A House Like a Thermos?

“Essays in Idleness” was written in the Kamakura period. In it, Yoshida Kenko says that “when building a house, priority should be given to its comfort in summer.” However, in modern Japan, it is comfort not only in summer but also in winter that is considered when building a house.
As proof, we are seeing the phrase “a house like a thermos” when selling new homes. What this means is houses completely sealed in by insulation, in the floors, walls, and ceilings. Thanks to this insulation, the whole house can be kept at a set temperature, and winters can be passed in comfort as well. Also, as the insulation prevents the air warmed or cooled by the air conditioners from escaping the house, it helps save on power bills.
This insulation comes in many different forms, including expanded plastics and fibrous plastics. One of these types is Kaneka’s “Kanelite Foam” with a track record of over forty years. 
Kanelite Foam is an expanded plastic insulation material, colored a warm light beige. As it absorbs almost no water or moisture, the great enemies of insulation, its insulating properties will last for many, many years. In addition, its ease of working means that it’s also used as insulation in Japanese-style rooms, in the cores of tatami mats. Also, in 2001 we were the first in the world to succeed in developing products that used non-CFC, non-halogen foaming agents. This helps us contribute to protecting the ozone layer and preventing global warming.
Up until now, insulation has not always been a required specification when building a house. However, in view of global warming and reducing energy use, Japan is scheduled to phase in mandatory insulation in stages, with a final goal of 2020. Insulation is bound to become more and more important a material. Through insulation, Kaneka will continue to support your desires to live comfortably.
