System 100

The Versi-Foam System 100 Open Cell is a Class I foam with a density of approximately 0.75 pounds per cubic foot.  READ MORE

Hy-Flo Systems

The Versi-Foam Class I foam is also available in constant pressure systems where a consistent spray pattern is needed from start to finish. READ MORE

• How does closed cell Versi-Foam^® compare to fiberglass and cellulose?

More “traditional” insulating materials such as fiberglass and cellulose are less expensive upfront; however Versi-Foam® offers the better value in the long run. Versi-Foam® has a approximately twice the R value, provides an airtight thermal seal, resists moisture and mold, seals hard to insulate areas, adds structural stability, and more – leading to significant energy savings and an overall better return on investment.

• What sets Versi-Foam^® apart from other spray foam kits?

Our patented U-Control dispensing gun provides the user complete control of how much foam to dispense by how hard you pull the trigger on the applicator. The gun allows you to spray foam at a rate of approximately 6 pounds per minute, or so slowly that you can write your name with it. It is the key to a consistent spray pattern and surface texture. The metered spray pattern saves material and clean-up time.

• Is Versi-Foam^® waterproof?

Closed cell Versi-Foam^® Systems (all systems except for the System 100 OC) are water-resistant, but not waterproof. Minimal exposure to moisture will not affect closed cell foams; however the foam may be compromised if submerged under water for a period of time. The System 100 OC is an open cell foam and thus will absorb and retain water if exposed. Therefore the System 100 OC should not be used in areas where moisture may be present.

• Is Versi-Foam^® temperature sensitive?

Temperature is key in producing good quality foam. For the majority of the closed-cell Versi-Foam^® systems, ideal yield/expansion and adhesion will result when the substrate and chemical temperatures range between 60°F and 80°F. Medium and large sized Versi-Foam^® Systems come complete with temperature strips indicating chemical temperature. Consult the operating instructions for specific temperature requirements.

• Can I leave Versi-Foam^® uncovered?

By code, you are required to cover polyurethane foam with a 15 minute thermal barrier. A ½ inch of drywall is the most commonly used. For uninhabited areas, such as attics and crawlspaces that are accessed for maintenance only (not used for storage) you may use an ignition barrier in lieu of a thermal barrier. Contact RHH Foam Systems for recommended thermal & ignition barrier products.

• Do I still need to install a vapor barrier?

A vapor retarder of some degree is required on the warm side of the building assembly. A vapor barrier is defined as a Class I vapor retarder (perm rating less than 0.1) and can be achieved with sheet polyethylene (Visqueen). Versi-Foam^® closed cell foams will achieve a Class II (0.1< perm rating <1) or Class III (1< perm rating <10) vapor retarder rating, depending on the specific product type as well as the applied thickness. Building codes call out for different vapor retarder requirements (Class I, II or III) depending on the region of the country. Consult your local codes as to which level of vapor retarder is required in your area.

• Do I have to use the kit the same day it’s opened?

Only the System I kits need to be used same day. All larger systems may be shut down and re-used again. If the kit will be used infrequently, a weekly maintenance routine is needed to prevent gun and hose blockage. See the Operating Instructions for weekly maintenance instructions.

• Can I paint Versi-Foam^®?

Yes, once the foam is fully cured it can be painted with any product that is not heavily saturated in MEK (Methyl Ethel Ketone). This should not be an issue in products made for interior/household applications. Other than the MEK concentration, the type of paint you use should be determined by the easiest method of application (paint, spray, etc) and the desired finish.

• Can I inject Versi-Foam^® into a closed wall cavity?

Application to existing closed walls is not recommended due to the pressure created by expansion. Damage to drywall and plaster will occur if the cavities are overfilled.

• Are the tanks recyclable or refillable?

The Department of Transportation forbids refilling or recycling of tanks. Once completely emptied the tanks should be disposed of as normal industrial waste. A sanitary land fill is recommended.

• Are there any health hazards associated with Versi-Foam^®?

Versi-Foam^® does not contain any urea formaldehyde, VOC's, CFC's or Penta-BDE's. The use of proper Personal Protective Equipment (PPE) is required during application. Please see the MSDS and Operating Instructions for PPE guidelines.
