A frameless finish removes the visual break between the board and the wall around it, so the writing surface reads as part of the wall rather than a separate object mounted on top of it. This suits minimalist interiors where visual clutter is deliberately kept to a minimum.
The trade-off is a more demanding installation, since a frameless edge relies on the wall being flat and level to look genuinely seamless.
An all-glass or fully bonded frameless panel also simplifies cleaning, since there is no frame edge for dust or marker residue to gather along, which matters in a design-led office where the board is on constant display rather than tucked into a back-office room.
Offices considering this option should also budget extra time for the installation itself, since a frameless edge typically requires a more careful site survey and, in some cases, a backing panel behind the wall to guarantee the finished result actually sits flush once fitted.
