Create Freedom from Outrageous Energy Bills with the Help of Attic Spray Foam Insulation

Monthly energy bills increase every time the furnace or air conditioner kicks on. Michigan homeowners with poor attic insulation are seeing their expensive air, the air they pay to heat or cool their house, escape right through the attic.

Updating that old attic insulation with spray foam not only gives your furnace and air conditioner a break from constantly running, but makes families happy with reduced monthly energy bills and the avoidance of other annoying problems like condensation, mold, and ice dams.


Replacing Your Old Attic Insulation with Superior Spray Foam Makes A Huge Difference

Reduced Energy Bills

Keeping the conditioned air in and the outside air out improves energy efficiency, reduces the carbon footprint, and puts more money back in your pocket.

Comfortable Living Space

Foam insulation provides the necessary air seal to keep indoor temperatures consistent across all the rooms of your home all year, no matter the season.

Healthy Home

Less dust, allergens, and condensation leading to mold and mildew entering your home will make the whole family happy, not just those with allergies.

A More Efficient Home is in Your Future

Spray foam insulation provides the critical air seal that keeps the cold air in your house in the summer and the warm air in your house in the winter - providing a more energy-efficient, comfortable, and healthy home.


Insulating Your Attic with RetroFoam of Michigan

Over the past 17 years, we’ve insulated thousands of existing homes with foam insulation. Our consultative project managers, highly skilled crews, and helpful office staff aim to guide you through the process with ease. Not to mention, our lifetime warranty gives your family access to our family long after the job is complete.

Removing Old Attic Insulation

For the spray foam to work properly, your old fiberglass or cellulose attic insulation will need to be removed. Our removal crew will roll up old fiberglass insulation and place it in large garbage bags, or vacuum out cellulose with industrial size vacuums to ensure the area is all cleaned out and ready for spray foam. This is a challenging job that our specialized removal crew makes simple by removing and disposing of your old insulation.

Spraying the Attic Roof Deck vs. the Attic Flat

When insulating an attic with spray foam the roof deck or the flat (floor) can be insulated. When the roof deck is insulated the attic becomes a semi-conditioned space, no longer has extreme temperatures throughout the year, and is great for storage. If there are high peaks or a connected garage that shares the attic, it may be best to insulate the attic flat. During your estimate, your estimator will explore these options with you and recommend the best solution for your home.

Frequently Asked Questions

Does old insulation need to be removed from the attic before spray foam can be installed?

The old insulation in your attic should be removed before the spray foam is applied. This is done so the spray foam can get into all of the nooks and crannies creating an air seal in your attic. Learn more.

Can pests nest in spray foam insulation?

Spray foam is not inviting for rodents and other pests to nest in compared to materials like fiberglass and cellulose. The air seal foam creates also helps to block those air leaks critters are looking for to find a way in. Learn more.

Will spray foam retain water and lead to mold and mildew problems if my roof leaks?

One of the benefits of using a premium open cell spray foam is that it doesn’t retain water. It also doesn’t promote mold and mildew growth. Learn more.

Should I insulate the roof deck or flat of my attic?

This really depends on what you plan to do with the space. If you include your attic in your building envelope by insulating the roof deck, then you can use the space for storage, as well as prevent ice dams. Insulating the attic flat cuts it off from the rest of the home’s conditioned space. Learn more.

Will spray foam fix my very hot attic?

Spray foam insulation on the roof deck can help combat that hot attic. This is because the attic has now become a conditioned part of your living space. Learn more.

Is open cell or closed cell spray foam better for my attic and roof?

Both open cell and closed cell spray foam create the air seal you're looking for in your attic. While open cell spray foam is what is usually recommended, there are instances where closed cell makes the most sense. Learn more.

How much does spray foam cost in the attic of an existing home?

The cost to insulate an attic can vary greatly depending on the size of the area to be sprayed and the material used. The range to insulate the attic is between $5,000 and $10,000. Learn more.

Does mold remediation need to happen before spray foam is installed in the attic?

The short answer is no but spraying foam insulation over mold isn't the magic cure you're hoping for. Spray foam will kill mold because of the air seal it creates, but there's a lot more to consider. Learn more.

Is a vented or unvented attic better for my home?

Choosing the attic system that is best for your home really comes down to what you want to use the space for and how your home is designed. If you want storage space and no risk or moisture, the unvented is the way to go. If you have a high-pitched roof, then vented is a better bet. Learn more.

How much money can you save by insulating your attic?

You can save between 15 to 50 percent by insulating your attic if it is the only area of your home leaking air. There is more to consider though than just this one area. Learn more.
