Installing Moderra Units

Once you have installed your initial corner, you can now apply the Moderra Concrete Siding units. Moderra's innovative H-Channel technology allows the siding units to be installed vertically into "columns".

1. Attach an H-Channel
   A Moderra column should always be started at a corner. If you are using Moderra Corners, you simply slide 8" Blocks into the existing H-Channel. (Fig. 14)
   
   
   If your wall does not involve a corner, start by affixing an H-Channel to the wall. Then slide the 8" Blocks into the H-Channel. This type of installation may require flashing to finish off the side of the Moderra wall.
   
   

Note: Moderra units should always be placed so that their Atmospheric Gasket and chamfer is pointing up.

2. Stack the Units
   While stacking the units, use a Trim Channel or 3/4 inch board as a spacer between the Moderra and the wall. This will make it easier to insert the next H-Channel once the column is built. (Fig. 15)
   
   
   Slide additional 8" Blocks into the attached H-Channel and tap into place with a rubber hammer. Level each block on the top and side to ensure a straight wall and to minimize seams between the units and columns. Sweep the top of each block to remove any dust or debris before installing the next unit.
   
   
   Note: Use metal shims when necessary to keep Moderra units level.






3. Attach Another H-Channel to Complete the Moderra Column
   Once you've reached your desired height, remove the Trim Channel or 3/4" spacer and slide the H-Channel into the installed units. Tap it securely into place with a rubber hammer. The flange should be pointing outward. (Fig. 16)
   
   
   Once the H-Channel is securely in place, attach it to the wall surface every 24 inches. For details, see Fastening Moderra.
   
   
   Continue to build additional Moderra columns using steps 1 through 3 until you have finished installing your Moderra wall.

Finishing with Moderra Sills


Note: When using a product other than the Moderra Sill Block, refer to that product's installation guidelines.


First, install flashing at the bottom of you existing siding. This will help to prevent moisture from falling behind your Moderra wall. (Fig. 17)


Next, apply a thin layer of Super-Stik concrete adhesive to the top of the Moderra columns and on the side of the Moderra Sill Block. This will secure the units into place. Set the Moderra Sill Block onto the glue and tap into place. Continue gluing and placing the Sill Blocks until finished. (Fig. 18)


At an outside or inside corner, fit the Moderra Sill Blocks with a 45-degree miter cut. Once the Sill units are all in place, your finished Moderra wall should look as follows. (Fig. 19)
