Just like a space suit, HeatBarrier XP reflects the sun’s heat before it can warm up the insulation in your attic. When the insulation stays cooler, your house will stay cooler. NASA used this technology in space to protect our astronauts. The space suit with its reflective layers kept the astronauts body cool in extreme heat and warm in extreme cold.   Thermos bottles keep hot things hot and cold things cold. They are almost perfect insulators. The tight seal and air space prohibit heat transfer by conduction and convection. The reflective surfaces inhibit radiation heat transfer. If the bottle starts out hot, it stays hot because very little heat is transferred to the cooler outside. If it starts out cold, it stays cold because very little heat is transferred from the warmer outside.
