Re: So I want to get my attic insulated...
Many younger people don't know what an attic fan is. Our daughter in Ft. Worth has one in her house, but it is maybe 60 years old.
I was thinking of either an exhaust fan through an outside wall, or a big circulating fan blowing the hot air out through an open garage door. With any type of eshaust system, you must have an intake to let outside air in. That should not be through an airconditioned space.
The point is, when it really gets hot, we'll sit around and complain, but we probably won't do much of anything else. |

You want to be careful with attic fans, if it has too high of a CFM rating it can pull your cool air into the attic making your AC work harder. |

You just need a way to remove the heat from the space. An exhaust fan to the outside will work.

said by Redshirt 24  :said by Bilbo8 :Most places don't recommend insulation over the garage or any space that is not heated or cooled. The insulation keeps heat from moving from the hot space to the cooler (less hot) space. Generally, you want the heat to move out of your garage in the summer, especially after you have just parked your car after a hot drive. Of course, this works better with plenty of ventilation in the attic. Never heard that, myself...not that I'd be complaining that much if it's correct, though, since that chops a nice chunk off the relevant square footage I'd need to get done... Yeah, that might be true for a small garage, but I have an oversized 3 car, only a car and motorcycle are parked in there, the rest is workshop.

Does anyone have any personal reviews of spray on radiant barrier paint? I have a feeling that it's a scam with negligble benefits. I'd rather do the foil based barrier applied to the rafters, but then I'd have to look at putting in ridge vents... so it's even more work involved.
Or am I better off blowing in another 6-8 inches of insulation? I have R38, but it's settled in some places. |

I just had insulation blown in over my garage by Stark Air.
The area was about 650 SqFt with and they charge me $550 to cover that 8" deep.
The stuff they used is, of course fire retardant, but also does not make you itch like fiberglass does.
They were quick, professional, did a very good job, and did it exactly like I had asked them too.
They are in Euless, but I'm sure they go up your way.
