The deciding factors for the introduction were "experiments (presentations)" and "research materials." The number of cooling devices was reduced from 7 to 1, and the number of employees with health issues has become zero, Igeta-do Co., Ltd.

What is the patented construction method "Sky Method" that is applied from the top of a folded plate roof?

Cuts approximately 97% of "radiant heat from the sun" that cannot be completely prevented by insulation materials. The 'Sky Method' is a patented technique that involves applying a heat-insulating sheet over a corrugated roof. 【Features of the Sky Method】 ■ Indoor temperature in summer decreases by about 11°C (maximum temperature difference based on experimental results) ■ Contributes to savings on air conditioning costs, prevention of product deterioration, and improvement of the working environment ■ Provides stable heat insulation effects regardless of the skill level of workers or weather conditions during installation ■ Effective against leaks ■ Uses a strong double-sided tape that does not peel off even in winds of 40 m/s ■ Patent obtained (No. 6598337) *For more details, please download the PDF.

"Under Construction of Ribbed Roof" | Ribbed Roof (Construction from Under the Roof)

The radiant heat emitted from the folded plate roof is significantly reduced by the reflection of the radiant heat by the inner thermal barrier S. This results in a lower perceived temperature. A lightweight steel frame is constructed under the folded plate roof, and the thermal barrier S (non-combustible certified product) is installed beneath it using tapping screws on the lightweight steel frame. *Working at heights or the installation of rolling scaffolding is required.

Installation of non-combustible certified Thermo Barrier S on the inner side of the roof in 'Slate Roof Under Construction'.

We would like to introduce the construction method "Under Slate Roof Installation" by Life Tech Co., Ltd. for factories and stores. Thermal Barrier S (fireproof certified product) is installed with tapping screws towards the steel frame's purlins under the slate roof. The thermal barrier S on the inside reflects the radiant heat emitted from the slate, significantly reducing the impact of radiant heat. This results in a lower perceived temperature. 【Features】 ■ The thermal barrier S on the inside reflects the radiant heat emitted from the slate. ■ Significantly reduces the impact of radiant heat. ■ Has the effect of lowering the perceived temperature. ■ There is a difference in the impact of radiant heat between areas with and without thermal barrier S installed. *For more details, please refer to the PDF document or feel free to contact us.

We have introduced our commercial aroma diffuser "Majesta Fragrance" at a karaoke bar located in the city. The model we installed is [MF-02S]. From the moment customers open the door, a gentle fragrance spreads throughout the store, enhancing the atmosphere. We hope to create a memorable store that customers will want to visit again through the use of fragrance. Majesta Fragrance is available for a free trial installation exclusively in the Kanto area. If you are interested in our fragrance services, please feel free to contact us.

We have introduced our Majesta Fragrance in the restrooms of a company located in the city. The model we implemented is the compact-sized MFmini. By adding fragrance to the clean space, we have created an environment where users can spend their time more comfortably. The restroom, which is used daily, has become a more pleasant and high-quality space.

Thank you very much for always using Majesta Fragrance. Our company will be open as usual during the Obon period. Please feel free to contact us for inquiries about scent arrangements or the introduction of commercial aroma diffusers.

High Strength, Low Cost: The Economic Advantages of Carbon Steel Frames Carbon steel is inherently strong, and this high structural strength ensures stable wind resistance while allowing for a simple support structure, reducing the need for extra components. This also lowers the wear rate during transportation, enabling further savings in material costs and installation expenses. Transportation and Construction: Streamlining the Entire Project The advantages of carbon steel frames are also evident in the transportation and construction phases. Standardized designs simplify on-site installation and shorten construction periods. For example, carbon steel frames can be packaged using a combination of wooden sticks and iron ties, improving unloading efficiency and increasing transport volume. This reduces construction time and labor costs, distributing the overall burden of the project across all stages. Technological Innovation: Breakthroughs in Corrosion Resistance With the evolution of material technology, the corrosion treatment of carbon steel frames has also significantly advanced. Grace Solar has adapted to the technological trends in process development, and all current carbon steel frames utilize AlMgZn coating. At the same time, to meet the special requirements of each project, our company offers custom options for hot-dip galvanizing.
