Membrane Tyvek: description, characteristics and uses

Professional builders are now familiar with the materials from the manufacturer Dupont. They are manufactured in Luxembourg and cover many industries, including:

• Agriculture;
• building;
• Power engineering;
• Food industry;
• Electronics.

However, the article deals with hydra-retroviral membranes, which are offered for sale in several varieties.

Description

In the domestic market, Dupont offers waterproofing materials, which are produced under the brand name "Taiwec". They look like compact rolls, and according to technical characteristics they can be divided into the following varieties:

• "Soft".
• "Solid".
• "Solid Silver".
• "Supro".
• "Tape.

Waterproofing films have an excellent vapor permeability, so they are known to the consumer as diffusion membranes. Such their properties allow us to fulfill the role of hydraulic protection of thermal insulation and wooden roof structures. The "Tyvek" membrane removes vapors from the insulation layer, excluding condensation on the surface of the material. The latter breathes in the direction of the roof covering layer. For this reason, the membranes have found their use even in the decoration of the facade.

The "Taiwec" membrane is characterized by the fact that moisture does not enter, does not overcome the film layer, while the air exits through the high vapor permeability of the layer. The described features are relevant for all varieties of waterproofing Dupont.

Basic properties

The membrane of "Taiwec" is actively used in hydro and wind protection of private and public buildings due to the fact that the protective functional layer has quite impressive thicknesses. This parameter can reach 450 microns, which indicates the effective work of the material during its entire service life.

The membrane is resistant to ultraviolet radiation, because the film is based on polyethylene. If on this issue to compare the membrane with analogs, the latter will be more sensitive to high temperatures. With regard to the membrane "Taiwec", it is able to undergo the influence of temperature up to 100 ° C. In addition, with its use, the consumer can save on an additional control lattice. The material has a high degree of diffusion, so it can be placed on the insulation, without forming a gap. The lifetime of constructs is increased, as is the energy efficiency of the building.

The scope of application of "Tyvek Solid"

If you decide to purchase a diffusion membrane, you should first familiarize yourself with the scope of use and the main characteristics. As for "Tyvek Solid", this material is a roofing film, which has increased strength. It can be stacked on a heater in the construction of roofs, where there will be one ventilation gap.

The membrane is extremely durable, so it can be used in structures and ventilated hinged facades and brick private houses, as well as the facades of wooden buildings. The latter can be faced with siding. The "Tajek Solid" membrane can be stacked even in cold roof structures and on roofs with a double ventilation gap. This will cause a wind load, but even it can not damage the underlay material.

This breathable membrane is one of the most common under-roof membranes for private house-building. It has been used in Russia for 15 years already. The material has one layer made of high-density polyethylene. It has a unique structure and ensures vapor permeability on the entire surface. Due to this, excess moisture is removed from the structure, and the crate and rafters remain in a dry state. The "Tyvek Solid" membrane is stacked white side down, the pattern should be facing upward. The film has a negligible weight, so it is fairly easy to lay it on the roof.

Technical characteristics of the "Tajek Solid"

This material is able to protect not only from wind, but also precipitation. It belongs to the G4 class of flammability. Flammability refers to B2 class. The tensile strength of the nail along and across is 90 and 85 H, respectively. The water column, which acts on the material, can be equal to a height of 2.35 m.

The diffusion thickness is equivalent to 0.03 Sd. The vapor permeability is 683 g / m ² for 24 hours. Resistance to vapor permeability is equal to 0, 1 m2 • h • Pa / mg. The "Tyvek" membrane, the characteristics of which should help you make the right choice, can be operated at a temperature ranging from -40 to +100 ° C. The material weighs 82 g / m ² , its thickness is 0.22 mm. One roll has a mass equal to 6 kg. Its size is 50x1.5 m (75 m ² ).

Scope of application of "Tyvek Soft"

This waterproof breathable membrane can be used to insulate frame houses with siding facing the walls. Apply the material also for pitched roofs, which have one ventilation gap. The installation of the material can be carried out by either side.

If we are talking about angles, then their slope can be equal to 15 ° and above. In places of overlapping, the canvas should be glued with a tape on a butyl rubber base. The width of the ventilation gap should be 50 mm. In the ventilation gap, it is necessary to form a control grid, which will ensure free air passage.

To mount the windproof membrane "Taiwek" you need to use slats. Brackets or nails can not take material. Leave it in such a state in the rain is unacceptable. If there is no vapor barrier in the insulated attic or there are cracks in it, as well as holes, the heater can get wet, ice may come on its surface. The membrane can be left exposed to sunlight for 4 months, but no more.

Technical characteristics of "Tyvek Soft"

The above-described waterproofing membrane "Tyvek Soft" can be laid on roofs of a mansard type. It belongs to the class of flammability G4, according to the flammability class B2. The breaking force along and across is 165 and 140 EN.

The water column acting on the material can have a height of 1.85 m. The diffusion thickness is 0.02 Sd. The vapor permeability in 24 hours reaches 744 g / m ² . Resistance to vapor permeability is equal to 0.09 m2 • h • Pa / mg. The test was carried out in accordance with GOST 25898-83. The thermal stability of the material is a limit of -40 to +100 ° C. The membrane weighs 58 g / m ² . Its thickness is 0.18 mm. One roll has a mass equal to 4.5 kg. Its size is 50x1.5 m (75 m ² ).

The cost of the membrane

Membrane "Taiwec", the price of which is 68 rubles. Per square meter, can last up to 50 years. The material is not toxic. It is delivered to the territory of Russia from Germany. By the way, that's why many consumers choose this windproof material, because it meets the European quality standards.

You can purchase the "Tyvek Soft" membrane for 6200 rubles. In order for the material to fulfill its functions, it is important to ensure its proper packing. So, when the wooden elements of the trolley are treated with chemicals, they should be left to dry for 24 hours. For the installation of "Tyvek Soft" should use racks.

Conclusion

Steam-permeable membranes play an important role in the protection of buildings, which can be residential or industrial. By purchasing quality solutions for the type of membrane "Taiwec", you create a protection that provides reliability and confidence. These materials can improve the energy efficiency of the building and ensure their long-term operation.
