Rob I read that the Castleblock system is insulated. What about noise reduction? How effective is it at blocking out sound, as in our least liked neighbor, those damned frogs?!! Our stick built is 6" thick with R-19 insulation. It is quiet as a mouse with the DP windows closed. We are trying to find the most noise reducing materials for an addition. Thank-you so much for this website, it is an absolute God send, especially when we really need to know what is happening in our own backyard
