Is glass wool suitable as insulation? Characteristics and properties in the insulation of a private house: Overview + Video

Glass wool or stone wool has been used for a long time; this is a rather old technique for insulating a house, and yet it is used in real time and in almost all construction companies. The effectiveness of mineral glass wool can be said to be partially irreplaceable. This insulation material can not only insulate large rooms and houses, but also small apartments. [contents ]

But not only glass wool can be used in thermal insulation, but also alternate with any other material that you will increase noise insulation and heat preservation.

The cheapness of glass wool has always attracted a large number of buyers as it is cheap and of high quality.

Do not forget that glass wool, like many other insulation materials, has favorable and unfavorable sides.

Glass wool cannot replace the complete thermal insulation of your home. But there are many more positive qualities of this material than disadvantages.

Glass wool features

As mentioned above glass wool - this is one and not expensive building materials. Since the cost is not high, it is made from industrial waste.

About half of the raw materials are cheap components.

Glass wool consists of the following components: soda, dolomite, limestone, sand. The main component of knauf and other glass wool is cullet. The production and components of glass wool have not changed for several decades, which means that the primary components are most suitable for it.

Positive and negative properties of glass wool

• Relatively low price category.

  This is one of the attractive factors. At one time, we get cost savings and a decent heat saving effect in your homes. Also, do not forget that glass wool can be easily replaced in unforeseen cases. Moreover, glass wool can be combined with other thermal insulation materials.

• Easy to install.

  Steklov has the greatest ease of installation in houses and apartments in comparison with many other modern thermal insulation materials. This not only saves you time, but also allows beginners to take up the installation process. Do not forget that any work must be equipped with equipment. Since glass wool is not 100% safe.

• Easy transport .

  The shape and elasticity of the material allows it to be moved from place to place. First of all, it is convenient for people who deliver goods. And even sometimes the owners have to transport the material to their home.

Disadvantages of fiberglass materials

• 

  First of all, the material is very soft and deformable. This is the most serious drawback affecting the performance of glass wool.

  Not a small space inside the material is not always good.During the cold season, warm air inside the material will move to the cold edge. Therefore, whatever this is, it is necessary to lay glass wool in several layers so that there is a dense structure.

• Glass wool has a rather large water absorption. Very often, water gets on the material due to improper installation in walls and ceilings.

  If the material resists water absorption well, then nothing bad will happen. It is also required to pay special attention when the installation of glass wool takes place in horizontal places or before installation it is required to create a high-quality moisture-resistant layer. Serious damage to the glass wool can appear if the structure on which the wool is attached can shift or bend. Since the material can be easily deformed (stretch, tear, crush).

The right choice of quality glass wool

Exists a huge number of types of glass wool, it should be chosen not only by the price of the category, but also by the manufacturing technology.

First of all, it is worth paying attention to the manufacturer in order to acquire a truly high-quality product. You can find the goods of newly emerging companies, this does not guarantee that the price relates to quality. It is better to use a product of a well-known company. Do not be afraid to overpay a little, as there will be more chances that you will purchase better quality glass wool. It is not so difficult to purchase a quality product since there are a huge number of worthy manufacturers.

External insulation of the house with glass wool

• First, let's prepare the walls for the main process . We clean the surface of the walls from plaster, dirt, etc., so as not to create a layer that will retain moisture between the cotton wool and the wall.
• The next step is to fix the waterproofing. As mentioned above, we do our best so that moisture does not in any way get into the layers between the walls and the cotton wool.

  Waterproofing is an almost ordinary film that prevents moisture from entering the material. When using a wooden base (lining, etc.), we advise you to attach the oilcloth with a stapler to the boards. Just cover the joints between the films with tape. Pay special attention so that the cotton that you will be installing is not wet.

• Next, we make a base for fastening glass wool. Often they take wooden blocks (50x50), which we attach to the wall with less than the same distance. The distance depends on the length of the material you are using. Subtracts 3-4 cm from this value. All this in order to attach the material as densely as possible to the created cells.

• • Glass wool installation - just push the material between the bars. We do everything carefully without sudden movements, since the material is soft enough and can tear. Torn glass wool will not be as effective in thermal insulation.
  • After dismantling the glass wool, a vapor barrier must be attached. This is actually the same as the first layer, but with some refinements.

    The vapor barrier is attached to wooden blocks with a stapler. Again, there will also be joints that need to be hidden with tape.
