The warmer air on one outer side of the wall causes water to build up along the colder inner side.
Moisture on basement walls behind insulation.
But excess condensation can lead to a host of problems.
Ran all of my electrical and plumbing.
From there your basement can become a breeding ground for.
With this approach you insulate exposed duct work pipes and walls anywhere that water tends to condense.
Not to be confused with a vapor barrier which is placed on the warm side of the wall just in front of the insulation and behind the drywall a moisture barrier goes against the basement wall.
In the process i learned that there is vapour barrier on both sides of the insulation trapping moisture of course.
Liquid water from rain or ground water.
The moisture will get the insulation wet and reduce its effectiveness.
Fortunately you can get rid of excess condensation on your walls and control excess moisture in your home.
Basement water problems are solvable but there is a cost to doing it right.
I know there should only be vapour barrier on one side in my view the outside.
Some condensation is harmless even normal.
If you desire you can add some more batt insulation in the studs of the wall at this point.
Insulating the places where condensation builds up can also help to eliminate moisture.
To correct basement moisture problems it s necessary to understand where the water is coming from and what mechanisms permit it to enter the basement.
Condensation in your finished basement can build up in insulation and the wood framing and even pool on the floor behind finished walls.
I found mold behind my baseboards and have removed bottom sections if drywall to gauge the extent of the problem.
Another approach to the condensation problem is to reduce the extent to which moist air contacts cool surfaces where it can condense.
I found the basement warmer after doing this than the builders r 12 pink.
This is especially true in tightly fitted walls where little air travels.
The most common cause of condensation on your walls is excess moisture inside your home.
Then i framed the outside wall of my rooms in the basement.
This is the 2 r 10.
Then using pl300 i installed 2x8 dow styrofoam.
Covering those places such as walls pipes and ducts with insulation will help keep warm air from coming in contact with the cool surfaces thus preventing condensation.
Condensation behind the vapour barrier is formed when the warm moist air of your basement comes into contact with the cooler basement walls.
