Our Esterno E01 door is a white exterior door with glazing. For the glass, we aim for an optimal U-value of 1.1 W/(m²·K), using a 4/16/4 configuration.

With 5 chambers integrated into the door profile, our exterior doors meet current insulation standards and allow us to offer doors with a Ud-value of 1.4 W/(m²·K). The door’s stability is guaranteed thanks to galvanized steel reinforcement.

At Solid, safety comes first. That’s why we equip our exterior doors with a 5-point anti-burglary lock. The multipoint lock secures the door at 5 points in the frame: in the center via a cylinder, and at the other 4 points with rollers that provide anti-burglary protection, making it very difficult to remove the door from the frame.

Good to know: Solid follows the DIN standard to determine the swing direction of exterior doors. Instead of providing clear opening dimensions, we always give the manufacturing dimensions. This ensures precise and consistent sizing, perfectly aligned with our production processes and our customers’ expectations.
