If you are considering re-insulating the exterior walls of your home with RetroFoam insulation, you’ve probably wondered what it is made of.

This is a question we get asked a lot here at RetroFoam of Michigan and we like to answer it in a way that is easy for everyone to understand.

Below is a simple explanation of what RetroFoam insulation is and the makeup and properties of the injection foam. Or, if you enjoy reading highly technical documents, you can check out our product tech and safety data sheets.

What is RetroFoam Insulation?

RetroFoam insulation is an injection foam that is used to insulate enclosed cavities, like existing exterior walls and concrete block walls.

RetroFoam injection foam insulation creates an air barrier, which means it creates an air seal that block air movement into and out of the home. It also provides heat resistance. 

Both of these qualities help make the structure more comfortable and energy efficient.

Now, let's tackle what is foam insulation made of, more specifically, what RetroFoam is made from.

What is RetroFoam Insulation Made Of?

RetroFoam insulation is made from a tri-polymer blend dry powder resin.

As the resin mixes with a foaming agent and water in the trailer, it transforms into RetroFoam insulation. Initially having a shaving cream-like consistency, it will fill all the nooks and crannies and make its way between wires and pipes when injected into existing walls.

Upon curing, it transforms into a semi-rigid, plastic solid to become an effective product for re-insulating and air sealing existing and concrete block walls - reducing drafts, energy bills, and airborne noise.

Is Foam Insulation Safe to Have in Your Home?

We've answered what is insulation foam made of, but does that make RetroFoam safe to have in the home?

RetroFoam does not have an odor and there is no off-gassing when installed. It is hypoallergenic, non-toxic, and environmentally friendly, complete with a Class 1 Fire Rating.

RetroFoam insulation even blocks allergens and pollutants from entering the home through the exterior walls.
