Miratap Co., Ltd., an online retailer of housing equipment, will launch "Liminal," an interior door that pursues a "noiseless" design, on Thursday, May 7, 2026. This design minimizes visual elements such as hardware and steps, allowing the door to naturally blend into the space. It adopts hidden hinges and embedded handles, and with an ultra-thin frame width of 5.5mm, it achieves a finish that integrates with the wall surface.

In recent years, with the spread of social media, opportunities to see completed housing examples and spatial expressions have increased. Along with this, home buyers and architects are now paying attention not only to floor plans and equipment but also to the details of finishes. Against this background, noiseless designs that eliminate as much waste as possible and make the space itself beautiful are attracting attention.
"Liminal," launched this time, is an interior door that thoroughly pursues a noiseless design. In general interior doors, the hardware called "hinges" that connects the door and the wall is exposed on the surface. "Liminal" adopts "hidden hinges" that conceal these hinges inside the door and "embedded handles." Furthermore, by unifying the hinges, door, and handles in the same color, the presence of hardware is eliminated, achieving a sense of unity with the space.
In addition, a unique structure minimizes the difference in level between the door and the wall, and the visible width (the width of the door frame visible from the front) is narrowed to an industry-leading 5.5mm*, achieving a beautiful finish that connects flush with the wall surface. We pursued an expression that integrates with the architectural space, where the door does not assert its presence. In addition to the standard black and white colors, light gray is also available. We focused on a color lineup that easily harmonizes with wallpaper and wall surfaces.
This interior door offers a new choice for designers and users who are particular about every detail of a space.
