Non-Uniform Effectiveness: The effectiveness of radiant heat barriers varies depending on factors such as roof pitch, orientation, shading, and the presence of obstacles.

The radiant barrier will block the radiant heat transfer between a surface that is giving off heat, such as a hot roof, and a surface that can absorb this heat, like conventional attic insulation.

For example, I’ve seen studies that show radiant barriers can reduce heat gain through R-19 insulated ceilings by more than 40 percent, which is true. But that doesn’t mean your bill goes down ...

The radiant barrier will block the radiant heat transfer between a surface that is giving off heat, such as a hot roof, and a surface that can absorb this heat, like conventional attic insulation.

CF NBR insulation material also efficiently reduces heat loss for hot water plumbing, liquid heating and dual temperature piping. CF NBR Self-Seal Tube / Sheet Insulation is also CFC/HCFC free, ...

The effectiveness of radiant heat barriers lies in their ability to reflect radiant heat. When exposed to the sun, windows, walls and roofs absorb a significant amount of solar radiation.
