Tyvek covers more than 60% of the construction film market, where most of offered products manufa

If the insulation material is wet, it will not store or heat and will also reduce the life expectancy, so the film quality is of particular importance. Change substandard construction film completely change the meaning hostess buffet server of the whole construction, such as roofing. Unnecessary hostess buffet server costs, time and nerves consumption guaranteed. Building materials online store Būvserviss.lv offered brand Tyvek construction films are among the best quality hostess buffet server on the market. The question of what are the Tyvek film an advantage over other manufacturers' turn to the brand's official distributor Latvian, Ltd. ELTETE. hostess buffet server
Tyvek brand created the world-famous U.S. company DuPont, who discovered and introduced the first production of 16 of the 34 world's hostess buffet server best-known polymers. A large part of the company is manufacturing today. Among them are the names of all known as Nylon (the first synthetic fiber in the world, opened the 1938th year), Kevlar (heaviest synthetic fiber in the world), Teflon (non-stick coating), Lykra (especially hostess buffet server elastic synthetic fiber), specialists known Corian (artificial stone) , Nomex (fire-resistant synthetic fibers) Tyvex (air and vapor permeable fibers).
Tyvex fiber was developed about 35 years ago and initially used it for the construction of non-product production (aggressive weather-resistant cards and envelopes, then use "nesvīstošiem 'clothing, sleeping bags, etc.). By the time Tyvex found applications in building and were created mechanically durable, "breathable" construction films or membranes.
Today, thanks to innovations used, Tyvek, and micro-fiber microporous membrane structure hostess buffet server of these high water vapor permeability, water resistance hostess buffet server up to the water column pressure> 2m water column and longevity (certified longevity - 50 years). Tyvek fully retains its properties at temperatures from minus 73 C to plus 100 C and a brand membranes have a high resistance to UV rays.
Tyvek covers more than 60% of the construction film market, where most of offered products manufactured using a needle piercing technology. This means that per square meter of material is broadly built a number of holes. Tyvek membrane is fibrous, which increases its mechanical strength as well twisted fiber structure serves as a reinforcing material. However, other manufacturers form a layered film structure and mechanical strength to increase the use of additional reinforcing layer - increases the film strength, but reduced air permeability, because "of breathing" can not make a thicker layer without affecting its "breathing". It should be emphasized that the Tyvek construction film diffusion process is provided throughout the material thickness - from 240μm or more, in contrast to the usual diffusion membranes, where gas exchange would provide the layer thickness is only 30 - 40μm. "Of course, many manufacturers are trying to make something similar, but Tyvek level they can not achieve. This can be seen by what happens to film during operation. The packaging on technical parameters and Tyvek and other manufacturers' films are similar, but different in real life. There is a film that already after 5 years become completely inoperable, "says Andris Page, LLC ELTETE Trading hostess buffet server Group.
What are the signs says that the film used is no longer able to perform their function? This is best felt cold when the room that previously had warm suddenly become cold and hard piesildāmas requires more heat energy consumption. Total number of critical cases on the walls, ceilings, mold spots appear. "These are signs that the construction of the inserted film is no longer fulfill their function," says the specialist. In this case, there is no other solution but to completely disassemble the structure and replace the damaged building components.
It should be noted that the price difference between Tyvek building membranes and the membranes of other manufacturers is not great. Andris says: "This is not for lats but centimes per square meter. Other hand, investing a little more money to purchase high-quality construction films, you make a practical contribution to the whole building life. "Along with the purchase of films he recommends to buy special tape, complete hostess buffet server sealing of the joints of the film. Such tapes neatlīp to temperature variations of the surface and the jointing space is not conducive to the formation of heat loss.
We, construction materials Būvserviss.lv online store, a wide selection of items you buy last Tyvek brand products which are characterized by particularly high technical characteristics. Tyvek Soft - diffusion membrane with excellent vapor diffusion hostess buffet server properties and good resistance to water and wind. This membrane for use in pitched roof with insulation and wind-proof and waterproof film when applied to cotton. Solid Tyvek - along with excellent vapor diffusion properties and resistance to water and wind, the membrane is increased mechanical strength. Recommended for bias in heated and unheated roof KONSTRUKCE
