LESLIE: Doug in Texas, you’ve got The Money Pit. How can we help you today?
DOUG: I’ve got a 30-year-old home here in Northeast Texas. Wanting to know the best way to upgrade my insulation in the attic. It has what I would call – it looked like a recycled newspaper, maybe, blown in there. Probably about 2½, 3 inches thick. And wondering if I could just blow a new type of insulation on top of it. Or do I need to do preparation first?
TOM: Yeah, you can add additional insulation and that makes a lot of sense. But I would not put new insulation on top of that old insulation. Because the old insulation is probably settled down, compressed and it’s not insulating as well as it should. So what I would recommend is that you remove the existing insulation.
Then, if you want to go with blown-in, there’s actually a product out now that allows you to do your own blown-in insulation. It’s from Owens Corning and it’s called AttiCat. And the way AttiCat works is you go to your local Home Depot and you purchase the bags of AttiCat insulation. And if you buy 10 bags, they will give you the blowing machine for free. The rental – there’s no charge for the rental.
And then the blowing machine gets positioned outside your house or in your garage or whatever. The insulation packages slide into it. It’s almost designed as a slot; you put it right in the side. You take the hose up to your attic and it’s remote-controlled, so you can turn the machine on and off and control the flow.
And then, this type of insulation gets into the nooks and crannies, it expands nicely and it’s low dust. So it’s a very easy way to do your own blown-in insulation and get a really good, contiguous, solid application of insulation in that attic.
LESLIE: And a targeted application, as well.
TOM: Yeah. And you could do a whole house in about four hours.
DOUG: OK. Great. Well, I appreciate the advice. I’d like to maybe get a big vacuum cleaner to get the old up.
TOM: Yeah. The new insulation will go in in four hours. Getting the old stuff out, though, that’s going to be a day. Good luck with that project.
DOUG: Alright. Thank you for your help.
