insulation is the best way & wonderful thing because it saves energy. Insulation in your home makes your home/ office buildings more comfortable. It is less inexpensive & long lasting. Everything is depend on only well-installed spray foam insulation is always best. There are lots of insulation methods available in market. Yeah, different materials have their different properties, with their advantages and disadvantages. But if it is installed well and protected by water vapor, it will do its job for a long, long time.
So, there are my 2 Ways to Get the Best Insulation in Your Home or Office?
I’ll show you the calculation what best for your house & office and it comes out a lot less than R-30. In fact, at R-17 it’s about half. That means you have almost twice as much heat flow even though you have the same amount of insulation.
So, the rule number 1 is to make sure your insulation contractor either we or anyone is selling you on how much thickness. That means they are filling suitable R-value thickness. Here only one thing matters the applied insulation thickness should not be less or high.
In a 4×2 wall where you need R-13 thickness to meet code, spray foam contractors usually install 2-3 inches of closed-cell spray foam. Since it’s usually rated at about R-6.5 per inch, that means if, say, 25% of your wall has only 1.5″, you get about R-10 there instead of R-13. If the rest of the wall is right at 2″ thick, your average R-value in the cavities is 12, not 13. You’re not getting what you paid for.
Even if you’re not building a new home, you can still take advantage of this property of insulation. If the insulation in your attic is lumpy, you can save energy and probably enhance the comfort of your home by spreading it out uniformly.
When we inspect a house, we have to determine the R-value for each insulated assembly and also the grade, I, II, or III. Grade I is the best, Grade III the worst. You get the thickness to achieve the R-value you’re paying for, you should also make sure the insulation is installed in other ways that ensure it achieves maximum R-value.
The protocol is based on looking for two things. First, the amount of missing insulation determines what grade it might be. Here’s the diagram, with the dark areas representing gaps in insulation.
Officially, Grade I means essentially no gaps, Grade II can have up to 2% gaps, and Grade III can have no more than 5% missing insulation.
