Bitumen aluminium tape – self-adhesive, in 7 colours and 8 widths
Bitumen aluminium tape is the most-purchased product in the entire shop – because it can be used for so many tasks around the home. Joints in guttering, cracks in roofing felt, connections at walls and window sills, sheet metal joints, glass roofs, pipe penetrations: the self-adhesive aluminium sealing tape seals quickly, permanently and without tools. The two most important decisions: the right width and the matching colour.
50 mm – the entry width
For narrow joints, cracks in roofing felt, gutter seams and tight connections. Most economical entry point, tiered pricing from EUR 0.69/m (>35 rolls). EUR 7.20 / 10 m.
To the 50 mm tape → Connections & transitions ★100 mm – the bestseller
The most popular standard width – for roof-to-wall connections, transitions, window sills and wide seams. EUR 10.80 / 10 m (EUR 1.08/m), silver and black.
To the 100 mm tape → Large-area sealing500 mm – the wide tape
For membrane-to-wall connections, chimney connections and large-area coverage where the 100 mm tape is not wide enough. EUR 49.90 / 10 m (EUR 4.99/m).

Choosing the right colour
7 colours – for visually coordinated sealing
Neutral and universal
Silver (aluminium) and black are the most popular colours. Silver suits metal construction and sheet metal roofs. Black harmonises with black roofing felt and dark structures.
Classic & distinguished
Copper for copper gutters, copper roofs and historic buildings. Lead grey for roof dormers, chimneys and connections where a classically understated tone is desired.
For coloured roofs & façades
Brown for timber construction and brown roof tiles. Terracotta/brick red for red roof tiles and clinker. Red for red sheet metal roofs and red façade elements.
Applicable everywhere – the most important uses
Roof, guttering, sheet metal, window sill and more
Bitumen aluminium tape can be used on almost all smooth exterior surfaces: bitumen roofing felt, metal, steel, aluminium, copper, concrete, glass roofs, greenhouses, timber and wood-based panels. Whether rain gets through a crack over winter, a gutter seam leaks, a chimney connection is no longer watertight or water penetrates under a window sill – bitumen aluminium tape is fitted in minutes and immediately watertight.
Frequently asked questions
Frequently asked questions about bitumen aluminium tape
Which substrates does bitumen aluminium tape bond to?
Bitumen roofing felt, metal, steel, aluminium, copper, concrete, plaster, timber, timber-based panels, glass and GRP. The substrate should be clean, dry and grease-free. On very rough substrates, improve adhesion by pressing firmly or apply bitumen primer.
Which width do I need for my chimney connection?
This depends on the connection geometry. For chimney-to-roofing felt connections, 150–300 mm is typical – the tape must have at least 5 cm of contact on both sides. For wide chimney cross-sections, 300 mm or 500 mm tape is recommended.
Can I stick bitumen aluminium tape to a damp substrate?
For emergency sealing in damp conditions this is possible to a limited extent – adhesion on damp substrates is reduced. For a permanent bond the substrate must be dried. In wet emergency sealing, press the tape firmly and allow to dry before water stands on it.
Are there tiered prices?
Yes. For 50 mm tape: from 6 rolls EUR 7.10, from 18 rolls EUR 7.00, from 35 rolls EUR 6.90 per roll. For 75 mm tape: from 4 rolls EUR 8.80, up to from 21 rolls EUR 8.50. For larger quantities the tiered pricing is worthwhile.
What is the difference between bitumen aluminium tape and normal adhesive tape?
Bitumen aluminium tape has a bitumen adhesive layer (not acrylic or rubber adhesive) and an aluminium surface. Bitumen is permanently weather-resistant, UV-stable and watertight – normal tape degrades quickly under weathering. Always use bitumen aluminium tape for outdoor applications and permanent sealing.
Can the tape be painted over or plastered?
Paintable with a suitable primer. Plastering is more difficult – the tape is elastic and plaster is not, so cracking in the plaster at this point is possible.
