UD 12 interior doors — new for 2025 from ET GROUP
The Unity Light DESIGN line is a contemporary addition to the popular Unity Light collection. The 2025 arrivals extend the collection with 30 on-trend models created for those who appreciate aesthetics, comfort and quality.
Soft forms have quickly come into fashion, and slender arches now fill the pages of architecture and design publications. Whole buildings take the form of classical semicircular arches as the basis of their architectural concept.
In the UD 12 interior door model, ET GROUP's designers have delicately set a semicircular arch within a rectangular leaf, creating an elegant nod to the classical without excessive ornament.
A smooth surface, minimalism and the graceful outline of the arch make these doors light, visually airy and versatile enough for interiors in the Japandi, Wabi-Sabi, Soft Minimalism, Neo Classic or Contemporary styles.
The Unity Light door collection opens up new possibilities for your interior – the models can be produced in the following formats:
- Double doors
- Sliding doors
1. The door is finished in the base white colour.
2. Hardware is available in white, black or grey.
3. The aluminium leaf frame is available in black only and is supplied with black hardware.
4. Standard door sizes are 800x2000 mm and 700x2000 mm. For the 600x2000 mm size the dispatch time is longer.
5. A telescopic extension piece is available separately in 4 sizes.
Key benefits of the UNITY LIGHT collection

- FLUSH ARCHITRAVES
The face architraves are set flush with the door leaf, giving the door a sleeker look without unnecessary recesses and lending the design a sense of wholeness. - TELESCOPIC DOOR FRAME
As standard, the door set comes with telescopic door frames and rear architraves, allowing the doors to be fitted in walls within the most common thickness range of 100-125 mm. Where the wall is thicker than 125 mm, an extension piece is used. - SOLID TIMBER FRAME AND CORE
The door frame, architraves and leaf are made from a combination of solid timber and moisture-resistant MDF. - ITALIAN HARDWARE
The door set is fitted with a dependable magnetic latch and Italian-made concealed hinges. - WATER-BASED PAINTS
The doors are finished with high-quality, environmentally friendly water-based paints and primer from the European manufacturer AKZONOBEL. After a special polymer primer is applied, the door receives 2 coats of paint for a more durable finish.
