Attic insulation vs radiant barrier.

Radiant barrier installed right under the roof radiant barrier insulation isn t meant for soundproofing or keeping warm air from leaking up into the attic and out of the house. Reduced temperature of insulation results in less heat transfer into the conditioned space of the home source. Today you ll learn about the benefits of radiant barriers and insulation and how both can reduce heating and energy costs. This is because foil insulation reduces radiant heat gain rather than slowing conductive and convective heat flow.

Radiant barriers are not the same as insulation. This in effect will reduce the amount of radiant heat that leaches into your home from your attic making is less comfortable for you and your family especially in the warmer months. That means the home will be more comfortable and the efficiency of attic insulation and the ac system will be improved. If installed on top of attic floor insulation the foil will be susceptible to dust accumulation and may trap moisture in fiber insulation so it is strongly recommended that you not apply radiant barriers directly on top of the attic floor insulation.

It works differently than other types of insulation. Osb radiant barrier sheathing can reflect up to 97 of radiation and can significantly reduce attic temperatures. Radiant barrier insulation can reflect up to 97 of radiation and reduce attic temperatures dramatically. The radiant barrier resulted in roughly 4 times more savings than the added insulation.

The cost to do it myself was roughly the same in both cases so the resulting roi was 4 times faster for the radiant barrier. When installed correctly a radiant barrier can provide a notable difference in attic and insulation temperatures especially in the summertime and in warmer climates. Radiant barriers can be installed alongside insulation in the attic space providing a heat shield that can lower cooling costs in the summer months.
