Bitumen aluminum tape Copper 250 mm x 10 m – self-adhesive sealing and repair tape, weather-resistant

Bitumen Aluminum Tape 250 mm, Copper –permanently waterproof sealing & repairs

With this Copper-colored bitumen tape, you can seal joints, transitions and damaged areas outdoors quickly and reliably. Whether on roofs, gutters, sheet metal, steel structures or glass roofs/greenhouses: the tape is self-adhesive, bonds strongly and is ideal as a sealing and repair tape.

Why this aluminum tape?

• Waterproof sealing – perfect for joints, cracks and connections

• Self-adhesive – quick application without special tools

• Strong adhesion thanks to elastomer bitumen coating on an aluminum/PE composite

• UV & weather-resistant thanks to the aluminum surface

• Water impermeability tested (DIN EN 1928)

Typical applications

• Sealing joints and cracks in gutters, sheet metal, roofing/roof coverings

• Permanently waterproof sealing for glass roofs & greenhouses

• Eaves and valley flashings, sheet overlaps & steel structures

• Sealing corrugated fiber cement roof panels

• Timber frame construction: transitions between wall and base slab (plinth area), sill/basement or base slab

• Waterproof sealing under window sills

• Sealing wood fiber underlay roof and wall panels in house construction

• Sealing wall caps in landscaping

• Waterproof bonding/sealing of roof windows, chimneys & pipe penetrations

• Connections between roof and wall

Application – how to get a proper watertight seal

• Prepare the substrate: dry, clean, dust- & grease-free, abrasion-resistant and load-bearing.

• Porous/monolithic substrates (stone, rough concrete, plaster): use a universal primer.

• On old wooden sheathing, roof tiles and old bitumen waterproofing, use our Bitumen Primer V

• Observe a minimum temperature of 10 °C for both the tape and the substrate. 

• To improve adhesion, warm the substrate and the tape to 20 °C

• Positioning: align the tape, remove the release film.

• Apply & press down: press firmly (avoid voids/bubbles), ideally using a pressure roller.

• Note: Each tape comes with application instructions.

Tip for a professional result

Substrates should be dry, clean and sound. On rough concrete and stone, universal primer ensures maximum adhesion and a permanently secure seal.
On old, weathered bitumen roof waterproofing, shingles and roof tiles, use our bitumen primer
