The best way to find out the type and amount of insulation insidean exterior wall?
 

What is the best way to find out the type and amount of insulation
installed inside an exterior wall? By "best" I mean minimum effort and
the least likelihood of the attempt turning into a big repair job.

The wall in question has drywall on the inside and vinyl sidings on the
outside.

Thanks in advance.

Hi,
Where do you live? This is first thing to consider. The location.

Actually, it doesn't matter where he lives. He is trying to minimize
the heat flow out of his house without major rebuilding.

I'm looking for a good answer to the same problem. Sometimes I install
a slider or something that requires ripping apart a wall from the
outside. I just put in insulation at that point. In 1970 they used 3"
bats so it's not hard to justify ripping that out and using current pink
stuff bats.

I thought sprayed-in foam as seen on This Old House might be an option.
I eventually wound up talking to the company (in Canada) that makes
the isocyanate foam. They very clearly recommended against their
product! The problem is it expands and will push off the interior wall
board. This is the $0 solution.

I talked to a contractor about installing blown in cellulose (i.e.,
newspaper shreds). He wanted to add several inches over the ceiling
insulation which already has 6" of pink stuff bats and added fluff.
And, blowing cellulose into the walls involves drilling ugly holes that
have to be hidden. This was the $1700 solution.

I used an infrared remote-reading thermometer to figure out that my old
slider was a major heat lost. 8' slider, Al frame, single pane.
Typical readings: 25 deg outside, 75 inside, window was 45 on the inside
even with the plastic film "storm windows" on the inside and the
outside. I had the slider replaced with an Anderson. $2200 solution.

As it gets colder I can also sense that the new slider is keeping the
place warmer. And, added bonus, it is quieter.

Pull the cover off a wall receptacle or switch and get a
flashlight...might be able to see the insulation where the switchbox or
receptacle box is not tight against the wall covering...you can poke
around in there with a coathanger and feel if there is any insulation
or if you mark the outline of the cover before removal you might be
able to shave off some of the drywall or the wood or whatever wall
covering you have to be able to see into the cavity next to the
electrical box.

I'm not sure how that would make a difference. If the weather is what
you have in mind, the overnight low now is around 40F, and it usually
doesn't snow until around Thanksgiving. Although it's not freezing
(yet), I'd consider any method that leaves an unpatched hole in the wall
overnight unworkable.

buy a blank electrical plate and drill small hole not in a stud.......

look around tape over hole and install blank cover, making certain its
at the same height as regular boxes

Pull a lightswitch box and look.
