The blown insulation, or what I call blown insulation is what you're thinking it is. I call the stuff in a can foam insulation.
Basically the blown stuff comes in a plastic bag packed very tightly and it looks like a bale of hey. The blower is a machine that has a paddle wheel in it and a waste gate on the side to control the speed at which the insulation is blown out. There is a length of 2.5 inch hose and that is how you spray the stuff around. In a wall you would want to start at the top and let each cavity fill. There isn't enough force to start at the bottom and hope to fill upward. Of course that means you have to cut holes in the wall large enough to fit the hose in. I used a hole saw so I could put the piece back in the wall later. One warning. It takes at least 2 people to do this. The person with the hose, and someone to open the bags, break up the bales and keep the machine full. It helps if you are in the attic to have a message relayer somewhere between you and the person filling the machine. You will need to where a respirator, both people, and it can be a game trying to relay a message back to stop the machine or whatever. ----- Original Message ----- From: Scott Howell To: blindhandyman@yahoogroups.com Sent: Sunday, September 13, 2009 6:21 AM Subject: Re: [BlindHandyMan] spray insilation question. This may be a stupid question, but not knowing how this spray stuff works, I'm going to ask. First I thought this was just insulation that when blown in was still a fluffy material if you will, not that stuff that comes in a can that expands and makes one hell of a mess you clean up with a knife. And yeah, I used that to seal around a dryer vent and didn't realize how much it expanded until my wife saw it the next day. WOrked great, but man I had fun cleaning that mess up. Second, if it is the fluffy stuff like regular insulation, couldn't you if it were possible of course either blow it from the top down assuming you could find the area between the walls or into the areas like plug boxes etc. assuming you could move them? I don't know how large the holes have to be, but like I said, don't know much about this stuff, but I'm getting interested. tnx, On Sep 12, 2009, at 9:39 PM, aadorno wrote: > no I don't have it under my roof right now but I am really thinking > about getting it for my walls ceeling and floors. > ----- Original Message ----- > From: Shane Hecker > To: blindhandyman@yahoogroups.com > Sent: Saturday, September 12, 2009 3:59 PM > Subject: Re: [BlindHandyMan] spray insilation question. > > I'm assuming you are talking about the foam insulation.
