Chromatech Plus stainless steel profile has been designed by Danish manufacturer Rolltech to guarantee, says the company, excellent performance in IG. The strength of stainless steel makes Chromatech Plus an extremely stable profile with a long lifespan. These features make for an extremely stable frame which is a must-have in large-size, important IG glass. The thermal expansion coefficient (elongation) of a stainless steel profile is, in fact, extremely low & very similar to that of glass. As a result of these very properties, the sealants are subjected to less strain in insulating glass that uses Chromatech Plus when the outside temperature changes. The result is a more stable system, which, in turn, means that all risks are eliminated. Thanks to the use of stainless steel, Chromatech Plus significantly improves gas retention in IG units, thus maintaining the same levels of thermal performance over a long period of time. The design introduced by Rolltech for this profile is also unique. In fact, Chromatech Plus has a very special shape that allows the thickness of the metal to be slimmed up to 0.15mm, thus reducing the thickness of the steel and therefore guaranteeing an extremely low level of heat conduction, optimizing its performance compared to that of profiles made of the same material but with conventional shapes.
