I’m impressed with the information available in this forum! I hope and pray I don’t degrade the quality of interchange.
Anyway, my question is whether anybody has had experience with homeowner installing a foil radiant barrier inside the attic on the underside of the roof rafters to reduce attic temps? Does such a thing actually work or is it only effective if reducing cash in wallet?
As I understand it, between each roof rafter, there would be a 5 1/2" air space between the barrier and the roof deck. Also, attic has no soffit or ridge vent, but has (4) mushroom vents along the upper roof, I guess 8" to 10" round, and two gable vents that are about 9"x 18" each.
Would the heat that is “reflected” out of the attic stay in the roofing and degrade the shingles? I wouldn’t want to reduce attic temps at the expense of ruining the roofing. Thanks for your input! This would be a Michigan installation.
