Gaz means you cant really have it insulated but still introduce cold air inside from outside as this will still cause it to condense and drip...insulate and close all gaps..
What gaps are you referring to? The action of opening and closing the door would introduce cold air inside.
The only gaps that I can see are the garage door, and the hole for the extractor. There's not much I can do about the door, as putting in a new one will mean doing the roof as well. It's a lot of work and is simply not worth it at this point in time.
Everything i've read about condensation in garages states that warm air coming in will condense on the cold surfaces. This is mainly the roof. If I insulate the roof it will prevent warm air from coming into contact with it.
not pocking fun just being blunt honest here
to stop any heat getting close to your roof you need a good amount of insulation and seal it well
yes you can use the cold roof method above your insulation but thickness is really important get any heat near that cement roof and it will drip and 1/2" insulation is not enough you need more of it
we use the cold roof method on roofs but the ceilings are well insulated to stop that heat getting anywhere into the roof void of an apex roof, flat roof or single slope roof
fitting any type of heater weather electrc or wood will heat up the ceiling well enough to pass the heat into the roof void
Yes I plan on sealing it well. I don't see how warm air will get to it when there's an open cavity in between the insulation and the roof. And besides, if it does drip, it will only drip onto the insulation and run down. If this is sealed well I can't see it being a problem.
As stated earlier, very occasionally do I use the garage in the winter months, but i'll refer back to my comment above... so what if it drips from the roof onto the insulation?
I'm open to criticism and I like to learn, so please don't think i'm being obtuse. Tell me why i'm wrong.
