When the wall you cover has a window, you have to install the Beonstone window sill before continuing your installation with the last row below the window.
Beonstone window sills are designed for easy installation and provide the watertight protection required by exterior walls. Their unique shape features a 3° slope to drain water away from the wall. 813 mm x 88.9 mm x 51 mm (32 po x 3.5 po x 2 po)
To complete this section, custom cut a stone panel to produce the shape you need. Leave a 3 mm (1/8 in) space between the window and the sill cap.
For a piece that would be completely cut horizontally and therefore would no longer have the anchor strip, you should proceed in the same way as the last row of a wall. (See section 3 : installation)
Continue the installation of your wall around the window.
