The coating process was performed according to the knife-over-roll method. Thermal measurements were carried out with two different principles to evaluate contact and radiant heat transfer according to JIS R 2618 (testing method for thermal conductivity of insulating fire bricks by hot wire) and EN ISO 6942 (protective clothing-protection against heat and fire-method of test: evaluation of materials and material assemblies when exposed to a source of radiant heat), respectively. Perlite coating enhanced the thermal insulation property of fabrics. The lowest thermal conductivity coefficient and heat transmission factor (0.088 W/mK and 26.83%) values were obtained at the maximum concentration with the biggest size perlite. With the increasing perlite concentration, solar transmittance values decreased for all particle sizes while solar reflectance values increased.eninfo:eu-repo/semantics/closedAccessParticle-sizeInsulationConductivityThicknessHeat transmission factorParticle sizesPerlite coatingsSolar reflectanceTextilesThermal conductivityScience & technologyPhysical sciencesReview000686940400001139410.1002/app.515431097-4628
