Vapor barrier. For what and when is needed?

An important organizational moment in the stooping affairs is vapor barrier, the main functions of which are considered:

• condensate removal;
• adjustment of microclimate in the house (room);
• confrontation between the reproduction of the fungus, mold, bacteria;
• extension of the operational period used by building materials.

In each house, pairs in the kitchen or in the bathroom are regularly formed, which under pressure affects the ceiling, walls, roof of the house, and as a result, destroys a layer of thermal insulation, which, as it turned out, requires reliable protection. This protection in construction is just vapor barrier. Laying a vapor barrier layer is mandatory in such cases:

• when warming walls from the inside;
• When the rooms are insulated, it additionally acts as wind protection;
• When installing a good ventilation system in the house, etc.

The varieties of vapor barrier materials and the features of their choice will be discussed further in the text.

Varieties of vapor barrier material, advantages and disadvantages

The modern construction market offers the consumer a wide range of various vapor barrier materials, which can conditionally be divided into four categories:

• based on polyethylene;
• with an aluminum layer;
• membrane;
• Combined.

All of them differ from each other in price, properties, while each species has its own advantages and disadvantages. In more detail, the materials for vapor barrier are described in the table.

The main manufacturers of vapor barrier material have the following names:

• Megaflex;
• Ecolayer;
• Isospan;
• Ondutis and others.

Materials from the company Isospan are produced on the basis of polypropylene and are characterized by reliability, and a long operational period. They prevent the formation of mold on the walls and ceiling surfaces, as they have good vapor peripation. Isospan membrane is quite expensive products, but it is absolutely safe and environmentally friendly. The disadvantage of these materials can be called their tendency to rapid fire.

Materials from the manufacturer of Ecolife are characterized by a rough surface with the internal and smooth structure from the outside. They have excellent water -repellent properties, due to which they reliably protect the insulation from moisture penetration, as well as the occurrence of various fungal formations. Ecosalization materials are not suitable for organizing a temporary protective roof and require professional ventilation installation.

The company Megaflex presents on the market a number of various membranes intended to create a vapor barrier system of frame walls, etc. Materials from this manufacturer well protect the building surfaces from the effects of excess moisture and the collected condensate. The disadvantages of these products include that it is suitable only for the roof of rooms with a slope of more than 35 degrees.

The manufacturer Ondutis occupies a worthy place on the market and implements a variety of isolation materials that are suitable for both temporary and long -term use. They allow you to create moisture -repellent barriers in the room and preserve wall and ceiling surfaces. Ondutis products have acceptable prices and is characterized by durability.

Features of vapor barrier of the ceiling with your own hands

A well -mounted vapor barrier system in the house prevents heat loss and retains the primary condition of all used building materials, provides an acceptable microclimate and humidity in the room. The vapor barrier protects the insulation from dampness, as a result of which the fungus and mold are formed. The presence of vapor barrier is simply necessary in bathrooms, in the kitchen, in baths and saunas. In addition, high -quality materials provide additional fire safety in the room.

The most common vapor barrier option can be called installation using a plastic film, which is complemented by a reinforced net. In order to perform the correctly laying of the vapor barrier base with their own hands, several masters need to work, since one inexperienced may not cope, damage the film, and the material with the gap, not even large, is already unsuitable for use.

To fasten the polyethylene layer, a construction stapler is purchased, the puncture of the puncture with this tool must be fixed with tape. The main thing is to observe an uniform interval between the punctures, it should be about 1 m. Some owners use the already finished reinforced film, it is connected by special adhesive ribbons. This material is certainly more expensive, but also has a simplicity of the installation process. In addition, it is light, durable and has a low level of vapor permeability. But along with the above advantages, a reinforced net is prone to condensation, because of this lack, the demand for this material, in the case of a vapor barrier system, falls. In places with harsh winters, the hosts resort to cunning and equip the vapor barrier of the ceiling both from the inside and on the roof, which allows you to maintain heat in the house as much as possible. Thus, it turns out that two layers of vapor barrier material shares a layer of insulation.

For wooden ceilings, the presence of vapor barrier is simply necessary, since with increased humidity the tree rot and deforms. For this purpose, permamine is most often used. This material is impregnated with bitumen, a substance that repels moisture. This option is considered absolutely environmentally friendly. Due to the elasticity of the vapor barrier base, the installation process goes through quickly and almost without difficulty. Methods of installation work on laying vapor barrier with your own hands depend precisely on the type of material selected. Liquid materials are applied to the ceiling surface with special brushes and rollers. A variety of emulsions are considered no less convenient in use, they are applied with sprayers. The main thing is to perform work at a temperature of at least 6 degrees and on hard surfaces. Materials of this type are implemented in buckets of different volumes, and do not require additional dilution and heating.

The instructions for laying a vapor barrier base are as follows.

1. The ceiling surface must be cleaned of a possible web, dust. It is necessary to make sure that after wet cleaning the base is dry well. In the event that liquid materials are used, you need to exclude any irregularities of the ceiling.

2. A vapor barrier is laid on top of the thermal insulation material, while all the cracks should be excluded. The protective layer must be without ruptures and is securely fixed. Depending on the selected material, the fastening can be liquid nails, dowels, a stapler, adhesive tapes, tape, etc.

3. For sheet material, a crate is prepared in advance. It is mounted from metal profiles or from wooden planks. For reliability, experts recommend using additional fasteners of the vapor barrier base. When using a polyethylene film, it is worth understanding that it cannot be tightly pulled before fastening, since it is easily torn under pressure.

Features of vapor barrier walls with your own hands

To create a vapor barrier system on the walls, roofing material and high -tech membranes are often used. In order to work with the first option, you need to prepare special materials and tools for steamproof work with your own hands. This row includes: roofing material, nails, hammer, roulette, screws, wooden bars.

The initial stage of installation work is the preparation of a wooden crate for laying a vapor barrier layer. For this, wooden bars are used, which should be laid in a step of 50 by 50 cm, the distance must be checked with a tape measure, and the angle of laying by the construction level. Ruberoid is sewn on the finished crate, it is fixed with self -tapping screws. Experts recommend not using too many fasteners.

The vapor barrier membrane is laid on the wall from the bottom up, horizontal stripes. As a fixer, sticky tapes are used, which should be fixed at the joints of the material. You need to glue the compounds on the conscience in order to provide a vapor barrier structure with absolute tightness. In the case when the polyethylene membrane is applied to wooden walls, it can be fixed with a construction stapler or nails.

Before laying insulation on the walls, it is best to mark the surface with a simple pencil. Installations of this type are not too heavy, but require attentiveness, any errors in the size of materials or during their styling, gaps, cracks, etc. negatively imprinted on the final result. Therefore, experts identify a whole list, a number of which make up the main errors during the work on vapor barrier.

Firstly, many masters confuse which side should lay vapor barrier material, and do not pay attention to the advice of professionals. Anticandenate films with the fabric side should be placed inside the room. Diffuse bases are usually attached to installation instructions. Secondly, some craftsmen put steam insulation without insulation and vice versa. Thirdly, in the bathrooms where the tiles are laid, the masters do not high-quality vapor barrier, as a result, the wall coating is destroyed due to poorly sealed seams. The master, which provides in the room, the insulation system should understand and remember that any flaws in installation work can lead to an emergency state of the construction structure.
