Micore 300 can be cut using a sharp utility knife, similar to cutting a piece of drywall.

Should 2 sheets side by side be joined for a continuous fire retardant shield, and if yes with what material?
This board is not meant to be used as a heat shield, but you may consider something such as a stove board.

Fast delivery, product in great shape!

Used to make a fire shield for my new wood stove. Put on a tin tile facing--and it's beautiful!

Just what I needed for floor protection project

I needed a non-combustible board with a minimum insulation rating to build in floor protection system for a wood burning kitchen range. This board will be the bottom layer of the protection system followed by cement backer board and then ceramic tile. The top of the ceramic tile will be level with the surrounding kitchen floor for a better look and avoidance on any tripping hazards. If you are interested I can provide heat transfer calculations and construction photos.

Pros

Nice size for handling, just the right thickness to provide required R-value, easy to work with.

Cons

A little more expensive than my original calculations, but then everything construction related has increased in price.
