Insulation Blower?

I am thinking about buying an insulation blower for fiberglass insulation.

I am primarily a roofing contractor and we do insulation as an add-on. We have done about 12 insulation jobs along with the roof replacement.

We did some roofing on an apartment complex and now the need insulation.

Do you know if all insulation blowers make the fiberglass insulation expand at the same rate?

We’ve been using the Owens Corning AttiCat and it seems to make the insulation expand more than what they say it will. Every job that we did had bags left over. I am not sure how to estimate the quantity of bags needed.

I am thinking about buying a better machine but I am not sure if other machines will make the fiberglass expand as much as the AttiCat.

The machine I am looking at is the Cool Machine 1500. I can get it for around $5200. They say it will blow around 755 lbs per hour of fiberglass.

Do you think this would be a good machine for me?

Re: Insulation Blower?

I think you would be better off looking at cellulose.

My son's machine is an Insulmaxx 4000. Made in Oklahoma City.

There are usually several on eBay at any given time.

Cellulose is better. The amount that the material is fluffed has to do more with the amount of air and gate settings. The machine you are looking at seems fine but I like krendl as a brand for smaller blowers

Re: Insulation Blower?

Here is a link to blower info.

Here is a link to comparison chart.

THe guy selling these machines says they are made by Dave Krendle whatever that means.

I have attached a quote in Excel.

He says I would have to pay for it in advance and have it shipped to my house. How can I know it's legit?

Re: Insulation Blower?

It's not the machine that expands the fiberglass to a greater or lesser amount. It's the bails you buy. For instance. If you buy the bails from HD they: weigh 26 lbs.
If you buy from a distributor they weigh 33 lbs, cover more, expand more and settle less.

The Moral of this story is... Well,.... I think you get it

Hey Mel! I'm an insulation contractor and the Cool Machine would be a great blower for you, its a big step up from the Force 2 blower which most lumber yards carry and for you just adding to your roofing business you don't need anything bigger than the CM 1500. I will give you a number to call on the CM 1500 Rob is such a nice guy to deal with, he will take care of you. 616-510-3100
