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.

The Benefits of Closed Cell Spray Foam Insulation

Closed cell spray foam insulation can be a Minnetonka homeowner’s best friend. Not only does this type of insulation offer one of the highest R-values on the market today, but it is also a great way to possibly help save some money on your heating and cooling costs. Here are a few more reasons we love closed cell spray foam insulation.

Enjoy High R-Value and Cost Savings

As we mentioned already, closed cell spray foam insulation has a very high R-value. R-value measures a material’s resistance to heat flow. So the higher the R-value, the better the material is for insulation purposes. And if your house’s insulation has a high R-value, that could translate into savings for you. You could save money on your utility bills because your spray foam insulation is doing such a great job keeping your home warm in the winter and cool in the summer.

Reduce Allergens and Noise

Because closed cell spray foam insulation will allow very little moisture into your home, this also means that dust and other allergens are less likely to enter your home too. This could lead to better health for you and your family, especially for those who have allergies. Closed cell spray foam insulation is also a great way to help reduce the amount of outside noise that enters your home. This is especially beneficial for those who live near a busy road or a similar area.

Reduce Mold Growth

Tying back into the previous paragraph, because moisture will not be allowed to enter your home through the closed cell spray foam insulation, mold and mildew will be less likely to grow. And that means these might not be as much of an issue for you and your house. A reduction in mold and mildew growth could also benefit any allergy sufferers in your home too!

Increase Structural Integrity

Closed cell spray foam insulation can help increase your home’s structural integrity, and it can also help keep birds, insects, squirrels and other pesky critters from nesting in your home. In the long run, this could help you avoid pests like termites, which could cause a great deal of damage and require expensive repairs.

As you can see, there are many different ways closed cell spray foam insulation can benefit you and your family!

The Importance of Attic Insulation

Have you given your attic’s insulation any thought lately? As experts in attic insulation in St Paul, this is something we think about on a daily basis. Insulation is the best way to make sure your home stays toasty warm in the winter and comfortably cool in the summer. Here are a few other tidbits to keep front of mind about attic insulation.

  • If you use your attic for storage purposes only, it is not necessary to insulate the attic itself. Just make sure the attic floor is fully insulated so warm air stays where you want it the most – in the rooms of your home and not up in the attic. The same goes with cool air too.
  • About 25% of heat is lost through your attic. Heat escapes out of the roof of the attic thanks to poor insulation.
  • Take the time to find out when the last time you had attic insulation installed. New insulation should be put into your home every couple of years because insulation tends to compress. And that decreases its effectiveness.
  • When you have new attic insulation installed, make sure your attic is still properly ventilated. If you hire professional insulation installers like us, we will make sure your attic has the right amount of ventilation so it does not lose heat.
  • After you have new attic insulation installed, do not walk on it unless it is absolutely unavoidable. And do not store anything on it either, no matter how light the object may be. This will help the attic insulation work properly for as long as possible.
  • If you have a finished attic that is used for living space, it should be insulated like all of the other rooms in your home.
  • The proper attic insulation could help you save money on heating and cooling bills and increase the comfort level of your entire family.
  • In order to figure out the correct attic insulation for your home and in order to save as much on your heating and cooling bills as possible, you should consult insulation experts like the ones here at Lewis Insulation. We offer closed cell spray foam, cellulose and fiberglass insulation.
