Product description
The OTTOTAPE Trio-BKA MF1 is based on an impregnated, compressed PU foam with variable sd-value technology. It offers excellent temperature resistance, is UV- and weather-resistant and meets the requirements of modern sealing systems. Thanks to its three-stage functional structure it simultaneously provides the inner airtight seal, the central thermal insulation and the outer driving-rain tightness.
Typical areas of use are construction, installation, window construction, facade technology and demanding refurbishment projects. For optimum application the tape should be chosen to match the joint width and inserted without tension.
