E stands for emissivity.
If something is low-E, that means it reduces the amount of heat transferred through a surface. Radiance paint is applied to the interior side of exterior walls. It has microscopic particles that create the same kind of emissivity barrier as low-E windows, thus reducing the transfer of heat outdoors. ChemRex's paint can reflect up to 30 percent of radiant heat back into a room during cold weather, compared with regular paint's 5 percent reflection rate. In hot weather, it can block up to 30 percent of radiant heat from entering a room.
