Owlfly YELLOWJACKET™ Insulation
Owlfly YELLOWJACKET™ insulation uses cutting-edge thermodynamic technology to provide some of the best insulation on the market -
and we can prove it.
YELLOWJACKET™ is American-made, lightweight, water-resistant, non-combustible, non-toxic, non-dusting, irritant-free, and made from recycled materials. And – best of all – YELLOWJACKET™ is ASTM certified as more energy-efficient than nearly all competing brands.
YELLOWJACKET™ can be installed as wall batts between studs, or as large panels outside the structure for both new construction and energy-efficiency retrofits. Whatever your next project entails, YELLOWJACKET™ insulation is a great choice for you.

All insulation reduces the flow of thermal energy (or “heat”) from one surface to another. Insulation keeps the heat in during the winter and out during the summer. The same fundamental physics apply to all types of insulation. There are three main types of heat transfer: conduction, convection, and radiation.
YELLOWJACKET™ Insulation is made from a lattice of special air pockets, which are carefully engineered to minimize convective heating. A low-emissivity coating is applied to internal surfaces to eliminate most radiative heating, and the walls of the pockets are thin enough to mitigate conductive heating. In every way, YELLOWJACKET™ Insulation is a simple and efficient choice for all your insulation needs.
While researching wasps for her first book, Chris Alice Krater realized that the nests of Arctic Yellowjackets (Dolichovespula albida) could be used as inspiration for a breakthrough in insulation technology.
Arctic Yellowjackets build spherical paper nests in cavities within permafrost high above the Arctic circle. Chris was amazed that these little wasps could survive in such extreme conditions. As it turns out, the nests are protected from the frost by a layer of carefully-engineered air pockets within the paper structure that surrounds the nest – and the thermal properties of that structure was previously unknown to science.

Chris pitched the idea to RIT's chapter of Engineers for a Sustainable World in 2019. A team led by Ben Ocamb researched the premise and developed a simple prototype for the 2019 Biomimicry Design Challenge through the Biomimicry Institute, but the team was unable to perform thermal testing to validate their results.
2020 - 2021
In 2020, Chris continued the project through Owlfly LLC under the direction of thermal engineer Olivier Montmayeur. For the next year, the team worked through extensive thermodynamics testing and modeling, including constructing a custom heat transfer test rig to quickly analyze and compare materials. The initial tests showed promise, so the team iterated the prototype design until it compared favorably to market alternatives. It just seemed right to name the product after the wasp that inspired it.
The Owlfly team pursued grant funding and private investment to build production equipment to bring YELLOWJACKET™ to market. Automation engineer Zoey Katz joined the team to improve Owlfly's in-house manufacturing capability with custom robotics.
