The extensive range of Renderplas PVCu beading has been reapproved by the British Board of Agrément (BBA). And Renderplas movement joints are the only movement joints that the BBA have certified as compliant with the relevant building standard. This is welcome for construction industry professionals tasked with specifying render materials or constructing wall build-ups. The construction supply chain depends on BBA certificates to set the bar for construction quality. They are only awarded once a range of tests and analyses have been completed including checks on structural integrity, durability, and maintenance requirements. In the case of Renderplas, the BBA states that Renderplas uPVC beads are proven to be suitable for fixing external rendering to walls made up of masonry, dense concrete, or timber-frame. They can be installed by a competent general builder experienced in external rendering, and that Renderplas beading is resistant to mechanical damage.
