Oldroyd Xtf is the number one sustainable fireproof and waterproof solution for underground projects. Produced in Norway by specialist manufacturer Oldroyd, it contains only environmentally friendly raw materials and is thoroughly tested in challenging Norwegian and Faroese tunnels. Oldroyd Xtf membrane is tested according to the EN 13501 standard for ‘Fire classification of construction products and building elements - Part 1: Classification using data from reaction to fire tests’. As a result, the membrane is classified to B-s2.d0, meaning it completely prevents burning droplets when exposed to fire. Watch our Xtf fire testing videos for more information. Oldroyd are specialist UK product partners with Newton Waterproofing Systems, and the Oldroyd Xtf membrane is distributed exclusively in the UK via Newton.
