Frequently Asked Question
How are insulation baffles installed?
You should start by preparing your attic space. First, check and clear the area where the baffles will be installed, removing any old insulation from the edges if necessary. For more information, check out our guide https://www.greenattic.com/blogs/how-to-install-attic-baffles
