Abstract
This study investigates the use of utilizing recycled plastics, polypropylene (PP), high-density polyethylene (HDPE), and polyethylene terephthalate (PET) as alternative ceiling insulation materials. Motivated by escalating plastic pollution and the growing demand for sustainable construction practices, the research examines the thermal efficiency, durability, reliability, and user acceptability of recycled plastic-based Ceiling Plastic Insulator (CPI). A quasi-experimental research design was employed, incorporating controlled fabrication trials, thermal performance evaluation using a prototype housing model, long-term natural weathering exposure, and biological resistance testing against mold and pests. Additionally, survey data were gathered from homeowners, construction professionals, and government personnel to assess perceptions and willingness to adopt the CPI. Results indicate that among the tested materials, PP exhibited the most favorable thermal performance, recording the lowest surface temperature (34.8°C), followed by HDPE (36.1°C) and PET (39.7°C). All recycled plastics demonstrated high durability, showing no observable degradation, discoloration, or biological growth after nine months of outdoor exposure. Survey findings revealed strong positive acceptance, with 86.7% of respondents expressing willingness to use the CPI, primarily due to its potential for energy savings and environmental benefits. The study concludes that recycled plastic,s particularly PP and HDPE, present a viable, durable, and sustainable alternative for ceiling insulation applications. Their demonstrated thermal effectiveness, resistance to environmental and biological stressors, and high user acceptability support their integration into environmentally responsible building systems. Further research is recommended to enhance fabrication methods, assess large-scale performance, and evaluate long-term installation outcomes in real residential settings.
