Upgraded my sawmill shed with spray foam
« on: June 09, 2019, 01:47:11 PM »
When we bought the farm last fall the building that would house the mill had a metal roof and was open on the end and partially on the side.  Other than cleaning out the area the biggest problem I had was the insulation. The building had this paper thing insulation that was tore in most places and falling off every time I tried to repair it. I made the call last month to get closed cell spray foam installed.  The contractor showed up last week and did the whole building in one day. The building is 20x70, 20x30 is the wood shop  and the rest 20x40 is the sawmill part. They sprayed 1 1/2 thick closed cell and got the job done in about 6 hours.  The biggest difference so far is the building is now a lot cooler and in the morning I have no more condensation dripping down on the LT40.  Very happy with this decision and would encourage anyone with a condensation issue that this will help your problem.  I also had a few small leaky/drips in the ceiling around screw head that attached the metal to the trusses. This also fixed that problem also.  The cost was $2500.00 and they also did the gable ends also. I have two barns to build here in the future and both will get this same treatment.

Interesting how the metal pattern telegraphs through the foam with all the layers he put on there.  They say it will stop the leak but I'd be a little concerned that the water is still getting through the roof to the trusses.  I'd do something from the top to seal the screws like a dab of tar or some caulk.  Or maybe remove and replace one at a time with new ones with the rubber washers.

The next thing you know, Nathan is going to start shaping the foam, adding chicken wire, and spraying concrete to make it look like a natural cave!
Anything someone can design, I can sure figure out how to fix!
If I say it\\\\\\\'s going to take so long, multiply that by at least 3!

Very nice, 
You guys in the south have it easy with a light building. Up here the snow would crush the thing.
I hope it does all you want it to do.

The water was probably coming from condensation.  Those lightweight metal buildings aren't ventilated at the top so all of the moisture is trapped.  One of my neighbors has one that is enclosed on three sides and has a dirt floor.  It is basically useless as it rains from the condensation.  The spray foam will prevent the temperature gradient and alleviate the condensation.
