| Description | Glūlām Kāṣṭha (ग्लू-लैमिनेटेड काष्ठ), or Glulam Timber, is an engineered wood product increasingly utilized in modern Indic architecture, offering an alternative to traditional solid timber members [1]. Its composition involves bonding layers of *kāṣṭha* (काष्ठ, wood) using durable adhesives. Density ranges from 400-700 kg/m³, while bending strength is typically 40-70 MPa, and the modulus of elasticity is 10-14 GPa. Sourcing timber from sustainable *vana* (वन, forests) across the Indian subcontinent is crucial. While not historically prevalent in ancient structures, its application in contemporary temple construction and community halls reflects evolving building practices. Fire resistance can be enhanced through chemical treatments. Conservation efforts focus on adhesive stability and preventing biological degradation (*kṣaya*, क्षय). The material's durability is paramount, especially when integrated with existing heritage structures during restoration. Its use allows for long-span structural elements, such as roof beams and arches, previously unattainable with traditional *lakdi ka lattha* (लकड़ी का लट्ठ, wooden log) construction [2]. |
