That depends compleatly on what type and what brand of insulation you want.
Batt insulation comes in a variety of widths, lengths and thicknesses.
batt
A batt is one of a series of fibres used for stuffing, especially for insulation.
A batt is a form of insulation; instead of being a roll (as most insultion comes), a batt is usually a rectangular piece of insulation. A batt usually has a high R value and it is a lot thicker than most insulation so it is impractical to try to have it in rolls as they would be too large to handle easily.

Can lights that are rated as IC "insulation contact" are the only style approved for use with blown or batt insulation.

depends on the batt.. some will cost you 30 - 100 dollars depending on the batt.
Usually the wrap iss installed first. Rigid foam insulation is often installed outside the building wrap, and batt insulation is always installed inside the building wrap. This is because batt insulation is much more moisture absorbent than most rigid foam so needs to be protected from external moisture. So batt insulation will not be installed until after the building wrap is in place to protect it, and externally installed rigid foams are not fixed in place until after the wrap is in place because they are fixed over it.
The R-value of standard Batt insulation typically ranges from R-3.1 to R-3.7 per inch of thickness. However, the actual R-value can vary based on the specific materials and thickness of the insulation.
