Bio-based and natural building materials can help reduce the environmental impact of the construction industry. This study evaluated the performance of giant reed as a thermal insulation material in experimental research. Reed was chosen for its availability and relevance to Portuguese vernacular architecture. The study assessed the origin, physical characteristics, and durability aspects of the reed. The results showed that reed boards performed well as thermal insulation material, regardless of their origin, with denser boards yielding better results. However, mold growth was observed under favorable moisture conditions.
Bio-based and natural building materials can support the building sector to reduce its environmental impact. In this study, experimental research was developed to evaluate the performance of giant reed when used as a building thermal insulation. Reed was chosen due to its high availability and close relationship to Portuguese vernacular architecture. The role of the reed's origin in this context, its physical characteristics and its durability aspects were evaluated. The results showed that the performance of the reed boards was compatible with their use as a thermal insulation material, regardless of the reed's origin. Denser boards showed better results. Under the favourable conditions related to the reed's water content, mould growth could occur.
