Natural fibers are easily accessible, biodegradable, and safe for human and animal health. The banana is a tropical plant and one of the earth's most widely cultivated and consumed fruits. The leaves and trunk are thrown following the removal of the bananas. Cellulose is one of the most eco-friendly forms of insulation, and it is also one of the most fireresistant forms of insulation. Research into the thermal insulating properties of plant-based lignocellulose materials has indicated their potential for use in building thermal insulation. At ideal density, the thermal conductivity of these materials fell within the range for use as thermal insulation in buildings. Banana fiber is a viable option for thermal insulation due to its length. Now, this lookup strives to use organic material to be incorporated with paint as a thermal insulator. Modernization commenced, and paint was made with hazardous chemicals. However, this study shows that pulverized banana fibers mixed with white elastomeric paint can be thermal insulators in dwelling walls. The experiment consisted of four samples; Samples 1, 2, 3, and 4. The four setups are placed outside the house where sunlight is easily absorbed. The digital thermometer was placed inside the cubed hollow blocks to get the interior temperature. The temperature was recorded after 1 hour of exposure to heat for twenty-four hours every hour and re-recorded after three weeks for four days. Results showed that Sample 4 had the most significant effect in the thermal resistivity test, and concentrations of pulverized banana fiber had no significant impact on the adhesion tape test.
