    Worldwide warranty concept for RENOLIT EXOFOL customers

    Worms, July 2, 2019 – Long warranty periods are a symbol of high product quality, reliability and proven durability. For decades, the RENOLIT Group has been known for its uncompromising quality policy, which enables them to offer customers a high level of product performance and safety, and therefore long-term warranties. It is now more than 20 years since the introduction of RENOLIT EXOFOL FX.

    The length of a warranty period depends on two factors: the quality grade of RENOLIT EXOFOL product chosen and the climatic conditions in which they are used. "In order to make this critical risk factor calculable, we have divided the world map into different country groups," explains Stefan Friedrich, head of the RENOLIT EXTERIOR business unit.

    RENOLIT EXOFOL films are tested outdoors in three different climate zones worldwide for decades to determine their performance.

    Tough tests

    The three film qualities RENOLIT EXOFOL MX, RENOLIT EXOFOL PX and RENOLIT EXOFOL FX are designed for use in different environments and have been tested over many years both in the laboratory and under natural climatic conditions. The products are tested in accordance with the RAL GZ 716 test standard issued by the Gütegemeinschaft Kunststoff-Fensterprofilsysteme (Quality Assurance for Plastic Window Profile Systems), which stipulates a product must successfully pass artificial weathering to class M20 requirements of 20 gigajoules per square metre of energy absorption without damage (exposure of around 10,000 hours using Xenon irradiation). But RENOLIT does even more in the pursuit of performance: "We always test our products to the point of destruction, so that we know their actual performance," says Dr. Dirk Heukelbach, Head of R&D at RENOLIT EXTERIOR “which is considerably higher than the standard requires.” Even the classic product RENOLIT EXOFOL MX can withstand up to 30 gigajoules per square meter; up to 40 gigajoules for RENOLIT EXOFOL PX and as much as 50 gigajoules for RENOLIT EXOFOL FX. This means that the premium product would belong, theoretically speaking, to an M50 weathering class, if it existed.

    Based on these test results, in 2018 the company revised its warranty periods. As a result, RENOLIT EXOFOL PX is extended up to ten years, twice as long as before, in Morocco, Algeria, Turkey and its neighbouring countries, and in China and South America. The warranty period for RENOLIT EXOFOL FX is now uniform worldwide up to 20 years.

     

    Complex principles

    RENOLIT has put its more than 35 years of experience to work when developing these high-performance films. The base film of RENOLIT EXOFOL PX consists of raw materials with a plasticizer-free PVC formulation. A specially developed polyacrylate transparent top layer protects both the printing ink and the base film. Highly efficient UV absorbers work more efficiently because they are not affected by plasticizer migration.

    The premium product RENOLIT EXOFOL FX is manufactured on a base acrylic film and is additionally enhanced with a coating of polyvinylidene fluoride (PVDF). Its low surface tension protects the film from dirt and chemicals and makes it insensitive to environmental influences or wilful attacks such as graffiti.

    In addition, all RENOLIT EXOFOL films benefit from Solar Shield Technology (SST). IR-reflecting colour pigments reduce the temperature differences between the outer and inner profile surfaces. In this way, the profiles retain their shape and windows and doors retain their exact fit.
