ISO-BLOCO HYBRATEC is a multi-functional tape 4.0 that is equipped with hybrid technology. The new hybrid technology combines the high resistance of film technology to air and driving rain with the reliable flexibility and movement absorption ability of high-quality multi-functional tapes tested and certified to MF 1 (previously BG 1 and BG R). With an a-value of 0.00 m³/[h·m·(daPa)2/3], the pre-compressed tape is 100 % air tight when used on the interior and thus prevents convection heat losses. By integrating several barrier layers, ISO-BLOCO HYBRATEC complies with the principle “inside tighter than outside”.
