Home Insulation: Important Facts That Homeowners Should Remember

By: John Garcia | Date Posted: January 10, 2023

Insulating your home is a great way to save energy and money. It can reduce air leakage, increase comfort, and lower your monthly utility bills. But it’s important to remember that not all insulation systems are created equal. Depending on the climate you live in, you may need different types of insulation for the best performance.

Why Should Homeowners Insulate Their Homes?

Home insulation helps keep your home warm in the winter and cool in the summer. It reduces heat loss or gains through walls, ceilings, and floors which helps maintain comfortable temperatures inside your house all year round. This results in lower energy bills by increasing the efficiency of heating/cooling systems as well as making rooms more comfortable when temperatures outside change drastically.

What Are the Different Types of Home Insulation?

#1: Spray Foam Insulation

Spray Foam Insulation

This type of insulation is applied as a liquid and expands to fill the space it’s sprayed into. It’s great for irregularly-shaped spaces or tight spots where other insulation materials may not fit. Spray foam is also airtight, making it an excellent choice for preventing air leakage and drafts.

#2: Fiberglass Insulation

Fiberglass Insulation

One of the most popular types of insulation is made of fiberglass. It is cut to size and inserted between wall studs, floor joists, ceilings, and other surfaces around your house. It is available in rolls and batts. With this kind of insulation, heat transmission from external sources, such as chilly weather or scorching summer days, is effectively reduced.

#3: Cellulose Insulation

Cellulose insulation is made of recycled paper products and other natural materials. It’s generally more eco-friendly than traditional types of home insulation, such as fiberglass. This type of insulation is resistant to moisture, and its packing properties make it great for filling small crevices between walls or floors.

What Is R-Value?

The R-value of an insulation material indicates how well it resists heat transmission. The resistance to heat passage through a substance increases as the R-value rises. To achieve energy efficiency criteria, the majority of construction codes stipulate that walls and ceilings must have R-values of at least 19 and 21, respectively. Compare various R-values when choosing your insulation material to find the one that will perform the best.

Important Facts To Know About Home Insulation

Important Facts To Know About Home Insulation

#1: It Saves Energy

Insulating your home will help reduce energy usage and save you money on monthly utility bills. How can it save you energy? Insulation acts as a barrier to keep cold air in during the winter and hot air out during the summer.

#2: It Requires Professional Installation

It Requires Professional Installation

Insulating your home is not a DIY project! You should always hire a professional contractor for the installation of insulation materials. Insulation professionals like iFoam know exactly what type of material will work best for your home and climate, so it’s important to get advice from an expert before purchasing any insulation material.

#3: It Can Increase Comfort

Insulation helps maintain more consistent temperatures throughout the year, making your home comfortable during both hot summers and cold winters.

#4: Different Insulations Are Best For Different Climates

The type of insulation that works best in your area depends on the climate and how much protection from heat transfer is needed. Be sure to research which materials are most effective in your region before purchasing insulation for your home.

#5: Different Areas Of The House Need Different Types Of Insulation

The walls, floors, and ceiling of your home may need different types of insulation for the best performance. Be sure to check with a professional contractor about which materials are best for each surface before installing insulation in your home.

While there are Facts, there are also Myths…

Myth #1: It Is Only Necessary For Hot Climates

This is not true! Even in colder climates, insulation can be beneficial for reducing energy costs and creating a more comfortable environment.

Myth #2: It Requires A Lot Of Maintenance

Home insulation does not require much maintenance after it has been installed. Some materials may need to be replaced over time if they become damaged or worn out, but regular upkeep should not be necessary.

Myth #3: Loose-Fill Insulation Is Less Effective Than Other Types

Loose-fill insulation can actually provide better coverage than other types of insulation due to its ability to fill small spaces and crevices that traditional materials may miss. In some cases, loose-fill insulation may be the most cost-effective option as well.

To sum up, insulation is an important part of energy efficiency and comfort for any homeowner. Knowing the different types of insulation available, how they work, and which type works best for your climate can help you make the best decision when selecting materials for your home. Also, remember that proper installation is key to ensuring your insulation performs optimally. With these facts in mind, you can make sure you get the most out of your investment in insulation.
