The interface between the decking and the door sill are often the subject of discussion between trades. We have categorised solutions into three options:
Utilising a walk on structural support to the door sill avoids the cutting in of decking boards (when butted up to the sill). However, some clients choose to get deck boards cut in to give a more consistent aesthetic appeal.
Such boards can be supported from either a structural door sill or from brackets fixed back to the rear member of the Cassette® frame.
For recesses deeper than a single deck board width (i.e. > 150mm), support is required from the building or façade structure. When supporting it from the building, we can incorporate support from the cast in anchors. Whether or not this is independent of the cast in element this must be thermally broken and properly weatherproofed.
