Abstract

This research investigates the thermal performance of commonly used greenhouse construction materials fiberglass and polyurethane (PU) foam sandwich panels in the context of urban agriculture. Precisely controlled-environment agriculture is technically the focus of greenhouses, especially in urban settings where thermal regulation is vital for plant health. The study excludes HVAC systems to focus solely on the material properties influencing heat gain and loss. Through a combination of simulation (SOLIDWORKS) and experimental modeling, the thermal insulation efficiency of the materials is evaluated under Malaysian climatic conditions. The findings aim to guide sustainable and cost-effective material selection, reducing reliance on mechanical temperature control and promoting energy-efficient urban agriculture infrastructure. On that note, the research has concluded that PU Foam sandwich panels are better for thermal insulation than fiberglass even under heavy rain conditions which proves properties of versatility, durability and thermally in favor of PU Foam
