What is Type 2 construction?
Type 2 construction is typically found in new buildings and remodels of commercial structures. The walls and roofs are constructed of non-combustible materials. Specifically, walls are usually reinforced masonry or tilt slab, while roofs have metal structural members and decking.

What is the FRL requirement of that separating wall?

What is the required fire rating of a wall and door that separates two buildings?
Such openings shall be separated vertically not less than 3 feet (914 mm) by spandrel girders, exterior walls or other similar assemblies that have a fire-resistance rating of not less than 1 hour, rated for exposure to fire from both sides, or by flame barriers that extend horizontally not less than 30 inches (762 mm) …
How do you make a 2 hour fire rated wall?
Double the number of Type X sheets on the wall for a simple system installed over fire-resistant fiberglass insulation; each sheet of 5/8-inch Type X drywall is rated to resist fire for one hour, so two layers will produce a two-hour firewall. Put two sheets together on one side or use one sheet on each side of a wall.

A firewall is a special type of fire separation assembly commonly constructed of non-combustible materials that subdivides a building or separates adjoining buildings. A firewall is the ultimate defense against the spread of fire.
What is 30 minute fire separation?
The new floor, and any structure supporting it, must have a fire resistance of 30 minutes from underneath. This should extend to the inside face of the external walls. The fire resistance of a floor is dependent on the ceiling beneath, the size and spacing of joists, and the boards over it.
