If you have a large opening, consisting of a window, then doors and another window then it’s best to use a Tpost design.
The shutters would come in one large frame with 2 vertical Tposts matching the centre door supports. This design would typically be split into four shutters, a single panel covering each window that opens independently. Then two shutters over the door area, that would be hinged from the vertical Tposts.
If you choose a tracked design for this type of door, the divisions or joints of the shutters would not align with the door joints as the windows tend to be smaller than the doors and track mounted shutters all have to be the same width, whereas Tposts allow each shutter to match the width of the door sections.
This style of French Door usually has just glass running from top to bottom, so it’s nice to match this with your shutter design so there are just louvres running from top to bottom.
You will still need a split in the hidden tilt mechanism and, by not having a rail, it will void the guarantee, unless you choose the Elite Plus shutters.
If your doors are just plain glass, but your side windows have a dividing rail, we would match the shutters to your door and not have a rail. We’d match the shutters to the window with a dividing rail. The door shutters would have louvres from top to bottom, with a split in the tilt mechanism, that would be in line with the rail on the side shutters.
Most customers would choose the Elite Plus shutter, as they allow you not to have a diving rail across the door and still be guaranteed. They are a thicker and stronger shutter and can made wider and taller than the normal Elite shutters.
Typically, there would be a 4-sided frame around the side shutters and a 3-sided frame over the door, so this means no bottom frame between the Tposts to avoid a trip hazard.
If you have two shutters between the Tposts, with a left right design, they would be guaranteed. But if you have four bi-folding shutters, without a bottom frame, it would void the guarantee.
Skirting board can either be removed to allow for the shutter frame to run down to the floor, or the frame can be cut around the skirting.
If the frame is cut, we would normally allow a shadow gap around the skirting board to match.
