R-Value of Insulation (VANITY-Kick Me!)

Speak English!!!

Great, now Obama will send us all to re-education camps because I want to insulate my garage.

[Dr. Sivana]

That is English, it uses feet and watts and BTUs instead of meters and joules. (The kelvin is problably there to get around negative values messing up the math.)

[Eye of Unk]

I live just north of Anchorage, Alaska, my wails are minimum R-19 or R-23 (whichever is on sale) PLUS I have a layer or blueboard on the exterior a minimum of one inch and on the north side of the house is two inches thick, and I have even applied another 1” layer of foam board to the inside of the walls, altogether my wall are about 10” thick, I have seen a reduction of my heating bills big time.

But thats just me, go further north and some people have walls two feet thick, especially places that get down around -70F.

Tonight we’re having Johnsonville Italian Sausages, Cole Slaw and ‘dressed up’ canned baked beans. I add brown sugar, a squirt of yellow mustard, a handful of chopped sweet onion, some crumbled bacon because I have leftovers from breakfast, and a dash of Worchestershire sauce; my recipe isn’t copyrighted...yet..so help yourself! ;)

There is not one single number. You have to basically compute surface area of your house, then you compute the effective R value for all surfaces, etc. So you would do the calculations twice, once with R9 and once with R13, then look at the difference.

However, I would point out that even R13 is not that great; and, you should also evaluate the area for any leaks, which can kill your efforts at saving money on heating bills. Most houses are built for R19 or higher walls, and that is in a temperate zone area like NJ or PA.

Long story short, get the best you can afford, it will eventually pay off, since neither oil, electric, or natural gas is getting any cheaper.

Don't install garage doors yourself.

do not ask me how I know this

[irishtenor]

Except Raineer Beer! Or, what we called Vitamin R in the old days.

[Squantos]

As a friend of mine and Eakers your already insulated from insults........

Spend the extra cash.

[irishtenor]

Nah, way too many hills around here. When we get an inch of snow, people panic and the bumpers get smashed.

[raybbr]

Pronounced, “Braaahts,” smarty-pants, LOL!

Yeah, I know. I'm a FIB (or I used to be). I worked with quite a few displaced Wisconsites. I even know the proper context of the word "bubbler".

If that link doesn’t make you drool...you’re either dead or a brain-addled, card-carrying member of PETA, LOL! :)

They actually sell those pieces of... Well, pig stuff around here in CT. I don't care for "braaahts" in any case. I am a burger kind of guy.

Big, thick 85% ground beef still mooing in the center with a fat slice of onion and tomato with yellow mustard and American cheese.

Exactly. You will have to learn the formula in Spanish and French.....ve vant your garage to be multilingual.

Yes, I know -- it was a joke.

...go further north and some people have walls two feet thick,
especially places that get down around -70F.

It really is "Tougher In Alaska".
And reminds me that I probably should throw in some more insulation
before the return of those sub-zero temps we get for a week or so
here in Mid-Missouri.

Is your garage heated? Are the walls and ceiling insulated and sheetrocked?

Most are not.But since it is the exterior envelope of the house, it will retard the loss of heat between the heated space of the house and the unheated garage.

That’s all the R-value is. It is a measure of resistance to heat flow from warmer to colder areas of air. The higher the R value, the longer it takes heat to move from warm to cold. The more “R”, the more you slow down the heat transfer.

Get the R-13 door and make sure it has good side and bottom seals. You are going to pay for a new door anyway, and not replacing it for another twenty or thirty years or so( your mileage not guaranteed if teenage drivers are in the house). The dollars you pay now will be worth the more expensive energy dollars you will pay in the future.

[ovrtaxt]

it will retard the loss of heat between the heated space of the house...

Hey now. You have to say 'challenge' the loss of heat, or 'differently-able' the loss of heat.

How insensitive.

[exit82]

LOL!! You mean "R" doesn't stand for "Retard value"?

[editor-surveyor]

The difference is phony. the only difference between them is the aluminum foil face on the r13. Since neither of them covers the entire surface of the panels, the insulation is wasted.

By definition, a newbie is anyone that was not here for the Monica frenzie in 1998 ;o)

If you’d whip them into line when they are young they wouldn’t be brats!
