Hi all, I have just been out to the garage, which is attached to the house & noticed that the lower half of my bus was covered in condensation. I have double glazed doors front & back and new job sectional garage doors which do have a good deal. Is this down to a lack of air circulation? Do i need to add some air bricks? I also have 2 little double glazed windows at the front but they have no openers. Thx
I've a concrete sectional garage and working in there today was almost like been outside in the drizzle! How can you get ventilation in this type of garage......is expanding foam in the roof corrugations a bad idea ?
Just get a through flow , I have carport with sides and front canvas but a six inch gap front and side low level with vent grille at top .
Tnx.. not sure if it would help covering the bus? My garage is brick with a wooden felted roof. I don't think there are any air bricks so maybe I need to put a couple in.
same as my garage mess the lenght off the side off the roof roof over hangs then garage door is at an angle as the fllor runs down hill allowing air to free flow
I’d say more ventilation as well. But...has been very humid today. Our garage has cavity walls, and it’s still damp inside...
Just a thought, has the outside temperature risen quickly where you are, thermal inertia in the steel of the van can leave it cold when the air warms up, as a cold spot any humidity in the air will settle there, in that case it may not be a big on-going issue, a cheap hygrometer may show if there is higher than normal humidity in the garage.
Just ordered a new roller garage door to get van in easier......no way I'm cutting vent holes in it !
you can mount the door with a 3 inch gap along the bottom let air free flow and won t look out of place ill get pic of mine tomorrow blowing a gale at minute
In my previous house, when it rained water ran down the inside walls after soaking the brickwork. I painted the outer surface with silicone treatment and the problem went away. If your garage has very little air flow then you could use a dehumidifier - the mains powered kind with either a drain hose or a container for the water. Set it up to drain outside and leave it running. They blow dry sightly warm air. A neighbour has a heated insulated sealed garage for his Triumph TR2 and old motorbike with a nice roller shutter that goes down onto a rubber seal as a door.
Have a very very good look around and find the cause before you start doing things that may increase it. The formula for condensation is called HIVE, it’s heating versus insulation versus ventilation versus excess moisture. If one of these is out of wack then condensation can run riot. There are a few other things that can throw a curved ball but usually the worstest is thermal conductivity, metal is a git for that, as in alloy doors and windows, because it transmits the cold into the area allowing warm air to condense way too easily, alloy ladders are also great at this, we’ve all grabbed an alloy ladder on a cold day. Concrete is a swine too especially lintels and concrete lintels with steel in are some of the worst, ask anyone with Finlocks. A remote thermometer with a laser will guide you as to where the real cold bits are. Mike, that’s a possibility usually when an extension has been built or a conservatory maybe even a garage and the formerly outside skin is now inside and wet which it is designed to do. A cavity wall tray is the long term answer however Thompson’s or other clear silicone can stop the skin above becoming sodden and trickling down to the lower levels. Might last two years or might last ten or even fifteen, just depends on the prevailing weather. In Spain it would last forever Ozziedog,,,,,,,,,,bit of a mine field
This may be why my garage doesn't seem to suffer from condensation. Instead I get a constant barrage of leaves blowing in under the gap.
Well, what a difference a day makes.....dry as a bone in the garage today......must have been an unusual set of weather conditions yesterday.
Sure the van hasn't drunk it all ?? On a serious note the moisture might have disappeared but the problem hasn't... Sent from my SM-A320FL using Tapatalk
That garage was in a external block. Single layer of brick with piers, the wet wall was facing southwest.
