Technical characteristics of glue

Typically, this insulation is installed from the outside of the structure. Because of this, when installing mineral plates on the exterior of a house, the glue used for these plates must be able to endure covered natural elements. To find out if it works with mineral wool or not, you must read the instructions beforehand. Qualities that this material requires from the adhesive composition:

• Flexible property, it depends on the quality of plasticizers and modifiers in the composition. Flexibility helps to avoid cracks on the surface;
• High degree of adhesion to mineral wool and base;
• Vapor permeability so that condensate on the surface is not formed from the inside;
• Resistance to low -temperature effects, external use implies the effect of negative temperatures. For this reason, the adhesive solution should calmly tolerate the cold and the process of thawing with an increase in temperature. There are gluing stories that can be used in frost;
• The pace of drying should not be long so that you do not have to spend too much time on repair work;
• The period of preservation of the properties of the diluted solution. The longer you can use glue after breeding, the better, then the master can prepare a sufficient amount of solution for processing larger area;
• The permissibility of creating thick layers in areas where the surface irregularities are present. In the rest of the even zone, layers will be made thinner. The indicator of the flow rate of the product is important here, good compositions do not exceed the number of 4-6 kg/m2 in terms of consumption.

Polyurethane is most commonly used as the foundation for mineral wool insulation glue; it is also widely used for facade finishes on quartz sand and cement.

The ability to withstand the natural elements that are coated during installation on the house’s facade is necessary for glue used for mineral plates on a basalt basis.

Highlight a high level of adhesion, plasticity of the coating, frost resistance. The average consumption is 5-6 kg/m2;

The ability to be used for thermal insulation and for both indoor and outdoor work sets the Ministry of Plutes EK Thermex adhesive apart.

The instructions specify that it may be used for internal work, but it is typically chosen for external work.

What glue for mineral wool is best suited

You can select universal tools that work with various kinds of insulation materials from those that are available for purchase for this purpose. Either glass-type instruments or specialized instruments made as glue for basalt insulation. There are three types of funds produced: liquid, foamy, and dry.

Dry mixes are put into dependable bags; the mixture’s volume can vary from five kilograms to twenty-five kilograms. The following elements are added to these insulation tools for glass wool or basalt bases:

• Synoptic resin;
• Quartz sand with cement;
• Plasticizing substances;
• Other fillers to give the best qualities to the solution.

The composition needs to be diluted with water before use in order to create a paste-like solution for application. When there are irregularities and a lower-quality surface, it is recommended to purchase them because a layer of glue can block them. Some varieties are appropriate for use in cold weather. They list the following as benefits of dry mixtures:

• High clutch indicator with materials;
• The seam is flexible, extensible;
• Resistance to mechanical loads;
• Vapor permeability;
• Resistance to moisture, frost and heat;
• Environmental friendliness.

The composition needs to be diluted with water before use in order to create a paste-like solution for application.

Because they are ready to be applied, liquid agents are simpler to use. However, keep in mind that they harden quickly after being opened, so it’s best to give up on picking tiny containers. In addition, their price is greater than that of dry mixtures, and their range of use is already limited. Not to be used on smooth surfaces.

Only a wooden and brick base can be utilized with liquid solutions.

Polyurethane is used to make glue foam for mineral wool. Cylinders are used for the release; they can purchase a suitable gun or use a special nozzle for application. Convenience for surface distribution designates a similar form. The funds are available to everyone, and among their benefits are the following aspects:

• Speed ​​and ease of application;
• Create a layer that is also distinguished by a heat -insulating property;
• Can be used for cold and high humidity;
• Safe composition;
• Water resistance;
• Vapor permeability;
• Long term of application.

For mineral wool to provide safe and efficient insulation in building projects, adhesives are essential. These adhesives are made expressly to attach mineral wool—a common insulation material composed of slag fibers or melted rock—to a variety of surfaces. They guarantee that the insulation stays in place and continues to function effectively over time by offering strong adhesion, moisture resistance, and durability. The thermal and acoustic qualities of mineral wool can be improved by using the proper adhesive, increasing the comfort and energy efficiency of buildings.
