Technical characteristics of vapor barrier "Ondutis"

The vocation of heat-insulating materials is to keep warm, creating comfortable conditions for living in a hot time. After a sufficiently cold winter, the outer insulation begins to thaw and, due to the lack of an outlet for the moisture formed, it becomes damp, losing its original appearance. Over time, the insulation becomes unsuitable for technical indicators. Provide full protection from condensate, moisture, wind will allow the film from the French company Ondutis.

Ondutis vapor barrier is manufactured by such a well-known French company as Ondulin, and is a membrane film coating that retains the original parameters of thermal insulation materials for the entire lifetime.

Ondutis Smart B (R70) vapor barrier provides an opportunity to insulate the walls from the inside, firmly protecting structures and insulation from condensate and steam, which occur during heating in cold weather.

If we consider the entire series of films of the company, we can conditionally divide them into several subspecies.

• Moisture protection films. Ondutis A100, A120 are moisture proof and windproof roofs and walls of the house from the outside. They are in the form of protection of external and internal structures, as well as insulation of the house from condensate, moisture and cold air.
• Super diffusion membranes. Ondutis SA115, SA130 are designed to protect insulation and interior from moisture. Promotes the wiring of water vapor through itself, while retaining moisture.
• Water and vapor barrier films. Ondutis D (RV) is a gray fabric with a stabilizer and a protective layer. Resistant to UV radiation. Also included are Ondutis RS and Ondutis D (RV).
• Steam insulation film. Ondutis B (R70) and Ondutis Smart B (R70).

If we consider the insulation films “Ondutis” B (R70) and “Ondutis Smart” B (R70), then the products can be used for various types of fencing frameworks, whether they are floors, walls with insulating material, pitched or flat roofing structures. In addition, it is comparable to many thermal insulation products made of fiberglass, basalt wool, polystyrene foam, foam concrete. The product will become indispensable for use for the internal insulation of the walls of a residential building.

The main differences of the film “Ondutis” B from “Ondutis Smart” B are expressed in the following:

• the advantage of the product "Smart" is the ability to make sticking immediately - you do not need to additionally purchase a mounting tape (during the laying the assembly joints are securely glued together, you can save a little on this);
• no adhesive layer - you will need to purchase mounting tape;
• the area of ​​the roll “Ondutis” B (P70) is 35 square meters. m. against 75 square meters. m. in roll "Smart";
• P70 film price is cheaper.

When choosing a heat-shielding film, it will be useful to know the product specifications:

• film weight in one square meter - 70 grams;
• resistance to tearing in width - 50 mm (should be eliminated increased loads and excessive bends during installation);
• temperature mode of operation - from - 40С to + 80С;
• water resistance;
• vapor permeability;
• resistance to open atmospheric influence - no more than 50 days;
• combustibility class G3;
• flammability on the B2 mark.

During installation work with the use of the film "Smart" a thin layer of adhesive strip is applied - this action facilitates further operation and reliably interfaces the webs with each other. This decision helps the buyer to save money and stop using adhesive tape for installation.

By experience, the material can be used as a light canopy for a while. As a rule, a similar roof serves no more than two months, as evidenced by consumer reviews.
