Surface Finishes

Our hardware is used in windows throughout the world, which means that it must be able to withstand a very wide range of climate conditions and environmental influences.

In order to do justice to our high quality claims in this respect, in addition to strict quality checks in development and production we also particularly depend on optimum component quality, and this enables us to provide a 10-year functional warranty on all Roto NT components.

We treat all Roto NT hardware components with the unique RotoSil Nano coating technology as standard. This involves galvanizing the basic material, passivating it with nano particles and then visually sealing it.

  • Optimum corrosion protection with unique self-healing in the event of minor scratches
  • Nano particles tension the surface and make it extremely resistant to aggressive substances
  • RotoSil Nano displays “extraordinarily high resistance to red-coloured rust” and thereby exceeds what is required by the standard  DIN EN 13126/8 Class 4 as per EN 1670:2007 (D) many times over
  • The coating technology is free of chromium (VI) compounds, is also environmentally safe and poses no health risks
  • The components have an even, matt silver appearance

Our Roto NT special surface  is used for maximum resistance to  extreme environmental influences, for example in swimming baths with chlorine / ozone vapours, in cattle stables with heavy ammoniac gas formation or in conjunction with accoya wood windows with acetic content.

Following basic galvanic sealing, each individual NT component is given a special top coat of varnish.

  • Maximum corrosion protection for long-term functionality and durability under extreme conditions
  • Robust against aggressive acids, gases and alkalis
  • The Roto NT special surface coating displays “extraordinarily high corrosion resistance under extraordinarily hard conditions”, and thereby exceeds what is required by the standard  DIN EN 13126/8 Class 5 (highest class) as per EN 1670:2007 (D) many times over
  • The components have an even, matt silver appearance
