Why Use Radiant Barriers for Attic Insulation?

Radiant barriers help by reflecting heat away from your home, which keeps your attic—and ultimately your living spaces—cooler in the summer and keeping heat in during the winter. This is especially beneficial during summer months when excessive heat gain from the attic puts more strain on your air conditioning system. The Super R® Plus Radiant Barrier is ideal for those looking for professional-grade performance, while the Super R® Diamond Radiant Barrier offers an easy-to-install, DIY-friendly solution with perforations to prevent moisture buildup.
By choosing the right radiant barrier, you can reduce heat transfer, leading to significant energy savings and improved comfort throughout the year.
Key Benefits:
- Lower cooling costs by up to 15-20%
- Reduce heat transfer and improve indoor comfort
- Increase the lifespan of your roof and equipment by lowering attic temperatures

Energy Savings and Comfort
Installing a radiant barrier in your attic is an effective way to improve your home’s energy efficiency and comfort. By reflecting heat away from your attic, radiant barriers reduce the amount of heat entering your living space, making it easier to maintain a consistent indoor temperature. This leads to less reliance on air conditioning and heating, especially in warmer months, which can result in significant energy savings—often up to 20%. In addition, keeping your attic cooler reduces the strain on your HVAC system, potentially extending its lifespan and lowering maintenance costs.
