How to install paper faced insulation

If I use faced insulation should the paper go towards the outside of the house or the inside? The insulation is against the wall NOT towards the first floor. Or, should I use unfaced? My thoughts were I would use faced so there would be a barrier for moisture coming from the outside wall. Can I just remove all doubt and potential moisture and go with unfaced and get a good barrier of insulation? Ken, On basement walls, the vapor barrier facing on insulation should be toward the outside of the house.

It is also a fire hazard to have the paper visible, as the treated paper will contribute significantly to a fire. Thank you Ben and Tim! Tim, I had read that paper faced insulation must be covered appropriately because of the potential fire hazzard.

Thanks for giving that important reminder!!! My main concern are the hot water pipes. Should i peel the paper off and safely install over it? Make sure you get the right size for your pipes. I have always used unfaced insulation between two heated areas. It does not make much sense only it cuts down on sound a little, I use R30 with steel wire supports, Richard. This information on fiberglass and the installation of insulation is so important, thank you for sharing your advice for everyone to read.

I worked for an insulation company for many years, and I was surprised at how many times people would install their fiberglass insulation in the wrong direction. There was not enough ventalation in our crawl which has caused the insulation to hang. Is there a fix for that rather than having to replace it all?

I could see the paper back as soon as I took out the wall. My question is was it properly installed? Can I just put additional insulation on top of the old one? I need your advise. Thank you. My husband is putting up fiberglass insulation in his barn and was wondering which way it should face if he is using it in the ceiling? I live in south Georgia, near Savannah; should the facing in my crawl space insulation face the floor or the ground?

I am planing to used the attic on top of the garage. I wonder what type of insulation I should use in the ceiling, and if it is necessary to insulate the floor, and what kind of insulation I should use? I have a garage door and area to store a boat in my basement like a walk out in the winter months.

I live in MN. The floor above this space gets cold in the winter. Although there is heat in the basement, this area can reach 45 degrees in really cold months, due to the fact that there is a garage door.

I was thinking of insulating this area and using insulation without paper because of pipes and electrical work in the cavities. Does this make sense? Also, can I use plastic to cover this insulation or use something else? About 20 years ago, I installed fiberglass batting insulation using wire strips in my crawlspace floor joists with the paper facing the crawlspace dirt floor as I was instructed by the supplier. I have always had problems with carpeting wrinkling in my home and am now wondering if the batting is trapping moisture and should have been installed with the paper facing the floor of the home.

I am about to replace the subfloor in my double wide and plan on replacing the insulation with R Should I use no faced or faced and if I use faced which way should it face. I live in Charlotte, NC. Well, insulation is certainly confusing. I just finished my basement, and the inspector told me that I have the insulation on my outside walls those along the concrete facing the wrong way. He told me the paper face should face towards the cement wall side. Do I does he have it right. Thank You, Richard.

Dining room floor is very cold in the winter. Can cellulose loose fill be blown in between dining room floor and vapor barrier of the R19 insulation. Have 90 yr old farm house attic floor insulated well! I was looking for something for the roof rafters. I see all new insulation products that will not interfere with the attic floor 20 in on center. Paper-faced batts and rolls feature narrow paper strips on each side that fold out.

Unfaced batts and rolls are also suitable for walls. No special attaching is necessary because the batts are lightweight and sized to fit in standard stud spaces snugly. Just measure, cut and push them in place lightly. Once the batts are in, install a separate vapor barrier, such as plastic sheeting over the entire wall, stapling it to the studs.

For attics with limited access, the best way to insulate is often with blown-in insulation. Made from lightweight cellulose, fiberglass or rock wool fibers, blown-in insulation comes tightly compressed in bags but with an insulation blower, the fibers fluff up and float softly between ceiling joists. Additional dams are necessary around electrical outlets, stove pipes, or can lights, all of which you can form with cut pieces of batt insulation. Rigid foam boards come in 4-byfoot sheets and are very lightweight.

While you can cut and fit the boards between wall studs or rafters, they work best in places like crawl spaces, where special glue secures them to concrete foundation walls. To form a seal, cut and fit rigid foam insulation snugly and then apply sealant tape over the seams. The most common is paper-faced insulation.

The insulation is installed into the wall cavity with the paper facing into the house. This is very important — the paper, which is the vapor barrier, always faces the warm side of the house. Wiring should be installed before any insulation. Electrical systems and insulation both need to be installed inside the wall cavities of your home, and it is important that they go in in the correct order.

Place unfaced insulation on top of existing material, such as loose-fill cellulose. Press the insulation firmly into place between joists, taking care to not compress the fiberglass and reduce its efficiency. Fasten batts loosely to perpendicular joists with plastic straps just to keep it from shifting. Fiberglass Insulation In most climates, it needs a vapor barrier. Some builders rely on batts with attached kraft-paper facing to do that job, but Tom recommends unfaced batts, covered in plastic with all the seams taped shut.

Unfaced insulation is great for new construction, remodels, walls, floors, ceilings, basements, attics and crawlspaces. Picking the right face is essential with fiberglass insulation that has a vapor barrier meaning with Kraft paper or foil attached on one side.

It should always face the warm-in-winter side.
