What is the difference between R19 and R30 insulation?
Insulation in your walls and ceilings slows down this heat transfer.
The bigger the R value, the better the insulation is at slowing down the heat transfer.
So R19 is better insulation than R13, and R30 is better than R19.
The larger the R value, the better the insulation value..

Which type of insulation is most effective?
Aerogel is more expensive, but definitely the best type of insulation. Fiberglass is cheap, but requires careful handling. Mineral wool is effective, but not fire resistant. Cellulose is fire resistant, eco-friendly, and effective, but hard to apply.
What is the thinnest insulation with the highest R value?
Aerogel insulationAerogel insulation offers the highest R-value of any insulating material at less weight and thickness—ideal for construction, refineries, pipelines, and thin-gap thermal barriers. Browse our superior selection of superinsulating aerogel blankets below.
What insulation has highest R-value?
Vacuum insulated panels have the highest R-value, approximately R-45 (in U.S. units) per inch; aerogel has the next highest R-value (about R-10 to R-30 per inch), followed by polyurethane (PUR) and phenolic foam insulations with R-7 per inch.
Can I put R19 in 2×4 wall?
Thanks! R19 compressed into a 2×4 stud wall should give you about R14 I believe, so if you can’t return the R19 you already have to the store to buy cheaper R13 batts, you might as well use it up.

Can you over insulate a house?
It is possible to over-insulate your house so much that it can’t breathe. The whole point of home insulation is to tightly seal your home’s interior. But if it becomes too tightly sealed with too many layers of insulation, moisture can get trapped inside those layers. That’s when mold starts to grow.
Which is better insulation R30 or R38?
026 and R30 has a U of 1/30=. 033. So R38 is about 20% better. U can then be used to calculate heat loss.
