  • Easy and secure fixing
    The fastening of studded and drainage sheets to the perimeter insulation takes place without any perforation of the sealing. This means less material waste, no temporary aid structures required for the temporary fastening of the sheets.


Prerequisite: The perimeter insulation panels must be firmly glued to the subsurface and/or the sealing and stand on a stable subsurface at the base.
The fastening is carried out at the upper edge of the perimeter insulation at a distance of approximately 50 to 70 cm or from top to bottom on the entire insulated area with approximately 1 screw/sqm.
For this purpose, the DELTA®-BEFESTIGUNGSSCHRAUBE (Fastening screw) is pierced through the drainage membrane and then screwed into the insulation board. At breakthroughs such as for example light shafts, the screws are set as at the edges at a distance of approximately 50 - 70 cm.
