Illbruck ME500 Duo Flexible Window Membrane

ME500 is a polyethylene co-polymer film with non-woven fleece fabric. It is an intelligent membrane providing perimeter window seal for airtight internal & weather tight external joints.

Usage/Purpose

ME500 Duo Flexible Window Membranes (E & W) comprises a tear-proof woven fleece fabric with a polyethylene co-polymer film. An integrated movement pleat is included in the foil which complies with the planning and installation recommendations of DIN 4108-7 and with the RAL Quality Assurance Association for windows and doors. It is attached to the wall with butyl adhesive, and to the window /door with a self-adhesive strip. The product has a specially designed reactive foil – water vapour permeability (sd value) changes depending on the humidity inside the joint. This allows the product to perform as an intelligent seal for airtight internal joints, and weather tight breathable external joints. The intelligent reactive system ensures that the joint always dries at the maximum rate. In non-fenestration applications, the membrane can be used to seal across adjacent insulated panels as an airtight or weather tight seal

Benefits

The variable sd value ensures that the joint dries out quickly, thus protecting against mould and moisture damage
Single product acts as internal airtight seal and external weather tight but breathable seal
