Asked by Curious November 10, 2020

Answer

Given the large size of the cavity, you will have to get creative on how you support the batts. Chicken wire might be an option. Other methods can be found in our installation guidelines: According to the installation guide for installation in a vented crawl space: When installing Kraft-faced insulation, use wire lacing, screen or stiff wire fasteners to hold the insulation firmly in place. https://www.jm.com/content/dam/jm/global/en/building-insulation/Files/BI%20Toolbox/Energy%20Star%20Installation%20Instructions%20JM%20Batts_Rolls_FG.pdf

Can this be used on a 2x4 farmed wall.

Asked by Glenn October 22, 2020
1
Answer

The R-value is determined by the thickness of the insulation and the depth of the wall cavity. So if you used this product in a 2x4 wall you would need to compress the insulation to fit and it would decrease performance. You are better off buying the R-15 product which is designed for 2x4 walls.

Asked by BB August 27, 2020

Answer

For 2 by 8 rafters, the depth of cavity is ~7.25 inches. In order to achieve maximum R-value you would ideally need to find a product that will fill the entire stud cavity. Johns Manville R-22 which is 7.5 inch thick would be the right thickness. However, i am not seeing the R-22 product in the 24" width that has a kraft facing on it. Thank you.

Does this have the fold down tabs to stapes both sides to the truss for overhead install?

Asked by DWT March 17, 2020

Answers

Yes, it has put down tabs to be stapled to the studs . I instead put it in the floor of the attic over my lanai and it lowered the ceiling temperature from 98 degrees to 88 degrees and made the lanai more comfortable.

The north-facing lanai of my house in Florida was always hot in the afternoon. My infra-red gun showed the lanai ceiling was 98 degrees. I checked in the attic and there was no insulation over the lanai. I built a walkway from the hatch on that side of the house back to the attic over the lanai and added some lights. The rolls of insulation would not fit through the hatch, so I cut each roll into five 8' lengths, rolled those pieces into smaller rolls and put two of them into a large garage bag. That made it easier for me to hand up the insulation through the hatch without brushing the insulation me. I added radiant barrier foil to that section of the attic and put down two layers of insulation, one between the trusses and one over top of the first but perpendicular to the first layer. That lowered the lanai's ceiling temperature from 98 degrees to about 88 degrees and made the lanai more comfortable. My only complaint, and why I gave it a 4 rating, was because the rolls did not fluff out to the full 6" thickness. I'll monitor the insulation and if it fully fluffs out, I'll update this review and change the rating to a 5.

Seeds Program Review
(What's this)
This insulation is cut and made especially for stud walls but can be used for any application with 16" on center spacing between the studs. , It has an R-19 resistance insulation value and is faced on one side with kraft paper. If you need to cut it you can easily do so with a razor cutter or box knife . it is very easy to staple into place and easy to handle as it is very light as well .

Seeds Program Review
(What's this)
Bought this to insulate the Shed/Outbuilding roof. Nine (9) Pieces came in the bag compressed. Easy to unpack & get ready for the install. Wore Goggles over my glasses an a long sleeve shirt along with 2 pairs of Grease Monkeys Nitrite Gloves. Friction press into cavities which held the insulation batt in place & gave me the ease of adjustment while stapling into place. The fold down tabs that are placed along each side made for a very quick install. I came away with the feeling of WOW! Buy without hesitation.
