Reflective insulation is great for reducing heat in the summer or keep heat in during the winter. Cut with scissors to fit windows and use small pieces of Velcro to hold in place. If you find the need to remove frequently, try using a fishing line and tape for hanging. Use small Command stick hooks to hang in place. Reflectix insulation is available on Amazon, but Lowes has a larger quantity for a cheaper price.
This also works great for lining any outer walls inside your cabinets. Have you ever noticed on a hot day when you open cabinets how hot they are inside even though your rig is cooled down? Adding Reflectix will help reduce heat.
