What Is a Pet Door Wall Liner?
A pet door wall liner is a sleeve or tunnel that lines the opening created in your wall—typically between the interior and exterior surfaces—when installing a pet door through a brick or double brick wall.
But why does a wall liner for a pet door matter?
-
Without a wall liner, the cut-out hole would expose brick, mortar, insulation, or wall cavity, which looks messy and can be unsafe.
-
A wall liner creates a sealed, smooth, and durable tunnel that connects both sides of the wall and allows the pet door flap to function properly.
-
It improves aesthetics, insulation, and weatherproofing while making the installation look clean and professional.
