Radiant Barrier Savings
A precise tool.
What is the Radiant Barrier Savings & How does it work?
Radiant barriers are reflective materials that reduce heat transfer through roofs, walls, and floors by reflecting infrared radiation rather than absorbing it.
The effectiveness of a radiant barrier is measured by its emissivity ((e)), which should be as low as possible. A typical value for an effective radiant barrier is 0.1 or lower.
Savings = text{Annual Heating Cost} times left(1 – frac{text{Emissivity}}{2}right)
e = Emissivity of the radiant barrier

Frequently Asked Questions
How do radiant barriers work?
Radiant barriers reflect infrared radiation, reducing heat transfer through roofs, walls, and floors.
What is the ideal emissivity for a radiant barrier?
The ideal emissivity for an effective radiant barrier is 0.1 or lower.
How do I calculate my annual heating cost savings with a radiant barrier?
Multiply your Annual Heating Cost by (1 – Emissivity/2) to estimate savings.
Can radiant barriers be used in any climate?
Yes, radiant barriers can be beneficial in both hot and cold climates by reducing heat transfer.
Do radiant barriers require maintenance?
Regularly check for damage or dirt buildup to maintain their effectiveness.
Are there different types of radiant barriers?
Yes, common types include foil-faced kraft paper, reflective insulating paint, and bubble wrap.
How long do radiant barriers last?
Radiant barriers typically last 15-20 years with proper installation and maintenance.
