EPDM Membrane

Air- and watertight EPDM based membrane used for the weatherproofing of external façades, typically between the window frame and building envelope. Also suited for use as water barrier in the foundation wall. 1,2mm extra thick membrane. Conforms to CE: EN 13984.

Instruction

• Depending on the situation, the installation of EPDM Membrane can be carried out before or after the installation of the façade elemement (eg window frame). Cut EPDM Membrane 10 cm to 20 cm longer than the length of the relevant facade element (eg window frame). This acquires 5 cm to 10 cm extra on both sides to overlap the corners. The foil can be attached to the facade element with Soudaseal EPDM or by means of a mechanical fastening (pressure clamp strip, terminal strip, etc.). Start at the bottom of the facade element and work upwards for a good drainage. After installing the facade element, fill up the connection joint between window frame and structure with a suitable PU foam (eg Flexifoam). After full curing of the PU-foam (and possibly cutting it off) EPDM Membrane is bonded to the structure with Soudaseal EPDM. To do so, apply a 5 to 6 mm thick and uninterrupted (= airtight!) adhesive bead. Calculate +/- 1 adhesive bead per 5 cm EPDM width. Apply the foil, not too tight, on the structure to absorb any movements between the various building elements but avoid folds. Then press the foil evenly, with a pressure roller, so that a 1 to 2 mm thick adhesive layer of approx. 25 mm wide is obtained. That way there is sufficient bonding surface and the adhesive can cure well. The overlapping parts of the EPDM Membrane (eg in the corners) must be bonded with Soudaseal EPDM. The bonding can only be loaded after full curing of the adhesive. Consult the technical data sheet of the adhesive for this.

Applications

• For air- and watertight sealing of connections, foundations (against rising dampness) and window and door connections: outside inner leaf (prior to application of the facade insulation), outside massive walls, outside ventilated facades and under the window (or door) sill.
