Rough floor in a wooden house .Installation of the subfloor

Installation subfloor on joists

Often in the wooden house as a material for the sub-floor joists selected from the wooden beams.When installing such a framework is necessary to ensure that the logs do not touch the walls.It is necessary to observe a distance of 3 cm between the end of the joists and the wall.This slot is needed to fill its soundproofed.
Among the advantages of this type of installation sub-floor - small costs and speed the process of laying.However, it has a clear disadvantage caused by the mounting rigidity, - a low level of sound insulation.

lag Preparing for rough sex

As the lag can be used different kinds of wood.You can even use a third grade wood, although such material needs to be improved.It is necessary with an ax to level the surface of the wooden log to later put under a perfect horizontal.They were then coated with an antiseptic solution.There are two ways to mount the wooden log: on the ground and in the overlap.

Mounting lag for the sub-floor to the base

With this method of installation must be cut loose topsoil, razravnyat it and then fill up with gravel.After ramming material is marking the area to which you plan to install lag.Do not place logs in the rubble, it is necessary to prepare the support, for example, wrapped with roofing material grillage.

supporting columns set only on the foundation.To do this, on the lines of the future lags dig holes with the same spacing.Then pour in the bottom of the gravel and sand, tamping each layer.At the bottom of the need to lay out a grid of rebar.Pit then poured cement slurry comprising water, sand and cement.After a set of post-foundation under a log and put the waterproofing layer.

The next phase - installation of the lag.Their fixed to the post through corners, dyupeley and screws.

Installation lag for sub-floor for recoating

This method is good for the long lag mounting.To fix the lag in the bottom plate walls are made grooves with depth equal to the width of the boards.At the ends of the timber are put on rubber gaskets for damping noise, after which they are placed in the grooves smoothly.Since one can not keep the grooves beam must be used to support this goal.For this option, the installation log for black floor suit quite brick pillars.They are installed on the same principle as the wooden base.That's only necessary to build a brick pillar.

To determine the distance between the two logs, you need to know what the board will be applied to the upper deck.Step stacking logs decreases with decreasing thickness of the board.Do not ever forget the laying of waterproofing material.

Steps for installing subfloor

After lag mounting, as a rule, it is in the process of laying different layers of sub-floor, comprising the steps of:

1. Fix the cranial bars having a small cross section, the bottom of the logand side.If you could not get these bars instead of them can take the boards, the width is greater than the joists 4 cm. Boards nailed in the likeness of the boards.
2. On cranial bars stacked boards.Their goal - to keep the insulation, so they do not need fixing.
3. above stack waterproofing material in such a way that it covers the walls of the floor, and the boards and joists.Suitable for waterproofing of the film.
4. between joists is essential to put a heater.The possibility of inserting two layers penofol - material with a high heat reflecting ability.

   

5. laid a layer of vapor barrier wall by covering the floor.For its fastening use a stapler.
6. creates a ventilation gap, which is nailed along the counter-lag.This is done to provide a vapor barrier.
7. Stack wooden flooring.As a material for finishing laying subfloors can be used chipboard sheets, boards.As well as logs, boards do not lay flush with the wall.
8. To achieve the sound insulation is mounted DSP boards.

Installation of concrete subfloor

concrete sub-floor base is most common in the apartments, but many prefer the rough concrete floor in wooden houses.Installation blister bases in the first step is to provide a waterproofing and thermal insulation, as well as during installation on the sub-floor beams.

Before pouring the floor, you need to take care of the preparation of the guide, which is secured on a level to achieve a smooth surface the concrete subfloor.For the filling you can use betonokeramzitom and can be traditionally - plain concrete.The first material is most advantageous in view of its noise insulation qualities.After pouring the floor we begin to flatten it and wait until it dries.And then enjoy the result.
