Alrighty. We have a 24x24 metal building that has about 4” of spray In insulation on the walls/ceiling. it has a 12x12 roll up door and a walk in door. The air inside gets very stale and warm. even when we open the doors it still tells gross sometimes. We don’t have moisture issues but just a lack of fresh air. I’ve noticed when I climb a ladder, when I get to about 10’ the air temp changes. It’s like there’s a pocket of hot air that won’t move!!! would and exhaust fan in the rear help? With maybe an intake vent on front side? it has an 8’ fan that moves a little bit of air but I’d like to keep fresh air “circulating” if possible.
Also we have a 24x12 add on, uninsulated, it gets hot bein in the metal box, would adding a a vent in the rear and opening the roll up door help move air through? Or maybe some vents on the peak of the walls to let hot air out like an attic? There will eventually be a door installed to separate the two. Also there is a window on the side wall. I’ve attached some pics. Thanks

What about 24x24 windows next to flags on either side of beams?

We live in Houston TX. We don’t have a winter LOL. No but we have a small propane heater we use IF we need it.

some vents on the roof would be a good investment. will they eliminate your problem, idk. but i they will make it better, and maybe a lot.

 

[Nsmustang55ol]

Like a whirlybird bird?

 

[Nsmustang55ol]

Or some box vents

 

[Fix'n it]

like, whatever you find that would work and you like. lots of different kinds . the more the merrier

and if you put some down low on the walls, when the garage is closed up at night, you would still get airflow, and the night air would cool down the stuff inside

Similar to a house attic. Soffit vent to ridge vent.

basically, yes. the lower wall vents, even anywhere on the wall will work, if you don't like/want them low. but low would work better, ask me how i know.

How do you know

 

[Fix'n it]

ok, you asked for it

years ago i worked at a place. the bathroom, it had a typical bathroom vent fan in the ceiling, and a largish vent in the bottom of the door. one guy liked to "dump" at work . he would leave the door cracked and fan on, took hours to get the smell out, because the cracked door let air in the room at the top of the door. this vented the ceiling only. i told him to close the door. this caused air to come in at the floor. this air rose up through the room and out the vent fan, taking the stink with it. it only took minutes to clear the room.

I have a 70 x 30 steel building 18' feet high. I put in 24 x 24 inch windows at near the highest spot on each end. Brings in some great light and the with the windows open and a floor level window or two cracked. I get a nice exchange of air. Still gets hot, but it is fresh air.

that’s what I’m looking into!!! Perhaps a window in front and a fan in the rear

 

[Nsmustang55ol]

Also. I’m dealing with essentially 2 different buildings. Which isn’t a big deal. The add on has a window already, the hot air just needs a way out. Maybe putting some vents in the peaks
n each end?


As far as main building, I want to install a couple windows at normal level, then add a 24x24 window or just vents at peaks. becasue right now even with big door open and fan on, no air flow.

The company that made my building had a ridge vent as an option. I am conservative when it comes to putting holes in a roof. I had a house with shingles and a ridge vent it did not seem to be any better than not having the ridge vent. Attic was still crazy hot. I plan on spraying 8 inches of close cell foam on my roof then drywall. Should solve the problem, hopefully.
I have had several projects where heat was the problem. I have found that any powered ventilation is bound for failure. Had a powered roof vent controlled by a T-stat. Bought one with more ctm than I needed per the documents by the fan company. Hated the noise in my garage and when it failed I disconnected it and left it up there. Truthfully I do not remember any difference between running and not. Letting the heat rise and vent works for me. Maybe just get bigger windows. I bought 12v accuators which allows me to open and close the windows from the floor.

That’s the route we’re looking at, the main building, putting a window in the front and rear of shop up near the peak that can be open/closed from ground.
The small add on, problably put a loover style vent on rear, one with a built in bug screen. Also adding a 2nd window to add on because we worn out in there
