Questions & Answers

how many square feet will this cover?

Asked by: goodyz
LookingForInsulation is incorrect. He forgot the multiply by 12 one more time. It's around 360 sf as btayso said.

How wide is it

Asked by: Lon
I have a piece of it right here. It varies from 15" to 15 1/4". The stud or joist bay is 14 1/2". It is made wider to provide a friction fit and so there are no gaps at the edges. When you install it, DON'T push the edges in and leave them that way since you are reducing the insulating value. You want it to be flat across, not pushed in at the edges and bulging out in the middle. Compress the edges toward the middle as you install it. If you need to cut it across or the long way, always made it about 1/2" larger or a bit more. I have installed several hundred sf and I love it. MUCH better than the O-W thermafiber batts. That stuff is crumbly and messier than RockWool.

Is this isolation rodent resistant?

Asked by: Fatdaddy
ROCKWOOL is non combustible material made from BASALT rock. The fire resistance details are on the product data sheet at the following link https://cdn01.rockwool.com/siteassets/o2-rockwool/documentation/technical-data-sheets/residential/COMFORTBATT-Exterior-Wood-and-Steel-Stud-Thermal-Batt-Insulation-Techdata-US.pdf?f=20190118110729

Hi..Does anyone know what the relaxed thickness of these batts is? I know it says the thickness is 7.25" but can it be compressed in a 2x6 wall without causing problems during drywall installation. Thank You in advance.
Asked by: scenic2
The thickness of the R30 product is 7.25". We do not recommend compressing the face of the material as this will affect the R value. You will lose an approx R4 per inch of compression. Please note in a 2x6 you have 5.5" of cavity depth. The 5.5" batt R23 is sized at 5.5" for 2 x 6 studs. Another factor to consider is this is a very dense material which will want to spring back out when compressed. This may put undue pressure on the drywall and pop the screws.

When installing the insulation I wore gloves and I thought everything would be okay. But the dust got in between the end of my shirt and the top of the gloves and caused redness and irritation that I was still experiencing the following day. I paid top dollar for this insulation and that's what I have to deal with? Not recommended.

We built 2 rooms and kitchen to a mobile home and they were insolated but not under floor, so the climate was hot on Summer and cold in Winter.
