Thermal Insulation Data
How It Works


Nansulate® coatings are a patented insulation technology that incorporates a nanocomposite called Hydro-NM-Oxide, a product of nanotechnology. This material is documented as having one of the lowest measured thermal conductivity values. Nansulate®, when fully cured, contains approximately 70% Hydro-NM-Oxide and 30% acrylic resin and performance additive.

Thermal conductivity, k, is the intensive property of a material that indicates its ability to conduct heat. The lower the thermal conductivity number, the better the insulator. The low thermal conductivity of Nansulate® and the nanomaterial contained in Nansulate® is what makes it an excellent insulator.

Nansulate® technology has been tested by several accredited independent laboratories.
Below are some of those tests which show reduction of thermal transmission.


Independent Laboratory Testing

Standard Test Method for Steady-State Thermal Performance of Building Assemblies

(UNI EN ISO 8990:1999 - similar to ASTM C236)

Description: Two wall samples are tested according to test standards for a variety of thermal measurements including thermal flow, thermal conductance and thermal resistance. The sample sizes are 120x120x10 cm (approx. 4 ft x 4 ft x 0.3 ft) and they are tested at a mean temperature of 15 deg. C (59 deg. F). One wall sample is non treated, meaning it is plaster + normal water-based paint. The other wall sample is plaster + 3 coats of Nansulate® translucent coating.

Testing was done by the accredited laboratory Istituto di Richerche E Collaudi - a certifying body for the Italian Government.


Thermal transmission, measured in watts, through the wall section coated with Nansulate® was reduced by 34.80%

Thermal resistance (1/U), measured in m2*k*w1, of the wall section coated with Nansulate® was increased by 28.98%

ASTM E1530 - Standard Test Method for Evaluating Resistance to Thermal Transmission

Description: Two concrete substrates are tested at different temperatures. One is coated with 2 coats of Nansulate® Crystal roof coating and one is uncoated. thermal conductivity is tested for each.

Testing was done by the ISO certified laboratory Anter Laboratories, Inc.


Thermal transmission, measured in Btu/h ft F through the concrete substrate coated with Nansulate® was reduced by an average of 29.7%


Thermal Testing Data


ISO 8301/ASTM C518 - Thermal Conductivity at 0 deg C (32 deg F)

Description: Three glass substrates are tested at freezing temperature (heat conducts more slowly at colder temperatures). One is coated with 4 coats of Nansulate® Energy Protect, one is coated with 8 coats of Nansulate® Energy Protect, and one is uncoated. Thermal conductivity is tested for each.

Testing was done by the accredited laboratory Norner.


Thermal conductivity, measured in W/mK through the glass substrate coated with Nansulate® was reduced by 10% at a 4-coat coverage, and by 33% at an 8-coat coverage at freezing (0C/32F)

Case Studies

Of course actual real world energy saving data is just as powerful, and in some cases even more so, to illustrate how an insulation is performing after installation, and over time.
Below are a few of our real world energy saving case studies:

Location: Oklahoma
Energy Savings achieved in the 3-years Post-Nansulate: 46%

Cure Time

Note about cure time. Nansulate® has a cure time of 30-90 days (dependent upon humidity, environment and number of coats used). The typical cure time for a 3-coat coverage in ambient conditions is 30-days, where the typical cure time for a 10-coat coverage at ambient conditions can be up to 90 days. During the cure time the excess moisture (which conducts heat) is dissipating/curing from the coating, and as this happens, the thermal performance of the coating is improving. Do not expect to obtain any significant thermal readings if you are testing the coating before the cure time has completed.

If you plan to conduct your own studies of Nansulate's thermal resistance, you must allow the coating to cure completely before full thermal abilities can be expected to be measured accurately. See our FAQ for more information on this as well as the proper thermometers to use.

Nansulate® has been throughly tested by a number of accredited laboratories, universities, corporations and individuals. Intererested individuals are free to conduct their own testing as they see fit, however please understand that we cannot provide technical assistance on test methods created by individuals which may not be scientifically sound.

Why Thin Film Insulators Do Not Have an R-value:

This is common question, and to understand the answer, you need to understand where the R-value came from.

The R-value was lobbied to congress mid-20th century by fiberglass insulation manufacturers as an easy way to express thermal values to consumers, by using a single number (i.e. R-5, R-13), rather than the more complicated thermal conduction values. This method is based upon insulation that is meant to be used at an inch or more thick and favors that type of insulation.

Because the R-value uses thickness as a large part of the final number calculation, it cannot accurately be used to reflect insulating and thermal conduction values of insulation technologies meant to be used at less than an inch thick.

It's a case where the measurement standard has not progressed as fast as the technological innovations.

This is why we have used thermal testing that measures direct heat conduction in energy units (such as watts), that is not dependent upon thickness. These types of tests measure the ability to insulate and reduce thermal conductivity, no matter how thin or thick a material is.

One of these is the European Union Standard for thermal performance of building assemblies, which you'll see in our available downloads. Reviewing this test, and others that we have available, you'll see that Nansulate® is an excellent insulator, and its insulating value is expressed in reduction of heat transmission in actual energy units.
