The PLANOTHERM designer front door from SMO BAUELEMENTE combines premium features with excellent thermal insulation, enhanced security, and a sophisticated design. Built on a high-quality 5-chamber uPVC system with an 82 mm frame depth and a foam-filled steel core, it ensures outstanding insulation performance. Flush-mounted panels create a seamless, modern exterior, while the 55 mm thick, highly insulating panel is firmly bonded to the door leaf for added stability and protection. This advanced construction helps keep interiors cool in summer and reduces heating costs in winter.
