During the winter months 50-75% of your homes heat loss through the ceiling or roof and 60-85% of heat loss through your walls is radiant. In the hot summer months up to 93% of heat gain is radiant. By installing a radiant barrier in your home, your heat loss will be less in the winter and your heat gain will be less in the summer, saving money on your energy bills. This will also allow your HVAC system to work less and help prolong the life of your units.
Add Radiant barrier on the underside of your roof deck. Radiant barrier can lower your attic temperature by 30 degrees, improve HVAC duct performance up to 50 % (duct work and A/C unit is not subjected to the extra heat of the attic), is permeable, dose not trap moister, has low emissivity, has high reflectivity, improves efficiency of insulation and will save 10-15% on cooling cost. The foil type reflects 98% of solar radiation (spray on 80%).
Spray on radiant barrier products Don't Work. So why would anybody use them. Why! From what we see high pressure sales and gimmicks to make a fast buck. Spray on radiant barrier is not a good substitute for foil. It only blocks 60 to 78% of radiant heat at best, if installed 100% correctly, which never happens. It is not considered a radiant barrier by energy Star or the Government. It comes off to the touch and over time. It causes aluminum dust that often infiltrates to the living area of the home. It also cost just as much and often more than the foil, which blocks 98% of radiant heat. I know, I have used both in my home. Foil works, spray on does not!
The above improvements will pay for themselves over time and are the most relevant to Comfort and Energy savings.
