The construction sector demand for thermal insulation materials is rising, to enhance building energy efficiency and indoor thermal comfort. While insulation materials like organic foams (EPS, XPS, PUR, PIR) or inorganic fibers (glass or rock wool) are widely used, there is a shift towards eco-friendly alternatives derived from agro-industrial waste. These sustainable options not only reduce operational energy consumption in buildings but also offset some of their own production energy requirements. Furthermore, using such sub-products as insulation materials presents an ecological advantage, contributing to CO2 sequestration and offering a greener choice in the construction industry. This paper presents the thermal properties of such insulating materials and compares their values with some of the commonly used insulation materials. The thermal conductivity of the materials was assessed using the λ-Meter EP500e, a guarded hot plate apparatus specialized for such measurements, using the instructions outlined in the SR EN 12667 standard, ensuring accuracy and compliance with established guidelines. The paper aims to elevate awareness about the potential of transforming what is currently viewed as agricultural waste into innovative and environmentally friendly building materials.
