ISO-BLOCO XTHERM is a omni-functional sealing tape with microtherm technology. It was specially developed for thermal insulation that is indirectly exposed to weathering. It is especially suitable for fitting components with larger frame installation depths and commonly available front doors and lift-and-slide doors. It offers excellent thermal insulation properties (Microtherm effect) over the entire installation depth. As it adapts very well to the installation joint, ISO-BLOCO XTHERM also provides excellent sound-proofing.
