Fixing boarding to walls and covering gaps

[atrose81]

Hi Guys,

I recently took over a St John Ambulance unit and the building is in need of some work.

It used to be an industrial unit and boards have been attached to the brick work to cover them up. The vertical gaps between the boards have then been covered with wooden pieces from floor to ceiling.

The boards are coming away from the walls so I need to screw them back into the brick work. Whilst doing this though I want to use something else to cover the gaps, can anyone suggest something better suited than wood ? Maybe some PVC type thing ?

in fact it looks like something like jointing strips would do but I want to scren the boards to the wall and then use something similar to cover the gaps and the screws.
