Ever since the Greenfell Tower tragedy, which killed 72 people, the installation of cavity barriers (used to inhibit the spread of smoke and fire in concealed spaces) has come under the microscope in the UK. Partly in response to this we've started modelling cavity barriers. This makes them a more prominent part of the design process and has helped me to put earlier thought into their arrangement. Instead of applying them as 2D objects latter in the process. It also provides the possibility of displaying them in 3D, in a 3D view or even on an elevation, with the outer wall components turned off. The problem is I've only been adding horizontal cavity barriers to the model, using the Slab object. At the moment I'm still relying on 2D for vertical cavity barriers. Because there's no suitable tool that comes to my mind that can conveniently model vertical cavity barriers and insert them into walls. And the Slab object is not particularly ideal for the horizontal barriers either, as it would be useful to be able to insert these into walls also. So I'd like a tool designed for this purpose.

Now that we have the very welcome Wall Closure feature I would love to have support for 'cavity closers'.** 'Cavity closers' are used in cavity wall construction around openings in the walls—in particular windows and doors—to protect against water ingress, damp, heat loss, condensation and smoke. In some types of construction they're also used to inhibit the spread of smoke and fire in concealed spaces; in the UK their name changes to Cavity Barrier in this case. I'd like to be able to show these on our 1:50 floor plans and sections.
