How to insulate a loggia with their hands

insulate a loggia is much easier than a balcony, and if you plan to use it not only for the storage of all that does not fit in the apartment, but also as another cozy room, the warming - it is a necessity.It is not only significantly reduce heat loss, but also prevents the penetration of street noise, dust and harmful gases.

Before proceeding to the most warming, should undertake a number of preparatory activities.

Step 1: Prepare the parapet

Parapet - is outside the fence, which is the most vulnerable place of construction.Parapet in direct contact with the street and in most cases is the M / B plate.Before warming parapet need to close up the gap - for example, lay a brick it (be enough and masonry in ½ brick, so as not to burden the overlap).

Preparation of the parapet

Preparation parapet

If metal parapet, and its level is not the same as the upper ceiling, the first clutch is carried out this element and the side walls.It is advisable to use this concrete blocks, although it is quite suitable and ceramic brick.The outer surface is finished with siding, which is also a little warm a loggia.

Note!All elements of the wood should be treated with an antiseptic to prevent bacteria and, as a consequence of rotting material.

Step 2. Glazing

loggia First must glaze.It is desirable to establish plastic windows and the installation of trust experienced specialists.Packages must have at least two chambers, glass thickness (total) must be at least 3.2 cm. With proper installation of glazing on all sides will be surrounded by a special expansion profile.

After installation, all the joints are filled with foam (the latter is necessary to lay evenly, without gaps and differences).After that, the outside is masked nashchelnikami foam to protect against UV rays.

Note!Sometimes at this stage and installed the heater.In fact, this makes no sense, because without competent insulation all design elements in it the temperature is only two or three degrees higher than outside.

Step 3. Preparation of all necessary

for warming loggia need the following materials:

  • insulation (preferably foam);
  • wooden slats 2x5, 3x5, or 2h4,5 3h4,5 cm;
  • foam;
  • galvanized hangers;
  • steam;
  • guides;
  • dowels made of plastic;
  • timber joists on 5x7 cm;
  • reinforced with adhesive tape;
  • antiseptic.

also need a variety of tools:

  • punch;
  • gun foam;
  • building level;
  • electric jigsaw;
  • level;
  • pliers;
  • metal scissors;
  • screwdriver;
  • roulette;
  • marker.

How to insulate a loggia with their hands

Upon completion of the preparatory work can proceed directly to the insulation.You should start with the ceiling.

Phase 1. Warming ceiling

Step 1. First, the ceiling hangers attach needed for further fixing rails.



Step 2. The foam slabs doing slots for hangers.

Step 3. plates are fixed by means of foam or dowels made of plastic.

Note!Core diameter dowels selected depending on the total weight of the insulation.

Step 4. All holes are filled with foam.

Step 2. Insulation floor

Step 1. First of all, on the floor of the timber stacked pads, pre-treated with antiseptic - they serve as a support for the structure.



Note!When installing the gasket should be checked periodically for building level horizontal.

also need to make sure that the crate does not protrude above the layer of insulation to a maximum of 5 mm.

Step 2. means of screws to the supports are fixed joists.In the last placed insulation boards.

Step 3. laid a layer of vapor barrier (foil upwards).



At the same time in the outer corners of the material should be no joints, otherwise inevitably formed thermal bridges, as they are called.By the way, the cause of such bridges may also be:

  • metal frame fixed to the plates themselves;
  • wooden joists, installed the same way.

Step 4. All joints are glued mounting tape to achieve a "thermos effect".

On the floor is finished, you can move on.

Step 3. Thermal insulation of walls

determined the need for insulation in the walls of the structure.The front wall and the corners that are adjacent to it, are in need of a thorough insulation.Next designated height dobornyh expanders.

Insulation walls

As the insulation is desirable to use foam boards with a selected quarter, which prevents the formation of pinholes in the joints.If these plates could not be found, then undertake regular and stacked in two layers.Thus seams should shift to avoid the appearance of through holes.The first layer is fixed to the overlying plate with plastic dowels.The following can be mounted on the ground using the mounting foam.


rails under the plate heater

So, need insulation:

  • side walls bordering the street;
  • angles of the walls, which are adjacent to other spaces;
  • walls in contact with the other balconies.

Under glazing and along fixed vertical strip of insulation on the side and front walls.At the height of the strip must be equal to the side walls and the width:

  • in a brick building - not less than 50 cm;
  • in the panel house -. At least 30 cm

To fix, you can use all the same assembly foam.In the corners of the thermal insulation is placed a layer of 2-3 cm, and then covered with foil vapor barrier as well as for floor insulation.

Note!To heighten the effect of vapor barrier is attached to the "warm" side of the insulation.

inner wall balconies with their hands With suspensions, pre-installed on the wall, fasten the rails.This is to ensure that between the insulation and finishing material formed air "cushion".Typically, if you plan to install dryer, curtains and light fixtures, the guide for them to install it at this stage of the work.

blocks as the guide can be used as the galvanized metal profile and an ordinary wooden beam (covered with antiseptic, of course).

Step 4. Finishing

After installing the heater can only give a finished look loggia, that is to decorate the walls.



Step 1. Initially, all the surfaces are covered crate of timber 2x4 cm. Mounting beam is made directly to the ground with dowels or screws.Horizontal position is controlled building level.

Step 2. attached to the crate finishing material.In most cases the use of drywall or plastic panels, t. To. They are characterized by high resistance to moisture.Thus it is better to choose the second option, because the drywall needs to be time-consuming follow-up work - primer, putty and finishing topcoat.

Step 3. Under the windows that overlook the loggia of the adjacent room, set window sills of plastic.Under the door is fixed threshold of PVC.Characteristically, under the threshold should be set in advance a single lag treated with antiseptic.



Step 5. Conduct heat

It is worth remembering that a thermal insulation material to insulate a loggia impossible.Whatever may be the airtight construction, heat it will not appear if it is to not fail.Since the state standards prohibited water heating supply to the loggia, an excellent option is the heat convector.If the loggia area greater than 6 m², you can put just two on opposite sides of the convector.In addition, you can install an electric fireplace or portable oil heater.

Electric convector on

balcony more effective, but at the same time, more labor-intensive option - installation of electric underfloor heating.To do this at the stage of foam insulation on top of the cable should be laid for underfloor heating, bent so that the maximum area was covered loggia.Then all this is covered with a concrete screed thickness of 45-50 mm.

To prepare the solution required:

  • cement "four" brand;
  • water;
  • sand (mixed with cement in the ratio of 5: 1).

When the screed has dried, it is placed on top of the tiles.

How much will my insulation loggia

study the technology of warming, one may wonder how much it will cost.At first glance, everything is quite expensive:

  • 8000 rubles for construction materials (for loggia 3 m²);
  • of 11 000 rubles - eyeliner electricity and underfloor heating systems;
  • another 7 000-8 000, if desired glazing.

The result - 30 000 rubles.But it is worth considering that the materials of the European manufacturers of higher quality, and therefore expensive.

If we look at the insulation as an attachment for many years, the cost of a few years it seems not so high, because overdoing with savings have to redo everything again.

Common Mistakes

Wall insulation from the inside - a very important process that has no right to make mistakes

Wall insulation from the inside - a very important process that has no right to make mistakes

If insulation was carried out incorrectly, the condensate is formed on the walls of the loggia (the so-called effect of "weepingwalls ").The reason is simple enough: in contact with the cold wall of the warm air condenses.If moisture builds up too much, the insulating material will start to lose their properties, and the fungus appears on the surface, gradually destroying the structure.

If loggia periodically occurs, all the seams between the panels must be carefully sealed.

In conclusion

to convert balconies into a full living room need a lot of effort, time and money.But it is much better to spend a couple of months to repair than for decades to complain of "chaos" in the loggia.More details about the warming of the technology can be found in the video below.
