The Origins of Scraped Render

The Ori­gin of PVC Beads for Scraped Renders

In 1990, Ren­der­plas became the first com­pany in Europe to develop a range of beads in UPVC (as it was then known). Cor­ner beads in those days fol­lowed the design of a con­ven­tional roll-formed steel bead and was called a CB65 or CB45, accord­ing to the depth of the wing.

Dur­ing a meet­ing with Sno­cem Ltd in 1991, Ren­der­plas was intro­duced to their Dutch part­ner, a sup­plier of spe­cial­ist min­eral based ren­ders. These ren­ders, new to the UK, were scraped back before hard­en­ing to repli­cate rough sawn limestone.

Ren­der­plas entered into talks in 1993 to sup­ply Hol­land and Ger­many with its range of PVC beads. How­ever, it was soon appar­ent that there was a need for a cor­ner bead specif­i­cally designed for these scraped fin­ishes. The rea­son for this was that the arris of a con­ven­tional bead became too promi­nent after the 2-3mm of ren­der was scraped back and this was aes­thet­i­cally unac­cept­able. Ren­der­plas solved this prob­lem by devel­op­ing the EP-14, which became the first bead in the world to be spe­cially designed for scraped ren­ders. This same bead is now the Ren­der­plas CB15, the design of which has become the bench­mark for all other PVC bead manufacturers.

With Ren­der­plas set­ting the stan­dards for the last 21 years, the Aus­tralian build­ing trade can now expe­ri­ence the ben­e­fits that PVC tech­nol­ogy brings to fin­ished renders.
