FAQs about Insulation

Did you know that May is National Home Remodeling Month? In honor of this yearly event, we thought we would take the time to answer some of the most frequently asked questions that we get about residential insulation and all of its benefits. And the next time you are tackling this type of home improvement project, give the professionals at Lewis Insulation a call!

Q: I see a lot written about insulation’s R-value. What is that and why is it so important?

A: In basic terms, R-value measures the insulation’s resistance to heat flow. So the higher the R-value of that insulation is, the greater the insulating power it will have. The R-value is generally determined by the type of insulating material, the thickness and the installed weight per square foot.

Q: What are the benefits of having a properly insulated home?

A: The biggest benefit you will probably see is a decrease in how much money you spend heating your home in the winter and keeping it cool in the summer. But you will also enjoy a few other benefits! The biggest ones are a decrease in the amount of mold and mildew that can sometimes build up in your attic and other crawl spaces, as well as a decrease in the amount of outside noise that you hear in your home.

Q: How do you determine what type of insulation I should have installed?

A: Our insulation contractor will take several different things into account. The R-value of the insulation, how big your home is, the climate and a few other factors are taken into consideration.

Q: Why should I hire insulation contractors to install new insulation? Why can’t I just do it myself or have a general home contractor do it for me?

A: Professional insulation contractors, like the ones at Lewis Insulation, are properly trained and certified in the best and most safe and effective ways to install insulation in your home. We have knowledge of the ins and outs and smaller details of this type of work that general contractors might not have.

The Importance of Insulation in the Summertime

When some people think of insulation, they assume it’s only important when they need to keep their homes warm in the winter. But insulation also serves plenty of other purposes. It can help reduce the amount of outside noise you hear in your home, and it can also help keep your home cool in the summer. We are insulation contractors in St Paul and the surrounding areas, and we can think of several reasons you should make sure your home’s insulation is in tip-top shape for the upcoming hot summer months.

Summertime does get hot, but as the saying goes: “it’s not the heat, it’s the humidity.” That humidity can get trapped in your attic (because heat rises), and the humidity and heat need somewhere to go once they reach your attic. Otherwise, your entire house, not to mention you and your family, can get uncomfortably hot. So to counteract that heat and humidity, you might end up running your air conditioner much more than you would have otherwise, which could lead to higher cooling bills and a shorter lifespan for this expensive appliance.

Proper insulation and ventilation play a key role in making sure this heat and humidity do not build up in your attic. Ventilation is what helps get rid of the heat and humidity, and it draws them out of your home. Insulation is what helps to keep the heat from the sun from entering your home in the first place. The heat can transfer from your roof and down through the ceilings into the main living areas of your home. Insulation contractors like us can come to your home to install the best kind of insulation that will help keep your home comfortable year-round. We can be sure the insulation we install will help keep your home comfortable no matter what the weather outside is like.

There are a few different factors our insulation contractors will look at when deciding on what kind of insulation is best for your home. We can go over your options with you so you make an informed decision, and that way you can rest easy knowing your home will stay cooler this summer and you might end up seeing some savings on your cooling bill!

The Advantages of Fiberglass Insulation

There are many different reasons fiberglass is such a popular choice in insulation material. Not only is it cost-effective, but the installation process is also usually pretty quick. We specialize in fiberglass insulation in Maple Grove, so here are a few other reasons fiberglass is a great choice.


Fiberglass insulation is a budget-friendly option for many homeowners. You still get many of the same perks as other types of insulation, but fiberglass is one of the least expensive options on the market today.

Easy to Install

You will not have to wait long for fiberglass insulation to be installed. While the installation process can be easy, it is still best to call in the professionals, like the ones at Lewis Insulation, to get it installed. That’s because if someone without a lot of experience installs your fiberglass insulation, it can be installed improperly and you could lose a lot of the benefits of this insulation.

Not Too Flammable

Fiberglass is made out of sand and recycled glass, so that means it does not catch fire that easily. If it is under direct flame, it will melt, not burn. Fiberglass insulation is not a fire hazard.

Increases Energy Efficiency and Reduces Noise

Fiberglass insulation can help increase the energy efficiency of your home. It helps to slow the spread of heat and cold by trapping pockets of air. This helps keep your home cool in the summer and warm in the winter. Plus, it helps the amount of outside noise that comes into your home.

Mold and Mildew Resistant

The type of fiberglass insulation we install is mold and mildew resistant. So you will not have to worry that your new fiberglass insulation is retaining moisture and possibly causing more harm than good to you and your family.

Improves Indoor Air Quality

Your home’s indoor air quality is very important to the health and well-being of you and the rest of your family. Fiberglass insulation can help improve your home’s indoor air quality because it helps reduce mold and mildew growth.


Because fiberglass insulation is made out of renewable resources, like sand and glass, it is an eco-friendly choice for those worried about the impact of their carbon footprint.

What Type of Attic Insulation is Best?

There are several different types of attic insulation out on the market today, and all of them have their benefits. We install attic insulation in Plymouth, and we specialize in three different kinds: closed cell spray foam, fiberglass and cellulose.

Spray Foam Attic Insulation

Closed cell spray polyurethane foam (SPF) is a premium insulation perfectly suited for the building envelope. With a high R-value, it acts as a barrier to keep the indoors from the outside climate, creating thermal, air and moisture isolation.  It can expand and reach hard-to-till voids that other insulation types are not able to do.
Closed cell spray foam is easy to use and fast to install when done correctly. It will not shrink or settle, and it lasts the life of a structure. You should see some long-term savings on your heating and cooling bills with closed cell spray foam insulation in your attic.

Fiberglass and Cellulose Attic Insulation

The two other types of attic insulation we install are fiberglass and cellulose attic insulation. These types of blown-in insulation have almost the same R-value, and they are both environmentally friendly. Cellulose is made out of recycled newspaper and fiberglass is made out of sand, both of which are renewable resources.

These types of insulation are great for filling in gaps and ensuring your entire attic is evenly insulated. The installation process is generally pretty quick, depending on the size of your attic. They are tighter fitting types of attic insulation too, which means they’re good at reducing noise pollution.

Fiberglass and cellulose attic insulation are also very energy efficient, so you should see some savings on your heating and cooling bills in the long run with this type of insulation too.

If you aren’t sure what type of attic insulation is best for your home, give us a call. We can advise you on which type will best suit your needs and keep your home warm in the winter and cool in the summer.

How to Choose the Best Insulation for Your Home

When you need insulation for your home, figuring out where to start can be confusing. As home insulation experts in St Paul, we help homeowners like you every day. You know you need new home insulation and you know how important it is for keeping your heating and cooling costs down. But how do you know what type of home insulation is best? Lewis Insulation installs three kinds: fiberglass, closed cell spray foam and cellulose. Here is a rundown of what to think about when choosing home insulation.


Home insulation R-values measure the insulation’s ability to resist heat flow. The higher the R-value, the better that section of insulation is at keeping heat from passing through it. You should take this number into consideration when choosing home insulation. Closed cell spray foam offers the highest R-value on the market, so this is the more budget-friendly option over the long term.

Current Home Insulation

Where do you need new insulation? Do you need it all over your house or just in the attic? How long ago was your insulation installed, and what is its R-value? How does that number compare to today’s industry standards? Keep in mind that your attic, basement, crawlspaces, garage, exterior walls and exterior floors should all be fully insulated. There are a lot of things to think about! But we can help here at Lewis Insulation! We can talk to you about the most up to date home insulation on the market today and which one will best suit your insulation needs.

Insulation Installation

While some might consider installing home insulation as a do it yourself project, we recommend hiring professionals like us for the job. Not only do we know exactly what we are doing, but we have all of the tools and safety equipment to ensure the job is done safely and properly.


Having a budget in mind is important. But remember the old adage that you get what you pay for. Spending a little bit of extra money now could pay off in the long run. The better the insulation, the better it is at helping your home be more energy efficient. And that could help you save money on your heating and cooling bills in the long run.
