How to install HeatblockULTRA Radiant Barrier Spray

[1900sextasy]

do you have a working number?

somebodies lying. the foil people say foil only works with an air gap of 1.5 inches so heat will not transfer or conduct. then this stuff really allows whole roof to conduct shingle heat by making the wood sheathing to conduct all its heat into the attic.

explain this huge discepancy. it is nonsense.

looks like the same product used on a lot of school roofing @_@

It will work to a certain % and you gotta respect the guy in the attic for his hard work. Whats noticeable is the blown insulation... much more comfortable to be in an attic with 'CertainTeed white'.

GARBAGE - THIS CRAP IS A JOKE AND DOES NOT WORK. DON'T WASTE YOUR MONEY!

What kind of sprayer is this applied with? Is it a regular paint sprayer? What kind / size of tip on the end of it?
