Watch the video It consists in the granular cork blowing in the empty cavities of the perimeter walls of the buildings. It can be done from inside or outside the building. The cork size 3 / 8mm is the most used for 4 / 15cm cavities. For small cavities up to 3 / 4cm we recommend the use of 1 / 3mm dim grain. For large cavities and if you have a suitable tool you can also blow the size 3 / 14mm.

To calculate the necessary cork multiply the square meters of the wall by the width of the cavity, the granular cork is packed in bags of 125 lt equal to 1/8 of mc.
