ArmorFoam spray foam insulation reinforces walls and roofs, which extends the overall life of any structure and defends against violent storms as well as water damage.
ArmorFoam industrial spray foam works well for sealing foundations, pipelines, roofs and walls, and even flooring.
Spray Foam Insulation: The Essentials
Although spray foam has been in use for over 80 years, continual product innovation has seen the increased adoption of spray foam for both residential and commercial use. The accelerated growth of sprayed foam insulation in building construction has allowed the foam material to maintain it's position as the go-to material when it comes to providing thermal protection and insulation for both commercial and industrial projects.
But what is spray foam insulation, and are there different types available for diverse applications?
What is spray foam insulation?
Spray foam insulation is a two-part liquid material that hardens then insulates and air seals wherever it is applied. The material comes in two large 55-gallon drums – an iso and a resin (A and B side). These two liquids are kept separate until applied at the job site by a qualified, licensed spray foam installer. The two liquids travel up through a heated hose to the spray gun, where they are combined to create the foam. The foam expands within seconds to fill the cavity surface. Depending on the type of sprayed-in foam insulation used, closed-cell or open-cell, the foam expands between 40 and 100 times its size upon application.
Open Cell vs. Closed Cell Foam: Which Should I Choose?
Although closed cell and open cell foam, both insulate a home, they do it in different ways. Please read our article in which we answer the question and examine both open and closed-cell foam to help you pick the best product for your project.
The types of spray foam insulation
Product innovation over the years has seen the introduction of several different types of spray foam insulation. Primarily in residential and commercial construction, open-cell and closed-cell spray foam are used while high-density spray insulation is used as roofing foam in commercial or industrial construction. Open-cell sprayed-in foam insulation, a soft low-density material, is typically used for interior applications such as wall cavities, the underside of roof decks, attics, basement walls, and crawlspaces. The open cell structure of low density foamed insulation allows for moisture permeability to help contribute to the moisture management and bi-directional drying of the wall assembly.
Closed-cell spray insulation, a firm medium-density substance, can be used in exterior applications such as continuous insulation applications, as well as internal applications. This type of foam insulation has a higher R-value per inch, making it also suitable for small areas that require the highest possible R-value to meet building code requirements. Closed-cell spray foam's rigidity help rejects bulk water, making it a distinguished flood-resistant material.
The benefits of open-cell spray foam
As mentioned, open-cell foaming insulation is best suited for interior purposes, offering an array of advantages of traditional fibrous insulation substances. Benefits of open-cell foam insulation include:
- Allows for bi-directional drying
- Can provide long-term creep and seasonal movement
- Can be installed at a significantly more economical cost and target the same specified R-value.
- Is not considered a food source for mold
- Provides sound dampening qualities and is ideal for media rooms and studios.
- Lower installed cost, per square foot
The benefits of closed-cell insulation foam
While open-cell foamed insulation has many advantages over traditional insulation types, closed-cell sprayed-in insulation goes beyond to offer further advantages. Although closed-cell sprayed insulation foam has a higher cost, there are benefits that the substance offers, including:
- Ability to reject bulk water (closed-cell foam insulation is acknowledged as a flood-resistant component by FEMA.
- Can be applied at low temperatures (as low as 5°F)
- Adds wall racking strength as well as impact protection
- Higher R-value* per inch – more comfortable to accommodate high R-value* specifications in narrow spaces
- Lower vapor permeance (can be a Class II VDR)
- Higher bond as well as tensile strength

ArmorFoam 2.0 is a two component, closed-cell, liquid spray applied, low density, all water blown, rigid polyurethane insulation foam. It exhibits superior insulation properties compared to other conventional insulation material and meets the highest flame retardancy standards for construction materials. ArmorFoam is easy to apply and its fast reaction time allows the applicator to complete difficult jobs quickly.
ArmorFoam 2.0 closed-cell polyurethane foam yields a high R-Value and minimizes air and moisture infiltration. ArmorFoam 2.0 increases structural integrity, thereby extending the life of a structure. This product also contributes to a healthier indoor environment by controlling problems associated with vapor drive, such as inner wall condensation, mold and mildew development. ArmorFoam 2.0 expands during application to provide increased performance values by sealing the building envelope. Cured foam will not corrode steel up to 200oF (94oC).
ArmorFoam 2.0 should not be used for exterior applications as the sunlight will rapidly degrade foam. It should not be used where foam will stay submerged in water. On overhead applications, ArmorFoam 2.0 must be applied in multiple passes. Applicable codes must be strictly adhered to.

Apply with ArmorThane’s ACI4101 Plural Component Application System.
Applicators must recognize and anticipate climatic conditions prior to application to ensure highest quality foam and maximize yield. Ambient air and substrate temperatures, moisture, and wind velocity are all determinants of foam quality. Variations in ambient air and substrate temperature will influence the chemical reaction of the two components, directly affecting the expansion rate, amount of rise, yield, adhesion and the resultant physical properties of the foam insulation.
To obtain optimum results, ArmorFoam 2.0 should be spray-applied to substrates when ambient air and surface temperatures fall within a range of 55oF to 100oF. All substrates to be sprayed must be dry at the time of application. Moisture in the form of rain, fog, frost, dew, or high humidity (>85% R.H.) will react chemically with the mixed components, adversely affecting the polyurethane foam formation, dimensional stability and physical properties of the finished product. Wind velocities in excess of 10 miles per hour may result in excessive loss of exotherm and interfere with the foam surface texture, cure, and physical properties, and will cause overspray to drift. Precautions must be taken to prevent damage to adjacent areas from overspray drift.
ArmorFoam 2.0 must be spray-applied using approved equipment. Use a 1:1 ratio pump with appropriate material heaters, as required for individual application. The “B” Component must be agitated continuously during application. For more information, contact ArmorThane.
Cured product may be disposed of without restriction. Excess liquid A and B material should be mixed together and allowed to cure, then disposed of in the normal manner. Product containers that are “drip free” may be disposed of according to local, state/provincial, and federal laws.
Keep polyol drums out of direct sunlight. Store drums below 80oF (26oC). Open small bung slowly to relieve pressure. Do not agitate polyol drum. Welding or hot work should be completed before application of foam. Spray crews must wear appropriate personal protective equipment. Dispose of empty drum properly.

hazard if improperly used or allowed to remain exposed or unprotected. Each person or company engaged in the manufacture, production, application, and installation of polyurethane foam should carefully determine whether there is a potential fire hazard associated with such product in specific usage and utilize all appropriate precautionary and safety measures as outlined in local, state/provincial, and federal guidelines.
Polyurethane foam utilized as an interior insulation system must be protected by an approved 15 minute, fire rated thermal barrier and meet all local, state/provincial, and federal Building Code approvals.
