NanoTech’s Nano Shield Roof Coating Provides 50% Reduction in Energy Use

Overview


The Nano Shield insulative roof coating system reflects solar radiation & insulates your roof.  These two shielding mechanisms save you thousands on your yearly energy bill by reducing energy consumption by more than 50%*.  See more details below.


Nano Shield Roof Coating


NanoTech is a material science company which develops new-to-the-world technologies in the fireproofing and insulation space. In early case studies, the Nano Shield roof coating provides more than 50% reduction in energy use.

The technology works by reflecting the heat away (emissivity) from the roof and reducing the heat transfer (thermal conductivity) into the house.*

Energy in the form of heat is transferred into homes by conduction through the walls, floor, roof and windows, with a majority of the thermal exchange happening through the roof. Reflective roof coatings work by reflecting the heat and UV away from the building. Nano Shield not only reflects, but also combines its reflective properties with one of the lowest thermal conductivity materials commercially available.

In essence, most of the heat trying to invade your house is reflected away from the roof and the remaining heat transfer is extremely low due to our high insulating power. The result is greater than 50% reduction in energy usage as demonstrate by our most recent case study.*


Spraying the Nano Shield


APPLICATION

Nano Shield is a spray on roof coating, applied as a liquid and naturally dries over 8 to 24 hours depending on the climate.  Roofing  operations can continue 1 hour after final coat.  The Nano Shield roof coating can be applied to various types of roofs including:

  • Asphalt

  • Modified Bit

  • Concrete

  • Single-Ply Membrane

  • Metal

  • And more…


The Case


The NanoTech team worked with ParaTex Roofing and Construction to coat a metal corrugated roof for Faith West Academy in Katy, Texas.  The coating was spray applied and achieved a 2mm thickness.

Climate


The hot season lasts for 3.8 months, from May 28 to September 23rd, with an average daily high temperature above 87°F.  The hottest day of the year is August 6th, with an average high of 94° F and low of 73°F.

The cool season lasts for 2.8 months, from November 30th to February 23rd, with an average daily high temperature below 68°F.

The calculated savings are based on yearly averages for homes in the region, basically the expected ramp up around houses in the neighborhood in the summer months, compared to the actual consumption with Nano Shield Applied to the roof.

*Technical Notes


Definition of emissivity and thermal conductivity.  Emissivity is the relative power of a surface to emit heat by radiation: the ratio of the radiant energy emitted by a surface to that emitted by a blackbody at the same temperature. Nano Shield has an emissivity rating of 0.94. Simply, Nano Shield is reflecting most of the UV and heat away from the structure.

The coating also has a very low thermal conductivity. Thermal conductivity can be defined as the rate at which heat is transferred by conduction through a unit cross-section area of a material, when a temperature gradient exits perpendicular to the area. Essentially, this is the heat transfer from the exposed side to un-exposed side. The coating has a K value of 0.017 Watts Per Meter Kelvin. As a reference, silica aerogel is rated at .02 which makes Nano Shield less thermally conductive than aerogel.

*Energy savings may vary based on the size of the building and other variables.  The calculated savings were based on this specific building.  More detailed case studies will be released as additional data comes in.
