Polystyrene baffles have several disadvantages: becoming slim and flexible, they're able to’t resist the pressures from dense-packed cellulose or blown-in fiberglass; they don’t ventilate the complete width in the rafter bay; and as generally installed, they permit air to leak out the highest of the insulated assembly.

Unfortunately that appears like It truly is far too quick.

Most business roof assemblies Will not hassle with the fluffy stuff. They simply fulfill a hundred% from the R-worth needs for the roof with rigid foam (possibly EPS or polyiso) and skip the batts totally. That's just how I recommend that you commence.
