Just started looking into radiant barrier for the attic (I live in
Texas!). Has anyone had this installed, does it work and have you
noticed a difference?


Where the heat flow is downward as from a hot roof to a room ceiling below
(mainly by radiation) they can be pretty helpful. Good for hot summer
conditions. In the winter, when heat flow is upward (mainly by convection)
they are questionable.

I once had good results laying kitchen style foil wrap between the rafters
in the attic above a bedroom. The bedtime ceiling temperature was very
noticeably reduced and the room was much more tolerable without air
conditioning.
