Underfloor Ventilation Series "Turbine Unit Type Bi"

"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 around 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." The company emphasizes that "the underfloor area, being unseen, significantly affects the durability of the entire home," based on over 45 years of experience in underfloor ventilation and moisture control. The article points out that while the underfloor area 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, such as examples of drying after underfloor flooding, and conveys the necessity for appropriate responses based on the causes. SEIHO states, "The essence lies not in 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 lumber prices, increases in equipment costs, a shortage of skilled workers, and prolonged delivery times are all contributing factors. These changes are not temporary; they are becoming established as structural changes within 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 an overall instability in housing-related materials. The environment where it was once taken for granted that "necessary materials would be readily available when needed" is no longer a certainty. 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 before construction, and limited availability of contractors in certain regions are increasingly common nationwide. In the housing industry, there is now a growing sentiment that "construction plans cannot be made with the same sense as before," whether for new builds or renovations.
