Attic insulation is one of the primary home improvements that can increase the efficiency and overall performance of a home, for those here in Charlotte that are looking to reduce their energy costs and stay comfortable all year round. But if you already have attic insulation and are wondering if you could also benefit from a radiant barrier installed under your roof, a trusted insulation and radiant barrier installation contractor will have all the information you need. And that’s exactly what we’re here to do! Here is what you should know about installing a radiant barrier with attic insulation

Understanding Radiant Barrier Insulation

Radiant barriers are composed of a highly reflective aluminum material that creates an enclosed airspace inside the attic. The purpose of a radiant barrier is to slow down or prevent radiant heat transfer by intercepting the heat that would otherwise penetrate the roof and radiate down into the attic and living spaces below. In winter, they also help to retain the heat inside the home, making them a year-round solution.

Maximizing Existing Attic Insulation

Attic insulation, such as fiberglass or cellulose, primarily works by reducing conductive heat transfer. It acts as a barrier to slow down the movement of heat through the attic floor. While this type of insulation is essential, it doesn't always effectively address radiant heat transfer. If you have attic insulation but your home is prone to large amounts of radiant summer heat, adding a radiant barrier will result in the following benefits:

Improved Energy Efficiency 

A radiant barrier complements insulation by reducing the amount of heat that enters or escapes through the roof. This can significantly reduce the workload on your HVAC system and ultimately lead to lower energy bills.

Enhanced Home Comfort

If you have attic insulation and still experience consistently higher temperatures on the second floor, it could be an indication of heat radiating into the attic space. By installing a radiant barrier, you can help maintain more even temperatures throughout your home, reducing hot spots and improving overall comfort.

Extended HVAC System Lifespan

By adding a radiant barrier to your attic, you can alleviate some of this stress by reducing the heat load on your system. As a result, your HVAC equipment may last longer and require fewer repairs, saving you money in the long run.
