Frequently Asked Questions
What is the difference between open cell and closed cell foams?
Closed cell insulation also adds structural integrity throughout the wall system. Tests by the National Association of Home Builders Research Center in 1992, 1996 and 2005 show that spray-applied foam between wood and steel stud wall panels increase rack and sheer strength two to three times more than traditional stick-built components with fiberglass insulation when sprayed on to gypsum wall board and vinyl siding. The tests also showed that closed cell foam also increased racking strength when sprayed on to oriented OSB.
Open cell foam, on the other hand, should only ever be used for interior applications. Open cell foams are more cost effective per unit of R-value than closed cell foams, but do not provide buildings the additional structural support that closed cell foams do.
Please work with your local Rhino Linings approved contractor to determine which product works best for your specific application.

How do spray foam insulation products from Rhino save consumers money?
In many cases with new construction or large-scale retrofits, you can save additional money by reducing the required size of the HVAC (heating and air conditioning) unit because ThermalGuard and DuraTite create a continuously sealed thermal envelope around your home or structure. You might also be able to reduce or eliminate the use of other building materials when you use foam such as soffit vents, ridge vents, attic ventilation fans, radiant barriers or vapor retarders.
How do spray foam insulation products from Rhino control indoor air quality and comfort?
A well sealed envelope gives the HVAC system and your ventilation system full control over the clean filtration and amount of fresh air entering the structure. This helps to maintain great indoor air quality by blocking and filtering out harmful foreign irritants such as mold, pollen or other allergens.

Is spray foam insulation safe?
Typically, for the applicator this would include wearing a respirator, solvent-resistant gloves and protective clothing. The zone where protective equipment is required can vary depending on the amount of open space and free ventilation. For example, fumes dissipate rapidly outside of a few feet on a rooftop, while in an enclosed room, fumes and mists can build. Each job should be assessed and a safety plan developed specific to the application by the installer. Rhino Linings approved contractors are all expertly trained in proper safety procedures.
How long should I be out of my building if spray polyurethane foam is being installed?
In addition to the release of airborne SPF chemicals during spray application, certain components can be liberated from newly-installed SPF products for a short period of time following installation. Always check with your contractor, because they will be familiar with your specific situation. As a rule of thumb, we recommend 24-48 hours before occupants re-enter the building.
Will Rhino spray foam insulation products burn?
Polyurethane foams are combustible materials, which means that they will burn in the presence of a flame. Flame retardants are added to the product to help ensure that they meet or exceed the all of the applicable building code requirements. Always refer to the fire testing for each product and make sure it meets the specific requirements of your project.
