It features a central high-density acoustic membrane with an integrated anti-creep layer, enclosed between foil-faced glass fibre insulation.\u003c\/p\u003e\n\u003cp\u003eThis free-hanging solution helps address flanking paths in suspended ceiling systems and is used in both new construction and retrofit applications. Its surface mass of 10kg\/m² and composite build enables a standalone airborne sound reduction of 33dB Rw (tested to BS EN ISO 140-3:1995). The product also achieves a reaction to fire classification of B-s1,d0 to EN 13501-1.\u003c\/p\u003e\n\u003cp\u003eThe flexible composition allows for easy handling and fitting in constrained ceiling void spaces.\u003c\/p\u003e","brand":"Siderise","offers":[{"title":"Default Title","offer_id":51152366305627,"sku":"51152366305627","price":228.9,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0822\/7763\/0299\/files\/CB10.VMain.jpg?v=1754899865","url":"https:\/\/www.nationalinsulationsupplies.com\/products\/siderise-cbx-flexible-acoustic-void-barrier-for-suspended-ceiling-2m-x-1-2m-x-40mm","provider":"National Insulation Supplies","version":"1.0","type":"link"}
