Spray Foam Insulation in Andover MN | What is spray foam insulation made of?
Isocyanates are a family of chemicals made up of molecules that easily react with others. They are known for their low molecular weight, but are still sturdy enough that they are used in the manufacture of flexible and rigid foams, fibers, paints and varnishes—and increasingly in the automotive industry.

The polyol resin is a chemical that’s used in the production of spray foam insulation. Polyol resins can be made from either natural or synthetic materials. The most common are ethylene and propylene glycol; however, other materials such as pentaerythritol and butanediol may also be used. Polyol resin is known for being a versatile chemical that easily reacts with other compounds to create a variety of different products. It can be used as an adhesive, sealant or binder for coating materials such as fiberglass and concrete.
Polyurethane, a polymer made of organic units, is the most common material used for spray foam. It’s made from two main ingredients: isocyanates and polyols. The reaction between these two compounds forms the foam that’s used in spray foam insulation. Polyurethane combines the flexibility of Isocyanates with the versatility of Polyurethane.
Spray foam insulation comes in two styles: open-cell and closed-cell. Open-cell spray foam uses a type of polyurethane that has many small holes in it, giving it an open-cell structure. This allows for air to flow through the material and prevents moisture from getting trapped inside. It’s a little more flexible than closed-cell compositions, but it’s also more susceptible to punctures and tears.
Closed-cell spray foam uses a type of polyurethane that has fewer holes, giving it a closed-cell structure. This makes it more rigid and less susceptible to punctures than open-cell compositions. This type of structure is great for adding more support to your home. Closed-cell spray foam is much less likely to be affected by moisture than open-cell compositions, which makes it a good choice for insulating exterior walls. It’s also more resistant to mildew and mold growth because of its waterproof nature. Additionally, it’s enhanced structural support makes it an excellent choice for exterior walls.
Spray foam is a great choice for insulating exterior walls because it’s waterproof. The spray foam seals all cracks and holes in your home where moisture could get in and cause damage. This makes it much less likely that water will penetrate the interior of your house. It also helps prevent mold or mildew growth on the surface of your siding, which can cause significant damage to your home if left unchecked.
Spray foam is a great choice for insulating exterior walls because it’s fire resistant. The spray foam helps prevent the spread of fire by forming an effective barrier that stops flames from reaching your home’s interior. This can be an important safety feature if you live in a wildfire-prone area or have a wood-burning fireplace. The thermal resistance of spray foam also helps keep your house cool during the summer months by reducing air infiltration and heat loss through the walls.
Spray foam also provides excellent structural support, which can be especially helpful if your home has been damaged by a storm or other natural disaster. The insulation helps prevent moisture infiltration and reduces the likelihood of mold growth, making it easier to repair any damage caused by water intrusion. In this way, spray foam insulation provides structural support in two ways: by adding extra support to your home’s walls, and by preventing structural damage from water and other sources.
