Xtreme-MET Radiant Barrier (1000 Square Feet Roll) Xtr-1000-b

Q: What is the difference between the ultima-foil and the xtreme radiant barrier foil

The Ultima-foil radiant barrier is an aluminum product that blocks 97% of the radiant heat. When crumpled, it behaves like foil in that it retains the shape it is formed into. Xtreme radiant barrier is a metalized poly that blocks 95% of the radiant heat and it is very difficult to crumple and shape as it tends to open back up and remain flat. Both versions are virtually tear-proof.

Q: does it help in the winter months with lesser heating bills? we live in Meadvill PA and have very cold winters. There is a company trying to tell us it will help keep our heating bills down while keeping the house warmer.

A radiant barrier will absolutely not lower your heating bills if it is placed on the underside of the roof. Any heat radiated up from your house would be lost once it gets above the attic insulation. Heat is what moves and radiates, not cold. A radiant barrier works only when the sun is radiating heat onto your roof. Any one that tries to tell you a radiant barrier can lower your heating bills by XX dollars is either lying or does not understand heat transfer and building science. With that said, a radiant barrier will work well to keep your attic cooler in the summer, during the day, if your roof is exposed to a lot of sun. A thorough air sealing job, well-sealed ductwork, and proper attic insulation will help you be more comfortable and save money in summer and winter, night and day.

Q: For attic installations of Xtreme, which is advertised as breathable, is it necessary to leave an opening along the entire peak for air to escape?

If you have a ridge vent, then yes, you need to leave an opening of 6 inches on either side of the ridge vent at the peak. If you have any other roof vents (turbines) then you need to cut out an opening below the vents to ensure adequate ventilation. The key when installing a radiant barrier to the underside of the roof rafters is to make sure you don't obstruct any existing inlet and outlet ventilation in order for full attic space ventilation.

Q: Can I wrap this around the fiberglass only covered hvac return ducts in my attic that have no radiant barrier? Is it worthwhile?

I guess it would help and you would have to tape the joints. A lot of work?????? and not sure how much return you would benefit.
