Mill house insulation in Massachusetts is not really a question about which product to buy.
It is a question about what your house has become over time.
A mill-era home may have started as a compact worker cottage, a company-built duplex, a boarding house, a manager’s home, or a former industrial building later converted to apartments. It may have been repaired, re-sided, re-wired, re-plumbed, re-roofed, expanded, finished, and insulated in pieces by several owners across more than a century.
