Grah8m Posted October 29, 2020 Share Posted October 29, 2020 What is actual material used for "sound barrier for ventilation ..." (ref: EAN 4010184083108 ) ?. Oddly the cost for a very small amount to do a 100mm vent, can be about £20. But what is it made of to justify the expense ?. Link to comment Share on other sites More sharing options...
