Sealing mat with vermiculite backing, 16 x 17 cm

Heat-resistant sealing mat with vermiculite coating – cuttable & flexible (16.3 x 17.5 cm)

This high-quality sealing mat is ideal for use in fireplace and stove installations. With its vermiculite-coated back side (formerly fine sheet metal), it offers a durable, abrasion-resistant, and temperature-resistant solution for sealing flue pipe cleaning openings, chimney doors, and combustion plates.

The combination of glass needle fleece and heat-resistant coating reliably protects against flue gases and condensates. Thanks to its flexibility, the stove gasket can be effortlessly cut to size with scissors or a knife and adapts optimally to various contours – remaining sealed even after repeated opening.

The coated side must be installed facing the flue gas side to ensure maximum durability.
