R-value

So they're usually only managing heat flow in one direction.

Now lastly, R-Value, it doesn't measure any acoustic properties of the insulation.

So if you are looking for sound insulation or for your thermal insulation to do both jobs, then you'll need to check with the specific product itself to see its own properties.

Now, let's have a look at ceiling and roof insulation.

But spray foam does three things.

really well it air seals it also provides a higher r value so think of insulation it provides a higher r value per inch among any other insulation type and in some varieties it can also act as a vapor barrier So think about this, if your home needed air sealing, really high R value and like vapor impermeability, you just knocked out all three of those by going with closed cell spray foam insulation.

That is why builders really like it.

And it's much faster to do all three of those in one go.

Now, you may tell me, I'm fine with spray foam.

I love it.

I'm in the camp where I think, you know, the performance hits it out of the park, the R value.

I think it's a great material.

So what's the name of your podcast?

Oh, the "R-Value" podcast.

I should remember that sometime when I say the podcast.
