What is the self-adhesive bitumen tape BILKA used for?
The BILKA bitumen tape is a flexible self-adhesive waterproofing product used for sealing and moisture protection in suitable roofing details. The official page presents it as an auxiliary accessory, not as a primary roofing covering. It can seal local joints when the width and base are properly selected. The specific application must follow the technical instructions for the tape and the construction detail, without replacing necessary claddings or membranes.
What sizes does the BILKA bitumen tape come in at LATIVA?
Shopify offers four widths at a length of 10 m: 7.5, 10, 15, and 30 cm. In the options, the length is written as "10 ml," but BILKA’s official documentation specifies it as 10 m. This is important when calculating rolls. The narrower tape is for small local joints, while the wider one covers a larger area; the final choice depends on the required contact surface and intended overlap.
In what colors and SKUs is the BILKA bitumen tape available?
The product has 12 Shopify variants: four widths, each in gray, RAL 8004, and RAL 8017. For example, 7.5 cm x 10 m / Gray is SKU LT-5055, and 30 cm x 10 m / RAL 8017 is LT-5044. The color is chosen based on the visibility of the detail but does not change the required width. Both characteristics must be included in the order because the same color has four different size codes.
How do I choose a width of 7.5, 10, 15, or 30 cm for the BILKA bitumen tape?
The width is chosen according to the actual sealing area, equal contact fields on both sides, and the necessary overlap. A 7.5 cm tape is not automatically suitable for a detail that requires 15 or 30 cm coverage. Before purchase, measure the joint, bends, and obstacles, and for a complex chimney or wall, follow the project cladding. BILKA does not publish a universal width for every node, so a photo and measurements are needed for an accurate choice.
What base is needed for adhering the BILKA bitumen tape?
The tape is self-adhesive, but the official product pages do not publish a complete list of acceptable bases, minimum temperature, or primer requirements. Therefore, the surface and conditions must be checked according to the label or technical sheet of the specific roll. It is not automatically accepted that a dusty, wet, greasy, or unstable base will provide reliable adhesion. In case of doubt, LATIVA must confirm the preparation and compatibility before installation.
Can the BILKA bitumen tape replace sheet metal cladding around a chimney?
The bitumen tape should not automatically replace the designed set of claddings around a chimney. BILKA defines it as a flexible waterproofing auxiliary tape, while the chimney node has separate profiles and requires water control on all sides. The tape can be part of a suitable detail, but the choice depends on the covering, slope, base, and thermal movement. For a whole chimney, dimensions and a confirmed scheme are needed, not just the total roll length.
