Washi Reform Honpo (Tanimoto Fusuma Koshoku Co., Ltd. / Osaka Prefecture) has announced the addition of new designs to its aluminum interior sliding door that can be installed utilizing existing fusuma and shoji frames.

The company's aluminum sliding door is characterized by its ability to be installed without removing the existing frames in rooms with old fusuma or shoji. With the addition of new designs, it can now accommodate a wider range of interior needs.

## Growing Demand for Japanese Room Renovations and Challenges in Fixture Replacement

In recent years, with the increase in purchases of used homes and DIY home renovations, the demand for arranging Japanese-style rooms into modern spaces has been growing.

However, replacing interior doors and sliding doors often requires removing the existing frame, leading to challenges such as:

* High construction costs
* Long construction periods
* Difficulty in renovating while occupied

In response to these issues, the company has been developing aluminum sliding doors that can be installed utilizing existing fusuma and shoji frames since 2008, proposing a new form of interior renovation that does not involve construction.

## Unique Design Compatible with Thin Fusuma Grooves

This product adopts a design tailored to the fusuma and shoji frames commonly used in Japanese homes.

Notably, it is characterized by its compatibility with "thin fusuma grooves," which have been difficult to accommodate with conventional aluminum sliding doors.

This makes it possible to replace fusuma and shoji with aluminum sliding doors in places where previously only fusuma or shoji could be installed, improving durability and significantly changing the impression of the space.

## Installable on the Day of Delivery with Included Rails
