Thank you for your enquiry. The most effective way to insulate your music practice rooms would be to insulate the rooms by creating a room within a room with our resilient bar system used on the walls and ceiling. An approximate square metre price is £36.00 /sqm + VAT for materials. I have attached the link to our website.
