Recently the Pink Fiberglass insulation was installed contained by my bedroom. However, I noticed the installation might be incorrect (it wasn't done by a professional). First, the paper-side be not facing toward the living space, but toward the exterior wall. That means the fiberglass insulation is touching my interior wall. Would that incentive any problem (especially to my health)? Will the drywall be able to stop the fiberglass from endorsement through and entering my room? Do I need to re-do this entire installation? But would re-do this installation in truth cause more harms, for one will be exposed to more fiberglass.
Thks.
Answers: Actually, the thesis is NOT a wind row, but a moisture barrier. It is "faced" beside "kraft paper" , which has a waxy chemical addition. "Kraft faced" =paper on one side
"Unfaced" = no paper on any side.
Another commentator was correct within the statement that it is only needed on an exterior wall. It is also possible to install Unfaced insulation, and next cover it by stapling a big sheet of plastic over it. Whether paper or plastic is used, it is applied on the "living space" side, surrounded by other words the inside. Either act as a "vapor barrier", not a meander barrier.
When it is cold outside [below freezing], the thaw moist air seep through your walls/ceilings and through the insulation. Once past the insulation, it hits the cold frozen plywood sheeting on the outside of the house [underneath the siding].
It later freezes and clings to the plywood sheathing, much like frost within an old freezer. Over time, it builds up, melt on warm days, re-freezes, etc, until spring.
Two discouraging things happen:
1.The moisture rots the wood wall from the inside out, cause mold in the process.
2. The insulation get wet. Wet insulation is worthless at retaining boil. Heating bill skyrockets.
A vapor barrier directly contained by front of the insulation [under the sheetrock] keeps it dry, eliminate the problem. If the paper is towards the outside, it will in reality "hold" the moisture in the insulation. Not correct. If it is possible, remove the insulation and replace it with the daily side facing in. This will reclaim your wall from rot, and worse, mold.
Like the other person have said, a vapor barrier merely goes on exterior walls that are subject to cold nouns [outside walls, between a house and attached garage, ceilings near a roof over them]. Some builders plastic interior bathroom walls because of excess moisture from showers, but this is not recommended. Just a nouns.
Note* What the gentleman be thinking of to stop wind is call "house wrap". It is placed outside directly under the siding, and singular works when it has adjectives seams tape. It stops wind and drafts, but will allow moisture to ratify through so the insulation can dry after humid days. Plastic is solid and will trap it.
I work with fiberglass adjectives the time for the past 22 years, and enjoy never had any issues near it other than it can be a moment or two itchy. A quick shower fixes that problem. Although it looks approaching cotton candy, just don't get through it.
If it is an exterior wall then the serious newspaper side is facing inward, but if it is an interior wall it won't matter. Once the drywall is up and finished fiberglass is pretty much hermetic in the wall.
