Addressing the heat issues in the shed is a matter of urgency!

Powerful ventilation to expel heat from the attic! A ventilation system that significantly reduces radiant heat caused by trapped heat in the attic!

The "Kaze no Suke Series" is a ventilation system suitable for heat management in attics. When this product is installed, a temperature sensor automatically starts forced ventilation when the set temperature is reached, for example, when the attic temperature exceeds 30°C. During the summer, outside air will continuously flow into the attic, preventing the rise and stagnation of attic temperatures. As a result, the amount of radiant heat transmitted indoors will also decrease, which can lead to raising the air conditioner's set temperature or shortening its operating time. We recommend installation after the cool season, so we suggest considering the introduction of a ventilation system for the next heat management measures. 【Features】 ■ Powerful ventilation expels attic heat and significantly reduces radiant heat ■ Effective against winter condensation in attics *For more details, please download the PDF or feel free to contact us.

Measures against heat in the attic! Expels accumulated heat and improves air conditioning efficiency! Effective against humidity, condensation, and VOCs!

Modern houses have become highly airtight and well-insulated, resulting in issues such as the heat accumulated in attics reducing air conditioning efficiency during hot seasons. "Attic Ventilation Wind Helper" helps to forcibly expel the heat from the attic, improving air conditioning performance and assisting with condensation and VOC measures. We will present a demonstration unit, so please contact us for details and conditions. *The demonstration schedule will be arranged separately. 【Effects】 ○ Expels heat from the attic, improving air conditioning efficiency ○ Shuts out condensation ○ Effectively expels formaldehyde and VOCs, which are causes of sick house syndrome, protecting the health of your family and home.

Introducing the importance of "attic ventilation" along with a checklist!

Originally, Japanese houses were designed to suit the hot and humid climate, featuring an open structure that allowed for good ventilation. However, modern homes have pursued comfort, leading to increased airtightness and insulation, which has resulted in some adverse effects in recent years. If only one of the following items is checked, it does not mean you can relax. If any apply, it is a danger signal for your home. 【Let's check together】 ■ It’s cool outside, but the room is stuffy ■ Air conditioning is not effective ■ Many uncomfortable nights ■ Mold has appeared on the ceiling or in the closet ■ The room smells musty ■ Eyes feel irritated ■ Children often cough ■ Condensation has appeared in the attic *For more details, please refer to the PDF document or feel free to contact us.

The reduction rate is approximately 15% to 23%! We confirmed energy-saving effects by ventilating the attic.

This experiment examines the "effect of indoor air conditioning electricity consumption." By ventilating the attic, the reduction rate of electricity consumption during air conditioning operation on sunny days was approximately 15% to 23% (*), confirming energy-saving effects. Additionally, a temperature comparison between the attic, indoors, and the human body using a thermotracer showed that with a ventilation system, the temperature of wooden parts such as beams and the ceiling in the attic was lower, and the temperature difference indoors was reduced by height. *Varies depending on conditions and the capacity/efficiency of the air conditioner Air conditioning operation time: 16:00 to 22:00 for 6 hours [Results of the indoor air conditioning electricity consumption effect experiment] ■ The reduction rate of electricity consumption during air conditioning operation was approximately 15% to 23% (on sunny days) ■ Energy-saving effects were confirmed *For more details, please refer to the PDF document or feel free to contact us.

The future of wind and housing! A discussion on the current state of attics in Japanese homes.

In this discussion, we explain the measures against humidity and condensation in attics, as well as the importance of ventilation. Our company launched the underfloor ventilation system in 1981, and two years later, we introduced the attic ventilation system. Since then, after several model changes, it has now become a standard specification for new constructions in some cases. However, through many years of promotional activities, there is an impression that attic ventilation is perceived by both businesses and end users solely as a measure against heat. *For detailed content of the discussion, you can view the PDF materials or related links.

Measures against condensation in summer! Condensation and corrosion within wall structures are often difficult to detect.

In 2020, the "mandatory energy-saving standards for housing" are scheduled to be implemented, and it is expected that Japanese homes will increasingly aim for high airtightness and high insulation. However, at the same time, measures against condensation during the summer must be considered. In a site where glass wool was filled using the 2x4 construction method and a vapor barrier was installed on the interior side, significant corrosion due to condensation occurred. It is believed that the interior became hot and humid, leading to condensation as it was cooled by the air conditioner on the inside. The hold-down hardware also showed white mold, and if corrosion progresses like this, it will pose problems for the durability of the building. This type of summer condensation particularly occurs in regions with high temperatures and humidity, like Japan. Therefore, it is necessary to implement sufficient measures against winter condensation while simultaneously preventing summer condensation. *For more details, please refer to the PDF document or feel free to contact us.

The "Mechanical Stitching Method" by Nichinichisui Road Machinery Co., Ltd. is a new technique that allows for the repair of metal cracks without the application of heat. By using special bolts and reinforcement plates, cracks are physically removed, and repairs are made without causing any thermal impact on the base material. Repairs can be carried out even in environments where open flames cannot be used. Since no heat is applied, the disassembly of equipment is minimized. ◎ For more details, please contact us. ◎ If a detailed technical explanation is needed, please contact us.

● The production time for cast prototypes can be shortened! Since model making is not required, the production time for prototypes, which previously took about a month, can be significantly reduced. ● Model costs can be reduced! By directly producing sand molds from 3D data, there is no need for model production costs. If changes to the model are necessary, they can be addressed by modifying the 3D data. ● Similar products with different shapes and dimensions can be prototyped simultaneously! Different products, such as similar shapes or varying dimensions, can be molded at the same time in one molding process. This allows for the verification of multiple types in a short period.
