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.
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.
