Arstyl LS1 is a 2.40 m long corner profile that can be used for window soffits in new buildings or renovation projects. It is mainly employed in conjunction with plasterboard. The tapered corner makes it possible to achieve a seamless transition from the soffit to the plasterboard. That further prevents potential fissures in the corners. Made of high-density polyurethane, the profile is quick and easy to install, highly durable and, in addition, has insulating properties.
