Wall Insulation

The U.S. Department of Energy reports that up to 40% of the energy cost of heating and cooling a structure is wasted by uncontrolled air leakage. ThermalGuard and DuraTite spray polyurethane foam insulation products by Rhino Linings can help seal those air leaks and insulate your building in one step. Two products in one means your HVAC unit has complete control over the air inside your building. This air sealing and insulating allows your unit to operate more efficiently and ultimately allows you to save money.

Rhino Linings spray foam insulation products are third party tested to ASTM standards and field tested for perfomance.

LEED Credits

The following are suggestions of how ThermalGuard might be incorporated into a project in order to achieve LEED credits. This list is by no means exhaustive. Please consult with the LEED Accredited Professional on your project to determine if ThermalGuard or DuraTite can be used to gain additional LEED credits.

LEED Credit Category – Energy and Atmosphere

Prerequisite 2 – Minimum Energy Performance
Requires the building to comply with ASHRAE/IESNA Standard 90.1-2004 or the local energy code, whichever is more stringent.

When ThermalGuard products are installed into a structure, the insulating and air sealing properties of the foam will provide an envelope that will facilitate the design of an efficient system.

Credit 1 – Optimize Energy Performance
Requires a reduction in design energy cost compared to the energy cost budget.

When ThermalGuard products are installed into your structure, it provides the building with a sealed envelope, allowing the designer to downsize HVAC systems and supply the required ventilation. ThermalGuard, when used with a whole building concept, can help achieve the 10 possible points.

LEED Credit Category – Materials and Resources

Credit 2 – Construction Waste Management
Requires recycling and/or salvaging construction, demolition and land clearing waste.

ThermalGuard contributes a significantly lower amount of waste materials by weight, tremendously helping the project reach the 50% to 75% target for diverting waste from the landfill.

Credit 5.1-5.2 – Regional Materials
Requires use of building materials and products that are manufactured regionally within a radius of 500 miles of the project site.

ThermalGuard products are manufactured in Carrolton, Texas and Richmond, Missouri.

Credit 6 – Rapidly Renewable Materials
Requires use of rapidly renewable products and materials (made from plants harvested within a ten-year cycle or shorter) for 2.5% of the total value of all building materials and products used in the project.

LEED Credit Category – Indoor Environmental Quality

Credit 4.1 – Low Emitting Materials: Adhesives & Sealants
Reduce the concentration of indoor air contaminants that are odorous, irritating and/or harmful to the comfort and well-being of installers and occupants.

ThermalGuard OC.5 & OC1 utilize water as the blowing agent or ThermalGuard CC2 uses 245fa, a Zero Ozone Depletion Potential and low Global Warming Potential blowing agent. All products meet the LEED maximum VOC content requirement of less than 50 g/L. 

Credit 6.2 Controlling of Systems – Thermal Comfort
Credit 7.1 – Thermal Comfort
Requires a thermally comfortable environment that supports the productivity and well being of building occupants.

ThermalGuard products can help a building comply with ASHRAE Standard 55-2004 by insulating and air sealing the building, which allows for controlled ventilation strategies that enhance uniform temperatures, humidity control and pollutant reduction. Without the sealing qualities of spray foam insulation, thermal comfort control and ventilation for individual occupants would be very difficult to achieve.

LEED Credit Category – Innovation & Design Process

Credit 1 – Innovation in Design
Provides design teams and projects with an opportunity to be awarded points for exceptional performance above the requirements set by the LEED Green Building Rating System and/or innovative performance in Green Building categories not specifically addressed by the LEED Green Building Rating System.

The superior performance characteristics of ThermalGuard products and their installation flexibility contribute to this credit in two ways. First, ThermalGuard allows easy installation in areas that do not allow simple installation of conventional insulation products. Second, ThermalGuard are guaranteed to perform to the stated specifications for the life of the structure.

The above are suggestions only. It is recommended that a complete review of the LEED Green Building Rating System be made prior to applying for the listed prerequisites and credits. The LEED System can be reviewed at
