"Isospan B": which side should I apply to the heater?

"Isospan B" (which side to the heater to install, you learn from the article) is a material acting as a vapor barrier, when there is a need to protect the thermal insulation or other elements of the structure that can be saturated with moisture vapor during operation. The vapor barrier can be used in buildings of any purpose. In its structure, two layers, one of which is smooth, while the other is rough. The last layer allows the material to retain droplets of moisture, which evaporate afterwards.

Need to use

The use of vapor barrier material "Izospan B" allows for a long time to maintain the performance of thermal insulation. The material prevents the formation of excessive moisture, protecting the building blocks from corrosion and damage by microorganisms. As another additional function of the vapor barrier is the fact that it protects the room from penetrating inside the insulation fibers.

Which side to cover

Quite often Izospan B is used as a vapor barrier in recent years. Which side of the heater to install it, you should ask before starting the installation. At the first stage, the consumer should determine the location of the smooth and rough surfaces. According to the instruction, the smooth side should be facing the surface of the insulation, this advice must be followed strictly. The membrane is mounted on the supporting elements of the frame or on the black sheathing. Use the staples of the construction stapler as a fastener.

If the room will have a finishing material in the form of plywood or lining, then Izospan B is reinforced on the frame by wooden slats with a section of 4x5 cm. The installation works provide for a dense joining of the thermal insulation with the film. If the material is used as a vapor barrier for the roof, the horizontal stripes must overlap, and the work data must begin from the bottom. The horizontal and vertical overlap should be approximately 15 cm.

The Izospan B material is used for internal work. Which side of the insulation to lay it, you now know. However, there are many nuances during installation, which must be observed. For example, a vapor barrier can be used for an overlay device. In this case, the canvas must be laid on the ceiling joists. The material must be placed between the rough floor and the ceiling material. Between the thermal insulation and the upper layer of the membrane, as well as between the membrane and the finishing floor, a gap of up to 5 cm should be left.

Additional recommendations on the location of the coating "Izospan B"

If you, too, decided to use Isospan B repair work, what side of the heater it is necessary to have, it is important to ask before the moment of manipulation starts. For example, if the working surface is plasterboard, the membrane should be fixed to the galvanized profile. It should be tightly mounted with a smooth side to the thermal insulation. All the joints obtained and the places where the membrane will be connected to other materials, it is necessary to glue the connecting tape of the same manufacturer. Do not forget to leave a ventilation gap of 3 cm, which is necessary to exclude the displacement of the dew point and reduce the likelihood of accumulation of excess moisture.

Quite often people ask themselves about which side to have a vapor barrier to the insulation, if the latter is strengthened from the outside of the wall. In this case "Izospan B" should be installed indoors, and its rough part should be turned inward. To fix the material in all cases, you can use a stapler or slats, the last of which is nailed. Both solutions are good, the main thing at the same time - to purchase galvanized fasteners, which will serve for a long time and will not cause rusty stains.

Overlapping

After you figured out which side to put the "Izospan" to the heater, you need to pay attention to one more thing, which is the need to create a 20 cm wide overlap between the canvas, which eliminates the penetration of air under the material. If fixing is to vertical profiles, then pull the material to prevent it from sagging. A small relief is possible, but its oscillations should not exceed 50 mm.

Specifications

Today the vapor barrier "Izospan" is quite common. Which side to the heater to lay it, was mentioned above. However, you may be interested in the technical characteristics as well as the purpose. For example, the areas of use in this case are as follows:

• Insulated sloped roofs;
• Internal walls;
• Interfloor overlappings ;
• Frame walls;
• Attic floors ;
• Socle floors.

The material is available in width, which can be equal to 1.4 or 1.6 m. The area of one roll is 35 or 70 m ² . The composition contains 100% polypropylene, its breaking load (transverse and longitudinal) is 107 and 130 N / cm, respectively. Resistance to vapor permeation per square meter is 7 Pa / mg. The water resistance of the material is 1000 mm of water. Art. Within 4 months, the surface of Isospan B will be able to undergo ultraviolet radiation. It can be operated in the temperature range from -60 to +80 ° C.

Technology of steam insulation works

If you also decided to use Isospan B, which side to the heater should be laid, it is necessary to decide before starting work. More details about this have been told above. However, not only the correct arrangement of the material with respect to thermal insulation is a guarantee of successful conduct of the procedure. It is still important to comply with all the rules of technology. Thus, it should be borne in mind that the vapor barrier coating is laid in accordance with the principle that is used in the installation of the waterproofing layer. Coverage must be laid entirely, breaks should be the minimum amount. In those places where the cover is adjacent to the wall, it is important to wind it on a vertical surface of about 15 cm to exclude moistening of the thermal insulation. Steam insulation also should not be wetted during work.

Adjacent sheets should overlap, it is important to avoid the formation of voids and holes. Today Isospan B is becoming more widespread. Which side of the heater to install it, it is important to understand for yourself. But it must be remembered that in winter such work should be carried out in warm places. The surface, where the vapor barrier will be laid, must be prepared, cleaned of impurities, dried and heated. If the rolls were stored in the cold, then they are kept in the warmth for at least 24 hours. Do not carry the material over the cold from place to place.

Which side do Iospan A have?

You may be interested in the question of which side to pack Izospan A to a heater. This material is located on the outside of the wall or roof, after the wall or roof covering material. The rough surface should be adjacent to the thermal insulation, while the smooth surface is located on the side of the roofing material or the outer wall lining.

Conclusion

It is possible to vaporize the floors with the help of the Izospan material. Which side to the heater in this case lay material, was mentioned above. With the help of this vapor barrier you can work inside and outside buildings, the main thing at the same time is to understand what kind of membrane to choose.
