Thermal insulation of exterior walls with fiber, foam or mineral wool

     Technology insulation includes the following operations:
1. The facade is cleaned of hollow and damaged plaster
2. Installation of the insulating panels - to be effective insulation should be used sails insulation layer at least 5 cm. For an XPS and EPS. With this thickness is reached the statutorily defined koefitsinet transmittance Umax for envelope structures according to ordinance №18 MEER. Toploizolatsionnite sails are attached to the facade using glue and dowels. Apply adhesive "comb" with a notched trowel evenly across the entire canvas or piles and stripes, the contact surface must be at least 40% of the surface of the canvas. Installation of sails is done in the direction of bottom-up which ensures better sealing joints between lanes. After gluing, riveting sails using special plugs by placing as many as required are, but not less than 6 per square meter. In brick used special plugs brick. Some windows are glued strips of XPS 2 cm., If it allows the woodwork. An important point in the installation of the boards that must cover at least 20 cm. The upper panel joint to ensure penetrating water in the house.

     * If the wall surface is uneven canvas smeared Framework (on the perimeter of the entire canvas) and in the middle was placed 2 "balls" with adhesive mixture.

Putting it anchors 24 hours after gluing the boards to make sure that the glue is cured and not risk dowels deform already leveled and aligned well plates.

Dowels to strengthen the insulation is divided into three main types:
- PVC plug for concrete, concrete and brick thick - nail plastic cup, which rammed into predrilled hole.

- PVC dowel nail hollow brick - plastic dowel with a plastic nail first strikes plugs, which is cut and then put the nail and which dissolves very plastic dowel.

- PVC dowel nail mineral wool (PVC dowel nail with PVC and PVC plug with metal nail with PVC or metal cup) - the same plug for hollow bricks, but with a wider cup.

The anchor fills the cavity volume and thus fixes it. When attaching to a solid base of brick or concrete, it dissolves, entering the dense contact holes on the wall.

  3. Corner profiles and pre-coat - after the installation of insulation panels are made the first coat with specialized adhesive for thermal insulation. This glue than increased strength of adhesion to polystyrene basis, contains polypropylene or polyester fiber, which increase Crack resistant putty. The preliminary coat is made only with glue and aims to create a good basis for the second coat with network and leveled some bumps. Together with the putty is plastic and mounted to the corners of all network edges (without the bottom, with the exception of the balcony). Their aim is on one hand to strengthen those most vulnerabilities, and the other to give a better aesthetic appearance.

   4. The main plastered with network - after drying the first coat is performed mainly by alkali glass reinforcing mesh (fiberglass or fiberglass mesh) weighing 145 g. / Square meter The network must cover the entire insulation - should not go places without network. Overlaps between different networks must be min. 6 cm, in order to ensure the homogeneity of the structure. To coat again using specialized glue or putty for thermal insulation, as in addition to good mechanical properties, it has increased water-repellent capability.

Another important element of the insulation is to protect the upper edge, as it is most exposed to erosive action of dripping water on the facade. Besides the immediate danger of falling water behind insulation and washing the plaster at the top, there is a risk of frost and the wet plaster winter in which it is easy to crack. To protect the insulation from these adverse effects, the upper edge is coated with waterproof silicone sealant, then mounted visor-draining galvanized steel or Water dripping ending angles.
Other accessories toploiozolatsionnata system:

- Water dripping angular profile with a network (water protection)
Water dripping profile (water protection) - prevents the flow of the water on the facades and contribute to creating a perfect ending horizontal areas (sills).
- ALU and PVC protective profile network
ALU and PVC angle with gauze to protect the internal and external corners of structures and thermal insulation systems.
- Protective angle profile walls - PVC and ALU
Protection profile for secure and protect the inside corners of structures.
- Initial ALU profile insulation Water dripping

5. Application of the plaster surface - after completion of insulation, it should be protected from exposure to water and solar UV rays, but also and give good looks. This is achieved with the application of plaster. This layer contributes to increased reliability and durability of the insulation. All surface coatings are called plasters are more "light" or "noble". Have good water-repellent properties, very good permeability, frost resistance, prevent the penetration of harmful gases and microorganisms not swell when moistened, non-flammable.
Comparison between internal and external insulation
I. Internal insulation:
1. The air in the room is heated much faster, but faster then cool.
2. The interior space is lost from the room.
3. The room is sealed from the inside out, thereby reducing the heating of the outer walls of the hot air in the premises, which in turn creates conditions for freezing of walls, corrosion stomaneno- fixtures and more rapid wear of the façade plaster .
4. Do not seal the joints of panel blocks and prevents any ingress of moisture therefrom.
5. Due to the nature of the materials they are made of heat-insulating panels / particularly EPS / and the fact that they are relatively soft, it is possible mechanical deformation of their surface, as a result of which the putty and fall from the walls.
6. The main reason for making an internal insulation is the fact that much of the neighboring apartments in a block are often turned off heating, thus losing energy to them.
II. External insulation:
1.Edinstveniyat disadvantage of external insulation is much more difficult and mounting.
  To However isolation of one room fully effective, it is recommended to be done inside insulation with thin material - for example depron, cork tiles, wallpaper, etc. insulation. This ensures faster warming of the room and lower losses in the intermittent heating, although it loses the storage effect of the walls.
