Wood sealant « Warm seam"can become the basis thermal insulation protection the buildings. Undoubtedly, there are other ways, but this one is the most convenient. If you have started to think about insulating your home, then you should resort to this technology. When making a comparison with the traditional system of thermal insulation of inter-crown gaps, which uses hemp, jute or flax batting insulation, it is worth noting that filling cracks in the inter-crown space with sealant increases the thermal resistance of the walls and reduces heat loss. If we're talking about about natural insulation materials, they are capable of allowing cold air, which significantly reduces the thermal resistance of log walls.

Consumer reviews about the effect

Warm joint wood sealant has many advantages. According to users, with its help you can achieve a comfortable indoor microclimate. Such thermal insulation makes the temperature and humidity conditions optimal, while saving energy, because there is no heat leakage from the inter-crown gaps. House heating costs are minimal.

Owners of private wooden houses they say that after thermal insulation work using the described technology, drafts disappear, log walls are not blown out during cold and damp weather. You can count on the material not being damaged by biological organisms. The gaps are sealed as much as possible, mold no longer forms in them, and insects do not penetrate inside.

If you use Warm Joint Wood Sealant, you can save money. According to buyers, they no longer have to invest additionally, which is required for periodic caulking. Among other things, you will end up with quite attractive walls, the joints of which will match the shade of the wood.

Reviews about the advantages of “Warm seam” over caulk

Previously, the insulation of wooden houses was often carried out using the caulking method, today this technology is replaced by a system called “Warm seam”. The latter technique has many advantages. For example, caulking walls is quite labor-intensive, and it must begin no earlier than a year after completion of construction. According to the owners of private houses, this cannot be called convenient. Among other things, the caulking process will need to be repeated regularly, since flax and moss are pulled away by birds, and the seams also increase due to shrinkage. Modern consumers emphasize that appearance the log house after completion of the caulking stage cannot be called attractive. Over time, the walls completely lose their aesthetic appearance.

Reviews on the characteristics of sealants for performing work using the “Warm seam” technology

Wood sealant “Warm Seam” is chosen by customers because it has many advantages. According to home craftsmen, these compositions are not at all afraid of temperature changes; harmful microorganisms and mold do not appear or develop on their surface. As practice shows, the described sealants are not affected by sun rays, and over time they do not lose their original color. According to buyers, sealants have high level adhesion to wood, they are characterized by elasticity, which is especially evident when the inter-crown gaps are compressed. This allows you to complete these works and forget about them forever. You can apply “Warm Seam” sealant for wood, which has only the most positive reviews, at any time of the year. At the same time, residents will not experience inconvenience such as dust, odor or noise. The house can continue to be used.

Features of using Neomid sealant

Wood sealant “Warm seam” “Neomid” has gained popularity among consumers; its use requires compliance with certain rules. For example, before final application it is necessary to caulk the seams, for which jute or flax tow. Then, using a spatula, a sealant is applied to the surface, which makes it possible to insulate the resulting gaps using a combined method.

The warm seam technology has become widespread today and is successfully used for insulating wooden houses along with traditional caulking. Modern method thermal insulation is different high speed execution of work and takes place without noise, dirt and dust. One-time insulation with sealant, which is not afraid of moisture, mold, or insects, is enough for long years services. But all this is possible only if professionals in their field take on the work. Self-sealing seams can result in consequences for owners big problems. If you decide to make a warm seam for wooden house, the cost of sealing work per linear meter in Moscow, you will learn from the article.

The seams of the log house are sealed after the main shrinkage of the house has passed, no earlier than a year and a half after the completion of construction. As a result of wood deformation, voids and cracks appear between the crowns of the logs, which are then sealed with suture waterproofing.

Warm seam sealant is elastic acrylic composition. When hardened, it forms a film that can take any shape. The film can stretch and shrink and goes through all deformation processes together with the wood without cracking.

Insulation log house outside is carried out subject to the following conditions:

• Wood moisture content is not higher than 20%;
• dry weather without precipitation;
• The average daily air temperature during the sealing period exceeds 10 degrees.

The cost of sealing the seams of a wooden house

Insulation of a log house is carried out in several stages:

1. Surface preparation.
2. Cord routing.
3. Sealing.
4. Seam processing.

Each of the listed stages is mandatory and has its own specifics. Price linear meter sealing consists of the totality of all work performed. You can see how much each job costs in the price list.

Preparatory work

Surface preparation is very important stage, preceding sealing. An uncleaned surface prevents the sealant from adhering to the wood, which can cause a poor seal. The surface where the sealant will be applied must be cleaned of dirt and dust, and the old paintwork must also be removed.

The cost of the work depends on how the surface is cleaned. Cleaning can be done manually using a coarse metal brush or with a grinder.

Filling joints with cord

After cleaning the surface, a special polyethylene cord is placed in the joints between the logs, which performs several functions at once:

• allows logs to contract and expand freely without affecting the sealant;
• fills the seam with an even line, allowing the sealant to lie neatly and evenly;
• serves to preserve heat;
• allows you to reduce the cost of sealant.

The price per linear meter of cord sealing is included in the total cost of house sealing work.

Sealing seams with sealant

Sealing of inter-crown seams with sealant is carried out using a gun. The insulation is applied on top of the laid cord with a thickness of 4-6 mm. In some cases, it is necessary to reseal the external seams. The cost of applying sealant is calculated per linear meter.

If there are longitudinal and end cracks on the logs, in order to repair them, craftsmen carry out restoration. The cost of this service depends on the complexity and size of the defect.

Seam processing

In order for the joints to acquire a beautiful and neat appearance, craftsmen still need to work on them. It is necessary to remove any remaining compound and smooth out the seam. special tool. Then the seams are rubbed and undergo several stages of sanding. The cost of each stage of work is calculated separately.

What else affects the cost of work?

Besides the cost compulsory work, sealing prices also include:

• the cost of sealant, polyethylene cord and other necessary materials;
• equipment delivery costs;
• workers' compensation.

The price of the work also depends on the lumber from which the house is built. The cost of sealing a log house made of chopped logs is more expensive than the cost of insulating a house made of rounded logs or timber. Insulate the log house manual cutting much more complex than a house made of smooth lumber. The price formation is also influenced by the diameter of the log: the smaller the diameter of the lumber, the lower the cost per linear meter of sealing.

Defrosting is carried out without additional heating at temperatures up to +22ºС. Keep out of the reach of children. Shelf life 24 months from the date of manufacture.

Ecologically pure wood has long been considered excellent material for building a house. Huts or log cabins built from wood are good because you can breathe easily in them. In summer, such buildings do not heat up much like brick or stone houses, and it’s comfortable to be in them even in the heat, and in frosty winters, wooden walls retain heat well, not letting the cold into the room. For these reasons, many people prefer to build their dachas and country houses made of wood.

However, along with the above advantages, wood also has many disadvantages. Thus, under the influence of natural factors it is subject to deformation and damage. Moisture causes wood logs to swell, and in dry weather they dry out. All this leads to the fact that cracks begin to appear between the crowns of the log house, through which winds and cold can penetrate into the house, and rain and dampness are the causes of rotting of the wood and its gradual destruction. But these processes can be prevented if the log house is insulated in a timely manner and the joints of the logs are sealed. The salvation of the home is the high-quality sealing of the seams between the crowns. What materials are best to use for sealing walls and how to properly seal seams in a wooden house?

Is it worth caulking a wooden house?

The most famous inter-crown insulation materials are considered to be moss, hemp and tow. The advantages of these natural materials are resistance to temperature fluctuations, bactericidal and mold fungi, low thermal conductivity, good moisture absorption. But fewer and fewer people who build log houses use these materials to seal seams in a wooden house. Why has the demand for moss, tow and hemp decreased so much?

The process of caulking cracks and spaces between the crowns is quite labor-intensive and lengthy, because you need to carefully and evenly plug them natural materials using a chisel. The walls cannot be caulked immediately after the construction of the log house, since it will not take much time to shrink it. less than a year, and during this time moisture can already begin its destructive work. The disadvantage of caulking tow and moss is the fact that this process will need to be repeated more than once. The thing is that birds love to “steal” materials from people to build nests. By pulling moss and tow out of cracks and joints, they disrupt the integrity of the seal and cause wooden log house a sloppy, disheveled look. Winds also worsen the appearance of walls. As for material such as hemp, it is susceptible to attacks by moths, which, through their activity, harm the seal.

Knowing these disadvantages natural insulation materials, manufacturers of building materials produce more advanced sealants to improve the quality of insulation of all cracks and seams of a wooden house. What are they good for? modern insulation materials walls?

How to insulate walls with tape tow and linen rope?

One of the improved sealants is natural tow in rolls. It is made from flax, which is first well combed on carding machines, then the fibers are polarized and turned into a 15 cm wide ribbon. Next, the fibers are cleaned of various impurities. The result is excellent noise and thermal insulation material with good waterproof properties.

Unlike ordinary tow, tape tow is easier and more densely placed between joints; although it is soft, it is not so brittle.

Thanks to the naturalness of the material, the walls of the log house breathe well and do not rot. Sealing seams from ribbon tow more durable, and it is not easy for birds to pull it out of the cracks. Stacked roll material, as usual, along the crowns and along their edges using a chisel or a special caulk spatula, carefully tucking the edges of the tape inside each seam and crack. The result is a reliable seal between the logs, and the appearance of the log house is quite attractive.

A house insulated with linen rope looks even more beautiful. This sealing of seams is called rope sealing. Three-strand flax rope is used as insulation, which is secured to the seam with staples or nails. Needed for work following materials and tools:

• tape measure or ruler;
• scissors;
• linen rope;
• hammer;
• short nails;
• metal staples;
• brush;
• wood impregnation.

The purchased linen rope is placed along the line of the inter-beam seam and every 15 cm, after pulling it well, a bracket or nail with a small head is driven into the beam. At the corners of a wooden house, the distance between fasteners may be smaller. To make the rope sealing of seams look aesthetically pleasing, when driving in nails or staples, perform the following action: first, open the strand of rope a little, then hammer in the fasteners, tuck the rope itself to the wall of the log house and tighten it. The strand is closed, and the staple or nail head is hidden underneath from prying eyes.

When sealing the seams with natural linen rope is completed, care should be taken to ensure its safety for a long time. To do this, you need to take a protective impregnation for wood and carefully treat all the rope edges with it. You can perform this procedure by impregnating the log walls themselves at the same time. Despite the fact that the process of sealing all the seams of a wooden house is quite long, it is simple and can be done without the help of other people. Rope insulation of seams in a wooden house is highly reliable, perfectly protects the log house from moisture and gives the structure an unusual but attractive look.

​Which is better - caulk or warm joint for a wooden house?

What is better, what is more practical and cheaper, what will last longer? Traditional caulk, which in one form or another has been used for centuries or qualitatively New Product- sealant? Let's try to figure it out.

The article was prepared by specialists of the ARKHANGELSKY DOM company, taking into account almost 20 years practical experience in the construction, finishing, operation and repair of wooden houses. We offer our Customers only high-quality production services finishing works, we advise on the choice of materials and technology, we save from future mistakes, unprofessionalism and negligent attitude of coven teams...

Traditionally, caulk is used to insulate inter-crown joints in a log house.

Basically, caulking is caulking or plugging the cracks between logs with caulking material. Moss, jute, different types tow and more modern materials, for example, flax wool. Linen wadding practically does not accumulate moisture, effectively fills voids in inter-crown joints, and has good warmth and soundproofing properties. At home, flax wool can add zest to the decorative component or emphasize the chosen style.

Not so long ago, another technology for insulating wooden houses began to gain popularity - sealing using the “Warm seam” system. In the junction between the logs they lay sealing cord made of foamed polyethylene, which provides heat and moisture protection to the seam. This insulation prevents the sealant from adhering to the wood at the third point, thereby ensuring it correct work for compression and tension. We told you about the warm seam and the technology for its application earlier... You can always find this information on our website in the article section.

The main question that Customers ask is which is better? What is more practical and cheaper, what will last longer? Traditional caulk, which in one form or another has been used for centuries, or a brand new product - sealant? Let's try to figure it out.

Log caulking

As for caulking, this is a time-tested method of insulating inter-crown joints and connections between. It is mainly used for houses made of rounded logs and hand-cut logs. It is hardly possible to caulk an entire house from a profiled sheet, although individual elements, for example, the gaps between the wall and the casing, the corners of cuts and the insertion points of beams and rafters can be insulated. High-quality caulking avoids loss of thermal energy, protects seams from moisture and blowing and, in the end, does not violate environmental harmony.

Unfortunately, one of the main disadvantages of caulking is durability. Without elasticity or any damping properties, it can last 4-5 years at best. Deformation movements of logs during the subsequent process force inspection and repair of the seam between the crowns. The tightness of the junction gradually weakens, blowing occurs and moisture enters the seam. The linen wool is no longer tightly packed, but simply hangs and, as a result, becomes good material for nests of agile birds.

The low price of the material itself, environmental friendliness and tribute to tradition are perhaps all that caulk can be of interest to today.

Sealing using the “Warm seam” system can be suitable for any wooden house. There have been cases when even houses made of laminated veneer lumber were covered with sealant. Of course, this is extremely rare, but we have come to the first advantage of sealant - versatility. Its versatility is also evidenced by the variety of types of sealant on the market. The most popular sealants for log houses are on acrylic base.

The next advantage is the service life. About 20 years according to most manufacturers. True, here, I would not say unequivocally. It is very important what sealant you chose, how the surface was prepared and what hands applied it. Only good adhesion to the existing surface, the elasticity and resilience of the material allow you to level natural movements wooden structures and maintain the first-class appearance of the building. Today, we can highlight premium acrylic-based sealants from Remmers and Perma-Chink. Also, sealants based on MS polymers have proven themselves well.

Despite high cost, first of all, the material itself, the use of sealant allows you to seal cracks in and on long term prevent any blowing and moisture from getting between the logs, justifying the initial investment over the years.

What to choose?

Our customers often ask us – what would you choose for yourself?

Oddly enough, we chose for ourselves combined option. Protection from bad weather and cold with the help of sealant on the outside, warmth and comfort with caulk on the inside.

And the decision is yours...
