This project aims to replace the use of conventional siding materials and systems with a more efficient and environment-friendly alternative made out of recycled Polyethylene terephthalate plastic (PET). The proposed system will also act as a highly efficient thermal and moisture barrier by drastically reducing thermal bridging and the amount of moisture that infiltrates the exterior building envelope which often creates mold problems for the homeowners. This system will leverage the unique mechanical properties of PET such as resistance to weathering, durability, fire resistance, and its abundance to create a cost-efficient alternative in which its benefits can be enjoyed by stakeholders across the entire supply chain. The product will undergo various testing and enhancements to accommodate its use in residential structures. Additives will be combined with recycled plastic until an optimum ratio is achieved. These ratios will be developed using WUFI and THERM software to predict and model the effect of each additive on the final integrity of the new system. In addition, the siding systems will have an innovative connection design that is easy to install and can accommodate a wide range of insulation materials and finishing surfaces. Continuous communication will be maintained with potential stakeholders during and after the designing and manufacturing phase of the siding system. Homeowners, contractors, engineers, architects, and additional stakeholders will play a crucial role in providing constructive criticism and feedback. Stakeholders’ feedback will be used to make the necessary adjustments and iterations to the new siding system, to ensure smooth market entry and customer acceptance.
