UD 15 interior doors — new for 2025 from ET GROUP
The Unity Light DESIGN line is a contemporary addition to the popular Unity Light collection. The new arrivals for 2025 extend the collection with 30 of-the-moment models created for those who value aesthetics, comfort and quality.
The UD 15 interior door model is distinguished by central vertical grooving in the form of five parallel lines, visually drawing out the proportions of the leaf and lending it height. This understated detailing gives the door a contemporary, structured character while keeping it versatile.
The painted surface and crisp forms make UD 15 interior doors an ideal choice for modern, minimal, loft and scandi interiors, where clean lines and a restrained aesthetic matter.

Key advantages of the UNITY LIGHT collection

- FLUSH ARCHITRAVES
The face architraves sit flush with the door leaf, making the door more elegant, free of unnecessary recesses, and giving the design a sense of wholeness. - TELESCOPIC DOOR FRAME
As standard, the door set comes with telescopic door frames and rear architraves, allowing doors to be fitted in walls of the most common thicknesses, 100-125 mm. Where the wall is thicker than 125 mm, an extension is used. - SOLID TIMBER FRAME AND CARCASS
The door frame, architraves and leaf combine solid timber with moisture-resistant MDF. - ITALIAN HARDWARE
The door set is fitted with a dependable magnetic latch and concealed hinges of Italian manufacture. - WATER-BASED PAINTS
The doors are finished with high-quality, environmentally friendly water-based paints and primer from the European manufacturer AKZONOBEL. Once a special polymer primer has been applied, the door receives 2 coats for a more durable finish.
