Insulating Garage Attic

6 posts in this topic

I just finished all the sheetrock on my ceiling. Now I want to put R49 in my attic. I was thinking of cellulose. How hard is it? I put in all the soffit baffles before sheetrocking. I can do the whole thing for under $300 or pay to have it done for more.

It really easy to do your self Just have someone load the hopper for you without plugging it up. Take a tape measure with you and start in the back corner and work your wat to the access hole. Buld up around your access hole the height of the insulation first. Do it when its not super hot out. It can get to be a cooker up there. I wouldn't hire it out unless your not confident to do your self. Good luck.

Blowing it yourself is so easy a one handed blind monkey could do it.

Usually the big box stores give you the blower rental for free if you buy so many bags of insulation. I believe its 20 bags or so. Even if you don't need that many just buy the minimum number to get the free rental and return the unused stuff later on after you've gotten the free rental.

Like said above just start in the far back corner and work your way to the access hole.

There are a few tricks that can make it easier.

Like marking the needed height of the isulation in several points in the attic before you start blowing. Then you can just blow the insulation until in reaches your marks. Its saves you from having the keep track of the tape measure. If you drop the tape measure while blowing it can be hard to find in that pile of fluff.

Also do it on a cool day. When I did my attic I thought I was going to pass out it was so hot (mid 80's outside, about a million degrees inside). I told my friend if he doesn't hear from me in 10 minutes come up and find me.

Other then that the hardest part is loading and unloading the blower from your truck. Its a heavy little bugger.

Wear masks too. It gets real "dusty" with all that stuff, even the guy atr the hopper. I am not usually a real "safety at all costs" guy, but when we did my brothers I was glad we both had masks.

I like the advice about marking the trusses ahead of time with sharpie, then don't need tape later.

Really easy...

i've blown a ton of insulations ranging from adding to my house attic, to 80x300 hog barns. Do like said above, figure out your height and mark it on the webs of the rafters with a black sharpie. dont waste money on the insulation rulers. it takes more time installing them than marking with a sharpie. R-49 seems like alot for a garage!

wear a dust mask, and i always put on a long sleeve t-shirt otherwise when you sweat it sticks to your arms. Goggles are good too, i have contacts and the dust gets in your eyes and messes up your vision.

    • The GOP feels a need for some reason to pick up the mess in healthcare that the Democrats created yet in the process, they seem bound and determine to own the mess themselves. despite the public crowing, the DNC would love for the GOP to get stuck in this tar pit, also   Let ObamaCare collapse on it's own. Do nothing
    •     Actually, I think it sounded like breakfast to D2E....  
    • Big day today. Obamacare is about to be replaced with Obamacare light.Maybe. But if the Koch bros get their way the bill won't pass.
    • Child please. You know I am right and it's OK to admit you thought Aleppo was something Lorne Greene fed to his dogs.   
    •   How does the song go "I see your true colors shining thru".
    •   Yawn...   8 months...9 months.... or more, investigating the evil Donald and still nothing ??   Maybe just join the Duffman and have a good cry ....    
    •   You're getting sort of deep there Jigsaw, but yeah, who really gives a rip if someone calls Rachel Maddow a dyke on an internet forum?       politically correct  ► adj. Of, relating to, or supporting broad social, political, and educational change, especially to redress historical injustices in matters such as race, class, gender, and sexual orientation. adj. Being or perceived as being over-concerned with such change, often to the exclusion of other matters.     There's a good article about it here: https://www.academia.org/the-origins-of-political-correctness/
    •   Lol...   Another progressive snowflake melting down in the warm Trumptember sun.   Epic....  
    •     Ok,drama queen.   There is no mama or Polish jokes, having a go at wives and children.    Stop yelling rape because someone accidentally brushed into your b.o.o.b at Costco. When on the defense down here, being egregious is the last resort for most when cornered. Only second to calling out for martial law that once exisited in these parts. You want to live by the sword, well, you know how it ends.   As for personal relationships, unless you boys are neighbors and all groomsmen then I wager this is nothing more then a geriatric Tinder site, doubling as a support group. Online relationships can be anything they want it to be, except reality.    You either are going to get the what and why of what I said or or you're not. It was no mistake and very intentional. As I said, not a rip but an easy observation.   Im not down here to make pals and build lasting relationships as the very idea of that in this setting is a contradiction in its self. (misery loves company cliche applies) Im just giving in to a guilty pleasure which has almost run its course.   In closing, it's game here. Not a discussion or a debate. A perpetual cat fight. Ideas and opinions are made without ever directly stating them and they carry the same weight as if they were to be.  Just be aware enough to catch it.   If you do not like my brand of Vodka. That is ok with me, it's not for everyone. I respect the voicing of it, I encourage.   But just know, down here, all of you are get away drivers but hold the same culpability as the one inside robbing the bank.
