Insulation of walls with his own hands - turn-based technology

heat loss through the walls of the house can reach 30% of total heat loss, so one of the main stages of building insulation is the insulation of the walls.As the insulation for the walls is often chosen mineral wool.Mineral wool is manufactured from molten glass, slag or rock, a resin used as a binder.The material has a fibrous structure and, depending on the application, the fiber direction may vary.

outside Wall insulation mineral wool has a number of advantages:

• It is relatively cheap insulation with low thermal conductivity;
• Mineral insulation has good sound-absorbing properties;
• Mineral wool does not support combustion, so it can be used for thermal insulation legkosgoraemyh structures;
• This material is permeable to water vapor and does not create the effect of a thermos, the building "breathes";
• mineral wool is easy to install - the insulation is sold in the form of mats or rolls, you can choose the most convenient option;
• Depending on local conditions, you can choose the correct thickness of insulation;

Mineral wool does not rot, are not susceptible to defeat by a fungus, microbes and rodents.

Disadvantages mineral wool refers deterioration of its insulating characteristics when wet, so it must be protected from atmospheric moisture and condensation.In terms of environmental mineral heater, operated under normal conditions, it does not pose any danger, since the release of harmful components occurs only when heated mineral wool up to 300 degrees or more.

Choosing insulation thickness is carried out with the help of heat engineering calculation, while taking into account the thermal conductivity of the wall material, its thickness, as well as normativnoeteplosoprotivleniesten for a specific region.You can use a table to simplify the calculations.

technology insulation of walls with mineral wool

1. Preparing walls for installation of insulation depends on the material from which they are built.Wooden walls need to be impregnated with an antiseptic, to avoid the danger log mikroorganizmami.Uchastki damaged by rot, fungus, mold should be thoroughly cleaned and soak appropriate solutions - after laying insulation access to them will be impossible.Brick walls and foam free enough from flaking plaster, paint.If the walls are damp - they must be thoroughly dried.Casings and window slopes need to dismantle and remove from the walls of the fastening and decorative elements that can damage the vapor barrier and insulation.
2. Under mineral heater put a layer of vapor-permeable membrany.Plenku arranged so that the vapor permeable side facing the wall of the house, and smooth - to uteplitelyu.Paropronitsaemaya diaphragm is necessary in order to ensure the removal of water vapor from the walls of the house through the insulation.On the smooth wall is allowed to lay the mineral insulation without first laying a membrane film.

3. vapor-permeable film is attached on top of the guide rails of wood, or a profile for fixing plasterboard.To attach to the wall of screws or by means of mounting a pair of dowel-nail.The distance between the strips is chosen so that it is 1-2 cm less than the width of the insulation.The thickness of the strips should be equal to the thickness of the insulation.Fixing rails are starting from the corner of the house.When mounting rails use level.If the wall is uneven, to secure the frame can be used for perforated hangers gipsokartona.Esli use a heater in the form of mats, you can further secure the bottom edge of the horizontal wall rail, which will lower Insulating mat set.

4. insulation mats or web material is placed in the space between the guide rails, thus laying the mats start from the bottom and roll materials - top, fixing heater on the wall or vraspor between the rails,or using multiple anchors with hat wide.MDF material for brick or block walls are fixed on a special adhesive that provides a snug fit insulation.Between the insulation and directing at the same time there should be no gaps.First, fix whole pieces of insulation, then fill in the remaining areas around window and door openings.

5. top of the mineral insulation is put another layer of the film - windscreen and waterproofing.The film should also be vapor permeable to moisture freely assigned from the layer of insulation to the outside.The film is attached to the rails brackets without tension, after which further reinforce the entire layer of insulation and a vapor barrier to the wall using dowels with a big hat, fixing points for the best waterproofing glue can be metallized tape.

6. important step insulation of walls is a device ventilated facade.Ventilation clearance should not be less than 5-6 cm, for this guide over stuffed or attach additional counter-profiles, which are mounted on a ventilated facade siding, block-house, or other finishing materials.

7. With insulation of walls outside the thickness increases, therefore it is necessary to establish new window soffits, window sills and trim and trim elements.It is better to buy them immediately when buying a ventilated facade.

outside Wall insulation mineral wool is one of the most popular ways of building insulation.The popularity is due to the low thermal conductivity of mineral wool, so most of the heat remains inside the building, as well as environmentally friendly material, its ability to remove moisture from inside the house.In addition, mineral wool is an excellent soundproofing.

for insulation of walls and use other materials, such as foam or extruded polystyrene.These methods are used under the plaster finish, as the slab insulation is an excellent basis for a plaster.
