Richfield Spray Foam Insulation | How Much Attic Insulation Should I Have?

Introduction

The easiest way to figure out how much attic insulation you need is to look at the depth of your existing insulation and compare it to the national insulation standard. If you have existing attic insulation, measure the depth in inches and multiply by your attic area. Use a ruler or yardstick to measure the R-value of your existing insulation. You can convert this value into inches by dividing by 3. Add these two values together and compare the total to what is recommended for your region. When finished, you should have between 11-22 inches of insulation in your attic based on where you live in Minnesota and whether you are upgrading or doing a whole home job.

The best way to determine how much attic insulation you need (in most cases) is to look at the depth of your existing insulation and compare it to the national insulation standard. The national standard is based on the climate you live in, so it varies by region. In most climates, however, this recommendation will be pretty close:

• R-38: 11 inches of insulation from joists or rafters

• R-49: 20 inches of insulation from joists or rafters

If you have existing attic insulation, measure the depth in inches and multiply by your attic area. Richfield Spray Foam Insulation

If you have existing attic insulation, measure the depth in inches and multiply by your attic area. To get a rough estimate of how much new insulation you’ll need, grab a ruler or yardstick and check out the R-value of your current insulation.

If you already have some type of attic insulation, measure its depth in inches (you can use a yardstick or tape measure) then multiply that number by your total square footage of attic space. This will give you an idea of how much additional material is needed to reach recommended levels.

Use a ruler or yardstick to measure the R-value of your existing insulation.

If you have an existing attic, use a ruler or yardstick to measure the R-value of your insulation. The R-value is a number that represents how well a material resists heat flow, so it’s important for keeping your home warm in winter and cool in summer.

Your goal should be to insulate your attic to R-38 if possible. This will help you avoid paying too much on energy bills throughout the year, as well as improve comfort levels inside your home. What’s more, if you plan on selling your house someday soon then investing in better insulation now could give buyers peace of mind that they’ll stay comfortable here long after they move out!

You can convert this value into inches by dividing by 3. Richfield Spray Foam Insulation

You can convert this value into inches by dividing by 3. For example, if your attic has an R-value of 25, you’ll have around 8 inches of insulation on the walls and ceiling. This is often a good starting point for DIYers who want to improve their home’s energy efficiency.

If you’re not familiar with R-values or don’t know how much insulation to add, it’s hard to know whether or not this is enough. But don’t worry: there are plenty of ways to find out what’s right for your situation!

Add these two values together and compare the total to what is recommended for your region.

The amount of insulation you need is dependent on the climate you live in. The amount of insulation recommended for each region is based on a minimum standard and may not be enough if you are trying to achieve zero energy savings. To find out exactly how much insulation your home should have, use the table below to determine what is recommended for your area.

When considering whether or not it’s worth it to add more than enough attic insulation to meet these standards, remember that there are other costs associated with this project. One common concern people express when discussing adding more attic insulation is that it’s difficult or expensive. However, these concerns may not be valid—installing extra insulation is usually less costly than paying utilities every month!

When finished, you should have between 11-22 inches of insulation in your attic based on where you live in Canada and whether you are upgrading or doing a whole home job

You should have between 11-22 inches of insulation in your attic based on where you live in Canada. If you are doing a whole home job, this will be the case. If you’re upgrading, it will be smaller—between 5 and 11 inches.

The reason for this range is that we all know there are different ways to insulate an attic—you can use blown-in cellulose or batts—and each method has advantages and disadvantages depending on what level of insulation your house needs (see below).

Conclusion

To recap, the best way to determine how much attic insulation you need is by measuring the depth of your existing insulation and comparing it to the national insulation standard. If you have existing attic insulation, measure the depth in inches and multiply by your attic area. Use a ruler or yardstick to measure the R-value of your existing insulation. You can convert this value into inches by dividing by 3. Add these two values together and compare them with what is recommended for your region.
