As an HVAC contractor who has spent many hours in attics installing A/C systems I am very skeptical of how good of an installation of radiant barrier can be done in an existing home. I've been in the attic of my Gardenia and it has a hip roof which means the roof trusses are all different configurations and come down very low to the eaves. There is ductwork, pipework, and wires running everywhere; cathedral & tray ceilings; very tough access and in general it looks near impossible to do any kind of a decent job. For myself, I wouldn't invest my money there. Possibly, in a straight gable roofed ranch with no ductwork in the attic a good job could be done but does anyone have that?
