The steel door model Lucerne 1 from Erkado offers advanced technology and aesthetics that integrate modern design with the functionality necessary for today's homes. The door is made of galvanized steel sheet and coated with PVC veneer, which guarantees its high resistance to weather conditions and UV radiation. Available thermal insulation options, ranging from Ud=0.60 W/(m2K) to Ud=0.77 W/(m2K), allow the product to be tailored to meet the individual energy needs of any home, while finishing options such as LABEL BLACK and LABEL INOX add an elegant touch with subtly three-dimensional decorative panels.

Each model in the Lucerne 1 series has an RC2 burglary rating, providing a higher level of security, making it an ideal choice for those looking for an exterior door that combines security with care for the environment. The door leaf is filled with polyurethane foam, which provides excellent thermal insulation, and a system of three-post hinges with 3D adjustment guarantees easy and durable operation. The doorframes, available in aluminum or steel, further enhance the strength and aesthetic qualities of the product.
