If you are planning to install insulation or its thickness equal to 5 cm, it is possible to dispense with retaining bars and to lay the joists directly onto the roofing material.
4. After installation of the retaining bars start lag. Logs stacked reproach the direction of light from Windows at a distance of 350-500 mm from each other. The thinner floor Board, the less distance between the joists.
5. It is very important to align the joists horizontally, depends on the correct installation of all floor. The first lag puts from the highest point of the subfloor. Then, at a distance slightly less than the length of the level place the second lag and align them horizontally. To adjust the horizontal, you can use the lining of the roofing material.
