The Myths of Radiant Barrier (Pt. 1)

For years, many have relied on radiant barriers to boost the energy efficiency of buildings. Yet, there are still numerous misconceptions about how radiant barriers works, how easy it is installing a radiant barrier and the benefits they bring. In part 1 of this blog, we will dispel some of the most common myths about radiant barriers, installing radiant barriers, and provide accurate information about their effectiveness.

MYTH: Radiant barriers only work in hot climates

FACTS: Radiant barriers are effective at reducing heat transfer in all climates.

In the summer, radiant barriers work by reflecting the sun’s radiant heat away from the building’s roof or attic. This diminishes the amount of heat the building absorbs, making it easier to maintain a cool interior. Consequently, there is a noteworthy reduction in the amount of energy needed to keep the temperature comfortable inside the building. This leads to lower energy bills.

In the winter, radiant barriers function differently. They reflect the heat generated by the building’s heating system back into the building, preventing it from escaping through the roof or attic. This maintains a warmer interior, decreasing the amount of energy required to sustain a comfortable temperature inside the building. Consequently, this leads to lower energy bills.

Radiant barriers achieve temperature control by reflecting thermal radiation, which keeps surfaces cooler in the summer and warmer in the winter. This reduces the energy required to maintain a comfortable temperature inside the building.

MYTH: Radiant barriers are difficult to install

FACTS: Radiant barriers are actually quite easy to install, making them perfect for DIY projects.

The most common installation method involves using adhesives or staples to attach the radiant barrier directly to the underside of a roof or the walls of an attic. Alternatively, you can install them with a layer of air or another insulating material between the surface and the barrier. You can accomplish this by installing the barrier on furring strips or utilizing spacers.

You can install radiant barriers in new constructions or incorporate them into existing buildings. They prove versatile, finding application in roofs, walls, and floors. You can also combine them with other insulation types like fiberglass or foam to further enhance energy efficiency.

Without a doubt, radiant barriers are an easy-to-install, versatile, effective solution for improving the energy efficiency of a building.

MYTH: Radiant barriers are only effective when installed on the roof

FACTS: Radiant barriers can also be installed on walls, floors and other surfaces to improve the overall energy efficiency of a building.

In buildings with extended exposure to direct sunlight, consider installing a radiant barrier on walls for particularly effective results. This can be common in buildings with large windows or glass facades, which can allow a significant amount of solar heat to enter the building. By installing a radiant barrier on the walls, you can reduce the amount of heat that enters the building. This helps in keeping the interior cooler and reduces the need for air conditioning.

Consider installing radiant barriers on floors, particularly in buildings with crawl spaces or basements. This can help to prevent heat from escaping through the floor, which can be a significant source of energy loss in some buildings. By installing a radiant barrier on the floor, you can reduce the amount of heat that escapes. This helps to keep the interior warmer and reduces the need for heating.

Collectively installing radiant barriers on walls, floors, and other surfaces proves to be an effective method for enhancing a building’s energy efficiency. This practice reduces heat transfer through these surfaces, thereby decreasing the energy required to maintain a comfortable interior temperature. This leads to lower energy bills and contributes to a more environmentally friendly building.

MYTH: Radiant barriers are only effective for a short period of time

FACTS: Radiant barriers are designed to provide long-lasting benefits to a building’s energy efficiency.

The durable materials of radiant barrier make it resistant to wear and tear and allow it to withstand exposure to the elements. As a result, they can continue to provide energy savings for many years.

In addition radiant barriers are typically installed in areas that are not easily accessible, such as the roof or attic, where they are less likely to be damaged or disturbed. This means that they can provide long-term benefits without requiring frequent maintenance or replacement.

Overall, radiant barriers are a simple and effective way to reduce heat transfer and improve the energy efficiency of a building. By clearing up misconceptions about their effectiveness, we can help more people grasp the advantages of using radiant barriers and make informed decisions about enhancing the energy efficiency of their buildings.
