How to avoid condensation under the floor?
Revision 1
Condensation has formed under the floor. The structure is as follows: Strip foundation 60 centimeters above the floor (underneath sand), Beams (150x100) on the foundation, the beams laid insulator Paroc, under the beams punched a bar 50x50, which is also laid insulator to the total thickness of insulation to 20 cm, then Ondutis SA 115 wind moisture barrier and lath-inch to lie on top of the insulation.
As a result, the water is located in large drops on the entire windbreak. The insulation is dry at the same time (the wind barrier keeps water out).
The air holes are made in the foundation (110mm, 4 pieces for each part of the house 8 to 4 meters), and near the air holes foil is dry, but literally in a radius of 1 meter.
Now I force a fan near one of the vents to let fresh air into the house. But that's not the solution. How do you deal with condensation?
