Rolltech warm edge benefits


The Chromatech Plus stainless steel profile has been designed by Rolltech to guarantee excellent performance in insulated glass. Its special design and technical features make it one of the world’s most resistant and stable warm edge profiles, says the company.

The strength of stainless steel makes Chromatech Plus an extremely stable profile with a long lifespan, it is claimed. 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 extremely low and 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.

There are other interesting properties that stainless steel lends to this innovative profile. Chromatech Plus significantly improves gas retention in IG units, it is claimed. The design introduced by Rolltech for this profile is also unique. Chromatech Plus has a very special shape that allows the thickness of the metal to be slimmed up to 0.15 mm: the thickness of the steel is thus reduced and can guarantee an extremely low level of heat transfer, optimising its performance versus that of profiles made of the same material but with conventional shapes.
