Does Sheet Aluminum Reflect Heat

Physics i ve been wondering if something that was polished to a mirror finish was better at not absorbing heat through light than something painted with pure white paint.

Does sheet aluminum reflect heat.

Ryerson offers heat treatable aluminum sheet grades like the popular 6061 aluminum alloy that can be used for commercial applications that require strength corrosion resistance and machinability as well as non heat treatable grades when formability and weldability are priorities. By placing this sheet of metal around the heat source it will reflect back the thermal radiation created by the heat source and block much of the thermal convection. Just as wearing light colored clothing can help keep you cool on a sunny day cool roofs material that is designed to reflect more sunlight and absorb less heat than a standard roof. A fireplace heat reflector can reflect heat into your room.

What is fireplace reflector. A radiant barrier reflects heat radiation radiant heat preventing transfer from one side of the barrier to another due to a reflective low emittance surface. In building applications this surface is typically a very thin mirror like aluminum foil. It will perform well in all climate types including excessive heat cold or moisture so that you have an all purpose barrier that meets the needs of your property.

A corrugated metal fence can reflect sound. The foil may be coated for resistance to the elements or for abrasion resistance. By covering one side of window sized cardboard panels in reflective aluminum foil and placing them behind the window treatments next to the windows shiny side facing outdoors you can stop at least some heat from entering the home explains ready gov. At the same time since metals are good thermal conductors we should be careful that the metal does not come into direct contact with the heat source.

Cool roofs can be made of a highly reflective type of paint a sheet covering or highly reflective tiles or shingles. What s more effective at reflecting heat a sheet of aluminum that is polished or a sheet of aluminum painted white. A simple fireplace reflector is a stainless steel sheet held vertical to your fireplace floor by metal fireback supports. If needed use duct tape to join cardboard sheets or pieces together for large windows.

Most metal sheets are lightweight and easy to install. It will reflect the sunlight and retain the heat.
