Customer Questions
My sound engineer has advised i need 150mm of RW5, but the thickest I can find is 100mm?
The Rockwool RW5 can be combined to create 150mm, either using two lots of 75mm or a 50mm and a 100mm. This should then be installed in a 'brick pattern' so to minimise any gaps between the layers.
