How many bags and at what thickness to upgrade from R20 to R60 ~ 900 sq ft.? Thank you

Asked by: BluenoseBuoy
12.5 bags will add R24 so double that will be 25 bags would be R 48 added to what you have now so a total of R 68 or you could do  ...18.5 bags would give you a total of R56.

can this insulation be installed without using a blower?

Asked by: weddew
Rather doubtful, as it is packaged highly compressed and, operated properly, the blower ensures even expansion and application of the insulation.

Do you have to use a machine or can you shake and rake into place.?

Asked by: Bikertwin
You have to utilize the blower in order to get it fluffed up racking just will leave in balls and not have uniform coverage

What is the maximum slope that this can be used in a cathedral ceiling?

Asked by: Lakeman Too
While a slope specification for this product is not indicated anywhere I’ve looked, the ‘Pro’ version of the “Pink” insulation is stable on sloped ceilings up to 4.5/12. As the products and very similar, this product probably has similar capability.

Can this be used on a sloped ceiling? If so, up to what slope?

Asked by: LakeMann
Other blown in products can be used up to a 4.5/12 slope. Hopefully a JM rep can chime in with their spec for this product.

"Attic Pro" Blow-In Attic Insulation - Fibreglass is rated 5.0 out of 5 by 7.
Rated 5 out of 5 by from Great product, easy to install This product was exactly as described; calculated amount was spot on. We installed the insulation ourselves with the blow in machine provided free of charge. We watched a number of Youtube videos on how to blow in the insulation, and "their" way didn't work; "their" way allowed the insulation to expand too tightly in the machine and not drop down into the paddles. I found it best to set up a table on saw horses, cut a bale into 3rds and then feed 1/3 into the machine. It took us 3 hours to do a 1300sf attic.

Rated 5 out of 5 by from Excellent quality and best price I got this on sale 15% plus save the tax event and as i purchased 12 bags Lowes gave me Johns Manville Blown-in Insulation application machine rental free of cost. total i saved like $250 to $300 compared to other places.The machine is cool piece and hassle free to use. Thanks Lowe for bringing better products and best deals.

Rated 5 out of 5 by from Easy to install, great price. Had woodchips for attic insulation, heating costs have been brutal in winter. My local store sold me this for $39.99 a bag (compared to the $52.67 currently online) with free delivery and free use of the blow in machine. My wife and I installed 30 bags together for an R-60 value in 3-4 hours after watching a few quick YouTube video's. We found cutting the bags into thirds worked better in the hopper than halves. Not as much dust or mess as I had expected and saved about $800 doing it ourselves. I can't yet speak to heating cost reductions but expect a 1-2 year payout.

Rated 5 out of 5 by from Great Product Insulation was easy to work with and install. Bags are much more compact than cellulose fiber. Installation was easy, except that I could not adjust any settings on the machine; for tight spaces you want to turn down the pressure, so the insulation does not compact.

Rated 5 out of 5 by from excellent Bought on sell for 25% off install week later, middle of the Winter .Home felt way wormer and furnace turn on a lot less often.Very easy install takes 2 hours.

Rated 5 out of 5 by from Blow-in Insulation Nice product or work with and the blower worked well as long as you didn’t overload it. I would recommend this product.

Rated 5 out of 5 by from Easy to install Easy to use if you break up the bundles into thirds. Coverage was as stated on JM website.
