Do you dread the yearly rise in your energy bills when summer comes around? Does your home often still feel uncomfortably warm even though you’re paying what feels like a fortune to run the air conditioning? A possible solution to those summertime heat woes is to install radiant barriers in your home’s attic.
Radiant barriers work along with insulation for homes that have their HVAC systems in the attic. In the peak summer heat, your attic can get up to 120 degrees. Those high temperatures put major stress on your HVAC system, which not only lowers the efficiency of the unit, but can also shorten its lifespan.
To better understand how radiant barriers help keep your home cool, you first need to know how heat is transferred into your home. Heat is transferred in three ways: conduction, convection, and radiation. In conduction, heat is transferred through direct contact, whereas in radiation, it transfers through electromagnetic waves.
When the sun hits the roof of your house, it is radiant energy that is making the roof hot. That radiant energy is then conducted through the material of the roof into your attic space. Once that energy has reached the interior of your attic, it then radiates down onto anything present on the attic floor, including the HVAC system.
Radiant barriers work by creating a controlled space around the HVAC unit, protecting it from the radiant heat coming from your roof. This helps the unit operate more efficiently, which not only saves you money on your energy bills, but also helps extend the life of your HVAC unit. Talk to a professional to see if radiant barriers are a good fit for your home!
