Roofing film material used under any roofing, preventing the formation of condensate under the roof and on its inner part.

Roofing anti-condensation film

AT modern construction Roofing anti-condensate film is increasingly being used, which reliably protects the roof from sudden temperature changes. This material prevents damage to the roof, and also contributes to its insulation and protects the room from blowing.

The manufacture of a roofing anti-condensate film in accordance with GOST is very important, because the reliability of housing will depend on its quality.

A roof with an anti-condensation film under it has a higher wear resistance than one without it.

Underroofing anti-condensate waterproofing film

Roofing is an important component of construction, because how well it is made, the more stable the finishing plan of the object.

The production of anti-condensate waterproofing under-roofing film takes place only on modern equipment using innovative technologies. Using it during the construction of the house, you can be 100% sure that moisture will not seep under the roof of your house, and its insulation will be carried out on highest level. Using such construction material as a waterproofing polypropylene material, facade view your object will always look great.

Underroofing film anti-condensation characteristic

Today you can buy roofing material in virtually any hardware store where a specialist working in it will help you with its choice. The price of such a film coating directly depends on the density, size, thickness, tear strength and a number of other characteristics of the anti-condensate roofing film, which should be taken into account based on your capabilities and needs. The stronger and thicker the material you bought is, the more reliable the wind protection, resistance to moisture and temperature changes of the roof will be, which will bring you complete satisfaction from the construction work carried out.

Roofing anti-condensation film technical characteristics

Moscow is famous wide choice anti-condensation film roofing products, often used in construction as roof insulation. After all, such a product is famous for its ability to ensure the wear resistance of the roof, depending on its density and quality, as well as to prevent premature destruction of the roof.

The technical characteristics of the anti-condensation roof underlay film should include diffusion thickness, rupture strength when struck by a hammer, thickness and vapor barrier effect. But it should be remembered that each manufacturer indicates the characteristics in their own way.

Underroofing anti-condensate waterproofing film characteristics

waterproofing polyethylene material not only good insulation, but also provides the roof with durability, due to the fact that it does not allow moisture to pass through and protects the roof from wind blowing. When characterizing a waterproofing anti-condensate roofing film, special attention should be paid to its thickness and tear strength, because the sound insulation of the room, as well as its windproof effect, will depend on these parameters. If a person is poorly versed in films, then professional advice in this matter can help him.

Main specifications and the degree of impermeability of materials can be found in the relevant tables. Characteristic features of these products are - UV-stabilization, resistance to chemical and biological effects.

Quality assurance

UTA JSC pays great attention to technical improvement and quality control roofing films, membranes, vapor barrier films. Films and membranes are manufactured in accordance with the ISO 9001 quality management system. Quality is controlled in our own laboratory, as well as in independent domestic and foreign testing centers.

Application:

Protective roofing layer of corrugated roofing, large profiled roofing in inclined roof structures- Protective layer in roofing, wall, floor structures. Protective under-roof waterproofing layer in two- and three-frame sloping roof structures - Vapor-tight protection in sloped and flat roof structures (roof waterproofing, roof waterproofing) - Vapor-tight protection in wall and floor structures - Reflective vapor-tight protection

Main functions

Using correct design structure and the combination of an under roof waterproofing layer, a vapor barrier and a suitable thermal insulation layer, can be provided on long time optimal properties roofing and wall structures. This applies mainly to the required parameters of the diffusion balance, conservation thermal resistance structures, ensuring the watertightness of the structure. At correct application Roofing foils, due to their properties, ensure the waterproofness of the structure - just like during installation roofing, and as a waterproofing layer during the entire life of the roofing. The materials also ensure the release of water vapor into the outer space of the object. Thus, the melted snow, blown by the wind, rainwater or condensate will not disappear from the roof for inner material designs. At correct installation thanks to vapor-tight films, there is no moistening of the heat-insulating layers, which would lead to a significant increase in thermal conductivity. Therefore, the materials ensure a long service life of thermal insulation and prevent the occurrence of condensation in roof and wall structures, since water vapor does not penetrate into the dew point area in the thermal insulation space. In addition, the structure is air-tight and heat leakage is prevented. For connecting vapor barrier films, connectors are supplied. self-adhesive tapes UTAFOL SP 1 and UTAFOL SP AL.

Material Handling and Transport

Transportation is carried out in clean vehicles. Despite the fact that each film and membrane is packed in polyethylene to avoid contamination, care must be taken during loading and other types of work so that mechanical damage and rupture of the film or membrane does not occur. Products are stored in a room where UV radiation does not reach. The materials can be used in structures where the temperature range in the area where the material is placed is from -40oC to +80oC. It is recommended to connect vapor-tight and underlaying films, membranes with tape at a temperature above +5oC.

Purpose:

Roofing anti-condensation film UTACON is a material to protect against the penetration of moisture from the outside (rain and snow) into internal structure object, as well as from soot and dust in ventilated systems sloping roofs. At the same time, it prevents the condensed water vapor from running off onto the applied thermal insulation due to the use of a moisture-absorbing non-woven material (viscose).

Specification:

Film UTACON is a four-layer polypropylene UV-stabilized fabric laminated on both sides, with a special moisture-absorbing material attached to one side. nonwoven fabric. At the same time, the upper and lower layer of the laminate provides waterproofing properties and vapor permeability of the material. Polypropylene fabric provides high strength, and a moisture-absorbing non-woven material located on the underside of the film absorbs water vapor and prevents condensation of droplet moisture from water vapor rising from the internal volumes of the object. Thanks to high-quality raw materials, the film has a high durability, no less than the durability of roofing materials. UTACON has dimensions of 1.3x50 m. The film is not subject to rotting, mold and pests. Products are certified.

Mounting:

• Film UTACON it is fixed directly on the plane of rafters, logs or other building elements of the roof in such a way that the distance between them when attaching the film does not exceed 1.2 m.
• The film must not be laid directly on the formwork, other flooring and allowed to come into contact with thermal insulation.
• The minimum gap under the film should be 4 cm.
• Installation begins with the roof edging and continues towards the ridge. It must be reinforced on the supporting structure of the roof with counter rails.
• There is a black stripe on the edge of the film to indicate the recommended width of the horizontal overlap with the subsequent film web.
• After installing the film on load-bearing structure its roof should be reinforced with counter-battens. In all cases, the fit of the film in the lower area of ​​the roof and in the area of ​​the ridge must comply with the conditions necessary for the obligatory air flow, and in the area of ​​the ridge a gap of at least 10 cm must be left for ventilation.
• advantage UTACON is its strength and high UV resistance (12 months), which means that the roof can be left uncovered after filming long time unlike other roofing films.
• Other installation rules are similar to those for film UTAFOL.
