Radiant Barrier

[rthitoff]

I have come across some homes with spray on radiant barriers. I live in a 30 yr old doublewide in Houston Texas area. The insulation is not real good. I saw some tiny ceramic powdery type stuff at paint stores that you put in paint, and spray interior or exterior, and I was wandering if someone has had any experience with this stuff. Or any other suggestions. The light bill gets pretty high in the summer.

Thanks Rick

Hi Rick

If you go to the attics and insulation forum you will find one titled (smoke and mirrors you decide ),that mike put out for members to read.Hopfully you will find this helpful.

Spray-in radiant barrier is very tough to make work with the effective numbers it talks about in brochures.

Spray-on product must have a smooth surface and must be applied up to two coats to even approach a 70% effective rating.

Most roof decking (bottom side in attic space) is "not" smooth.

I can put you in contact with a manufacturer's rep , based in Houston who can provide you with some additional information.

I can also put you in contact with a few inspectors in the Houston market who can also share data with you.
