New material reflects light, reduces cooling energy needs

Scientists have created a new building material that could change how buildings are cooled. This porous plastic sheet reflects 96% of light, reducing the need for energy-intensive cooling systems. The material, made from powdered polymethyl methacrylate, offers better cooling than existing options by reflecting both visible and infrared light. Tests showed it kept temperatures significantly lower than traditional materials. The sheets are inexpensive, recyclable, and can help reduce environmental impact in areas facing rising temperatures. This development adds to other innovative materials being explored for sustainable construction.
