Product Overview

Choosing The Right Insulation

Faced Insulation


Face insulation uses kraft paper vapor barrier to control moisture transmission between 
walls and floors 

*Check your local building code for requirements
Unfaced Insulation


Unfaced insulation does not have a vapor barrier; used over existing insulation in the attic, or where moisture control is not needed

Rolls Insulation


Continuous rolls are easy to transport and can be cut to length; great for large areas

Batts Insulation


Come in pre-cut lengths for faster installation and each package contains more square feet than rolls; ideal for framed cavities

Blow-In Insulation

Blow-In Insulation

Installed using blowing machines, best for adding additional insulation in attic

Regional R-Values

Customer Questions & Answers

Installing insulation on existing insulation.

I bought an old house that currently has R-11 fiberglass insulation between the 2x8 rafters. I want to install R30 roll out fiberglass over the existing insulation. Can I lay the new insulation over the old insulation? Does there need to be a layer of insulation that covers the rafters?
Asked by: Anonymous
It sounds like the existing insulation (R-11) is coming up short of the of the top edge of your 2x8 rafters / ceiling joists. I would run R-13 Un-faced on top of the R-11 between your ceiling joists to fill the Void, and then run the R-30 un-faced perpendicular to the rafters / ceiling Joists. That should give you a little more than R-50.

my Attic is done with 2X8s and this is thicker, I want to put plywood down for storage as this area is over my garage. Will this be a problem

Asked by: Anonymous

WHat gives...?

I added this stuff to my cart it was 13 and change a roll...When I went to check out it jumped to the current price of 17 and change a roll? That's ludicrous
Asked by: headhunter
This happened to me before and it had to do with the store selection. I found this insulation is cheaper in other parts of the country and when I selected the correct store, it jumped up a few bucks.

does my roof/attic need faced insulation: it has none right now.

just moved into a home that the roof is only partially insulated. do I need to use faced insulation:
Asked by: sharky
You need a vapor barrier next to the living space. Kraft faced will work if placed the paper side down.

R-30 Unfaced Insulation Continuous Roll 15 in. x 25 ft. is rated 4.5 out of 5 by 101.
Rated 5 out of 5 by from Lessons learned on installation Installed ten rolls in three hours. Easy to do. Just need long sleeves, knee pads, glasses, knife, two boards to cut it, and six foot pole to put insulation in position. Two tips. 1) I must have bumped my head a 100 times on the rafters. Wear a bicycle helmet to protect your noggin. 2) Use a strap to hold your glasses on. Gets a tad sweaty and they start to fall off while your hands a full. Tried it without glasses, but the dust started getting in my eyes. Regular safety glasses worked just fine. If you find some that are wrap around goggle type, they would do a tad better. I will compare electric bills before and after and post the results later this summer.

Rated 5 out of 5 by from Hard job made easier with this product My husband and I purchased this insulation on sale and chose this brand due to its eco friendly properties and R-30 rating. We installed 50 rolls in our attic over a couple of weekends. This product performs as advertised and reviewed: No vocs, itch free, can tear it with your hands if you left your matt knife 20 feet behind you on a board in the attic. Absolutely the best choice we could have made for our project. If you have a low ceiling attic this is the way to go.....easier to roll and push with broom handles to edges than hunch and crouch with the blow-in type insulation which is what I helped my brother do in his attic.

Rated 5 out of 5 by from Great product Before I put this insulation my house was either too cold or too hot (two levels house). It works wonderful. This morning the temp outside was 59f and the house was 72f inside, the tstat setting was 68f. The heat never came on all night, unbelievable! I first sealed all the holes inthe attic, with painters caulk, to stop all air leaks, specially around the light. I did not removed the old faced insulation, I was too lazy to removed it. I then layed down the unfaced insulation over the old one and then another layer accross to cover the joyces,and now I have a more efficient house.

Put it in attic space of small rooms added to house. went up easily with the support rods. I used them because I would have no access to the space once sheetrock is hung. Weather has been really mild so no real difference in room temp. I'm sure once the summer weather hits and room is in use. I will be glad I did. Space was originally added for storage and very uncomfortable to be in last summer.

I found this product extremely easy to work with, recommended gloves/long sleeves and a mask. I used in my kitchen for insulating and soundproofing. I used both faced and unfazed behind the green board. It worked well in between the plumbing and overall.. Im very pleased. I plan to buy more for another layer or two in my attic.

Rated 5 out of 5 by from Good product at reasonable cost I've placed about 12 of these rolls in our attic so far this month as an additional layer over some blown-in insulation. The insulation is easy to work with. I use eye protection, mask, gloves, and long sleeves and pants, and have not had any problems. The rolls are about 23 inches in diameter which make it relatively easy to move up through small attic openings. The insulation expands rapidly and is easy to cut when necessary. There are some good videos available online on how to use it. See Owens Corning's videos on YouTube. You really can't go wrong with this for attics.

Rated 2 out of 5 by from not happy anymore. bought these to add to existing ones in the attic and they are not good at all. when you unravel them it separates,it is aggravating to use. you end up destroying it trying to piece them up.
Date published: 2017-03-25
Rated 4 out of 5 by from Worked well but Some of the rolls seemed to have either been defective or exposed to some water. We were able to use it regardless but it did make it slightly more difficult to install.
