Currently, a completely new approach is being applied to the installation of the roof and its waterproofing. As a waterproofing layer, PVC membranes are used. Due to this, the roof becomes reliable, resistant to climatic factors, elastic.
The use of standard materials from Europe in the harsh climatic conditions of Russia is impossible. Therefore, domestic experts, together with Western partners, developed the superdiffusion membrane "TekhnoNikol." Due to its composition, it is suitable for use in our country.
Superdiffusion membrane "TechnoNikol". Specifications
During the production of membranes, the focus was on the following factors:
- UV protection of the roof.
- The absence of harmful and environmentally hazardous components (for example, lead).
- Fire protection.
- The ability to remove accumulated moisture (excess moisture in the warm season evaporates through the surface of the membrane).
Superdiffusion membrane "TechnoNikol" can be used on top of any base (wood, reinforced concrete, foam blocks, and so on). Waterproofing coating can be laid during the construction of a new roof and reconstruction of the old. There is a separate line, which is used to protect the foundation from moisture, wall surfaces. She is different in appearance. On its surface there are molded protrusions of small sizes.
During the installation of the roof and operation, the superdiffusion membrane "TechnoNicol" has a number of advantages, the main of which are:
- Easy installation. The membrane can be laid out with a single surface that does not have seams.
- The design does not need an additional layer of waterproofing.
- It can be used at any height, regardless of floor.
- It is not exposed to chemical damage, fungi do not appear on its surface.
- High durability. The TekhnoNikol membrane withstands a load of 1100 N on a strip 5 centimeters wide.
- Resistance to temperature extremes.
Membrane Composition
Superdiffusion membrane "TechnoNikol" consists of three layers:
- On top is a flexible base made of PVC, which resists the influence of environmental factors. Due to the chemical additives included in the composition, this layer withstands high temperatures and inhibits the effect of open flame on subsequent layers. They achieved this by adding flame retardants and refractory fillers, which reduce the rate of the oxidation reaction under the influence of high temperatures.
- The middle layer consists of interwoven polymer fibers. Serves as a reinforcing base. Durable mesh made of polymer threads withstands the long-term load of large amounts of water or snow.
- The bottom layer of gray PVC protects the surface of the structure from contact with the membrane.
Membrane types
The company’s construction films can be of two types:
- The superdiffusion membrane "Optima TechnoNicol" consists of three microporous layers. The lower and upper are made of non-woven fabric. They create a kind of frame for the central layer, which performs the basic functions. The central layer of polypropylene allows steam to pass through but retains water. This type of membrane is used when installing insulated roofs in low-rise buildings.
- The reinforced superdiffusion membrane is used for the installation of pitched roofs and for the decoration of facades of high-rise buildings. It can also serve as a temporary roof (up to 4 months) for protection from the sun, wind and rainfall.
In addition , PVC membranes , depending on the reinforcement, can be of three types:
- RP - film reinforcement with polyester mesh.
- GR - fiber reinforcement or fiberglass is used as reinforcement.
- SR - no reinforcement.
Installation of a roof using a TechnoNikol membrane
In order for the membrane to last for a long time, some rules must be observed during its installation.
The surface on which the TekhnoNikol superdiffusion membrane will be laid out must be pre-prepared. All sharp corners, debris and dirt are removed.
The material spreads gradually so that air escapes between the surfaces. It is decomposed in such a way that a single design is obtained. The individual stripes of the membrane are interconnected by soldering. Fasteners should be along the entire contour.
