Conclusion

Test Summary

Overall analysis of our test phase showed the tubes to maintain structural integrity under compression. Cardboard provided adequate bracing and barrier to the water with no penetration of moisture to the inside of the shelter. Although cardboard is inadequate as a fire rated material alone, insulators such as Ceramiboard incorporate a layer of ceramic fibres in between cardboard and could be investigated as a fire rated material. The PVA glue used as a protective sealant in this simulation failed under the application water sooner than expected; despite Westborough Cardboard School using the substance in their manufacturing of cardboard materials, they applied an organic polymeric coating to protect its vulnerable underlying materials. The application of PVA glue for this simulation was due to it being affordable and accessible, and believed it would provide a reasonable level of protection to the cardboard. We however acknowledge the use of other organic applied sealants would be a sustainable alternative.
