EUROTOP N-35 membrane - Roof Windows

• At the eaves, EUROTOP N35 should be sealed with adhesive tape (e.g. butyl) (fig. 4), so that the bottom edge lies over the gutter (fig. 5) or lies on afelt support tray.• To protect vertical walls against moisture ingress at the verges, underlay should at least cover the wall, and it is best if it is extended to the external wallface (fig. 6).fig.5fig.6• On boarded roofs, EUROTOP N35 is best installed using the horizontal overlapping method.• With extractors, soil pipes, and aerials etc., pierce the membrane (fig. 8). You must cut out a star shape in the EUROTOP N35, and then turn it up, glueand seal around the protrusion with adhesive tape, and above the hole you place a covering gutter.At an abutment the membrane should be turned up at least 75mm or be taken behind lead flashing and should be sealed as in fig.10.fig.8 fig.9 fig.10• Around chimneys (fig. 11), roof windows, etc., you should seal the EUROTOP N35 with adhesive tape, so that the upturned parts of the membranecreate a seal of 5-15 cm in height. In the valley you must seal all cracks, splits and overlaps and you should also seal around the corners with adhesivetape (fig. 12).• Around roof windows we advise you to install a FAKRO XDP underfelt collar (with attached additional insulation material) (fig. 13).fig. 11 fig. 12 fig.13• On roof hips (and ridges) you should lay EUROTOP N35 with the overlaps protruding beyond the angle rafter. Similarly, at the hip there should be twolayers of EUROTOP N35.• When laying EUROTOP N35 in a valley detail a continuous single strip (runner) must be placed along the entire length of the valley and fixed at the topand bottom; following this, horizontal lengths should be laid on top of the valley runner and lapped in a staggered manner• Above skylights, chimneys, roof windows, and roof hatches etc. you should make small gutters of EUROTOP N35 (fig. 8). These gutters protect againstthawing drips, or wind driven rainfall leakage.• For bonding EUROTOP N35 during installation you should use adhesive tape, designed specifically for this purpose.Further Information
