I probably should've asked this a long time ago but better late than never. When people talk about baffle height are they talking about the height of the baffle wall material or the loft? I know a general rule is about 2.5" of baffle height is usually good to around 20 degrees. So is that 2.5" of baffle material (minus seam allowance) or 2.5" of loft?
Thanks in advance for any replies!
