Radiant Barrier Insulation - What It Is and Why You Need It

Greenshield Insulation • January 4, 2025

Understanding Radiant Barrier Insulation


Radiant barrier insulation is a type of insulation that reflects radiant heat, rather than absorbing it. It is typically installed in attics where it can drastically reduce the amount of heat that penetrates the home. The barrier is comprised of a thin sheet or coating of a highly reflective material, usually aluminum foil, which is applied to one or both sides of a number of substrate materials.


The radiant barrier insulation works by reducing the amount of heat that is transferred from the roof of the house to the other areas of the house. It can be especially beneficial in sunny climates and during the summer months when the sun is beating down on the roof.


The Magic of Reflective Heat


What sets radiant barrier insulation apart from other types is that it primarily handles the radiant heat from the sun. This is important because radiant heat is the heat you feel emanating from a hot stove or the warmth you feel on your face when you stand near a window that's been heated by the sun. Traditional insulation, like fiberglass and cellulose, is good at slowing conducted and convective heat but is less effective at slowing radiant heat. The radiant barrier insulation, with its reflective properties, excels in this area.


The Impact on Energy Consumption


One of the primary reasons homeowners choose to install radiant barrier insulation is because of the potential for reduced energy consumption. When the temperature inside the attic is lowered, it means the house's air conditioning system doesn't have to work as hard to cool down the home. This can result in significant energy savings. According to the U.S. Department of Energy, radiant barriers can reduce cooling costs by 5% to 10% in hot, sunny climates.


Radiant Barrier Insulation and Comfort Level


Not only does radiant barrier insulation help with energy consumption, but it also helps boost the comfort level inside the home. By reflecting the scorching sun rays back towards the source, your home stays cooler during the hot summer days. It is a solution that works round the clock, providing comfort for everyone in the house.


The Professional Touch


While the installation of radiant barrier insulation might seem like a simple task, it actually requires a great deal of precision and expertise. If not installed properly, the radiant barrier can lose its effectiveness. At Greenshield Insulation, our specialists have the necessary expertise and experience to ensure a flawless installation, making your home as energy-efficient as possible.
