Underfloor ventilation unit "Kazetaro"

"Just because it's under the floor doesn't make it special. 'Ventilation' is an essential theme for the entire home." SEIHO Products Co., Ltd. (hereinafter, SEIHO) has published a new interview article themed on the importance of underfloor ventilation titled "It's not special just because it's under the floor. Ventilation is important for every part of the home." With over 45 years of experience in underfloor ventilation and moisture control, the company emphasizes that "the underfloor is an environment that greatly affects the durability of the entire home precisely because it is not visible." The article points out that while the underfloor is not easily visible to residents, the stagnation of moisture and heat can lead to wood decay, mold, and termite damage, all of which impact the durability of the home. It also explains that in recent years, as homes have become more airtight, the structure and airflow under the floor have diversified, making it crucial to accurately understand the current situation. The article shares insights gained from the field, including examples of drying after underfloor flooding, and conveys the necessity of appropriate responses based on the causes. SEIHO states that "the essence lies in not treating the underfloor as special, but in how to ensure ventilation for the entire home," and will continue to provide information for creating proper living environments.

Under the floor and in the attic... "Invisible spaces" are being reconsidered now The environment surrounding the housing industry has changed significantly in recent years. Rising timber prices, increased costs of equipment, a shortage of skilled workers, and prolonged delivery times are not temporary changes but are becoming entrenched as structural changes in the entire housing industry. Furthermore, in recent years, the global surge in resource prices, the depreciation of the yen, and rising logistics costs have compounded the situation, leading to a generally unstable environment for housing-related materials. What was once taken for granted—that "necessary materials can be obtained immediately when needed"—is no longer a given. Additionally, the construction and equipment industries continue to face a serious labor shortage. In particular, the aging of veteran craftsmen who support the field is progressing year by year, while securing young talent is not easy. As a result, situations such as difficulty in scheduling construction dates, longer waiting periods until construction, and limited availability of contractors in certain regions are increasingly common nationwide. In the housing industry, there is a growing sentiment that "construction plans cannot be made with the same sense as before," whether for new builds or renovations, which is becoming the norm across the country.

■Live Inspection Start Our company conducts inspections to provide our clients with a deeper understanding of the effectiveness, safety, and installation information of the products they sell. This includes visits to our simulation studio, experimental laboratory, test house, and production line. By observing the visualization of product effects, safety tests, and durability test scenes, we have received feedback such as "I have gained a deeper knowledge of the products" and "I can confidently propose to end users." We are pleased to announce the launch of our 'Remote Live Inspection Service,' focusing on smoke simulation and security systems, which have been the main features of our inspections. Taking into account feedback such as "I am interested, but it's difficult to come to Fukuoka due to the distance" and "It's challenging to coordinate schedules for multiple people," the content will be a condensed version, but we will provide an interactive explanation similar to what you would experience in person. 【Flow of Remote Inspection】 ■ For underfloor ventilation... Approximately 30 minutes ■ For security... Approximately 20 minutes ■ Q&A... About 10 minutes

We highly recommend that customers who have already installed moisture control materials (such as bamboo charcoal) consider adding a subfloor ventilation fan. We will compare and verify the moisture control effects/performance of using only subfloor moisture control agents (bamboo charcoal) versus using both subfloor moisture control agents and mechanical ventilation through moisture absorption and desorption tests. *The operation time of the ventilation fan is under desorption conditions. By adding a ventilation fan to the subfloor where bamboo charcoal mats are installed, we confirmed improvements in ventilation and airflow effects, leading to enhanced moisture absorption and release efficiency of the bamboo charcoal mats and reduced drying time. Additionally, it is expected that the combined use of the ventilation fan will further improve moisture control performance, leading to a decrease in subfloor humidity and enhanced drying effects on wood moisture content.
