I am in the process of considering a HVAC replacement but am wondering about foam and radiant barrier.
What is the experience is in the real world with paint on radiant barrier under the roof deck? Worth the $ ? (North Tx, 1400 sf frame house)
Have always thought foam would be great but I understand it's very expensive. If you did radiant, will foam stick and would that be a waste of money? In other words, wouldn't just foam be good enough?
Just wondering how the ROI works out if I just foamed the crap out of the roof, radiant or not vs replacing the old still working HVAC. Any comments on how well radiant barrier paint and foaming the roof deck have worked out are appreciated. Yes HVAC needs replaced but limited budget and the tax credit will work either way. So if I don't have the bucks to do it all, do I replace the HVAC with something efficient or Foam/barrier the roof ?
Yeah I know it's a HVAC site but you guys seem to tell it like it is & I know someone out there is doing both for a living.
