We show that the quantum reflection coefficient of ultracold heavy atoms scattering off a dielectric surface can be tuned in a wide range by suitable choice of surface and environment temperatures. This effect results from a temperature-dependent repulsive part of the van der Waals-Casimir-Polder-Lifshitz atom-surface interaction potential.
