Headquartered in Sapporo, Nichidan Inc. is a world-leading total insulation company that works on
many installation projects for Japan’s top five general construction companies. Since 2017, Nichidan
Inc. has been using Zero-Freon™ ER-X, the ASAHI YUKIZAI insulation foam that utilizes HRO gas, a new
foaming agent. We have a shared desire to be environmentally friendly, and are committed to a joint
quest for excellent insulating materials that transcends the line between manufacturer and user.
President Kenji Kitagawa spoke to us about that desire.
Environmental Issues and the Current State of Insulating Materials
Our company carries out insulating work in a wide range of specialized areas; not just in buildings,
but also in refrigerator trucks, large-scale refrigerators, and tunnel interiors. Up until recently
we had prioritized costs, an approach that is still deeply rooted in our industry. However, I had
felt from an early stage that our industry would have no future if we continued to neglect the
environmental aspects and simply focus on cost. At the same time, without insulation there would
inevitably be even greater use of heat sources, which is a factor in global warming. Nevertheless, I
find it unacceptable that such indispensable insulating materials utilize foaming agents which
damage the environment. Global warming is becoming more and more serious with every passing year
and, in fact, most of the major clients we do business with have changed their attitude to an
approach which emphasizes not just cost but also “environmentally friendly installation work.”
Around six years ago, we independently sourced from America materials that have a low impact on
global warming. We carried out a series of tests, and switched over completely to them around three
years ago.
ASAHI YUKIZAI’s Enthusiasm and Corporate Efforts Defy Conventional Wisdom
Although we had changed our approach due to concerns about the natural environment, the process from
materials to manufacturing our products was requiring a lot of time and money. It was around that
time that an ASAHI YUKIZAI sales rep asked if we were willing to try out their product. Based on the
test results, we decided that we had no use for the product at that time. However, when I was
greatly impressed when the sales rep responded to our refusal with the words, “We want to work with
you to make this a better product.” The following week two ASAHI YUKIZAI engineers came to our
company, listened to what our shop floor staff had to say, and improved the quality of the product
at an incredible rate of speed. We then engaged in a series of brainstorming sessions and, after
countless tests, Zero-Freon™ ER-X was born. Up until then the conventional wisdom was that the
better the performance of insulating material, the worse it was for the environment. It was
generally held that it would be impossible to develop an environmentally friendly insulating
material with excellent insulating properties. And that however good a product was developed, if it
was expensive, construction companies wouldn’t be able to use it even if they wanted to. This
revolutionary insulating material became commercially viable thanks to the enthusiasm of the ASAHI
YUKIZAI engineers, and to the company’s efforts with regard to cost. We do a lot of our work on
large-scale constructions, so we source a huge amount of materials. I think that was also to our
mutual advantage. More than 80% of our sales come from urethane foam insulation work, and we utilize
Zero-Freon™ ER-X in half of those projects.

Our Two Companies United in a Quest for Quality
Zero-Freon™ ER-X is not just environmentally friendly as a product that doesn’t use freon gas, which
destroys the ozone layer; it is also a superb product with excellent insulating performance. In
addition, the ASAHI YUKIZAI’s proprietary device used to spray the foaming agent dramatically
improves on-site workability. It has a unique mechanism that ensures there are no seams in the
finish, which makes for excellent airtightness. Our skilled workers are impressed by how easy it is
to use. Better efficiency means less material wasted, which results in lower costs. However, if
something is used by 100 skilled workers, there will inevitably be slight differences in how usable
they find it and in their skills. In the installation industry we regard a product as
“half-finished” when it has been made by its manufacturer; it only becomes a “complete product” on
site. ASAHI YUKIZAI don’t regard their task as finished once they have made the sale. Reps come on
site to check points such as how our skilled workers are doing the spraying, and they look at things
from the user’s perspective, offering advice on how the product can be used for a particular task,
or how to improve its use.
Here at Nichidan we always think about what we can do to make our
customers happy. In our quest for stable quality we study up on materials as intensively as their
manufacturers do, so we’re probably considered to be a very stringent company by other people in our
industry. And so we are. But ASAHI YUKIZAI is an important partner who accepts that about us, and
deals sincerely and swiftly with any issues that arise. I hope that we will continue to work in
tandem to build a bright future for both our companies.
