frost inside

[duderjay]

Hey guys on my new garage I get some frost in some areas along the base of the walls.

Even with heat in the garage.

I have siding tyvek wrap insulation vapour barrier and drywall. I am also considering putting in some simple baseboards sealed with silicone but I wont do it yet until some discussion of this frost issue

what do you guys think

thanks in advance

Um Jay I dont know how to tell you this but uh duuuuuuuuude you live in Canada Eh they call it the great white north . Ok being serious it sounds like the sides of your foundation dont have any insulation .

Simple - you need an exhaust fan running to pull the moist air out of your shop. The only way frost forms is from humidity. I live in SK - as cold/colder than AB and do not get ANY frost on a similar set up.....AB is more humid: you guys are getting WAY more snow than us (haha!!). I would say have an exhaust fan hooked up to a reostat. It turns it on at a set humidty. Keep it below 40-50% rel. humidity and no-more frost.

Try a dehumidafier.

What kind of heat? Any heat that uses combustion, also creates water as a byproduct. The more you heat, the more water you create in the building.
I'm betting that if you don't heat, you also won't have any frost inside the building.

ok theres a couple of spots that I can feel cold air coming in. Its just a slab. Guess what I'll do is seal up where I think the cold air is coming in. Then I'll put in my base boards and silicone em in place.

Thats what I was kind of thinking of doing.

Theres bound to be humidity with the wife runing her car in and out of there non stop with snow on it. It use to be a lot worse with the other heater that was in thereusing out side air for combustion and just circulating the moinst air in there..

I'll go back to what I said before - you need air movement - which is what an exhaust fan provides. Sealing up the drafts is good for insulating value, but can make the condenstion even worse. Your wifes wet car is the source of the water and a fan will help the air movememnt - but only if you have a source of air coming in. Even sealed homes are not completely sealed. Air comes in from an air make up, kitchen exhaust, dryer vents, chimney, etc.
A dehumidifier pulls water out of the air, but then pools it in the machine - you still have to empty it.
I have the same situatin in my 2 car. I just turn a window fan on when the cars are wet.

e-tek has the right idea.
Wast a little heat to get rid of the moisture.
