Scotch tape for vapor barrier - types of adhesive tape for the roof + Photo and Video review

Scotch tape for vapor barrier - types of adhesive tape for the roof + Photo and Video review Features and types of adhesive tape for gluing vapor barrier. Installation, construction or repair work is carried out using various sealing compounds and fixing devices. But to perform such tasks, there are not only powder and liquid products, among the huge variety of products, special attention deserves an adhesive tape for vapor barrier, which is used to perform vapor barrier of structures and buildings.

Every construction of premises, in particular residential buildings, will not do without the use of raw materials for vapor barrier.

The presence of such material (most often it is a vapor barrier film) makes it possible to provide excellent protection to all important components of the structure from moisture ingress, which has a destructive effect on many surfaces.

General information

Purpose and features of the material

Please note that in addition to this, the presence of membranes helps to eliminate the risk of condensation entering the room, and this saves rooms from the formation of mold and mildew on the base.

Errors that are made when installing materials for vapor barrier can lead to the accumulation of excess moisture in a house or apartment, due to which the material for insulation will lose all useful properties, and after a while will begin to collapse ceilings on walls and ceilings. It is for this reason that the competent laying and gluing of vapor barrier material is an important milestone for the durability and construction of residential structures.

Scotch tape for vapor barrier - types of adhesive tape for the roof + Photo and Video review When creating a roofing cake, the vapor barrier tape is the most important element that helps to provide the required waterproofing barrier along with the materials for arranging the roof. Usually, bitumen tape is used to perform waterproofing, which looks very much like construction tape.

Window structures, which are mandatory for every building, require good protection for the wall and frame joints. For this reason, in addition to the standard polyurethane foam, it will also be necessary to glue joints and corners with the help of a reliable sealant, which is available on the construction materials market, and is sold in the form of construction tape.

This product is presented in the form of a special-purpose tape, which is required for gluing various elements together. A feature of the tape can be called its ability to create excellent insulation of seams and joints from steam and moisture entering them. It should also be noted right away that the use of standard stationery tape will not be appropriate for construction work, since after a certain time the product will begin to gradually peel off, moisture will pass through the gaps formed, and that, in turn, will destroy the layers of material for thermal insulation.


Scotch tape for vapor barrier is a special construction tape, which comes in different structures and sizes, the scope of which is to create good sealing of joints of vapor barrier products. In fact, it is an adhesive tape for waterproofing and vapor barrier, which appeared as a new product in the modern construction market. But due to their unique characteristics of properties, such products for gluing have already become insanely in demand and popular among consumers.

Such a demand for a product is quite understandable: the poor quality of insulation of seams and joints in buildings that were built relatively recently. For those who have finally moved into their own apartment, and their housing is adjacent to the attic, the question is especially relevant, since a poorly made vapor barrier after a while will begin to negatively affect the microclimate in the apartment.

In addition, the tightness that the vapor barrier tape provides makes it possible to prevent the rapid release of heated air from the apartment and the ingress of cold air from the street.

Scotch tape for vapor barrier - types of adhesive tape for the roof + Photo and Video review Based on the characteristics of the tape, you can use it to secure and seal film joints that are located in the vertical and horizontal direction ... The adhesive tape should be glued to the very edge of the base, while adhesive paper must be placed on top.

After this, it is required to lay another sheet of film overlapping with a vapor barrier tape, pressing each joint.

To ensure high-quality sealing in the places where there was a connection of materials and parts, the tape should be fixed on a solid base, for example, on brick, metal and concrete. Double-sided materials can be attached immediately directly to the material. To accomplish this task, remove the adhesive paper from the surface, and then place the entire roll of tape in the desired direction, roll it out on the base and press down a little along the way. In this case, retreat a certain distance from the edge of the panel.

The tape is used only for sealing the joints of materials, and their fixation to the working surface during the laying process will be performed using fasteners. Most often, nails are used for this type of work, or fastening is performed using a construction stapler.

The adhesive tape for gluing the vapor barrier has the following characteristics:

  • Resistant to UV rays.
  • Low moisture absorption, only 0.25%.

  • Resistance to atmospheric phenomena.
  • The product will not lose its properties even at temperatures from -40 degrees to +75 degrees.
  • High adhesion to metal, concrete, wood and film.
  • The service life is 15 years.


All vapor barrier tapes, without exception, are based on glue, and this feature helps to eliminate the need to apply the composition for pasting yourself.

This reduces the risk of poor-quality fastening, and this can lead to moisture ingress on the thermal insulation material.

Interestingly, the classification of products is performed on the basis of the original material, that is, the raw materials that will be used for production, as well as the structure of the product.

By its structure, construction vapor barrier tape is one-sided and double-sided. I use the first type of product so that the materials are attached end-to-end. Products of the second type make it possible to overlap the canvases.

Taking into account the raw materials from which the ribbons will be produced, products can be divided into the following varieties:

  • Scotch tape for vapor barrier - types of adhesive tape for the roof + Photo and Video review Aluminum tape - is a special composition, which contains an aluminum tape and its thickness can vary, 20-40 microns, as well as a protective base and an adhesive. The products have already received positive reviews, but unfortunately, there is also a drawback to which we will attribute the fact that such a tape cannot be used for all types of vapor barrier films. Usually, the width of the aluminum tape is from 5 to 10 cm.
  • Reinforced aluminum tape - these types of products are highly durable, and unlike the previous type of tape. This characteristic is due to the fact that the product contains a strengthening reinforcing layer.

    Scotch tape can be from 5 to 10 cm wide.

  • Polypropylene tape - such products have an attractive cost and are sold in every hardware store. In this case, the statement about the low quality of an inexpensive analogue is fully justified, since experts have tested and noted the unreliability of fixation when working with polypropylene tape and vapor barrier films. Usually the width of such tape is no more than 5 cm, otherwise the thickness is 100 microns.
  • TPL adhesive tape is a special product made on a textile basis with an adhesive based on rubber, as well as with a polyethylene surface on one side.

    Self-adhesive rubber products are not used very often for installation work. It has a fairly large thickness - as much as 200 microns, and the width is standard 5 cm.

  • Butyl rubber tape is a product that is quite advantageous against the rest, since such tape has a high level of adhesion to vapor barrier materials. The disadvantages of the product include a large specific gravity of the material, which is 5 times greater than that of an aluminum tape. The width of the product is from 1.

    5 to 5 cm.

Important! We also note that rubber tapes are most often used for windows, door structures and balconies.In rooms with high humidity, metal-based products are used.

In addition, there is a classification of tapes by climatic purpose:

  • For use at sub-zero temperatures, manufacturers began to produce even "winter" variations of products, which will not lose their properties from the action of frost.
  • "summer" films are advised to use at an average positive air temperature.

Size grid

The table on the sizes of products that are presented on the rank looks like this:

  • Materials with a length of 25 meters have a width of 1.5, 3, 5, 6, 7.5 cm.
  • Materials with a length of 30 meters have a tape width of 1.5 and 6 cm.

  • Materials with a length of 23 meters have a width of 1.52 cm.

How to choose the right one?

To make the right choice and buy a suitable vapor barrier tape (double-sided or single-sided), you should pay attention to the following characteristics of materials:

  • Scotch tape can be used to perform sealing in specific places of structures and residential buildings, therefore, the resistance of a product to ultraviolet radiation is the most important criterion for buying a particular type of product.
  • The scotch tape must be such that it does not absorb water, otherwise there is a great risk that the vapor barrier and heat insulation materials will be damaged.
  • Products with high quality must necessarily have resistance to heat, and equal to +90 degrees.

  • Tape adhesion to different surfaces. There are several types of materials that cannot adhere well to metal substrates.
  • Typically 15 years average life, but may vary from manufacturer to manufacturer.

* When buying a vapor barrier tape, check the service life from a sales consultant.

Recommendations and expert advice

Features of working with scotch tape require certain rules to be followed:

  1. You can only perform all manipulations with the tape on a well-cleaned and completely dry surface.

  2. After that, unfold the sealing vapor barrier sheet, which should be glued with tape along the entire length and width.
  3. Then remove the top layer from the tape.
  4. The end of the work will be the laying of the second layer of insulation, which will be glued to the product located under it.

Vapor barrier materials are more reliable and correct to fix with double-sided vapor barrier tape. On the second layer, you can also use one-sided tape with adhesive.

According to consumer reviews, the highest quality fixation is obtained when using butyl rubber construction tape.

As for the window and door openings, in this case, experts advise to perform work according to the following scheme:

  1. After the surface is cleared , mark the line along which you will stick the tape. This task is performed when the box or frame is installed in the opening without fixing.
  2. After that, the structure should be removed, and the tape should be glued to the marked area.
  3. The final step is to cover the installed tape with foam, but before that you will need to remove the paper base on the tape.

  4. Work with the joints of the material under the windowsill is carried out last.


In some cases, after laying the vapor barrier layer and installing the adhesive tape, it is planned to apply a plaster layer to the surface. To do this, experts recommend giving preference to those types of tapes, the open part of which will be from raw materials that have excellent adhesion to decorative types of coating.

Also, we do not recommend buying products from brands that are little known, especially those from Asia. The use of such products in residential buildings may become unsafe for human health, since there are no guarantees that there are no toxic substances in the composition.

In addition, the quality of fixation is unlikely to be good for sealing joints. It will be better if you buy products from a world famous company.
