The choice of building materials in the modern market is huge. A new product is adhesive tape for vapor barrier, but despite this, it has already managed to gain popularity among consumers. The material is used for fixing the vapor barrier film and arranging airtight joints between the vapor barrier layers.
Due to the fact that modern new buildings do not have high insulating properties, which is especially true for roofs, newcomers quite often have to insulate attic rooms and attics. Poor vapor barrier manifests itself in the form of condensation, as well as an unfavorable indoor climate. If you equip it with high quality, during which tape will be used for vapor barrier, then fastening the film will ensure the durability of the structures.
The need to create tight joints of the vapor barrier
A vapor barrier layer is placed on the inside of the room, which prevents moisture from utility and residential premises from penetrating into the thermal insulation layer. If the vapor barrier has a sealed layer, which is provided thanks to a special adhesive tape, then it will retain warm air and prevent the penetration of cold masses from the street.
If you use adhesive tape for vapor barrier, this will help restore the microclimate in the house, preventing excessive air dryness, because cold masses from the street have relative humidity, which is less than that which is comfortable for humans. If you are also concerned about the issue that is described in the article, then you need to choose a high-quality tape. It is only important to decide which company to prefer.
Purpose of the connecting tape "Isospan SL"
Adhesive tape for vapor barrier "Izospan" is intended for gluing panels of materials and imparting moisture and vapor impermeability to the joints. When installing insulated mansard roofs, these tapes are used to seal the joints of the films to penetrating structures. This can be pipes, stove chimneys, ventilation systems, as well as dormers.
"Izospan SL" is used to ensure the tightness of the junction of the protective film to the building envelope. This includes the ceiling vapor barrier, which adjoins the walls of the insulated attic floor.
Technical characteristics of adhesive tape "Isospan SL"
The above adhesive tape for vapor barrier has unique technical characteristics, namely the bond strength with concrete at a separation of 0.1 MPa. As for the bond strength with the metal during peeling, it is 0.15 Kg / cm or more.
You may also be interested in water absorption. In the case of this tape, it does not exceed 0.2%. You can use the material in the temperature range from -60 to +140 ° C. Shelf life is 12 years. Sometimes, penetration at 0.1 mm is important for professionals. It ranges from 30 to 350.
Mounting Features
The described adhesive tape for vapor barrier, the purpose and installation of which is covered in the article, can be used for gluing horizontal and vertical joints of film materials. At the same time, the latter can be stacked in wall and roof structures. The tape must be glued to the edge of the reinforced cloth, placing release paper on top. Next, the next overlap sheet is laid and secured with adhesive tape, while you need to remove paper from the connecting tape. In this case, the panels are pressed against each other.
When sealing the junctions of materials to the elements and structures, the tape should be glued to a solid surface like metal, brick or concrete. Release paper should be on top. An insulating film is applied to the tape, and then you can remove the paper and firmly press the material to the surface.
Features of sticking tape on the material
Double-sided tape for vapor barrier can also be glued on the material. For this, release paper is removed from it so that the adhesive layer is exposed. The roll is mounted on the material and rolled out with a slight pressure. The recommended distance must be retreated from the edge of the panel.
The connecting tape should be used exclusively for sealing joints of rolled materials. To fix them on structural elements, mechanical fasteners like galvanized nails or a construction stapler should be used. In this case, we are talking about attaching a vapor barrier to rafters, beams, a frame or racks.
Purpose, scope and advantages of polypropylene tape “Technonikol”
Adhesive tape for vapor barrier "Technonikol" can be made of polypropylene. Moreover, its dimensions are 38 mm x 25 m. For one unit of goods you will have to pay about 155 rubles. This material is a polypropylene layer that is coated with glue on both sides. It can be used to seal the vapor barrier webs, fasten the film edges to the bases, and also when fixing the polypropylene membrane webs.
The following indicators are the advantages of this type of product:
- reliable connection of products;
- resistance to water;
- the ability to seal seams and joints;
- ease of use;
- the ability to create a moisture resistant barrier.
Such adhesive tape for gluing vapor barrier can be used in residential buildings, industrial buildings and agricultural facilities, in private houses, factories, shopping malls, train stations, warehouses, offices, public buildings, factories, apartments, catering facilities in industrial buildings.
Alternative adhesive tapes
Vapor tape for vapor barrier can be represented by products from another manufacturer, for example, Nicoband. He makes tapes for sealing different colors. Their dimensions are 100 x 10000 mm. For one unit of goods you will have to pay about 665 rubles. Such a self-adhesive tape consists of a layer of aluminum foil, the outer coating of which can have one of five color options.
The material contains an adhesive layer of modified bitumen. This tape is intended for outdoor work, it is used to seal joints, joints and cracks of various junctions. This double-sided tape for vapor barrier has excellent adhesion to roofing materials, plaster, wood, metal and concrete. The service life of the tape is 10 years.
