R38 Insulation Thickness: Explore Its Uses And Roles

Meta Description:

If you want to know a detailed note on R38 Insulation Thickness, you can read this article. Here we will provide you with everything that you should know.



What is R38 insulation thickness? Where to get it installed? Is it easy to go ahead with it, and how beneficial is it? So many queries are pounding in your mind? Stay along; you are at the right place – here, you will find a detailed answer on this insulation type. 


Insulation is an essential step for home renovation or home safety – every kind of thickness and R-value cannot work for you, but the right one meets your home’s type or location, etc.


R38 is a kind of insulation that reduces around 97% conductivity level and cuts your energy cost. There are more benefits of this thickness and certain ifs and buts that you are supposed to consider while getting the R38 installed.

R38 Insulation Thickness: All You Need To Know About 

Insulation has various R values, and people use them per the specific climate zone. The thickness or depth of insulation with an R-38 value depends on the thermal conductivity. Normally batt and roll insulation is used for the attic and other areas of the house. They are almost the same, but the main distinction is the thickness. Insulation is made of fiberglass, rock wool, cellulose, or spray foam. Insulation with an R-38 value helps to lessen the thermal conductivity to almost 97 percent compared to no insulation. So if you need to save energy bills, go for insulation in the home using R38 and stay happy. 

R-Value: What Actually Is It? 

The R-value is very important when deciding about insulation for your attic. It shows the insulation’s thermal resistance in kelvin per watt. Hence, it shows the material’s resistance to thermal conduction via the material thickness. A material with higher R values will be more thermally resistant than one having lower R values. Therefore, we can say that the R-value is not directly proportional to the thermal conductivity.

Insulations with fewer R values will be less likely to insulate houses than those with an elevated value. The one-liner of this discussion is that always choose the insulation with an accurate R-value based on the climate zone as it will ultimately help to enhance the energy efficiency of houses. Accurate insulation will ensure there is less heat loss just because of appropriate thermal conductivity. 


If you insulate the home properly, it will have more thermal conduction, and as a result, it takes less energy for heating and ultimately saves costs on paying bills. While computing the R-value, we only consider the thermal conductivity and forget about the radiation and thermal movement via convection. Hence, try to use other methods such as kraft paper with insulation. The foil paper will help you face a warm environment and decrease radiation and convection. The addition of kraft paper has no effect on the R-value. Instead, it will lessen the radiation and thermal convection. 

Inspection of Insulation Attic is Must 

Go to your home insulation attic and investigate its current condition. It is better to calculate the insulation’s current level. The attic must have a specific amount of insulation. The insulation used for the attic depends on the area you reside. If insulation has any issue and you need to change, do it immediately in your free time or take help from a professional. 


R38 Insulation: Where You Can Use This?

Attic insulation having an R38 value can be used in 1 to 4 climate zones. It is recommended to be used for ceilings in 4 to 5 climate zones. In the case of floors, R38 insulation can be used in 7 and 8 climate zones as it is great for energy saving and comfort. R38 insulation can reduce thermal conductivity to nearly 97 percent, meaning heat loss will be 97 percent less. Hence, it is proof that less energy loss will help keep the home warmer. It ultimately reduces the electricity bill too, so it is considered a big relief!

What About Batt insulation Made of Fiberglass

You must use fiberglass batts for insulation of at least 10.45 thick to get the R38 value. During manufacturing, the makers will keep it thicker so that after little compression, it will not lose the thickness and remain at the assigned R-value because contractions will always reduce the R-value of batt insulation. Fiberglass batt insulation is made of fluffy pink bats available at the stores, and people love it. The specialty of fiberglass insulation is that it is made of about 80% recycled material and is soundproof. Hence, this batt’s insulation is present in the market with different R values and used in various home areas. They are specialized to use in almost all climate zones in Canada and USA. Mostly you can get the insulation made of fiberglass in 16 or 24-width batts. During installation, you must put all your attention, and one thing to remember must avoid compressing it too much and try to fit inside the frames carefully and adequately. Too much compression reduces the R-value, and pores will become fewer inside the insulating material. 

Try Insulation Using Rockwool Batts 

You need a Batts with a thickness of at least 11.25 to get the R-value of 38. It is comfortable to handle and also pre-fabricated. It is best suited to attics and crawl spaces of the floors. Outside walls made of wooden or steel buildings are other areas where you can use them. Rock wool batts give fire resistance and noise reduction, providing a calm and quiet environment for work. They are lightweight, which is why installing and taking them from the store to other buildings is so handy.

The Bottom line

R38 Insulation Thickness is helpful for your home as it increases home security and decreases the conductivity. It is an effective and expensive insulation. If the value of R is higher the insulating quality of the material will be great. You can insulate your crawl space, walls, attactic by using this R38. The advised level for attics is to insulate about 10 to 14 inches of R38 based on instualting type.
