Choosing a sealant for sound insulation

Sound insulation in modern homes has become particularly relevant not only because of the desire to negate the noise from the street or from the next room, but also because of the increasing need for silence, especially among residents of megalopolises. A cheap, fast and effective solution to this problem can be a sealant. This article will tell you what sound insulation sealant is and how to choose it correctly.

In fact, the original sealant was used as a thermal insulation coating, but over time it became more associated, and then completely found its use only as a sound insulation coating. This is due to the fact that there are more effective insulating materials.

As a rule, noise insulation sealants are used for wooden houses. They are applied to the gaps at the joints of the logs on both sides - outside the wall and on the inside of the room.

It is easy to apply a sealant, it is only important to do this carefully and pre-protect the eyes and hands:

• The first and important step is the preparation of the surface for applying the composition. To do this, the surface is cleaned of visible debris and degreased.
• Sticking adhesive tape along the seam edges. After completion of the work, it is deleted.
• The very stage of applying sealant. It is important to remember that if the surface is at an angle or it is vertical, then the seam is filled from below. Apply the mixture gradually and try to fill the entire space evenly.
• Spread the mixture evenly. For this, a sponge or a small spatula is most often used.
• The last stage - remove the tape, and remove excess mixture.

Before choosing sealants for sound insulation, first of all you need to knowthat they have different composition and texture for use on different surfaces. It is for this characteristic that sealants are divided into several types.

• Acrylic. Such a composition becomes hard after drying, suitable for surfaces that are subject to constant mechanical stress.
• Silicone. This species is the most common. After drying, it retains its elasticity, therefore it does not crack with time, it is suitable for all surfaces and to any sizes of seams.
• Other sealants. Most often, this type refers to assembly foam. It is used for sound insulation and vibration absorption.

When purchasing it is important to inspect the packaging. It must be complete, without damage, with an airtight lid. The sealant has a special composition that requires certain storage rules (not higher and not lower than 15 degrees) and a short shelf life.

One of the most popular types of these products in the domestic market is the sealing compound. "Vibrosil". It creates an acoustic vacuum, so it is actively used when installing sound-insulating structures.Consumers really like the fact that this sealant can be used for joints of various widths and lengths. Its high vibroacoustic properties are especially noted.

This sealant does not cause corrosion of metals, withstand moisture and temperature drops from -40 to +150 degrees. Construction professionals use Vibrosil on various materials: metal, wood, glass, concrete, brick and even enamel. Of the inconveniences, it is noted that the sealant is capricious when applied, as well as the fact that it is best to work in a ventilated room.

As for Western products, the analogue of "Vibrosila" can be considered a sealant "Maksforte". It is made from raw materials delivered from Belgium, and has good sound insulation properties. It becomes elastic after drying, so it easily tolerates changes in temperature and humidity.

The composition of the sealant includes anti-fungal and anti-mold additives. Customers like that the composition is very light and pleasant to use: the sealant quickly sticks to the surface, dries almost instantly, does not have a pronounced smell.On average, one tuba of this composition will cost 300 rubles.

Returning to domestic products, you can separately note the sealant Soundguard It is designed to seal small gaps, irregularities and defects during construction. According to the buyers, this sealant does not provide complete sound insulation, but it is excellent as a supplement to the sound insulation coating.

In addition to the above-mentioned products, the brand's products also received good reviews. Green glue (American product), which is represented by several sealants for various surfaces.

Whatever product you choose, it is important to remember that applying a sealant does not eliminate the problem of noise, but only helps to solve it more effectively and efficiently. Soundproofing sealant is used only in addition to the soundproofing coating in the cracks of floors, ceilings and walls of the room.
