K family'  house

1. N family' house / Osaka Prefecture, Osaka city / Roof

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.
