EXPLORING THE POTENTIAL OF GLUED AND CROSS-LAMINATED TIMBER IN SUSTAINABLE CONSTRUCTION

Abstract

This article presents an analysis of the properties of glued laminated timber (GLT) and cross-laminated timber (CLT), solutions developed for the structural use of wood. The aim of this work is to evaluate the sustainability, cost-effectiveness, and resilience of these materials in construction. For this purpose, a literature review of studies and research in the field was conducted. The results indicate that the use of wood in its laminated form has advantages over other conventional materials, especially regarding sustainability and resilience. Wood is a renewable resource with a positive carbon footprint, and its use in construction can contribute to reducing environmental impact. In addition, GLT and CLT have high mechanical strength and durability, making them a viable alternative to the use of concrete and steel in some situations. Regarding costs, the results found are equivalent between wood and concrete in some buildings up to five stories. However, laminated timber may have higher prices compared to other materials, but construction time is usually faster due to the use of prefabricated systems, which can result in significant savings in total project costs. The main challenge identified for the growth and implementation of these materials is the short development time and the need for greater dissemination of research and practical results in the field. It is important that government agencies, universities, and industries work together to promote research and development of new materials and construction technologies that can help drive the adoption of laminated timber as a sustainable and cost-effective building material.In summary, the analysis carried out in this work indicates that the use of glued laminated timber (GLT) and cross-laminated timber (CLT) in constructions can be a sustainable option with equivalent results in terms of cost compared to other conventional materials. However, more investment in research and dissemination is needed to drive the adoption of these materials in construction.
