Has anyone blown insulation?

Not particularly expensive to DIY. Buy a minimum number of bags and Home Depot lets you borrow the machine. It's easier with two people...one to dump bags in the machine, one to handle the hose.
 
Several areas on my metal pipes that carry my heat and air do not have insulation around them! I was up there messing around and knocked one pipe loose completely, so now I have to go get some duct tape and try to fix it

3 sheet metal screws or more per joint and foil tape. Code call for 3' worth of R-4 to R-11 insulation pending climate zone for duct work that go from hot into cold space to prevent condensation. But, not thing stopping you from insulate all duct works except for fireplace/stove vents.

PS. Don't get the silver bubble wrap insulation because it is only R-4, unless you don't like working with fiberglass.

I had someone add about 2 tons last year into my attic. It wasn't cheap but they weatherized the rest of the house too. It has been a good buy imo, bills have gone down and its actually comfortable in my upstairs now in this ridiculous heat.

I've looked in my attic, and our definitely is. I was looking into getting batts -- haven't actually compared the price to have loose stuff blown in, but I figure that the batts will be neater, and I could do it myself. But I did the math for the square footage, and it isn't going to be cheap for a significant R increase.
 
Yes in a past life I worked with blown in insulation. I don't know where this thread crazy dead end is going, but the chief value of blown in insulation is filling side wall with no previous existing side walls insulation with an method of installing that does not require removing existing side walls to add insulation in existing construction.

When one is dealing with attics that are more accessible, its far better to use off the shelf Fiber glass by the bag in the form of batts methods.
 
There was a stipper one night named Insulation at this bar I was at....called "The man hole".....but....I cant say anything more.
 
It's cheap and easy to do. BUT, you need to do a little research so you don't screw things up. It's not quite as easy as just aiming a hose into your attic and letting the stuff blow out; but close. There's some prep work to do ahead of time, to make sure that their air vents in the soffit aren't blocked.
