The construction sector continues to adapt to the challenges posed by climate change. Architects and engineers aim to build sustainable, energy, resource, and cost‐efficient structures by increasingly using bio‐based building materials. However, fire safety has always been a significant concern for timber building construction internationally. The objective of the study presented in this article is to document fire hazards of compressed straw when used as thermal and acoustic insulation within wood‐framed building assemblies. Three densities of compressed straw (75, 125, and 175 kg/m³) were selected and their combustion and thermal responses were evaluated at various scales, in attempt to define the optimal density considering various factors. The performance of the straw was also compared with commercially available insulation materials and then tested under exposure to severe heating in medium‐scale wood‐framed assemblies to evaluate the impacts of the straw as compared with a noncombustible insulation. The compressed straw with a density of 75 kg/m³ was found to have the best behavior with respect to both reactions to fire and insulation properties. The results suggest that compressed may have similar or better behavior under the heating conditions investigated when compared to a commercially available combustible insulation material. The use of this material as a primary insulation in a buildings is considered manageable by thoughtful design, construction, and building use without unduly increasing risks associated with fire.

压缩稻草作为木结构隔热材料的着火危险

建筑行业继续适应气候变化带来的挑战。建筑师和工程师的目标是通过越来越多地使用生物基建筑材料来构建可持续的，能源，资源和成本效益高的结构。然而，消防安全一直是国际上木材建筑施工的重要关注点。本文介绍的研究目的是记录压缩秸秆在木结构建筑组件中用作隔热和隔音时的火灾隐患。三种密度的压缩秸秆（75、125和175 kg / m ³选择），并在各种规模下评估其燃烧和热响应，以尝试考虑各种因素来定义最佳密度。还将秸秆的性能与市场上可买到的隔热材料进行了比较，然后在中等规模的木结构组件中经受剧烈加热，进行了测试，以评估秸秆与不燃性隔热材料的影响。压缩秸秆，密度为75 kg / m ³在对火和绝缘性能的反应方面，发现具有最佳性能。结果表明，与市售可燃绝缘材料相比，压缩材料在研究的加热条件下可能具有相似或更好的性能。通过周密的设计，建造和建筑物使用，可以将这种材料用作建筑物的主要隔热材料，而又不会过度增加火灾的风险。
