Heat management in the shed is urgent!

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, 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.

Measures against heat in the shed! Discharges accumulated heat and improves cooling efficiency! Effective against humidity, condensation, and VOCs!

Modern homes have advanced in high airtightness and high insulation, resulting in issues such as heat accumulation in attics during hot seasons, which decreases air conditioning efficiency. "Attic Ventilation Wind Helper" helps improve air conditioning performance by forcibly expelling heat from the attic and is also effective in preventing condensation and addressing VOCs. We will present a demonstration unit, so please contact us for conditions and details. *The demo 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 begun to raise concerns 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 warning signal for your home. 【Let's check together】 ■ It's cool outside, but the room is stuffy ■ Air conditioning is ineffective ■ Many uncomfortable nights ■ Mold has appeared on the ceiling or in closets ■ 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 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 Future of Wind and Housing! A Discussion on the Current State of Attics in Japanese Homes.

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.

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 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.
