/biological origin dictates its chemical composition, primarily cellulose, hemicellulose, and lignin. Traditional processing involves drying and bundling, influencing its density (100-200 kg/m³) and thermal conductivity (0.05-0.08 W/mK). Historically used extensively during the Meitei Dynasty in Manipur and in Kerala and West Bengal, तृणमय छत सामग्री (thatched roofing material) provided insulation and weather protection. However, high water absorption and low fire resistance necessitate regular maintenance and replacement every 10-20 years. Conservation efforts for heritage sites incorporating तृण require skilled artisans employing traditional techniques. Durability is enhanced through proper thatching techniques and regular maintenance, crucial for preserving its historical significance.
