Coldrays

It's time for cooling that works with nature, not against it. Coldrays was founded with a commitment to redefine the way we approach energy-efficient solutions for a sustainable future. We are proud to be America's first large-scale distributor of passive daytime radiative cooling (PDRC) materials, including films, membranes, and fabrics. These cutting edge materials reflect incoming sunlight and release heat into the cold of space with no electricity, no water, no fossil fuels, and no emissions. All that's needed is a clear view of the sky above. Our products enable the following: - Buildings with roofs that cool themselves under noon time sun, reducing cooling demand by as much as 30%. - Outdoor shade structures that keep our loved ones safer from intense summer heat by reducing roof and subsurface temperatures by 12°F or more. - Dairy farms that reduce their cooling water and electricity usage by 40% or more by creating an entire micro-climates in and around barns, milking parlors, calf housing, and other structures. - Buses and trucks that are kept cool by innovative physics rather than fossil fuels. Reducing demand on the vehicle's air conditioner can increase fuel efficiency by up to 5%. - Disaster relief tents that stay cooler and more comfortable without any energy, especially when power grids are strained or down. In testing, tents made of PDRC fabric stay significantly cooler than those made of traditional white fabric. - Passively cooled warehouses and self-storage that keep stored goods more protected from the damaging effects of heat. - More comfortable off-grid RVs and cabins with reduced air conditioner and generator demand. And much more... Our goal is to jumpstart the passive daytime radiative cooling (PDRC) industry in the United States by distributing the equivalent of 500 megawatts of PDRC in by 2030. United by innovation and inspired by our planet, join us in cooling our world to secure a better future for those who come next.
