Is A Radiant Barrier Necessary With Metal Roof

Why is radiant barrier the smart insulation option for metal buidings.

Is a radiant barrier necessary with metal roof.

The roof absorbs radiant heat from the sun but air flow either wind or attic ventilation has a cooling effect on the roof and helps bring down the overall temperature. The cooler a roof is the less radiant heat it emits. Much of this heat travels by conduction through the roofing materials to the attic side of the roof. The radiant barrier should be installed in a manner to minimize dust accumulation on the reflective surface.

In theory if your roof never got any hotter than the outside air temperature then a radiant barrier would not be needed. When it comes to insulating metal building homes you have many different options. Thank you for your help on this and all you have given us over the years. A radiant barrier can lower heat transfer from attics to the building below keep the attic space cooler and lower cooling costs by up to 17 in warmer climates.

We take a look at how radiant barriers work the different types of radiant barriers and some of the. We ve discussed some of the best insulation options for metal buildings but most people agree that radiant barriers should be a part of the building s insulation if energy efficiency is a goal. When the sun heats a roof it s primarily the sun s radiant energy that makes the roof hot. Our main house has a barrier and it is a great help in cooling.
