Always air sealing before adding insulation. If you want to get the advertised R-Value, you need to seal and baffle your attic before insulating. We have a great example here of before and after!

As always we will tell you air seal before you blow in your insulation in the attic space of your home! This saves money, disconnects your attic space from your living space.. and that adds to comfort and makes your home much more cozy!
