What kind of wool to use for soundproofing

In this article we'll talk about sound-proof wool, its types, advantages and disadvantages. Soundproof wool has long gained its popularity and has established itself as a reliable material. Only it is used always in combination with the following materials: sound insulating plate (Ponstar, ZIPS) or membrane (Tecsound). Why is it important to use in combination with other materials? Wool by itself, the material is porous and light, and in the matter of soundproofing you need mass, multiple layers, different structure and density of materials. Due to this and the effect of reducing air noise. Wool in such constructions add to the overall result of 5-6 dB. It has many air pores, due to this there is the effect of sound absorption.

Let's look at what is wool and what is its feature:


Basalt – the name speaks for itself, the basis of basalt wool is a fiber of small length. Themselves the fibers are arranged randomly, and this is due to the effect of sound absorption. It belongs to the group of incombustible materials (NG), which speaks about fire safety. Select the wool you need with a minimum thickness of 50 mm. you Also need to pay attention to the density, it should be at least 30-45kg/m3. Vata conceived comes in the form of plates, this allows you to easily install it in a standard frame. The service life is up to 50 years. She also has hydrophobic properties, i.e. does not absorb moisture. The plates are easily cut, if necessary. It was so popular that it is applied completely in all areas of public and industrial use.

Its disadvantage is that it does not fray, prickly, and when mounting it is necessary to protect hands and eyes. Another significant disadvantage of wool is the fact that in the production process of the connective substance for gluing of basalt fibers is formaldehyde resin. As the phenol to be treated to hazardous materials it is not recommended to use cotton wool in residential buildings.

Wool from name it is clear that it is made from glass staple fibers. This wool also belongs to the category of non-combustible (NG). It also comes in slabs or rolls and is used for soundproofing walls and ceilings framing system. This material has a high chemical resistance. Disadvantage of this wool is a low density (15-17 kg/m3) of material which are insufficient for sound insulation, wool flaking, dusty, and can irritate the skin and respiratory tract.

In our time, progress does not stand still, and experts have developed wool from staple fiber, which will satisfy all the requirements for good sound insulation. This wool is not itchy, not flaking, and you can almost equate it to health. She is white and it means that with the gluing of the fibers is not used formaldehyde resin. It is safe and non-toxic. Making the choice in favor of such wool, pay attention to the thickness and density. The thickness should be 50-100 mm, the optimal density of 30-40 kg/m3.

Also fiber is treated with water-repellent composition. It differs high durability. An example of such wool is let Somanet-EKO. It does not crumble, does not break, it does not itch the body and hands. And in the process of bonding of the binder fibers were acrylic, which speaks of 100% sustainability. Following all of the above, this kind of wool can be used in any environment, even in institutions. The only minor drawback will be the cost. It's a little higher than that of basalt.

Ecowool is a relatively new type of cotton in the market. It is made from natural ingredients, often a mixture of polyester and cotton. At first glance it seems that this is the ideal option, but an integral part of the wool is flammable. Of course, this wool is completely safe, hypoallergenic and mount it can be "bare hands", as they say. The thickness of this wool 35-55mm. At the same density 40kg/m3 would be sufficient. It is supplied in slabs or in rolls. Often this kind of wool is only used in private construction, by the way, its price is slightly lower than the glass wool.

Well, I told you about the main types of wool and their knowledge about them. You know the advantage and disadvantage of each type. What to choose? Decide from those qualities that are a priority for You. Someone in the pursuit of price, some for quality or safety.

In any case, the choice is yours, but if you have any questions I will gladly answer them by phone:
