Above is a diagram of the sealing of the PR05 cast iron oven door.
The airtight door is fitted with sealing cords between the glass and the casting, and between the casting and the door frame, and therefore has a higher capacity to prevent carbon monoxide from entering the room.
As a result, it offers increased safety when installed in a cooker or fireplace oven.
In addition, ovens equipped with airtight doors are more efficient. Less fuel is required to produce the same amount of heat as a cooker with a leaky door.
