Professional builders today are familiar with the materials from the manufacturer Dupont. They are manufactured in Luxembourg and cover many industries, including:
- Agriculture;
- construction;
- power engineering;
- food industry;
- electronics.
However, the article will focus on hydro-windproof membranes, which are offered for sale in several varieties.
Description
In the domestic market, Dupont offers waterproofing materials that are manufactured under the Tyvek brand. 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 excellent vapor permeability; therefore, they are known to the consumer as diffusion membranes. Their properties make it possible to fulfill the role of hydro-wind protection of thermal insulation and wooden roof structures. The Tyvek membrane removes vapors from the insulation layer, eliminating the formation of condensate on the surface of the material. The latter breathes in the direction of the covering layer of the roof. For this reason, membranes have found their application in the decoration of the facade.
The Tyvek membrane is characterized by the fact that moisture does not enter inside, does not overcome the film layer, while air leaves the outside due to the high vapor permeability of the layer. The described features are relevant for all types of waterproofing Dupont.
Basic properties
The Tyvek membrane is actively used in hydro and wind protection of private and public buildings due to the fact that the protective functional layer has rather impressive thickness indicators. This parameter can reach 450 microns, which indicates the effective operation of the material throughout the entire life cycle.
The membrane is resistant to ultraviolet radiation, because the film is made on the basis of polyethylene. If on this issue to compare the membrane with analogues, the latter will be more sensitive to high temperatures. As for the Tyvek membrane, it is able to undergo a temperature effect of up to 100 ° C. In addition, with its use, the consumer can save on an additional counter-grill. The material has a high degree of diffusion, so it can be placed on the insulation without forming a gap. The lifespan of constructs is increased, as is the energy efficiency of the building.
Scope of Tyvek Solid
If you decide to purchase a diffusion membrane, then you should first familiarize yourself with the area of use and the main characteristics. As for Tyvek Solid, this material is a subroofing film that has increased strength. It can be laid on the insulation in roof structures, where one ventilation gap will be present.
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 Tyvek Solid membrane can be installed even in cold roof structures and on roofs with double ventilation clearance. In this case, a wind load will occur , but even it is not able to damage the subroofing material.
This breathable membrane is one of the most common subroofing membranes for private housing construction. It has been used in Russia for 15 years. The material has one layer made of high strength polyethylene. It has a unique structure and provides vapor permeability over 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 laid with the white side down, the pattern should be facing up. The film has a small weight, so it is quite easy to lay on the roof.
Specifications of Tyvek Solid
This material is able to protect not only from the wind, but also precipitation. It belongs to the G4 class of flammability. Flammability refers to class B2. The tensile strength of the nail along and across is 90 and 85 N, respectively. The water column that 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. The vapor permeability is 0, 1 m2 • h • Pa / mg. The Tyvek membrane, the characteristics of which should help you make the right choice, can be used at temperatures ranging from - 40 to + 100 ° C. The material weighs 82 g / m 2 , its thickness is 0.22 mm. One roll has a mass of 6 kg. Its size is 50x1.5 m (75 m 2 ).
Scope of Tyvek Soft
This waterproofing breathable membrane can be used for insulation of frame houses with wall siding. The material is also used for pitched roofs, which have one ventilation gap. 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 overlap of the canvas should be glued tape on a butyl rubber basis. The width of the ventilation gap should be 50 mm. In the ventilation gap, it is necessary to form a counter-lattice, which will provide free air passage.
To install the Tyvek windproof membrane, use rails. You cannot grab material with staples or nails. Leaving it in this condition in the rain is unacceptable. If there is no vapor barrier in the insulated attic or there are cracks and openings in it, the insulation can get wet, ice can freeze on its surface. The membrane can be left under the influence of sunlight for 4 months, but no more.
Specifications of Tyvek Soft
The above waterproofing membrane "Tyvek Soft" can be installed on the roof of the attic type. It belongs to the combustibility class G4; according to flammability, it belongs to class B2. The breaking force along and across is 165 and 140 EN.
The water column acting on the material may 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 . The vapor permeation resistance is 0.09 m2 • h • Pa / mg. The test was carried out according to GOST 25898-83. Heat resistance of the material is equal to the limit from - 40 to + 100 ° C. The membrane weighs 58 g / m 2 . Its thickness is 0.18 mm. One roll has a mass of 4.5 kg. Its size is 50x1.5 m (75 m 2 ).
Membrane cost
Membrane "Tyvek", 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 Russia from Germany. By the way, that is why many consumers choose this windproof material, because it meets European quality standards.
You can get the Tyvek Soft membrane for 6200 rubles. In order for the material to fulfill its functions, it is important to ensure its proper installation. So, when the wooden elements of the crate are treated with chemicals, they should be left to dry for 24 hours. For mounting “Tyvek Soft”, use rails.
Conclusion
Vapor permeable membranes play an important role in protecting buildings, which can be residential or industrial. By acquiring high-quality solutions like the Tyvek membrane, you create protection that provides reliability and confidence. These materials can increase the energy efficiency of the building and ensure their long-term operation.
