Joint sealing tape 20/2-4 mm, 12.5m, grey

The joint sealing tape 20/2-4 mm, 12.5m, grey, according to DIN 18542 BG1, is a joint sealing tape made of impregnated foam. It serves as primary sealing for joints and connections exposed directly to weather. In addition to sealing against wind, dust, and splashing water, it also provides sound and thermal insulation. This immediately reduces energy costs and preserves the value of the building structure.

Areas of application:

• Window construction, interior finishing
• Facade construction (also natural stone)
• ETICS, timber frame construction, wood and metal construction
• Prefabricated construction, container construction, noise barrier construction, roof construction (e.g., windproof connection of foils) and much more.

Delivery form:
