Today you ll learn about the benefits of radiant barriers and insulation and how both can reduce heating and energy costs.
It works differently than other types of insulation.
Radiant barrier insulation can reflect up to 97 of radiation and reduce attic temperatures dramatically.
Osb radiant barrier sheathing can reflect up to 97 of radiation and can significantly reduce attic temperatures.
Radiant barriers can be installed alongside insulation in the attic space providing a heat shield that can lower cooling costs in the summer months.
The radiant barrier resulted in roughly 4 times more savings than the added insulation.
