In this discussion, we explain 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 become common to adopt it as a standard specification for new constructions. However, through many years of promotional activities, there is an impression that attic ventilation is perceived only as a measure against heat by both businesses and end users. *For more details about the discussion, you can view the PDF materials or related links. Please feel free to contact us for more information.*

• Ventilation system

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, for example, exceeds 30°C in the attic. 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 climate has cooled, 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.

• Ventilation and smoke exhaust equipment

In 2020, the "mandatory energy-saving standards for housing" are scheduled to be implemented, and it is expected that Japanese housing 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-type condensation while simultaneously preventing summer-type condensation. *For more details, please refer to the PDF document or feel free to contact us.

It detects the temperature in the attic with a temperature sensor and allows for switching between strong and weak operation. Additionally, it features a condensation mode that is effective for removing condensation. 【Features】 ■ Discharges hot air and improves cooling efficiency - Reduces excessive use of air conditioning, benefiting family health and saving on electricity bills. ■ Shuts out condensation - Actively circulates air in the attic to minimize temperature differences, eliminating the causes of condensation and prolonging the life of the building. ■ Supports the health of the family and home - With high ventilation capacity, it effectively expels formaldehyde and VOCs from the attic to the outdoors. *For more details, please refer to the PDF document or feel free to contact us.

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 the energy-saving effect. Additionally, a comparison of temperatures between the attic, indoors, and the human body using a thermotracer showed that with a ventilation system, the temperature of wooden components such as beams in the attic and the ceiling surface was lower, and the temperature difference indoors was reduced with height. *Varies depending on conditions and the air conditioner's capacity and efficiency. 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). ■ The energy-saving effect was confirmed. *For more details, please refer to the PDF document or feel free to contact us.

The humidity indoors is visible as condensation, so by opening windows or using exhaust fans, the trapped moisture can be expelled outdoors. But did you know that there is also a lot of this moisture under the floor? Modern homes have achieved excellent comfort through high airtightness and high insulation. However, as the structural reinforcement of foundations has progressed, the crawl spaces have become lower and the compartments more complex, making ventilation under the floor more difficult. Just checking one of the items below does not mean you can relax. If any one of them applies, it is a danger signal for your home. 【Let’s check together】 ■ When you open the underfloor storage or tatami mats, there is a musty smell. ■ There are black stains on the walls near the closet or dresser. ■ There is always condensation dripping from the windows or the lower part of the window sills. ■ The tatami feels damp and spongy. ■ The floor creaks, or you occasionally see winged ants in places like the bathroom. ■ You often get bitten by mites. ■ The floorboards feel sticky. ■ The cloth foundation is always damp or has moss growing on it. ■ There are cracks in the cloth foundation. *For more details, please refer to the PDF document or feel free to contact us.
