Building in northern Canada, ventilated attic.
The framer did his own baffles made of plywood, however he installed baffles every 4 rafter and blocked the other cavities with plywood.
• Is this bad? should I do remove the ply wood and installed some pre-made baffles?
• if no, should I try to insulate the cavities with spray foam ( I got a couple of froth pak lying around) – I think it would be best if no cold air goes through the middle (or side) of the loose insulation, but only comes via the baffles.
Here is a picture.
