Compriband with 3-level properties

EGOPREN C3 is a pre-compressed, single-sided self-adhesive sealing tape made of soft polyurethane foam and supplied in roll form. It features a special protective impregnation. EGOPREN C3 replaces three sealing products in a single solution. It is designed for driving-rain-resistant and airtight sealing of window and door joint gaps while simultaneously providing thermal and acoustic insulation throughout the entire construction depth. Once installed in the joint, the sealing tape gradually expands depending on temperature and time, allowing it to adapt to varying joint widths and irregularities in the adjoining building components. Its performance is ensured by the tape’s special construction, which combines moisture-variable vapour Diffusion properties with a continuously airtight contact surface.

EGOPREN C3 has been specifically developed according to the principle of “more airtight on the inside than on the outside.” Thanks to its multilayer construction consisting of impregnated foam and a moisture-variable membrane, it provides reliable, simple, and fast sealing for the installation of windows and doors. EGOPREN C3 can be used with window frames featuring coupling mullions. At least one adhesive surface must be present on two mullions, both on the interior and exterior sides. The use of groove cover profiles is recommended. Uneven expansion may occur when the tape is doubled. The product is not paintable or plasterable and is not intended for use in façade movement joints. The sealing tape is UV- and weather-resistant within its intended application range. When installed at maximum joint expansion, permanent covering is required within 4 weeks. For joints between solid building components, we recommend using EGOPREN C1, classified according to BG1.
