Self-adhesive butyl rubber assembly and sealing tape with permanently anchored aluminium lamination

Excellent resistance to UV, weathering and water

  • The butyl tape can also be used outdoors and withstands rain and any other weather influences (not suitable for use under water).

  • Non-corrosive

High adhesion to absorbent and non-absorbent surfaces

Can be used on all the surfaces in the construction sector, e.g. steel, aluminium, glass, plastic, wood, concrete, masonry, bitumen etc.

Butyl tapes are self-fusing

The tape is fully functional immediately after application and complies with all required properties.

Impermeable to vapour diffusion

The butyl tape enables water-tight sealing and prevents moisture from penetrating the building.

  • No bimetal effect

  • Compatible with bitumen

  • Noise-reducing

  • Simple to apply

  • Odourless

  • Solvent-free and bitumen-free
  • Screwing in/penetrating the butyl tape must be avoided

  • Butyl cannot be secured mechanically!
  • Complies with IVD technical data sheets no. 5, 19-1, 19-2, 25, 29, 31, 35

  • Compatibility with bitumen according to DIN EN 1548

Complies with VOC requirements according to:

  • EMICODE EC 1 Plus

  • AgBB scheme

  • French VOC Class A+ and "KMR ordinance"

The usage instructions are recommendations based on the tests we have conducted and on our experience; carry out your own tests before each application.

Application area

For covering seals of construction and connection joints in areas of industry and construction, concrete and concrete finished parts construction. Typical applications include sealing dome lights, window frames, slanted-roof glass structures (with press-on profile only), greenhouses, conservatories and other butt joints made from glass, plastic and metal. And sealing roof passages, rain gutter connections or connections between projecting roof and masonry.


The surfaces to be sealed must be dry, capable of bearing load and free from grease and dust. The application temperature should not be below +10°C. Absorbent and porous surfaces must be pre-treated with Würth butyl/bitumen primer (art. no. 0892875).

To obtain good initial adhesion to the surface, the tape should be pressed onto the surface and smoothed using a press-on roller (art. no. 0693011756). Folds and creases should be avoided.

Butyl has a "cold flow" tendency (flow characteristic of the tape). Therefore, the tape should always be fitted with a press-on profile to prevent the seal from slipping as a result of, for example, the weight of snow or backed-up water. However, using excessive contact pressure on the profile will cause the sealing compound to be "pushed out". Also, never compress the butyl tape to the zero point (use the supplied disc as a spacer)!

The adhesive surface of the sealing tape must be at least 1/3 (per contact surface) of the tape width when gluing over joints. Overhead adhesion tasks are not permitted without additional mechanical fixings. When sealing glass retainer profiles, the rubber profile must not lie on the sealing tape. The width of the butyl tape must be selected such that the tape is located between the rubber profiles.

Packaging unit

The packaging unit defines the number of articles in one packaging. In the catalog segment you can choose from different packaging units if a pop-up menu is displayed.

Just leave the field empty if you don't know the packaging unit when directly entering the article number in the shopping basket or when importing with Easy-/VarioScan. The packaging unit will be determined automatically.

Structure of our article number

The article number is made up of the following: VVVVAAABBB
VVVV = 4 digits for prefix number (please note that the first digit is currently always 0)
AAA = 3 digits for dimension part 1
BBB = 3 digits for dimension part 2

Example article number structures:
Example 1: Screw with dimensions of 4x10 mm:
00574 10 (2 spaces between the 4 and the 10)

Example 2: Screw with dimensions of 10x20 mm:
005710 20 (1 space between the 10 and the 20)

Example 3: Flat washer with an internal diameter of 6 mm:
