Insert the cut edge into the corner accessory, align the bottom edge with theSuitable datum and use a single fastener at a corner to temporarily holdmembrane (section 1.4.7) Refer the panel.fastening 4.Adjust the panel so that the grooves are vertically level beforeStainless steel fixing off temporarily with a fastener at the opposite corner.fastenings5.Weathergroove has a unique rebated edge that forms a regular groove when installed with an appropriate control gap. When joining panels, leave a 2mm gap in between panels to maintain theSuitable sealantstandard spacing of the grooves. Before installing the next panel, run a 5mm bead of suitable, flexible sealant along the length of the Alcor flashing to seal both edges of the Weathergroove panel. NOTE: Natural products are composed of unsealed natural hardwood timber which may occasionally exhibit tannin bleeding. Consideration must be taken if installing unsealed Weathertex products above porous or light coloured features.NOTE: Natural only- butt join not permitted with pre-primed. Alcor Flashing 2mm gap2.4.4HORIZONTAL JOININGHorizontal joins must be flashed using the Aluminium Z Flashing or Small Aluminium Z Flashing, refer to the Accessories Section. All horizontal joins must be supported by a double or rotated nogging. Install the accessory first before fastening off the top edge of panels.The standard Trimtec Z Flashing (instead of small Z Flashing) should be used where relevant between storeys to allow for frame settling and floor compression. The top panels should be installed such that the bottom of these panels rest on the spacer bead of the z flashing. Install successive panels in the same way using the Z-flashing for horizontal joints.NOTE:for natural Weathergroove ensure the Alcor flashing for the vertical join runs under the Z flashing.Weathertex 25'
