The more you know the betterCan you describe what an old roundhouse would be like? Layout, look etcAlso what were the trains called back then? The ones with the big black pipe thing on frontI am train-illiterate as you can see.
The soffit material isn't suppose to let air through, but the soffit installation is nowhere near airtightThey must have messed up by putting pieces of the soffit up against the vents in the wood instead of leaving a gap for the air to get through You can just look for some good looking vent covers that you can cover the holes you're going to cut in the soffit with.
You can go back and do it anyway you want toMy50year old house has a mesh screen on the pereterRemeber you need ridge vents to let the heat excape that's what your doing is circating the hot airI had hardiblank and wood then those mesh vents cutI live n south texas.
I dont understand? if they used the vented soffet why wont water run through it?The sections have thousands of small holes the biggest allowable size to keep out bugs
Yes you can but be careful cutting out the hole in the sofit to make sure that the vents you fit are the right size .
