## \"The best sound insulation of the roof:\r\nAn effective solution to prevent noise pollution in urban environments\"\r\n\r\nSound insulation for the ceiling of **ursa** German brand with anti-knock technology\r\nWith the increase of urbanization and car life, noise pollution has become a big challenge. To deal with this challenge, the sound insulation of the roof stands out as an efficient solution in building construction.\r\n- These insulators prevent annoying noises from entering and leaving the work environment and homes.\r\n- Sound insulation of the roof plays an important role in absorbing and breaking sounds.\r\n\r\nThese insulators are composed of various materials such as ***polyethylene foam, egg comb, polyurethane foam spray, nano fibers*** and...\r\n\r\nBuying sound insulation requires attention to features\r\n_like sound absorption,\r\nSuccessful sound failure\r\neasy installation\r\nResistance to dust\r\nIt is antibacterial.\r\n\r\nTwo leading companies in Europe, **Isover of France and Ursa of Germany**, are recognized as industry leaders with advanced anti-knock materials to prevent impact sounds such as running.\r\n\r\nIn addition, sound insulation is divided into three categories **diffusers, sound absorbers and bass traps**. The most specialized solution to prevent noise pollution is the simultaneous use of all three types of sound insulation in building construction.\r\n\r\nGlass wool and stone wool are introduced as sound and thermal insulation.\r\nGlass wool with improved features such as\r\n• Recycled glass materials\r\n• Cost-effectiveness\r\n• Not combustible\r\n• Its low itching coefficient\r\n• Easy installation\r\nIt is noticable.\r\n\r\n### Disadvantages of glass wool insulation\r\n• If its quality is low, it causes itching.\r\n• Its installation requires protective equipment such as masks and special glasses\r\n\r\n### of the benefits of polyester insulation\r\n\r\n• Very durable\r\n• It is not allergenic.\r\n• It is non-toxic.\r\n• Not irritating.\r\n•Environmentally friendly.\r\n\r\n### of the disadvantages of polyester insulation\r\n• It has a higher price than glass wool.\r\n• It melts after being exposed to heat and flame.\r\n• Although it has a higher price than glass wool.\r\n\r\n### Advantages of cellulose insulation\r\n\r\nReducing paper and cardboard waste.\r\n• Cheaper than glass wool.\r\n• It causes little itching compared to other traditional fiberglass.\r\n\r\n### Disadvantages of cellulose insulation\r\n\r\nIf it is applied in a dry form, it will hang and precipitate after the passage of time.\r\nCompared to other sound insulation, it absorbs moisture easily.\r\n\r\nChoosing the right insulation and paying attention to the positive and negative points of each of them is important for the construction and renovation of houses.\r\n[Ceiling sound insulation] (https://idehpoyan.com/%25d8%25b9%25d8%25a7%25db%258c%25d9%2582-%25d8%25b5%25d9%2588%25d8%25aa%25db%258c-%25d8 %25b3%25d9%2582%25d9%2581-%25da%2586%25db%258c%25d8%25b3%25d8%25aa%25d8%259f/)
