The polyurethane foam and rice straw composite proved to have a higher efficiency than the pure polyurethane foam through the insulation properties, mechanical properties and the overall cost. The thermal conductivity of this new composite is 12% lower than that of the polyurethane foam with thickness reduction of also 12%. The advantage of this sample is also using a waste such as rice straw which is easily available for free. Rice straw is a good selection as a filler due to its low thermal conductivity which improves the material insulating properties. Consequently, this results in reducing the cost of insulation by 28.35%.\u003c\/p\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9786139445035\"\u003e\u003ch3\u003e\u003c\/h3\u003e\u003c\/div\u003e","brand":"Libri","offers":[{"title":"Softcover - 9786139445035","offer_id":39464349892701,"sku":"9786139445035","price":54.9,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/c9777b6e-228f-4578-a5d9-5849826f7435.jpg?v=1769496594","url":"https:\/\/shop.autorenwelt.de\/products\/roof-insulating-material-based-on-rice-straw-and-inexpensive-polymers-von-reem-nasser-m-a-radwan-hany-a-elazab","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
