Capex bars, from Irish supplier Exitex, are slightly raised, aluminium profiles that have a strip of gasket running along either side of the bar. They are most often used lying flat, running over the join where two sheets meet on a rafter, however they can also be used standing vertically where sheets are being used in a greenhouse or outhouse / shed application.
