What is fiberglass insulation? Fiberglass insulation is a type of insulation that’s composed of sand and recycled glass. It is a man-made material and has a high surface area-to-weight ratio that makes it an ideal insulator for residential and commercial buildings. 

Does it itch? Have you ever heard you shouldn’t touch fiberglass insulation because it can make you itch? Nowadays, fiberglass insulation does not irritate the skin like it used to, and manufacturing it is more environmentally friendly than it used to be. 

Where can it be installed? Fiberglass insulation can be installed just about anywhere in your house other than in the basement. For your basement, you should consider closed cell spray foam insulation instead, which we can also install.

Does it offer soundproofing? Fiberglass is a great sound barrier and over time settles only slightly (2%-4%) compared to cellulose. All JM fiberglass insulation is specifically designed to absorb noise that can be transmitted through walls, & ceilings.

Where does it work best? Johns Manville Climate Pro® loose-fill fiberglass insulation is made for installation in open attics to fill hard-to-reach areas like corners, edges and around framing.

What other benefits does it offer? Fiberglass insulation is a cost-effective way to insulate your home. Not only could you see some savings on your heating and cooling bills, but it can also help reduce noise pollution. It is also non-combustible and non-absorbent. It also has a great R-value. R-value stands for “resistance value” and it measures an insulating material’s resistance to heat flow. The higher the R-value, the greater the insulation power that material has.

Best Residential Insulation for Cold Climates

Here in Minnesota, our climate is undeniably cold. When the summer is over and winter sets in, it gets downright frigid. High-quality insulation is therefore needed to keep homes comfortable not only in the summer but during the winter as well. The right insulation can keep a home safe and heating bills down. But, what types of insulation are best for this cold climate? As the trusted name in insulation including cellulose insulation for St Michael and the surrounding areas, we’ve put together a list of the top choices in insulation for our climate no matter the time of year.

Before we go into what types of insulation are best for northern climates, we must first talk a bit about the R-Value. It is a metric that stands for the insulation material’s resistance to heat flow. The type of insulation and its R-Value that is needed depends mostly on where you live. In our case of Minnesota, the higher, the better. The general rule is that the higher the R-Value, the better the insulation material.

Blown-In Cellulose Insulation

Blown-In cellulose insulation that has an R-Value of 49 is the best for cold climates. It is effective at all temperatures but can perform even better during cold periods. It’s the best to use in ceilings, open new wall cavities, unfinished attic floors, or other such hard-to-reach places.

Spray Foam Insulation

Spray foam insulation also has a higher R-Value. It can even help eliminate some other tasks, such as caulking since it also forms an air barrier when it settles. It starts as a liquid, and it expands to fill all the available space, thus sealing cracks, gaps, and air leaks. 


For cold climates, loose-fill fiberglass insulation has a great R-Value too. It will also not lose its energy-saving capabilities over time. It is non-combustible, non-corrosive & non-absorbent. If exposed to moisture, fiberglass will not hold water. We install high-quality JM fiberglass insulation. When you have us upgrade your insulation needs with JM fiberglass insulation, you can expect year-round comfort.

All three of these solutions work best for our cold climate in Minnesota and here at Lewis Insulation, we supply all three! Not sure which one to choose? Allow our experts to help you select what will work best for your home.

The Many Benefits of Spray Foam Insulation

Is your home’s air conditioning already working on overdrive? If your insulation is out of date or inadequate, you may be fighting a losing battle. Newly installed, higher-quality insulation can help lower your heating and cooling bills and one of the best insulation options out there is spray foam insulation. Plymouth area residents love this type of insulation because of its high R-value and its ability to help save them some money on their heating and cooling costs. Here are a few more reasons to love closed cell spray foam insulation.

Here at Lewis Insulation, we offer closed-cell polyurethane spray foam insulation. It is one of the most advanced insulating materials available today in the construction industry. We use state-of-the-art equipment & have completed certified training & continued education on spraying polyurethane spray foam.

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.

And, because closed-cell spray foam insulation won’t allow 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.

Spray foam insulation can help increase your home’s structural integrity and help keep birds, insects, squirrels and other pests 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.

There are many different ways closed cell spray foam insulation can benefit you and your family!

Cellulose Insulation Keeps Your Home Cooler in Summer

It’s getting warmer and warmer and before we know it, summer will be here. Is your home’s insulation working to keep your home cool? If your air conditioning unit is doing all of the work, it’s time to consider better insulation. What happens when you crank up the AC and it’s still uncomfortably hot? Are there rooms in your house that you avoid during the summer? If so, then it’s very likely that you need to update your insulation.

Commercial Spray Foam Insulation

Many people think insulation is only important during the colder seasons, but the need for proper home insulation applies to hotter summer months as well. Insufficient attic insulation allows the summer heat to permeate into homes. This is why it is very important to check attic insulation as the first step in troubleshooting a home that does not stay comfortably cool, or has extremely high electric bills during the summer months. Here at Lewis Insulation, we specialize in insulation installation including cellulose insulation for Wayzata and the surrounding areas. We can help get your insulation where it needs to be for the summer months ahead.

The most important place to start is the attic. When the summer sun beats down continually on your roof, hot and cold air tends to behave differently than it would in the colder, winter months. As we all know, attic insulation, helps to keep the home feeling comfortable.

Cellulose insulation is one of the best options to use in the attic since it offers superior sealing properties compared to fiberglass batts or rolls. Blown-in cellulose insulation provides a thick layer of insulation that provides great comfort to your home. Cellulose insulation is also plant fiber-based; perfect for wall and roof cavities to insulate, draught-proof and reduce free noise. And, since it is made of recycled plant fibers, it is safe for the environment and your wallet. 

If you’ve been having concerns about your attic’s insulation, our highly trained specialists are just a call away. Whether you’re completing a remodeling project or building a new home, our experienced team can help.

Give us a call today to learn more about how we can help your home stay warm in the winter and cool in the summer. For more information on cellulose insulation in the Wayzata area, call Lewis Insulation at 763-477-2612 or you can contact us for a Free Estimate.

Things You Can Do to Keep Your House Warm All Winter

Do you brace yourself every time you open your heating bill? If so, your house may be too cold and drafty and you’re paying far too much to heat it. Luckily, you can make some changes that will help keep your house warmer and save you money over time. As the trusted insulation contractors for Rogers and the surrounding areas, we’ve put together just some of the ways you can make your house not only cozier but more energy efficient. 

Insulation Contractors Rogers

Have a programmable thermostat. A programmable thermostat will allow you to preset temperatures for different times of the day because you don’t need to keep your home at the same temperature around the clock. You can choose a setting on the low end when you’re sleeping or are away and go with a higher setting at other times. This way, with a programmable thermostat, there’s no chance you’ll forget to adjust it. 

Move furniture away from heating vents. Sometimes without realizing it, a couch, chair or bed can block the flow of heat into a room. This wastes money and leads to cold rooms. With a forced-air system, blocking a supply or return vent can cause a house-wide pressure imbalance that disrupts the heat flow in the whole system.

Change furnace filter. This is something many homeowners forget. If you have a forced-air system, changing the furnace filter can save you some energy and keep dust down in the house.

Seal door gaps. Cut down on areas cold air can enter your house, like under a door to the outside. Seal any gaps underneath doors leading to the outside with a fabric “door snake.” You can also keep the heat where it’s needed by making sure some interior doors, such as those leading to hallways or near stairways, are kept shut.

If you feel cold air seeping beneath a door leading outside and find that using a door snake is inconvenient, install a draft-defeating nylon door sweep.

Use your drapes. Open them during the day to get free solar heat and then close the curtains just before sunset. Also, consider insulating curtains.

Properly insulate. The correct, properly installed insulation can help make your home not only more comfortable but more efficient as well. It can even help reduce noise pollution and reduce moisture and more.
