INSTALLATION AND DOCUMENTATION
Used at the ridge for roofs with a pitch up to 120 % (50°). For pitches between 70 % and 120 %, it is necessary to cut the flat part above the corrugations.
A gap of 1 cm is necessary between both APRON PIECES, in order to ensure appropriate ventilation.
When used as a wall abutment, the ventilation gap between the wall and the APRON PIECE is also necessary. Watertightness is secured by using an aluminium Z-profile and a line of silicone mastic.
For specific roof details, please refer to ONDUVILLA fixing guide.
