Types and features of Jutafol films

 Types and features of Jutafol films

The premises concentrate a large amount of condensate due to the differentiation of temperatures inside the object and outside. Moisture adversely affects the insulation and the supporting structures of the roof, therefore, for repair work, you need to use high quality insulation material. Well-recommended film Jutafol, which is available in various versions and is inexpensive.

Brand history

Juta produces polymer insulating film, which is actively used in construction and roofing. The company has existed for over 60 years. She began her work with the production of bags and cords of jute.From the word Juta ("jute") comes the name of the corporation, which has become widely known far beyond the borders of the Czech Republic.

Thanks to the company Juta, the Czech Republic is one of the well-known countries of manufacturers of plastic products and packaging. At the end of the 60s polymers appeared on the building materials market. Since that time, Juta retrained in the production of films for roofs, walls, greenhouses. The Jutafol trademark stands on such products as geotextiles, ordinary and mesh bags, mesh for building facade work and much more. The holding has 14 factories located in the Czech Republic. The total annual turnover exceeds 200 million euros, 4/5 of the products are shipped abroad.

The focus is on compliance with high quality standards (ISO 9001 system), the development and improvement of technology.

Specifications

The Czech brand Jutafol provides effective waterproofing. This material is marked with the letter N.

The technical characteristics of the film are as follows:

  • reliably withstands precipitation and condensation;
  • does not contain dangerous toxins;
  • combustibility depends on the brand and occurs class: B1 - flame-resistant (schwer entflambar), B3 - flammable (leichtentflambar);
  • maintains temperature in the range from - 65 ° C to + 82 ° C;
  • density - from 94 to 115 g / m2, depending on the purpose;
  • material is not susceptible to corrosion, exposure to microorganisms and insects;
  • corresponds to GOST;
  • has an international certificate of quality.

Advantages and disadvantages

Technical characteristics of vapor barriers allow it to be used in any premises. It is also possible to mount such material at any angle. Such a film can serve as much as a roof. Often the Juta polymer coating comes complete with insulation, technical wool and PVC plates.

Any product has its strengths and weaknesses. Jutafol is a universal material, in construction it is used almost everywhere. The film is a reliable barrier that protects the walls and the roof from the harmful effects of moisture. Jutafol film reliably prevents its penetration into insulation plates, which contributes to an increase in their service life. The company also produces specialized fasteners, fittings, construction glue, tape, tape, membranes.

If we talk about the shortcomings, the film Jutafol is destroyed by the direct action of sunlight.

In addition, the material does not withstand significant mechanical loads.

Species

Juta polymeric materials are perforated and reinforced coatings that are necessary for the protection and insulation of various building elements.

There are many types of Jutafol waterproofing film. It is important to have information about their technical data.

Jutafol H 90 works as an effective waterproofing, is used as a special barrier, protecting the surface from concentrated condensate. Density is only 90 g / m2.

The steam insulator Jutafol H 96 (“Silver”) is a product that is actively used in flat roofing and oblique structures. The material is a single-layer film with a density of 96 g / m2. It is often present in the insulation of walls, effectively protects the premises from condensation. When installing "Silver" it should be borne in mind that the inner layer of insulation should be much thinner than the outer layer (five times). Installation can be done by any side, with the exception of the prolonged layer, which is laid with foil inside the room. The material is effective and inexpensive. Unfortunately, the market has a large number of fakes.

When buying, it is recommended to ask the vendors for quality certificates.

Technical characteristics of the film "Silver":

  • thickness - up to 0.23 mm;
  • density - 96 g / sq. m;
  • roll size: length - 50 m, width - 1.6 m;
  • roll weight - 8 kg;
  • vapor permeability - does not exceed 84%;
  • the film resists direct UV radiation - 3 months;
  • operating temperature - from -42 ° C to + 82 ° C;
  • transverse rupture strength - 450 N / 5 cm;
  • strength of longitudinal rupture - 650 N / 5 cm;
  • flammability (flammable material) - B3;
  • installation at temperatures up to + 5 ° C.

Waterproofing film Jutafol D 110 "Special" effectively protects against low temperatures and moisture. The film is 3-ply, consists of a reinforced mesh, which is responsible for the strength of the coating. It is treated on both sides with a laminated PVC film. Intended mainly for roofing and floors. In the membrane itself, there are components that prevent fire. The three-layer reinforced structure has a density of 110 g / sq. m. Often used also for vapor barrier of vertical planes inside the premises. You can also include a foil in this category.

Jutafol "Standard" is well known in Russia. It is used most often for roofing structures.

It has the following specifications:

  • density - 110 g / sq. m;
  • vapor permeability - 0.4-0.6 g / sq. m;
  • longitudinal rupture strength - 221 N / 5 cm;
  • transverse rupture strength - 191 N / 5 cm;
  • combustibility class - weak B1;
  • roll weight with dimensional parameters 1,5х50 m - 8,8 kg.

Jutafol NAL 170 "Special" is used for processing both roofs and vertical planes. The coating consists of four layers: reinforcing mesh, lamination on both sides. The base consists of aluminum (4th layer), which effectively performs the heat-reflecting function. If there is a need to isolate a room with high humidity, then in this case it is best to purchase a similar film with a density of 170 g / sq. m

Durable Jutafol tape "SP1" (made of butyl rubber):

  • provides strong contact with the nodes that penetrate the film;
  • guarantees reliable connection with metal nodes of the roof;
  • is a stable mount for vapor-permeable coatings;
  • protects the tightness of the joints.

Juta Eurobarrier is used as a protective thermal insulation layer., also protects the rafters, bearing wooden structures from excess moisture, temperature difference.The advantage of the euro barrier is that the condensate from the house freely goes into the external environment, and the moisture from the outside does not penetrate into the object. The structure of the Eurobarrier Juta consists of three layers of polypropylene material: external ones provide strength and protect against UV radiation, the inner layer ensures effective vapor permeability, as well as protection from moisture.

Vapor barrier film (vapor barrier) Juta is used on the inside of the object. Designed to isolate the roofing areas on roofs of all kinds. Often also used for facade insulation. The film reinforced, happens density from 90 g / sq. m. to 110 g / per square. m

Juta barrier is also a kind of under-roof insulation. The material is installed in the roofing space, effectively protects against leakage in case of unexpected damage to the roof. It is used on pitched roofs.

Prices of films from the company Juta in rubles per roll:

  • H 90 - 380;
  • H 96 Silver - 1,160;
  • H 110 "Standard" - 1 260;
  • H 110 "Special" - 1 840;
  • H AL 170 "Special" - 3 100.

Vapor barrier is installed only after the entire insulation is laid. It is important to control that the material is in close contact with the previous layer. The film is attached to the rafters using a large stapler with a pitch of approximately 25–45 cm. The layers must be overlapped (width 15 cm) so that moisture cannot penetrate. The edges are fixed with a special tape, wooden planks are put, which are nailed to the logs. The distance between them should be about 40 cm. These bars are the main basis to which the sheathing is attached.

Often confused two materials H96 "Silver" and waterproofing D96 "Silver". The difference between them is that the waterproofing has a higher density, and it also has no perforated edges.

Additional elements

During construction, for example, attic, wooden walls, bearing beams, rafters, roofing are wrapped with film from the inside. Before this, all the structural elements are processed with a primer - antiseptic. During such work, it is impossible to do without special aids: adhesive connecting tapes and adhesive tape. Jutafol produces dozens of such products, which can be used for various types of work.

Here is just one example: durable polypropylene tape "U-1" with one-sided coating. Ideal for attaching film to rafters. Reliably protects from drops of moisture on the supporting structures.

Also such tape isolates joints and slots during installation of thermal panels.

Instructions for use

The Juta membrane for roofing is applied only horizontally: from the edging to the ridge. Vertical and horizontal overlap should be at least 12 cm (depending on the roof pitch). Fastening is realized with the help of staples or special galvanized flat nails.

The rate of installation of the film, depending on the angle of the roof

The slope of the roof is degrees.

If the film is mounted where the integrity of the roof is broken, for example, at the installation site of the antenna or the ventilation pipe, then it will need to be carefully cut a hole and attached to the protruding elements using a double-sided adhesive butyl rubber tape.

Work with vapor-permeable film begins with its fasteners to the rafters or any other supporting structures.

  • Usually the distance between the rafters is not more than 1.1 meters.It is acceptable for the film to sag no more than 2 cm.
  • After fixing the film comes the turn of counter-tracks, which are nailed. In this way, the desired condensate drainage will be ensured. Usually used 3x5 cm counter racks.
  • The edges of the Jutafol "Standard" and "Special" are painted with bright paint, they should be adjacent to the roof.
  • Jutafol "Silver" has a dark side.
  • The film can not be put on the formwork or close the joints.
  • Counterstrikes (3x5 cm) should be laid between the film and the supporting structure, the step should not exceed 1.15 cm.
  • The film should not lie on the ground.
  • The allowable gap between the insulation and the film is about 3 cm.
  • Installation of the film in the area of ​​the ridge and the lower part of the roof should be carried out so that air exchange is present (no more than 4 cm).
  • All joints are closed with a special tape "SP 1".
