So whether you need to warm a loggia?

Of course, it all depends on the individualpreferences. If you are determined to use the loggia only as a warehouse, then it is not necessary to insulate. But in order to bring to life one of the most interesting design projects, where there is a huge amount, insulation - it is a necessity. In addition, it will reduce heat loss and significantly reduces the penetration of dust, noise and harmful gases into the room, which is especially important for people living in apartments with windows facing the main streets and avenues with heavy traffic.

Windows on the balcony

Installing double-glazed windows will reduce noise and dust penetrating the street

On the balconies you can arrange a small greenhouse, set the coffee table and armchairs, to arrange a sports area with exercise equipment and a lot more interesting. In this case, warming again to avoid.

It is also necessary to warm the surface of the loggia inif you decide to combine it with the adjacent room, because otherwise the outer wall in the cold season will syret and covered with mold, and the room will be a very low temperature.

Meticulously preparing for warming

Parapet, or an external enclosure loggia - isthe weakest link at warming. Indeed, it is in contact with the street light is designed to pass while removing noise penetration of moisture, dust and cold. The most common is the parapet concrete slab, in this case, before the warm loggia with your hands, you need to carefully lay wide slit (eg brick) and concreted narrow.

Parapet loggia

For masonry parapet balconies enough in a half-brick, so as not to burden the design of obesity

If parapet metal or is notIt coincides with the upper level floors before insulation loggia necessary to carry out masonry parapet and side walls. For this purpose, better to use concrete blocks or ceramic brick. The outer surface of the enclosure can be finished plastic siding or decorative panels, it also warms the area of ​​loggias.

Tip: all wooden parts should be treated by any antiseptic preparation in order to prevent the emergence of bacteria that lead to destruction and decay.

Glazing - a mandatory step

Before starting insulation loggia necessaryglaze. This will require the kind of plastic construction, the installation of which should be entrusted to specially trained people. For glazing balconies are best suited triple-pane glass packages with not less than 32 mm thick. With proper insulation of the installation must be accompanied by the installation of expansion profiles dobornyh left, top and right side of the double-glazed windows.

After installation, you should carefully zapenit seams andjoints with foam, which should lie flat, without defects and cracks. Further special foam nashchelnikami locked from the outside - it will help protect it from the harmful effects of sunlight.

After you install double-glazed windows all cracks should be carefully zapenit

In some cases, owners of apartmentsstop at this point and set the heating device. As a rule, it does not make any sense, because without proper insulation parapet walls, ceiling and floor in the loggia temperature is only a few degrees above the outside.

What is needed for insulation

To carry out work on warming loggia need:

  1. Insulated material, is commonly used foam Extrol or TECHNOPLEX.
  2. Polyurethane foam and cleaner for it.
  3. Vapour material (penofol or izolon).
  4. Plastic plate type dowels, plugs in the form of a plastic cork plugs nailing, screws for fastening the pads to the joists and the concrete slab for the hangers, nails.
  5. Metallized adhesive tape.
  6. Antiseptic coating lag.
  7. Bruce on the joists and backing for them to raise the level of the floor surface (chamber drying 45x60 or 50x70 antiseptic).
  8. The guide for attaching decorative materials inside the loggia.
  9. Galvanized profile and crabs for installation.
  10. Galvanized hangers for mounting rails and profile.
  11. Wooden beams 50h20, 50x30, 45h20 or 45h30.
  12. Tools (hammer, screwdriver, pliers, metal scissors, tape measure, level, pencil, level with tripod, jigsaw and gun foam).

How to insulate yourself loggia

Construction of thermal insulation system on the ceiling

Go to ceiling insulation loggias. To do this, suspensions attached to the ceiling for the subsequent installation guide. Now polystyrene plate is fixed to the ceiling surface mounting or mounting on foam plastic dowels Belleville, after making a small slit in the insulation for hanger.

Tip: core plugs (plastic or metal) should choose based on the weight utelitelya.

The holes are sealed necessarily pieces of insulation and assembly foam.

Warming of the floor in the loggia

So, how to insulate the floor on the balcony? First, a base plate fastened gaskets treated with antiseptic timber serving as supports.

Important: laying-support should be aligned on the level.

Installation should ensure thatheight of timber logs with the thickness was such that they towered above all the layers of insulation not less than 5 mm. Logs are attached to the supports with screws and plates are arranged between the insulation material. Further stretches out vapor barrier foil. This must be done so that the joints of the vapor barrier layer was not in the outer corners, only in this case you can avoid "cold bridges".

Placing insulation on the floor loggia

Placing insulation on the floor loggia: laying timber and the location of mineral wool between joists

Important: the formation of thermal bridges causes also the installation of wooden log in the thick expanded polystyrene plates, and the use of a metal frame, mounted in the body panels.

All the connections you need to glue foil layer tape to secure the thermos effect. If the result is a loggia with a combined living room, then insulation and floor finishes carried to a height of the inner walls of the plane. At the same floor level becomes higher due to a heater, placed between the joists.

Wall insulation: Run rules

The first stage should determine whetherin wall insulation loggia. The walls that border the street, as well as the adjacent corners of the walls bordering the bathroom, should be thoroughly warmed. Next, determine the height dobornyh expanders. To make better use of thermal insulation polystyrene plates with the selected quarter. This allows you to get rid of through holes in the places of their connection. If these plates was not available, then the common plate to be laid in two layers with an offset connection joints so that the through holes were not formed. The first layer of the insulation material is attached to the ceiling plate using dowels Belleville, and the second can be attached to the first component foam.

Wall insulation from inside the lodge

Wall insulation from inside the lodge

So, insulate exterior walls by fiberglass; side walls bordering the street, as well as with neighboring cold loggias; vertical angles of the walls adjacent to the living quarters.

Along plastic constructions beneath and to the side wall and along the warm parapet is necessary to attach a vertical insulated material strip height equal to the height of the side wall, and a width:

  • for panel houses - more than 300 mm;
  • for brick - more than 500 mm.

This can be done with the help of foam. Angles insulated insulation layer is 20-30 mm, and it is located on top of foil vapor barrier foil inside the loggia.

Laying the vapor barrier wall

Above the insulation should be attached foil vapor barrier

Tip: For best results, steam installed on the warm side of insulation materials.

On top of the vapor barrier using suspensions, advanceattached to the walls and ceiling, set at the level of the guide, so as to form an air gap between the insulating layer and the finishing material.

Mounting rails on the walls of the loggia

Mounting rails on the walls of the loggia

Tip: At this stage you need to install guides to the lamps, curtains, dryer and other equipment.

Important: Before installing the rails on the outside wall of the house is necessary to carry out electrical work.

The guide can be installed from a wooden beam or galvanized profile.

Finishing works: the creation of design

The question is, how to insulate a loggia, almostresolved, it remains to give the room a finished look cozy. On all surfaces applied to a dry timber crate 40h20 mm, treated with antiseptic. Crate is exposed through the levels, is mounted on the anchors and screws directly to the concrete.

Finishing materials are attached to the crate. Most often used for interior trim loggias used plastic panels or gypsum board, which has high moisture resistance. The downside of the application of gypsum panels is a need for large-scale follow-up work. Plasterboard require primer, putty and paint or stickers wallpaper.

Loggia after finishing

Loggia after the finish: a cozy resting place with unique decor

Under the windows of the room overlooking the loggia,install plastic window sills and under the door - PVC threshold under which you first need to install additional lag wood treated with a special antiseptic solution.

Conducting heat to the loggia

To the loggia it was not cold,need extra heat sources. State Standards is strictly forbidden to carry out to the loggia water heating, so the best option would convectors. If floor space is more than 6 squares, then install the heater need two at opposite ends. You can use the mobile oil heaters and electric fireplaces.

Possible errors and some hints at warming loggia

Incorrect work on warming maycause condensation on the walls (the effect of "weeping" wall) between the insulation and the wall. This phenomenon has a very simple explanation: the warm room air condenses on contact with the cold wall, overlooking the street. A large accumulation of moisture in the insulation layer is fraught with a significant decrease in heat-insulating properties of the material and the appearance of mold on the walls, destroying the building.

If on the balcony from time to time there are leaks, to seal all joints bulkhead.
Better insulation works loggia trust these professionals, this will avoid unnecessary costs, both financial and time.
