One task that needs to be completed before adding more blown-in insulation is to install attic ventilation baffles. Once finished we’ll be able to completely cover the attic floor, which will give us the best performance from the new insulation.
Currently we have a reasonable amount of old blown-in insulation that (mostly) covers the attic floor. An exception is along the external walls near the top plate, which is evident in the summer when that part of the ceiling is noticeably warmer than along the interior. (See my FLIR ONE for iOS post for proof!)
With the baffles installed we’ll have an even thicker layer of insulation with more consistent coverage. We also won’t need to worry about blocking the soffit vents so that our attic can passively vent. Hopefully the top floor of our house will stay warmer in the winter and cooler in the summer as a result.
