The sound-absorbing properties are certified based on measurements carried out in the laboratories of the Fraunhofer Institute in Germany, in accordance with EN 14366. The use of sound-absorbing clamps is recommended.  <br \/> The fire behavior classification of the piping in accordance with DIN 4102-1 is class B1. When passing through ceilings, we recommend using fire collars as a flame-spread protection measure.<br \/> To reduce the noise level of indoor sewer systems, the following are recommended:<br \/> \u2022 Choosing a pipe and fittings system with good sound-absorbing properties;<br \/> \u2022 Proper system design;<br \/> \u2022 Correct installation of the system using suitable products. <\/p>\n","protected":false},"excerpt":{"rendered":"<p>Used in indoor sewer installations for draining domestic wastewater in [&hellip;]<\/p>\n","protected":false},"featured_media":97737,"template":"","meta":{"inline_featured_image":false,"wds_primary_product_brand":0,"wds_primary_product_cat":0},"product_brand":[],"product_cat":[8131],"product_tag":[],"class_list":{"0":"post-130845","1":"product","2":"type-product","3":"status-publish","4":"has-post-thumbnail","6":"product_cat-sound-absorbing-pp-pipes","8":"first","9":"instock","10":"shipping-taxable","11":"product-type-simple"},"yoast_head":"<!-- This site is optimized with the Yoast SEO Premium plugin v27.2 (Yoast SEO v27.2) -
