Is this door approved for Florida hurricane codes?

No. The listing states it is not tested for Florida, so it does not carry Florida product approval. Coastal Florida jurisdictions that require wind-borne debris approval will not accept it.

What size opening does a 37.5 x 98 inch unit fit?

The unit is 37.5 inches wide by 98 inches tall, slightly larger than the nominal 36 x 96 door. Plan the rough opening with the frame and shim space your installer specifies.

Is the glass insulated?

Yes. It is double-glazed insulated glass at 5/8 inch thick, which helps with heat and sound compared with a single pane.

Does it come prehung with a frame?

The listing gives only the unit size and slab thickness, so confirm with the seller whether it ships prehung in a frame or as a slab only before ordering.

How does this door compare with a full-lite steel door?

A full-lite door is glass top to bottom, so it lets in more light but leaves less steel and more glass to defend. This 2/3 lite keeps a solid lower panel behind the grille, which suits entries where privacy and security matter more than maximum daylight.
