Benefits of RetroFoam Insulation

RetroFoam is the Home Insulation Solution You Can't Find Anywhere Else in Denver

REDUCE DRAFTS

RetroFoam gets into the cracks and crevasses other home insulations can’t. By doing so, it decreases drafts that seep through the voids in your walls.

SOUND DAMPENING

You will definitely notice a decrease in outside noise, but please understand that your home will not be entirely deprived of outside noise.

DETER RODENTS

Deter rodents and insects from wanting to come through and burrow in your walls because the cavities will now be full of RetroFoam insulation.

HOME HEALTH & SAFETY

RetroFoam is a biodegradable, eco-friendly product that has no off-gassing and is Class 1 Fire Rated, providing a safe environment for your family.

What Can Be Insulated with RetroFoam?

RETROFOAM INSULATION IS USED IN ENCLOSED CAVITIES

We primarily use RetroFoam to insulate existing exterior walls to keep out drafts and improve the building envelope.

RetroFoam can also be used for interior residential or commercial walls for sound dampening purposes. Although it does not offer a completely soundproof solution, it can help to decrease sound greatly.

We can also inject RetroFoam into the core of CMU block in residential and commercial settings.

RetroFoam's fire rating also makes it a great option to fill king studs and steel beams for fireproofing purposes.

RetroFoam Install Process

Our install process makes it easy for the homeowner because our aim is to work from the outside of the home so you're not disturbed on the inside. A couple of key factors to consider is the age of the home and the building materials associated with the construction of your home.

Regardless of your home’s age and building materials, our aim is to leave as little footprint as possible and deliver a great install experience.

Check out the video to see our process first hand, and read more details below.
Vinyl, Aluminum, Steel, or Hardie Board Siding
If you have siding like vinyl, aluminum, steel, or hardie board, we will take a strip down near the middle of the wall and drill into your stud cavities. After that, we will probe the cavities left and right, up and down, to make sure that we are filling everything in the whole cavity. Upon completion, your siding will be put back into place. 

For vinyl siding, you shouldn't even be able to tell we were there. For Aluminum, hardie board, or steel siding, it may require a bit of touch up paint from the homeowner where we cut caulking.

If we come across a fire block, we will remove another strip of siding on the other side of the block and repeat the same process of probing to ensure there's not another cavity. There are times when we find three and four cavities in a wall, up and down, depending on the construction of the home. Once we've filled this cavity with our foam, we're able to plug it and put the siding back on.
Wood Siding
If you have wood siding or composite siding, where nails are driven through the surface of each plank, you will need to use paint to touch up the areas where those nails are and where we had to cut the caulking on the sides. However, we will take care of the re-caulking and getting everything put back in place for you.
Brick Exterior
If you have a brick exterior, we use a five-eighths inch drill bit to drill into the mortar area in each cavity. We typically drill three holes per stud cavity so that we can ensure we've filled the whole cavity. After we fill it with our foam, we'll put the mortar back in to match the exterior of your home as close as possible.
Installing RetroFoam from Inside the Home
We can work from inside the home if you prefer this method for a specific reason. For example, maybe you have some kind of a stucco exterior that you don't want tampered with in any way. We can certainly come through and work from the interior of your home as well to keep the exterior of your home preserved.

Please understand that if we do work from the interior of your home, you're going to have two-and-a-half inch holes in every cavity, which equates to one hole every 16-inches. And if we find blocking up and down that cavity, we're going to have to drill additional holes to make sure these other cavities are filled properly.
  • "RetroFoam installers were on-time, professional, and friendly. The difference this foam has made is more than noticeable! Before the installation, our south wall was so cold in winter that the butter in the cupboard would be too hard to spread! Now all the rooms and cupboards on that entire side are comfortable, and we even don't hear outside noise anymore."

  • "Immediate outside noise reduction! We have no doubt there will be energy savings as well! The crew was excellent! We had one weak spot that split on our drywall so they sent a drywall crew out and did a perfect patch job. VERY PLEASED!"

Frequently Asked Questions
Will I be able to get back into my wall if I need to repair something?
If you need to get in there and take out the insulation for whatever reason, you can do that with your bare hands. It does not have the adhesive, it's not sticky, it's not hard. This is a malleable foam, specially designed so you can take this out and you can work with it if you need to.

How do you know if the cavity is fully insulated after injecting RetroFoam?
Our teams have infrared cameras we use to look inside the walls and inspect them as we're filling them with RetroFoam. This technology allows us to show you, on a camera, that your walls have been properly filled.

Can RetroFoam be installed with pre-existing insulation?
If you have old insulation in your walls, that’s perfectly fine. RetroFoam will seep around the old fiberglass or cellulose and fill the cavity full.

How long does it take to install RetroFoam?
The installation process can usually be completed in a day unless specific circumstances require us to work an additional day.
