the floor boards on joists is most commonly used method in this type of finishes. Best if the boards are attached to the so-called. tongue and groove, but it can also be mounted in combination wręgowych simple.
joists are made from wood of coniferous trees and logs, patches, and squared. The minimum width of the joist should be 50 mm and the thickness should be at least 1 - 2 cm greater than the thickness of insulation provided. Spacing between them adapt to the material used for insulation, however, can not be greater than approximately 59 cm in light between them. Steel joists and fastened with screws galvanized steel, or ordinary plugs. Length of the joists should be less about 4 cm from the total distance between walls. Joists before laying shall be protected from all sides with a fungicide. From the szlichty should be secured and additional sound insulation-proof. For this purpose the strips of felt attached to the joists (as acoustic insulation) and strips of rubber (as a damp proof membrane).
flooring on joists due to the application area can be divided: 1st
For wooden floors
second The half-timbered houses,
third On the fourth floors of reinforced concrete
Directly on the ground
The wooden floors
Boards can be attached directly to the beams, (mainly nieużytkowych attics or on joists laid across the beams.
The half-timbered houses
on concrete floors
joists are placed directly on the backing equalizing. Where the floor is the unheated space should be used in addition, under the joists damp insulation in the form of strips of foil or tar paper.
directly on the ground
In this embodiment the joists must be at least 10 - 12 cm in order to solve between them, damp proof and heat and ventilation place for all.
Beliz conquered slats or wire mesh mounted on concrete pillars, covered with asphalt. Slats or mesh are used to attach to their thermal insulation. Then, the thus prepared substrate is fixed the insulating film which is followed by nailed to joists.
