This document summarizes a study conducted by the Department of Civil Engineering at Mirpur University of Science and Technology on developing thermal insulation materials using different waste materials. The study examined using sunflower stalks, cotton waste, textile waste, stubble, epoxy, and gypsum to create insulation panels. Testing of the materials found that panels containing sunflower stalks, cotton waste, and epoxy had the lowest thermal conductivity coefficient of 0.1642 W/mK. Samples containing more air gaps also had lower heat transfer, with group Z having the best results. The document concludes that using waste materials to develop insulation can help reduce costs of heating and cooling while lowering environmental pollution.

Result:
A. Insulation materials made with Gypsum
1. Thermal conductivity coefficients
▪ The thermal conductivity coefficient of the insulation material
which was made with sunflower stalk fibres, the spongy parts of
sunflower stalks, cotton waste, textile waste, stubble fibres, and
epoxy was 0.1642 W/mK which is lower than many building material used.
A. Ultrasonic sound penetration velocity coefficient
• The ultrasonic sound velocity of the insulation material made with sunflower
stalk fibres, the spongy part of sunflower stalks, cotton waste, textile fibre
waste, stubble and epoxy was 0.9 km/s. This value is quite low compared to
other building materials. For example, this value is 1.6 1 km/s for brick.

Result:
A. Insulation materials made with Epoxy
1. Thermal conductivity coefficients
▪ The thermal conductivity coefficient of Sample A was Highest
and Z2 has lowest because of the content of material used and
pressure applied to material and porosity. The sample with the
lowest coefficient of conductivity,
0.0728 W/mK, was the Z2 sample.

Conclusion:
 In the houses, in which the panels made with gypsum, were applied,
the heating period was shorter and the cooling period was longer
compared to those of the houses in which those
panels were not used.
 When the pressure is increased, the heat transfer coefficients and the
unit weight increase also the thermal conductivity coefficients of the
materials depended on the fibre state, the amount of epoxy and
especially the pressure ratio. The optimum compression value was 7
bars.

Conclusion:
 Examples of low heat transfer coefficients were obtained in
group Z. The reason is the presence of more air gaps in the samples.
TS 805 EN 60155 requires a thermal conductivity coefficient of
lower than 0.1. In this case, N, S, P, and Z can be used
as insulating materials
 Waste materials, which cause environmental pollution is prevented,
and a satisfactory insulation material is produced entirely of organic
origin. The product is a candidate to be commercialized in the future.

Solutions:
 Thermal Insulation Material Reduce Heating Cost in winter
and Cooling Cost in Summer.
 Reduce CO2 Content In Atmosphere, So decrease Global
Warming.
 Use of Waste Material to overcome the Depletion of Natural
Resource.
 Using Waste in thermal Insulation material Reduce Soil
Contamination.
