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.

High functionality and innovative design backed by data. A large high-volume type of Sirocco fan is adopted to more effectively stir the air under the floor and in the ceiling space. The high-volume air blows out in four directions. With a unique scroll shape that minimizes waste, it achieves about twice the wind reach distance compared to conventional types, with a diameter of about 9 meters (wind speed 0.5 m/s). The three-dimensional design with low air resistance and quiet operation smoothly draws in heavy, moisture-laden air. The body is made of lightweight and durable aluminum alloy, eliminating concerns about rust. The controller with a temperature sensor detects the temperature in the ceiling space and switches between strong and weak operation. The newly designed high-performance two-speed motor operates at high power when the ceiling temperature rises, effectively exhausting heat. It operates at low power when the temperature drops. 【Features】 ○ Effective for heat and condensation measures in attic spaces ○ Automatically operates by sensing temperature For more details, please contact us or download the catalog.

High functionality and innovative design backed by data. With a unique blower shape and intake design, it achieves approximately six times the static pressure compared to conventional models. The three-dimensional design with low air resistance and quiet operation effectively exhausts hot air. It can be easily installed by making a simple ∅100 hole in the ceiling, as it exhausts through a duct that can be freely extended and is connected to a pipe hood with a gable roof. 【Features】 ○ Effective for heat and condensation prevention in attics ○ Automatically operates by sensing temperature For more details, please contact us or download the catalog.

With a unique design, the "Stirring Blower" has become even more powerful. It employs a large silencer-type Sirocco fan that effectively stirs the efficiently drawn-in air with a high air volume. The strong airflow is directed in six directions. Thanks to its efficient scroll shape, it achieves an air delivery range of approximately 5 meters in diameter. The body is made of lightweight and durable aluminum alloy, so there is no worry about rust. 【Features】 ○ Effective for countering heat and condensation in attics ○ Automatically operates by sensing temperature For more details, please contact us or download the catalog.

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.

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 "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.

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.

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.

Introducing SEIHO's unique facilities, measuring devices, and instruments for conducting a wide range of tests, experiments, and measurements repeatedly.
