To increase the service life of the roof, it is necessary to comply with a huge number of requirements, as well as perform activities that will ensure the maintenance of the temperature regime, protect against precipitation and create appropriate operating conditions.
Content
It is for this purpose that the modern waterproofing of the roof is intended. To date, steam and waterproofing building materials provide reliable and qualitative execution of this multistage process. Their main purpose is to prevent the occurrence of condensate and maintain the integrity of the roofing insulation.
What is the roof hydrocario insulation?
The basic purpose of building materials intended for waterproofing roof is the protection of the insulation from moisture, which helps to reduce its working properties. Its hit can occur not only in the form of condensate arising on the surface and inside the coating due to the temperature difference, but also from the air.
Hydro-eyed building materials can be divided into several groups:
1. PAROCONDSENT WATER POLICING FILMS
They create additional protection of the roof from leaks, penetration of precipitation to ventilation inputs, etc. Their installation can occur both for waterproofing the cold roof and for warm.
2. Diffuse membrane building materials
It is more modern material that is capable of producing a steam release rising to the roof from interior. Their installation is produced on the inside of the insulation.
These two types of building materials most often have layers between the heat insulating layer and the roofing base, since this method allows you to prevent the absorption of moisture insulation.
Polyethylene films, which are used for steam and waterproofing roof, should always be rejected by a special cloth or reinforcement grid, which will give strength to the most building materials. Today you can find quite a lot of their manufacturers, but the best of them - Eurofol - Braas, Jutacon - Juta, Izospan, Jutafol D - Juta, Kruveol, Rankka / AntiCon - Rannila and others.
The main advantage of polypropylene reinforced films is:
- increased strength;
- Resistance to ultravioleti;
- Application not only in the form of hydro, but also vaporizolation, thanks to anti-condensate special coating and high parangments.
Breathable membranes create wonderful protection against moisture and while remain absolutely available for the exit of water vapor thermal insulation. This is ensured due to a special microstructure, which is a nonwoven material consisting of synthetic fibers. Top Manufacturers: Jutawek - Juta (Czech Republic), Tyvek Soft (Luxembourg) and others.
Production
Today, membrane films are manufactured in the form of three- and two-layer materials, which simultaneously have a diffuse property and anti-condensate. In addition, they may include a layer of adsorption, which accumulates condensate and effectively evaporates it.
Building materials intended for vapor and waterproofing are more often made in the form of rolls, which greatly simplifies their masonry, allows us to seal the edge connection and remove the seams as much as possible. They are recommended to be used regardless of the type of roof and the material for its coating: waterproofing of the pitched or operated roof, coated with metal, tile, etc.
Hydro-eyed roofing
Waterproofing liquid rubber is the most popular and modern method of protection of the design from penetration, which allows the roof to function in optimal mode, prolongs its service life and provides the necessary comfort in the room.
The correct installation of a roofing pie for which the necessary building materials for vapor-and water insulation are used, as well as a special insulation, maintains heat in the building, reduces heating costs and prevents the penetration of condensate and moisture into residential space.
Creating gaps for ventilation and installing a film for waterproofing the roof system allows it to last a long period of time.
Ventilation protects the coating from heating from the building side and allows you to create a uniform melting of the snow cover under the action of the sun or heat, thereby preventing the occurrence of the land, which leads to damage to the mounted gutters and drainage.
As for diffusion membranes, they have a rather high cost, but they differ in the whole number of advantages:
- have waterproof from the outside and increased vigilant vapor permeability from the inside, which ensures the "breathing" of the roof;
- Thanks to the wind-leverafficness, membranes, the amount of heat invested from the surface layer is significantly reduced;
- They can be installed directly on the insulation, which, accordingly, reduces the thickness of the roofing pie and the use of thick layers of thermal insulation.
How to put hydropara insulation
In the process of installing waterproofing with a flat or other roof, a vapor barrier film can be fixed not only vertically, but also horizontally.
Laying hydrocariolar insulation 2 ways:
1. The horizontal laying of the film occurs on the rafters, which should be at a distance of up to 120 cm from each other. It is not recommended to create contact with a layer of insulation and a sagging of more than 20 mm. After fastening the film, counterbours are fixed to the rafters and the doomle is being built.
2. The vertical method of the film is attached to the brackets of the mechanical sewer or nails galvanized with flat heads. It is fixed to the wooden carrier elements along the inside of the heat insulating layer.
Recommendations:
- In both cases, the fastening of the film must be observed to observe the totaling minimum of 100 mm;
- If there is a connection of individual rolled strips of the film, it must be sealed and created using a special connecting tape;
- Upon completion of the film, it is necessary to consolidate special rails that will ensure not a very large free space between the ceiling and the parobararier;
- By purchasing products, carefully study the accompanying recommendations, instructions and inscriptions located directly at the building material. This will help you avoid mistakes in its application. Accordingly, the question of which side to lay hydropara insulation is will disappear by itself.
Thus, thanks to innovative building materials and technologies, hydrocarproolation of the roof also improved. Therefore, today absolutely everyone can afford to create the necessary air temperature in the room and control the level of humidity.
