Certificate type
An air and water tight membrane with variable vapour permeability for connection between the external perimeter of the window, door or curtain wall frame and the backing wall substrates.
Applied to principally to the external perimeter of windows doors and curtain walling or over other linear construction joints. Often accompanied by illbruck ME508 Duo EW/F applied to the internal perimeter for a complete perimeter seal . ME501 Duo HD may also be used internally for difficult details, or where the width of the membrane exceeds the available sizes of Me508 Duo EW/F. Please consult illbruck for advice.
ME501 Duo HD is a highly water tight and airtight "intelligent" membrane with reactive and variable vapour control. ME501 Duo HD provides a high performance seal to the external perimeter joints between the window, door curtain wall and the external construction reveal. The membrane is suitable for external and interior use and provides an air and weathertight but breathable seal. The standard version is bonded on both edges with illbruck SP525 Polymer Hybrid adhesive sealant or another sealant specified by illbruck for difficult substrates.
