Warming of the wooden house from the outside

Wooden houses are traditional for Russian cities and villages - they reliably serve its owners for mnogu decades and even a century of often step over the line.But sooner or later there comes a time when the warming of the wooden house from the outside becomes a necessary exercise because, while under the influence of wind, moisture and UV rays, parts of walls to crack and covered with cracks through which the room gets cold easily.In order to reduce heating costs, you need to invest money to wall insulation, and it will pay off in the first winter.

After outer insulation, a homeowner decides to just three issues - make warm house, reduce the penetration of street noise in the room and update the external Diza dH Article swarming.

But before buying the stuff and get to work, you need to learn, how modern heaters better suitable for wooden buildings, and a sequences necessary to carry out its installation.

To date, the most popula

r materials for the thermal insulation of wooden buildings from the outside is in polystyrene and mineral wool panels of different types, manufactured in the form of mats or rolls.But apart from them, are increasingly used sprayed insulation compounds such as Penoizol or ecowool , and thermal panels in recent years, which include not only the warming layer, but also the decoration.

Styrofoam - is the most affordable material for insulation.It has good performance, gives the opportunity to substantial savings on heating.

Standard panels of expanded polystyrene

standard polystyrene panel

Produce polystyrene foam panels of various thicknesses, of 1 × 1 and 1 × 0, 5m , density from 15 to 40 kg / m³.For insulating external works are commonly used material average density - about 25kg / m³ and 50 mm thick.We must remember, the higher the density of the insulation, the lower the thermal insulation quality, but higher resistance to corrosion.Therefore, high density expanded polystyrene is used mainly for thermal insulation of the floor.

Styrofoam easy , as it consists of a mass of foam filled with air, so that it becomes a good barrier for the cold, and sound waves.Expanded polystyrene has a low thermal conductivity and therefore ensures long preservation of the accumulated heat in the room.

It is easy to cut and attach to the wall.It is resistant to temperature changes and UV radiation, as well as almost does not absorb moisture, so it is quite a long period of operation.

But, in addition to numerous advantages, have expanded polystyrene and their significant drawbacks:

  • low mechanical strength - enough material breaks down and crumbles easily, so after mounting on the wall it will require protection through mesh reinforcement and decorative coatings;
  • usual Styrofoam can not be called a non-flammable, and at high temperatures it becomes a fluid mass burning and emits hazardous to the human body substances.Non-flammable, and more precisely , self-extinguishing extruded polystyrene is considered only, and it is recommended that it be used for thermal insulation of wooden buildings.
  • if you plan to mount the plate with an adhesive, it is necessary to know in advance whether it is suitable for use with polystyrene, as some substances destroy this stuff.

Mounting foam polystyrene insulation

panels are fixed to the surface in two ways - on crate or directly on a plane wall with glue and krepleniy- "umbrellas" ( "fungus").Selecting technique depends on the surface on which it is mounted.

If house built of timber and its walls have a smooth surface, you can use both, but it's easier to do the adhesive.

  • before installing the insulation, the surface should be inspected for cracks and fissures.If these are found, they must be repaired.The process can be carried out in various ways - is caulk cracks tow, treated with lime and embedding with modern materials such as sealant or foam construction.
  • Then a wooden surface it is necessary to process antiseptic - he will protect her from pests and formation of moss or mold spots.
  • When the antiseptic to dry, you can begin the installation of insulation.For it is well stuck to the wall, on its surface can be lightly brushed to walk rail .
  • installation of insulation starts at the bottom corner of the wall.For the convenience of fixing and evenness of the first row of panels is recommended at this point to establish a special profile.It should have a width corresponding to the thickness of the material.
For ease of installation of the lower row , it is possible to set the metal profile

For ease of installation the bottom row, you can install a metal profile

  • plates are coated with a solution of a special construction glue dot and on the edge, and then applied and pressed against the wall.They must be held tightly to each other, creating a single surface.If the gap between the panels were formed, their after drying glue and secure to the wall must be sealed with foam.

  • After removing first series, the following rows are mounted on the system of masonry, in dressing .
  • waited 3 - 4 days after the plates mounted to the wall, they must be secured with the help of krepleniy- "fungi".Each plate must be secured 5 - 6 similar elements.Fastening legs should have a length several centimeters larger than the thickness of insulation, for example, if the insulation thickness of 50 mm, the "mushroom" from the leg must be chosen 100 mm.When driven, hat should enter in the styrofoam slab flush with its surface.

  • When all the insulation is installed, you can begin to Styrofoam reinforcement - this is done using a fiberglass mesh-serpyanku.

  • on the remaining surface is fixed wide grid, which is implemented in rolls.Her laid with overlapping 70 - 100 mm as the adhesive mass.Serpyanku should like to drown himself in the adhesive.Securing it on the surface of polystyrene, and lies on the trowel from the center to the edges - the system « herringbone », removing the excess glue.
  • When the adhesive on the reinforcing layer dries, the wall should be covered with a mixture of primer - on her well lie decorative plaster. siding or battens fix is ​​simply not on that -

In this case, only the decorative plaster can be done finish.But on the plastered walls can be fixed easy finishing material, such as plastic tiles under brick or stone.

Since the installation work the second embodiment (for crate ) are conducted in the same manner as in the mineral wool insulation, they will be examined below.

Mineral wool

Mineral wool - is not a new heating material, it is the test of time, as applied for decades, and during this period did not lost its popularity.

One of the best insulation - mineral wool

One of the best insulation - mineral wool

Mineral wool consists of numerous fibers, bonded together by special structures.Produced three different types of mineral wool , and they differ in the base material manufacturing - is rock wool, glass wool and slag wool.

Of course, there are also other differences - this moisture resistance, thermal conductivity, resistance to some external effects, as well as the thickness and length of the fibers.Slag

The material made from blast furnace slags, which, after processing in the stretched fiber length of 10 to 20 mm and a thickness of 10 microns.

choosing insulation for the façade of this option should be discarded immediately, as it is hygroscopic.Contact with moisture it may cause material within the mold.In addition, if it is located near the metal profile, the oxidation reaction can occur, as in the slag are its composition residual acidity.

From the use of glass wool for insulating the outside walls should be abandoned

From using slag wool to insulate the walls from the outside should be abandoned

Slag has a high thermal conductivity for heat insulation, and this characteristic is also not well suited for thermal insulation of walls of private housing.


glass wool made by melting glass, the length of the fiber material from 15 to 45 mm, and thickness - no more than 12 - 15 microns.This insulation is well suited to protect the walls from the cold outside - glass wool heat-resistant and non-hygroscopic.In addition, it has a small weight and good elasticity.Made in wool mats or rolls, and thanks to its flexible packaging are not excessively large volumes , since the material is easily compacted.

Glass wool, manufactured in mats - more dense and durable.It not only warms the walls well, but also provides excellent protection from the wind, and, in addition, it much easier to establish between the bars crates .

Glass wool -good insulation , but it requires special care when working with it

Fiberglass-good insulation, but requires special care when working with it

Lack - at its installation must be carefully protect the eyes, face and hands, respiratory organs, as thin glass fibers in contactthe fabric may hurt them or cause severe irritation.Therefore , working with this material, you need to wear a respirator, goggles, gloves and protective clothing.

Stone wool

Basalt stone rocks are raw material for the manufacture of stone wool.It is the same as other types of insulation, composed of fibers, has low thermal conductivity and high hydrophobicity , and also ability to withstand high temperatures, so it may be called heat-resistant material.This kind of wool is not so elastic, therefore its shape and volume stable enough.Thanks all its positive features, it is perfect for the insulation of facades.

Basalt ( stone ) wool - a material with virtually no drawbacks

basalt (rock) wool - a material with virtually no drawbacks

Stone wool is produced in the form of rolls or plates, can be more dense and soft, but the wall is necessary to choose the most dense material.

This heater is not dusty and does not irritate the skin, and it can even work without protective devices.

All of the above types of mineral wool have a classification by stiffness .This indicator must be clarified, as not all brands are suitable for thermal insulation of facades.For such work is necessary to choose the material of the brand of RV-175 - a tough stove, or LVP -200, which means increased stiffness plate.

Thermal insulation of walls with mineral wool

  • Installation insulating layer of mineral wool made with crate , mounted on the wall - this method can also be used for thermal insulation of expanded polystyrene.It is suitable for both flat and for the log surface.
  • In this case, the wall mounted crate of timber or metal profiles, galvanized, and between which is fixed slab or roll insulation.

  • In order to achieve the best effect of warming and keep the walls safe from moisture, advised by crate pre-fix vapor barrier material.
  • must be remembered that the bars crates placed at a distance from each other, which must be less than the width of the insulation 5 cm. This is required to ensure that it is firmly entered between two adjacent guides.If the material will be installed in two layers, then, must be provided and installed bars thickness - it must meet two layers of insulation.

  • There are several ways to fix crate , and which one to choose - home owner decides, depending on the quality and evenness of the wall insulation.
  • After installing the boards lathing , between , since bottom row, put insulation mats.In order that they do not slip, it is possible to connect all the bars below the supporting rail.

  • In that case, if you use the web material, laying starts at the top, securing the top edge at the "fungi".The rest of the fixing elements will be installed later.
  • then laid insulation film closes vapor barrier.She often completely cover the entire wall, securing straps on the bars.Sometimes it is placed only on the heater, but the first variation nt etc. edpochtitelnee.

  • Next entire heating material with a vapor barrier attached "fungi" to the wall.
  • Over crates fixed decorative trim - it can be siding or paneling.Wiring such finishes are dealt with separately in other publications.

top of battens mounted decorative coating - siding, block-house or other materials

  • If crate installed vertically, then trim to horizontal and vice versa.This point must be considered when installing the bars or profiles.It happens, and another - with insulation in two layers.First first lathing is done horizontally, then after laying first layer of insulation, joists mounted on the second crate , perpendicular to the first .After laying the second layer of mineral wool - all the same as described above.

Evaporation heaters

addition materials in the form of mats and rolls, recently began using a liquid insulation that sprayed on the walls.These include such as ecowool and polyurethane.
