The D-Lite D Board method involves manufacturing D-Lite wrapped with 3M TM Di-Noc TM film at the factory, and then installing it on-site as a non-combustible decorative panel with necessary processing. In this case, a contractor with experience in installing interior bath panels in residential settings took on this method for the first time, completing the installation of approximately 15m² of corridor wall in the office with a team of five in one day. D-Lite is lightweight and easy to handle like wood, and can be easily processed with common tools such as circular saws, hand saws, cutters, and sandpaper, making on-site size adjustments and fitting straightforward. In addition to the uniform and beautiful finish characteristic of factory production, the cross joints are also easy to achieve sharply, and it was evaluated by the construction team that even those without experience could install it without issues, and that it is lightweight and less burdensome.

The D-Lite D Board method involves manufacturing D-Lite wrapped with 3M TM DiNOC TM film in the factory, and then installing it on-site as non-combustible decorative panels with necessary processing. One of its features is that it allows for a uniform and beautiful finish since the panels are produced in the factory. Additionally, compared to methods that apply the film on-site, it makes it easier to achieve sharp cross joints. The D-Lite used as the base material is a lightweight, easy-to-handle proprietary material from DAIKEN, similar to wood. It can be easily processed with common tools such as circular saws, hand saws, cutters, and sandpaper, making it convenient for size adjustments and fitting on-site. A significant feature of the D-Lite D Board method is that the edges processed during adjustments can be finished with paint. This contributes to reducing work time, minimizing rework risks, and stabilizing construction quality.

【Comparison of Factory Application / D Board Method and On-Site Application Method in Video】 The comparison video digest presented in this content illustrates the differences in workability between the method of applying 3M TM Di-Noc TM film wrapped on all sides in a factory before installation on-site (Factory Application / D Board Method) and the method of applying 3M TM Di-Noc TM film on-site after first installing the calcium silicate board (On-Site Application). Using panels approximately the size of A4, we compare the differences in work time, processes, and finishes (joints and edges) under the same conditions. In the On-Site Application, in addition to the installation of the substrate board (by board craftsmen), the application of Di-Noc on-site (by Di-Noc craftsmen) is required, which tends to result in longer work times. On the other hand, when using panels with 3M TM Di-Noc TM film applied in the factory, the focus on-site is primarily on panel installation, simplifying the process. Furthermore, if the base material of the D Board used here is "Dailight D Board," which utilizes the workability of the non-combustible base material Dailight, it can be proposed as a D Board method that allows for easier on-site adjustments by carpenters and decorative panel craftsmen. Please use this as a comparison content to consider the adoption of methods and selection of base materials.

It is possible to contribute to various social issues and needs such as the realization of a low-carbon society, the decrease in the workforce, and preparedness for natural disasters. BIM compatibility is also available. This is a construction method that assembles steel T-bars into a grid and drops in the rock wool decorative sound-absorbing panel "Dairotong Grid." The grid ceiling sizes are 600mm square and 640mm square. It can also be used in properties that require clearance between the ceiling and walls. There are specifications available that can be used in data centers as well. 【Features of the Grid Ceiling】 Compared to conventional ceiling construction methods: - Reduction of inserts (suspension bolts) + reduction of interference with equipment and ducts - Realization of construction efficiency through reduced construction work - Easy seismic reinforcement due to the fitting type of joints - High maintenance due to the absence of inspection openings - Minimal types and quantities of waste generated on-site - Environmental consideration and recycling compatibility, as no adhesive is used during ceiling panel installation, making recycling of ceiling panels easy (contributing to a sustainable society)

The D Board method involves laminating 3M's 3M TM Di-Noc TM film onto a non-combustible substrate in the factory and then installing it on walls at the construction site. The Dailight D Board method uses a non-combustible material called 'Dailight,' made from DAIKEN's mineral fibers and volcanic ash glass materials, as the substrate. *Please refer to the materials below. 【Conventional D Board Method】 By manufacturing all boards in the factory and installing the completed boards, on-site work can be made more efficient. Since processing boards on-site is difficult, precise pre-measurement is necessary for board production. 【Dailight D Board Method】 Layout and board production are done based on drawings. Dailight has very high workability, allowing for on-site processing such as cutting edge boards and touch-up painting, which reduces the pre-measurement process and significantly shortens the overall delivery time. Since there is no film application work on-site, it is also recommended for customers who have never used the conventional D Board method!

■ By combining with other building materials (gypsum board, sound-absorbing wool F), we achieve D-30 to D-40. ■ It can be used in a wide range of properties, from public commercial facilities with fireproof specifications to residential buildings. * The sound insulation rating refers to the sound pressure level difference in six frequency bands at center frequencies of 125, 250, 500, 1000, 2000, and 4000 Hz. Specifically, it represents the sound pressure level difference between the sound entering the wall (incident sound) and the sound passing through the wall (transmitted sound) expressed in decibels (dB), known as the transmission loss represented by 'D value'. (Example) Incident sound level (100dB) - transmitted sound level (60dB) = transmission loss (40dB) ... resulting in D value (D-40).

The corridors of high-rise office buildings are important areas for evacuation routes, but their ceilings face challenges in terms of seismic resistance and construction. - Even if we want to implement seismic specifications, it is often necessary to lower the seismic level because ducts and equipment hinder the installation of seismic braces. - The corridors are narrow for construction, and ducts are concentrated in the ceiling space, making construction efficiency very poor. Since this area is crucial for the movement of people and materials, we want to improve construction efficiency and shorten the overall construction period. The corridor ceiling system "Mamoroka" can simultaneously address the above seismic measures and improve construction efficiency. 【Features】 1. The structure supports the ceiling with walls, eliminating the need for hanging bolts and seismic braces. 2. Simple installation by fitting furring channels into the furring supports attached to the walls. *For more details, please contact us or download the catalog.
