We run a cram school (Juku), and had concerns about the noise and heat. After we coated GAINA, it become superbly quiet and the temperature was down. This changed our school into a comfortable environment. We were very surprised.

2. K family' house / Aichi Prefecture, Nagoya / Roof and Walls

Noise from outside was muted. We were amazed at GAINA's soundproofing effect. On top of that, the summer heat was lessened. We just coated GAINA on the roof and only two outside walls. The west facing staircase used to be very hot, the hot air had been stifling, now the heat is reduced. We were surprised that the winter cold was also reduced.

Interior walls are now scheduled to be coated with GAINA.

3. S family' house / Kagawa Prefecture, Takamatsu / Roof, Walls and Interior

Without using  air conditioning, it is very comfortable. Also, GAINA provides an excellent soundproofing effect. Busy roads (including a national highway) are near by and on the school route, however, we no longer hear much outside noise, not even the sound of rain on our roof.

36. Meat Aging Room Test

For meat aging, Gaina was applied inside a meat storage room in Korea.

The company's purpose for the luxury beef was to further improve the taste by exposing it to negative ions. They started by testing the room. Before Gaina's application, there was no negative ion mass.

Before / 0

After Gaina was applied, the test confirmed a significant negative ion mass increase. The company made the decision to apply Gaina in every meat aging room of their restaurants.

After / 1106

The process of aging meat by negative ions works while the oxidation-reduction slows the spoilage of dry aging meat long past the normal aging period making it possible to increase the amino acids that promote the fermentation conditions by leading enzyme.
