Determining whether you will need an insulating liner depends on where you plan to place your built in grill. AOG Built In Grills are not insulated and require a minimum of 18” clearance from unprotected combustible materials on all sides. Combustible materials such as wood, plastic, or stucco with wood framing require the purchase of the insulating liner to protect your grill and island.
If your island is made of non-combustible materials such as stone, brick or steel you are not required to purchase the insulating Liner.
