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.
Application
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.
Description
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.
Features and benefits:
- Complies with principle of ‘inside tighter than outside’ in order to facilitate efficient vapour control - avoids interstitial condensation.
- Excellent drying potential.
- High strength, tear resistant.
- UV stable; will tolerate up to 12 months direct exposure prior to covering.
- Membrane can be applied before or after window installation to suit on-site details and programming.
- Also available in a self-adhesive option (ME501 VV) and with gasket options for fixing to the profile.
