Polystyrene insulation of walls outside their own hands, video

Technical characteristics of polystyrene

Without going in detail into the intricacies of the production and technical characteristics of polystyrene, consider the consumer properties of the insulation. Firstly, the sheet material is rigid and that is very convenient, since it can be installed on any of vertical and horizontal surfaces. Second, it has a property advantageously retain heat in the room by the fact that consists of millions of beads filled with a mixture of air, which has low thermal conductivity. Thirdly, penoplex durable and waterproof, which makes it possible to use it in a rather harsh conditions.

Of these properties, it is clear that the technical characteristics of polystyrene foam sheathing allow them not only to the surface

indoorBut also to mount it as a component for the insulation of ventilated facade system on the outer walls of houses. To learn how to do it right, it will go on.

Algorithm polystyrene insulation of walls on the outside with their hands, video and description of the stages

To avoid trouble, before starting work, you must carefully read all the polystyrene wiring, and then begin to perform work on the following steps:

• We carry out a thorough preparation of the surface. If the walls of the house are made of bricks or blocks of light concrete, and the top covered with a layer of plaster, the deep potholes and cracks must first be repaired with putty. After it dries primed the wall to avoid its zaplesneveniya. The main task to Penoplex plate against the wall tightly without forming gaps. On the log wooden walls necessary to remove irregularities and skived too protruding parts of logs. Because of the polystyrene surface is very smooth, it is desirable dotted spiked roller for the purpose of qualitative adhesion to the wall surface. Among other things, the wall is necessary to remove all foreign objects, including windows with trim and flow;

• with the installation of the corner profile always begins outside wall insulation polystyrene foam by hand. Video of his installation can be found on the network. To describe the whole process this can be as follows. At the lower edge of the wall bordering the foundation, mark places for holes that are drilled and put them in plastic covers for the screws. Profile of galvanized steel having a T - shaped, perforated part is superimposed on a line of holes and screwed screws length of 3 - 4 cm. fixing step recommended about 40 cm. This device has the form of shelves and need to polystyrene foam sheets, smeared with glue, not slid down and rested against it.

Useful advice! When choosing the starting strip (profile) necessary to orient the thickness of the material plate. The profile should not be thicker than them. The angles are fixed strips angled connectors, and each other profile details joined plastic parts. These measures make it possible to compensate for thermal expansion of the material.

Useful advice!The best option for insulating the outer walls of the building are polystyrene plates with L-shaped edges. They allow you to fully cover the joints between them, which prevents thermal bridges appear in these sensitive areas.

• after the necessary slopes and other items will be insulated, start warming the walls outside the polystyrene foam by hand. Installation of video clips is usually filled with a variety of nuances, so it is recommended to see them. Bonding begins with the bottom row. Plates alternately plaster adhesive composition profile put on one of the sides and firmly pressed against the wall surface. When the first row is complete, begin the installation of a second, but it is done so that the picture looked like masonry joints, that is offset from the first row.

The process of bonding the plates is very important. Therefore, the clutch plates should be implemented, constantly checking the evenness of lines using a spirit level. Care must be permanent 2 - 3 millimeter distance between the plates and the adhesive protruding from the gaps have to be removed until it is gripped. In the case of negligence has turned too big a gap, it is necessary to fill with foam, not giving a chance to the cold penetrate her. At the corners the plates are cut into the outer teeth by means of which they are fastened together. This provides the necessary rigidity of corner joints and significantly increases reliability of the construction. Finger joints should be carefully prokleivat.

completion

In this exterior wall insulation polystyrene foam with your hands is not finished yet. Video of this process will tell you that after drying the adhesive plate needs to be fixed by special dowels. They have the form of hollow molds in a wide hats. The plates and the wall 4 cm drilled hole corresponding to the diameter of the dowels. The hole is inserted a fungus, and it clog long nail, which holds apart the plastic anchor inside the wall, providing secure attachment. At the same hat presses penoplex the wall tightly. It takes between 6 to 8 per 1 m² of fasteners to provide a reliable fastening to the slab surface. In areas where there are slopes and other elements necessary to increase this number. When calculating the material requirements must take into account this circumstance. Hats fungi shpaklyuyut top.

When the plates are secure, start corner treatment. To this end, the corners of plastic or aluminum is bonded to all corners, and fastened on top of the reinforcing grid reliability. It also adhered to the adhesive.

Further steps depend on what material will be covered with the facade completely. If ventilated facade system will be created, the guide profiles to attach it on top of a heater and assemble siding or the front panel. If the heater is supposed to apply a layer of plaster, it is necessary to carry out several steps:

• styrofoam slab rubbed with sandpaper and coated with glue. Then, the entire surface is glued reinforcing mesh for plaster. For good alignment of the grid surface and reliable adhesion to the plates, it must be periodically smoothing trowel, performing motion "herringbone" from the central portion toward the edges. Excess glue should rob without delay;
• when it all dries, proceed to the application of putty. Its layer should be smooth and cover the grid;
• further three days, waiting for the complete drying of the filler layer. According to their expiration, the entire surface is treated with sand paper.

Useful advice!For better adhesion to the topcoat is applied to putty special primer, a part of which has a sand of quartz. This creates a roughened matte surface, which is suitable for applying any decorative plaster mixture.

To get significant cost savings, better to carry out repair work on the outside wall insulation polystyrene foam by hand. Video and this step by step guide will help to do it properly, efficiently and save considerable finances. It is only necessary to comply with recommendations and proposed course of action.
