Questions
(1) Which rafter vents should I use? Lowes Hillsboro (2022 August 30) has many in stock, and their customer reviews are good. Home Depot is ship-to-store only, can't shop and examine materials. From Lowe's web page:
Durovent 22x48-in Raft(?) Vent - foamed polystyrene. (probably no)
ADO Products Rafter Vent with Baffle 24?x46-in. White emits/absorbs less infrared, better insulation. Baffle protects soffit vents.
polystyrene - one reviewer calls them "egg crate material", too fragile? (maybe no)
- I would prefer a vent shaped and colored like this but a more durable plastic.
proVent 22x48-in Rafter Vent. Black, may be more durable plastic, emits more infrared. Won't bend, won't keep old insulation out of soffit vents. (maybe yes)
- Are there commercial suppliers near Portland with more choices and better materials for rafter vents?
(2) Do bugs/bees/wasps build nests in the airspaces? I can inspect the long/skinny spaces with my borescope.
- Cleanout: If the plastic vents are stapled, removal will damage them. If lath-screws, I can remove and replace.
- I have adhesive plastic patches that I can put over the spots where I staple or screw. That will reduce strain and tears.
