Our Vermiculite Calculator helps you determine the amount of vermiculite needed to insulate your chimney liner effectively. By insulating with vermiculite, you can enhance the longevity and efficiency of your flexible flue liner while minimizing heat loss through the chimney. It is particularly recommended for brick chimneys located on external walls, and the best practice is to fill around your chimney liner from the top, ensuring coverage above the register plate for optimal installation.
