Removable inspection port with butterfly bolts.
Although it was not included in the original drawings, we received an urgent request from the customer, and since the ready-made products could not meet the timeline, there was also a request to ensure that the appearance was not compromised. We designed it using bending processing, which allows for size adjustments and makes it possible to install it anywhere.

Even after inspection, the insulation and airtightness remain the same. An essential item for the bathroom area.
The Kiso inspection opening is the optimal item to be installed under the bathrooms of long-term excellent housing and next-generation energy-efficient homes. The inspection opening itself has insulation performance, and since the opening and closing lid is equipped with airtight material, its insulation and airtightness remain unchanged no matter how many times it is opened and closed. Even after repeatedly inspecting the bathroom section, its performance does not deteriorate. Installation is also easy; it can simply be set in the formwork in advance during the concrete pouring for the rise. *There is also a "pipe-compatible type" that allows for drilling holes for piping.
