Door sealing cords are an important element ensuring the safety and efficiency of fireplaces and stoves. Their proper functioning is essential to maintain optimal combustion temperature, minimize fuel consumption, and prevent smoke and toxic gases from escaping into the room.
The main task of door sealing cords is to ensure that doors are hermetically sealed. The cords create flexible thermal insulation for the fireplace between the metal door frame and the body of the heating appliance. This ensures that the air for combustion is supplied in a controlled manner and not through leaks. This prevents inefficient combustion, smoke and fumes from escaping, and sparks and embers from escaping from the firebox. Cords for sealing doors, which also provide insulation for bread ovens, are usually made of materials with high resistance to extreme temperatures, reaching up to 1000°C and above. These can be durable glass, ceramic or aramid fibers.
Operation, construction, and installation methods for components such as door sealing cords.
During operations such as installing a fireplace insert, not only high-temperature insulation mats are necessary, but also door sealing cords, which are also useful for filling the gap that forms when one fireplace insulation board is installed next to another. These can be found in the Vitcas store. Proper installation of the cord, although simple, requires precision. After preparing the surface, apply heat-resistant adhesive and insert the new cord into the gap. Leave the door open for the time specified by the adhesive manufacturer to allow the adhesive to dry and set completely.
Regular inspection and replacement of worn door sealing cords requires little effort. However, it is of great importance for the safety, efficiency, and economy of use of any fireplace or stove.
