Description
The Birtel ceramic fibre tape is a high-temperature sealing tape based on ceramic fibre, self-adhesive on one side, for seals and heat shields on ovens, chimneys and in fire protection. It is classified as A2-s1-d0 to EN 13501-1:2007 and therefore corresponds to building material class A2 to DIN 4102-1. The 10 m roll is available in four width and thickness combinations, from 9 x 2 mm to 15 x 4 mm, for stove builders, heating engineers and ambitious self-builders.
Advantages at a glance
- Temperature reserve: The fibre remains stable continuously up to 900 °C, withstands 1200 °C short-term and only melts above 1330 °C.
- Insulates, not just seals: Thermal conductivity is 0.07 W/mK at 200 °C and rises to only 0.22 W/mK even at 800 °C.
- Virtually no smoke-gas development in a fire, because the organic content is minimal.
- Asbestos-free and biosoluble: The fibres are not regarded as carcinogenic, so no hazardous-substance labelling applies.
- Self-adhesive during installation: The acrylate layer holds the tape in place while positioning, until the construction clamps it.
Applications
- Sealing of oven doors, oven flaps and chimney doors
- Sealing of cleaning covers and stove pipe connections
- Backfill material and backing strip in fire protection
- Sealing of ventilation and air-conditioning ducts
- Heat shielding on hot components and partition wall connections
Limits & notes
The temperature rating applies to the ceramic fibre, not to the adhesive layer. The acrylate adhesive is an installation aid and loses its function when hot; the construction must ensure the sealing effect by clamping. The manufacturer does not state approval for permanent weathering exposure; the tape is intended for dry installation situations. For moving joints, a flexible high-temperature sealant is the right choice.
Processing & tips
Prepare the sealing surface so that it is clean, dry and free of grease and dust, and remove any old seal residue completely. Cut the required length cleanly with scissors or a craft knife rather than tearing it, so that the cut edge does not fray and less fibre dust is produced. Peel off the protective film, lay the tape on without tension and press it down from the centre towards the ends; do not stretch it, or it becomes thinner at the ends. Butt joints rather than overlapping them, so that the sealing surface stays flat. Store dry at room temperature.

Frequently asked questions
Does the adhesive withstand 900 °C?
No. The acrylate layer is an installation aid for positioning; the temperature rating applies to the ceramic fibre. Once installed, the construction holds the tape in place by clamping.
Is the tape labelled as a hazardous substance?
No. The fibres are biosoluble and not regarded as carcinogenic, so no CLP labelling applies.
What width and thickness do I need?
Measure the sealing surface: the tape should cover it completely without protruding over the rebate. Four width and thickness combinations are available: 9 to 15 mm wide, 2 to 4 mm thick.
How do I cut the tape to length?
Cut cleanly with scissors or a craft knife rather than tearing. This stops the edge fraying and produces less fibre dust.
