What materials to choose for work on the insulation of seams?

In modern technologies for processing interpanel seams, materials based on complex polymers or synthetic rubber are mainly used. They have a long service life and high quality characteristics.

The specialists of our company in the production of work use materials only of those brands that have passed the tests, have the necessary quality certificates and have proven themselves in the market. In particular, the Vilatherm cord, which is the main material for insulating seams, is polyethylene with a low level of thermal conductivity, which ensures the preservation of heat in the room. The main property of the polyurethane foam is low resistance to ultraviolet rays. Its main task is to fill all the voids and cracks in the interpanel seams, but in order to prevent its destruction under the influence of sunlight, additional protection is needed. This protection is provided by the sealant. In addition to ultraviolet light, it also prevents moisture from entering the seam.

Polyurethane foam does not lose its properties even during frosts, but direct sunlight or contact with petroleum products, especially oil or gasoline, is categorically contraindicated for it. This has a destructive effect on the material. Finishing is carried out using Oxyplast sealant, which is made from synthetic rubber. This sealant is waterproof and protects the insulation from atmospheric precipitation. The sealant hardens in 5-7 hours after application, and its properties remain for 10-15 years. When carrying out insulation, it should be remembered that the greatest heat loss in panel houses occurs precisely through the seams, so you should not save on this procedure! It is better to make it of high quality, since it will pay off by optimizing heating costs.

Thus, the use of modern polymeric materials allows for high-quality processing of interpanel seams and keep warm in the house. The main thing in this case is to strictly observe the technology and to prepare the surface for processing with high quality in order to ensure a high level of adhesion of materials. As a result of the insulation of interpanel seams using the described "warm seam" technology, problems with the penetration of moisture or cold into the room can be forgotten for a long period.

Main advantages

When choosing a material for certain jobs, it is important to take into account not only the characteristics, but also the advantages over other materials used in this area, or direct competitive analogs. This will allow the most accurate comparison to select the product that suits your requirements!

Among the main advantages of Vilaterm are the following:

It is very convenient to work with the material. Cutting with an improvised tool, the use of cuts and residues is practically waste-free. The ability to replace the material with another one with different characteristics;
Ease of purchase. Large assortment of standard sizes: diameter of heat-insulating bundle from 6 to 80 mm, length - any;
Convenience of delivery. Light weight, so you can deliver the cord in a package, bag, trunk, and in small quantities, even in your hands, giving it a comfortable shape and fastening it with tape;
Choice by structure and type of material - a hollow tube and a one-piece, more compression-tight cord;
Density of Vilaterma - 25-40 kg / m3, choice for different requirements and working conditions;
Working temperature of the material from -60 ° С to + 80 ° С;
Elasticity - 0.26-0.36 MPa;
Thermal conductivity of Vilaterm - 0.04 W / m ° С;
Water vapor permeability about 0.002 mg / MhPa;
Water absorption within 3% by weight!

You can compare the data with other materials, because there are really a lot of analogues, and even earlier, few people used a porous elastic tourniquet in their work. It is today that advertising campaigns for it are strong, and thanks to this, the products overwhelm the market!

Assigning material

Construction - log houses, log cabins, panel residential and technical, industrial facilities;
Finishing works: sealing expansion and heat shrink joints, joints inside the premises. Work with ceilings, floors, installation of damping lines, laying in shrinkage joints, for soundproofing partitions by limiting vibration transmission;
External works: sealing of seams and joints of wall panels in low-rise and high-rise construction, seams of blind areas, garden paths, preliminary laying of concrete sites in the seams;
Thermal insulation work with roofs, walls, floors - reducing heat loss and limiting the access of cold air;
Application as a sealant in almost any related field;
Insulation of doors and windows, slopes and junctions of frame structures and the main walls of the building;
Sealing of structural joints of various parts and their bases in refrigeration units, ventilation ducts and equipment;
Use as a shell, a shell for water supply and sewerage pipes for protection, as well as limiting heat loss, eliminating condensation!

In practice, Vilatherm cord can be applied many more places on demand and compliance. But it is worth starting from the main directions!

Sealing seams - how to order.

Repair of seams of panel houses is carried out by industrial climbers. To work, industrial climbers will need official permission from the Management Company to access the roof (roof access).

To gain access to the roof, you must sign a letter and a package of documents from our organization, as well as an application from the customer to the Management Company and the district GUIS. We will carry out these activities ourselves. True, in some areas the presence of the customer is required. If you have an HOA, then it is enough to provide the documents to the chief engineer and you can agree on the day of work on sealing the seams of your apartment.

In order to place an order with us, the Customer is required to fill out an application using any link ("PLACE AN ORDER FOR SEALING", "ONLINE ORDER", or by e-mail), leave your contact information. The term of registration by us of access to the roof in the management company is 1-2 working days. And you can work in good weather.

Necessary conditions for high-quality repair of interpanel seams:

Dry weather, no rain or snow. (temperature can be any)

High-quality and necessary materials, depending on the type of building facade.

Roof access. (we will arrange it ourselves)

If mold forms in the corners and on the walls of your apartment, water seeps out, the wind is constantly blowing, this means that sealing and warming of interpanel seams has not been done in your house for a long time. This means that there are voids between the panels, which facilitate the penetration of cold air and water inside. How do developers close up the seams in panel houses? In the best case: a pipe of Vilatherm with a diameter of 40 mm with a seam depth of more than 300 mm, and a sealant is smeared on top. Thus, the interpanel seams remain empty. A thin layer of sealant will not save the cold, and when it cracks and from rain leaks.

Application of Vilaterm: myths and refutation

It would be possible to give only a dry list of the scope of Vilaterm, but it is more interesting to touch upon the advertising description from many sellers on the Internet and building stores, wholesale bases. Often, they are seriously exaggerated, pointing out non-existent advantages and qualities of the material. Therefore, it is worthwhile to additionally study the main advertising theses on the application and positive properties, as well as give them a true assessment, perhaps a refutation, comment on each separate point!

Wide application in construction, renovation and finishing works as a heat insulator, sealant and sound insulator. Yes, this is a perfectly true statement;
The material is used to exclude leaks from the outside into the interior through cracks and interpanel joints. In fact, Vilatherm only seals the seam, and therefore, as a waterproofing material, it works only partially. To ensure high-quality protection, a whole range of works will be required, using additional materials, for example, waterproofing mastic;
Crevices and cracks filled with Vilatherm become hydrophobic. The concept is rather vague, since it should be indicated, as in the previous paragraph, that only in complex application.Independently, the material, if it is not provided with additional protection with mastic, due to the influence of the atmospheric environment, will lose its properties - crumple and shrink, while passing more and more water;
Vilatherm removes mold and mildew, dampness from the walls. The material certainly does not have such properties. But as a warning of these problems, it works;
Thermal insulation of facades and walls. Vilatherm has certain thermal insulation properties. But it will not make the wall warmer when laid in interpanel seams. You can use it, but only for its intended purpose;
High-quality insulation and sealing of joints between reinforced concrete slabs in construction. This is indeed the case. One of the best modern sealing materials and representatives of insulation systems;
Noise isolation of the room. Minimal noise reduction from the outside when laying in a seam. But for high-quality sound insulation of a separate room or object, work is carried out with all structural planes - walls, floors, ceilings. Also, it is necessary to choose the right doors and windows;
Thermal insulation of pipes in private housing construction. If the combination of characteristics is permissible, then this type of work can also be applied by completing the external finishing of water supply or sewage pipes;
Vilatherm is suitable for sealing joints when installing window systems and doors. A true statement, the foamed elastic tourniquet does an excellent job with such tasks;
Vilatherm in work with floating floors, dry screed device. Yes, the material is suitable for the installation of a damper zone around the perimeter, sealing. But more often a foam tape of a similar structure is used. It all depends on the choice of craftsmen at the place of work;
Furniture production - as form-building elements. Perhaps, but the application is not widely developed;
Insulation of old wooden windows, doors, any structural openings. Maybe! And in this area, the material has long proven itself well;
Car repair - noise insulation of car and truck bodies. True statement!

In fact, as mentioned earlier, in the construction industry and related areas, due to the characteristics and features of this product, it will be quite easy to find an application for it!

Description of heat-insulating cord Vilatherm

Insulation harness (or cord) Vilatherm environmentally friendly material and this lies in the fact that the blowing agent is a propane-butane mixture, and not freon, which until some point was used in the manufacture of these harnesses. It is quite important that when introducing fire retardants, the sealing cord Vilatherm becomes a more accustomed material for wooden housing construction.

Initially sealing insulation harness Vilatherm designed for sealing and warming the joints of concrete panels of prefabricated elements of building envelopes. Using the cord Vilatherm in the process of sealing and insulating cracks and joints, not only helps to reduce the consumption of used polyurethane or acrylic sealants, but also contributes to the formation of an elastic layer of dried sealant. The main form of production of insulation bundles Vilatherm there are cords of both solid section and sections with an internal hole. The presence of a hole does not reduce the physical and mechanical properties of the material.

This hole has a dual purpose.

Firstly, this is the saving of raw materials, which makes it possible to reduce the cost of its production, which affects the price of the bundle insulation. Vilatherm.

And secondly, this technological hole simplifies the installation of the Vilatherm sealing cord in a crack or expansion joint.

It is also important to note that VILATERM harnesses, according to the new GOST for window installation, have been tested and can be used in these units. The VILATERM harness is produced both with a solid section and with a hole.

How to work with Vilatherm

Internal work. When laying the sealant in the seams during internal work, its further protection is optional. Requirements for dry processes are minimal. It is enough to firmly press the cord into the cavity, trying to lay it straight, without twisting along the length. Such a device is allowed when sealing windows and doors, interpanel seams before plastering and finishing, when pouring floors. Bonding of material is possible!

Outdoor work. When sealing external seams with Vilatherm, additional foam and waterproofing materials are used. This requirement works in the field of sealing interpanel vertical and horizontal seams. On a loaded plane, as well as when installing a blind area, platforms and paths, the material is installed without mounting foam, on an adhesive base or liquid sealant, with additional mastic waterproofing!

Step-by-step instruction on technology:

The cord fits into the seam based on its dimensions. It is not recommended to stretch or compress the material along its length, as this will violate its density, leading to the material protruding from the seam;
For sealing joints of static structures, cracks in sites, heat-shrinkable seams of the pavement, material is used with a diameter tolerance of up to 40-50% greater than the width of the cavity. It should fit snugly into the mold;
Cutting the cord is done with a knife or scissors. It is not worth breaking the seal, as it has good tensile strength. By making an effort to break, you break the structure of the material;
It is possible to work with seams of any shape and length. Sealing at the joints of individual Vilaterm sections up to 10-20 mm;
After installing the cord in the mold, additional protection from moisture and ultraviolet radiation is mandatory!

Seams in a wooden house and sealants for their insulation

Quality acrylic sealants from several manufacturers are ideal for log work. Such a material for insulating seams does not contain harmful substances. Due to its elasticity, the sealant instantly masks cracks, seams and chips. It is resistant to UV rays and negative environmental irritants. A warm seam for a wooden house does not burst when the building shrinks, which is important for real estate located on soft ground. Apply sealant only after preliminary antiseptic work.

works with several and the highest quality sealants. For the attention of customers, the insulation of joints in two main types of insulating material:

"Accent". Sealing the seams of the house with such wood material is easy. The product is designed for long-term masking of cracks and cracks in wood. And also for warming and insulating joints between wooden beams.
Remmers. Such a sealant has a high level of resilience and elasticity. Subsequent staining of warm seams is allowed. It is resistant to external irritants, including adverse weather conditions.

Sealing of log seams in our company is carried out in the shortest possible time. offers the best prices, high service and quality assurance. The company has been operating for several years and therefore offers only high quality and free consulting at all stages of cooperation. Seams in a wooden house require processing. Call the professionals and save yourself the hassle.

Vilatherm and polyurethane foam: the difference in insulation and sealing of seams

In this comparison, you can work without tabular data, because there is a standard experience of masters, which shows that in almost any region, polyurethane foam, which is not protected by painting, plaster or mastic from the influence of the external environment, becomes unusable at the junction of the first and second seasons. Finally spoils and spills out after 2 years, in more suitable conditions - after 3 years.

Vilatherm and similar materials based on foamed polyethylene show more serious service lives in an unprotected environment - about 8-10 years. At the same time, there is minimal shrinkage, primary damage to the external structure, drying out of the material.

Using polyurethane foam or foamed polyethylene cord, the materials should be additionally waterproofed. But in the event of a violation of the protective layer, Vilatherm minimally absorbs moisture and temperature fluctuations, when the polyurethane foam begins to actively accumulate and pass water through itself into the interior. It remains to add here the conditions of negative temperature, and the sealing material is almost completely damaged, although the mastic protective layer is still more or less suitable externally!

With foam, internal damage is more likely. And the problem is that even when inspecting the building before possible preventive work, only an experienced craftsman will notice minimal damage and start working with the seams. If such a moment is missed, moisture will begin to accumulate inside, complementing the necessary conditions for the development of a pathogenic environment. And according to the first opinion, the insulated and sealed seam will already cause dampness and mold on the inner walls!

Working with Vilatherm is pleasant and simple, but most importantly, it is convenient and inexpensive. The sealing harness is available in different sizes, is on sale at almost any retail outlet, and costs from 3 rubles per running meter. Decent option at an affordable price!

The sequence of work when insulating interpanel seams

The technological process of repair, restoration or primary insulation of joints in panel houses is as follows:

Dismantling of old materials that were used to insulate the seams.
Cleaning cracks from existing materials, dirt. At this stage, it is necessary to clean the surface as much as possible in order to ensure the subsequent maximum level of adhesion of the insulation to the surface, which will increase its service life.
Antiseptic surface treatment to exclude the formation of bacteria and fungi in the insulation, as they can lead to its destruction.
Filling voids with polyurethane foam.
Installation of insulation (as a rule, this is a special cord).
Application of polyurethane foam or mortar to the insulation.
Sealing the joint with bitumen mastic or special solutions.
Implementation of quality control of work for compliance with regulatory documents and customer requirements, signing an act of work performed and a warranty obligation.
