Avoid unnecessary compression, as this can reduce acoustic and thermal performance. Final sound reduction depends on the complete wall or floor system, including board layers, sealing, isolation details and any flanking noise paths.\u003c\/p\u003e","brand":"Soundproofing King","offers":[{"title":"25mm","offer_id":53630002659667,"sku":null,"price":47.95,"currency_code":"GBP","in_stock":true},{"title":"50mm","offer_id":53630002757971,"sku":null,"price":47.95,"currency_code":"GBP","in_stock":true},{"title":"100mm","offer_id":53630002856275,"sku":null,"price":58.95,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1012\/0360\/7891\/files\/Screenshot2026-07-02233607.png?v=1783031836","url":"https:\/\/soundproofingking.co.uk\/products\/knauf-apr-acoustic-roll","provider":"Soundproofing King","version":"1.0","type":"link"}
