Thermal insulation of concrete floor with his hands - the instruction

for insulation of concrete floor, you can use simple and proven solution - to construct the floors on joists.This design is extremely popular because of its simplicity and reliability.

algorithm insulation of concrete floors at the device of wooden floors on joists.Please note that in between the joists and the walls of the room is placed a layer of insulation material.This is a necessary step in the insulation of concrete floor, as it prevents the formation of so-called "cold bridges", that is, those areas where negative temperatures on the street will enter the room.Their thickness should be about two centimeters.

Here the band presented a close-up.Note that their installation also contributes to soundproofing the premises.

insulation edges

After that, the pre-aligned rough draft box placed logs - wooden beams, which will serve as stiffeners for the sub-floor, as well as separators for strips insulation material.

Logs stacked against the wall and then parallel to each other at a distance of about 90 centimeters.

laying Sample lags

Directly under the logs, you can also arrange a thin layer of thermal and sound insulation.This will help create a more comfortable atmosphere in your room.

Laying the lag in parallel to each other

laying lags in parallel to each other

If under your insulated concrete floor is unheated room or ground, the thickness of the insulation layer should not be less than 5 centimeters.If your concrete floor is over heated premises, the thickness of the insulation layer can be reduced to 3 centimeters.

laying insulation material between the lags

between wooden joists are placed pre-cut plates insulation material.

Laying insulation boards

That's the way a room looks with a fully stacked insulation boards:

These boards are stacked close to each other, they are extremely easy to installation.

Laying insulation boards all over the floor

The next step in the logs are stacked so-called "distribution board" or rough floor, which should evenly distribute the load to the finish flooring on solid logs.As a sub-floor material can be used chipboard or special durable drywall.

floor mounting lags

Notice that the seams of distribution boards are located directly above the bars lag.Distribution boards are fastened to the joists with screws, self-tapping screws.

Fixing the floor using screws

then in some cases requires support installation.It is strongly recommended that the substrate laying under the floorboard or laminate, otherwise this floor finish is too "loud."

Puts substrate under a laminate

Then you can proceed to the laying of laminate or wood flooring.

Thermal insulation of concrete floor on the balcony

Another commonly used method is the thermal insulation of concrete floor insulation balcony or loggia.

As in the previous example, we start the process of warming with laying on the floor lined wooden beams.They cut to the width of the balcony and placed on the floor.

Puts logs on

balcony distance between stacked parallel bars should be about 40-60 centimeters.

distance between the lags of 40-60 mm

To fix the wooden beams on the floor use frame anchor.

Frame anchor for attaching beams

nasverlivaem Pre-drill the wooden beam on three-quarters of the depth.

nasverlivaniya Once all the boards are changing to drill and hammer drill are drilling concrete.The depth of the drilled hole should exceed the length of the bolt by about 3 centimeters.

not seek at this stage to achieve a perfectly flat surface, we will do this later.

After fixing the boards to carry out repeated vacuuming the room.

clean the room

At fixed cross laid rails.They should be chosen with as much as possible the correct geometrical shape.The distance between the rails should not exceed 45 centimeters.

Puts rails

With the building level is determined by which of the longitudinal beams are higher.In our case - it is left from the master.

Determine the building via the upper level bar

Determine the level of the top construction using timber

Then use that same level determines which of the longitudinal edges of the timber we will raise.Fix the highest part of the longitudinal beam self-tapping screws.

Fix the screw timber (softwood)

Then, using the building wedges, puts on both sides - all aligned in the horizontal rails.

aligned horizontally all rails

first extreme aligned bars - and then use a long level - the average timber.

First, line the side rails , and then middle bar

Cover the resulting sub-floor structure - it can be used chipboard sheets.Fix chipboard to the beam is possible by means of screws.Do not forget to mark on the wall of the central line of bars not to miss when tightening the screws.

Puts subfloor

little trick - when tightening screws you need to be positioned so that your weight is on the joists, beams, lying under the sub-floor.The very rough floor should sag between joists under the weight of 70 kilograms of approximately 2-3 millimeters.This ensures natural ventilation of the space under the floor.
