Rockwool insulation is one of the high-tech and environmentally friendly materials. It is widespread in various fields. Due to the quality of the material, it is safe to use it even at home. Raw materials have a state certificate of conformity.
What is Rockwool
Rockwool is a company that specializes in the production of insulation and sound insulation materials. The brand began its existence in 1936. It was previously registered in Denmark and for the first time carried out the sale of some minerals: coal and rocks.
Heat insulators are made on the basis of stone wool with the addition of wool. The finished raw materials are of high quality and durable. The company has its own research center, which develops unique technologies for the production of insulation. This material deserves the confidence of consumers in more than 18 countries around the world. In the early 70s, the ROCKWOOL brand spread throughout the regions of the Russian Federation.
Scope of application
Due to its characteristics, the insulation has a wide range of applications.
- In construction. Use the material in this direction of steel primarily due to the positive properties and effectiveness of thermal insulation. Raw materials are used in the design of partitions and ceilings in multi-storey buildings. It is also used during the construction of cottages and private houses under a concrete screed.
- In ventilated and non-ventilated façade systems. For the construction of partitions, which in the future will be formed under the facade, they try to use ROCKWOOL of sufficient elasticity. They carry out not only thermal insulation, but also a load-bearing function.
Internal thermal insulation of the house with Rockwool insulation - When insulated from the inside. For this purpose, Rockwool basalt insulation is used. It is mounted indoors on the walls facing the street. Also suitable for insulating other types of partitions, ceilings, floors of any design.
- For the roof. Most often it is used for insulation when organizing a roof. Shows excellent performance properties for thermal insulation of mansard rooms and attics.
- ROCWOOL in the form of cylinders has special properties for thermal insulation of pipelines of any size. Such material is securely attached to the surface of the line, does not require preliminary preparation.
The assortment includes Rockwool slabs of increased rigidity. They are suitable for insulating wall wells, as well as for insulating street walls or interfloor layers.
When calculating the amount of material for thermal insulation, it is necessary to be guided by the SNiP standards and the formula R = R1 + R2 + R3.
Material specifications
The thermal insulation material is famous for its good performance characteristics, thanks to which it deserves its attention.
- A reduced level of heat transfer, due to which up to 70% of the generated heat is stored in an insulated room.
- Fire resistance. Minwata Rockwool is distinguished by high fire safety, as it belongs to the class of non-combustible materials. Withstands temperatures up to 1000 degrees.
- Resistant to deformation.During installation, the material may change slightly in the structure, however, it recovers very quickly in shape. It is not subject to mechanical stress, therefore it is boldly used to insulate facades.
- Good vapor permeability. The material slightly absorbs moisture, but nevertheless tends to accumulate it. Therefore, along with the insulation, it is also necessary to install waterproofing.
- Soundproofing. One of the important properties that Rockwool stone wool has. This quality is achieved due to the presence of a layer of air - all sounds are kept in the middle of the composition.
Technical characteristics of Rockwool thermal insulation may differ depending on the model and its intended use.
Advantages of ROCKWOOL mineral wool
Thermal insulation from the ROCKWOOL brand is able to compete with various materials for a similar purpose due to the following qualities:
- The material is environmentally friendly despite the presence of formaldehyde salts in it. All of them go through the polymerization process, so they do not evaporate toxic gases during operation.
- It is a barrier against impact noise and vibration. Almost all street work (in particular, construction) is not audible indoors due to the unique structure of the heat-insulating layer.
- Basalt slabs practically do not get wet if they are installed correctly. Even the smallest violation of the integrity can cause a regular accumulation of moisture, which will result in the appearance of dampness and fungus on the walls. Therefore, it is important to properly fix the material to the surface.
- The durability of the insulation. Achieved due to the random placement of mineral wool fibers.
Also, users note the quick and convenient installation of the heat insulator due to its unique structure.
Rockwool slabs cut perfectly without losing their original geometric shape.
Insulation safety
Stone-based cotton wool is considered one of the safest. The manufacturer was the first to receive the well-deserved certificate of conformity EcoMaterial Green. Therefore, the insulation is available for use in any children's, medical and public institutions. Such material is of exclusively natural origin; safe resins are used for the bond.
Due to the presence of a European certificate, it is acceptable to use Rockwool thermal insulation in a residential environment. There is no phenol in the structure. For this, the manufacturer used high-tech solid state binder resins.
Mounting methods
To properly install the thermal insulation on the outer wall of the house, you can use special fixing dowels or a suitable adhesive base.
Application of special glue
If high-quality and expensive cotton wool is used to insulate the facade, it is necessary to use glue of the appropriate quality. There must be a sufficient amount of binder in this material. Depending on the weight of the insulation mats, it is necessary to select a fixing base. To fix the heat-insulating sheet to the surface, you must:
- pre-print the material and leave for a day;
- find the wrong side and mark the places for the location of the glue;
- stir the glue according to the recipe indicated on the package;
- make strokes around the perimeter with a spatula;
- gently lift the material and fix it in the right place on the wall.
It is better not to combine different adhesives with each other in order to save money. This will negatively affect the tightness of the heat insulator.
Fastening to construction dowels
First, you need to determine what structure the basalt wool has, since there are different types of dowels for solid and porous insulation. To calculate the number of fastening tools, you need to know the height of the building and the wind zone. Approximately 6 dowels are required to install one square meter of insulation.
There is always more wind force in the corners of buildings. Here you need to more reliably fix the insulation layer. Therefore, the number of fasteners must be increased.
A combination of glue and dowels is often practiced when installing insulation for Rockwool walls.
Rockwool Scandic and Standard
Both materials from the same company are widely used and have a lot of advantages. However, they differ in several properties.
| Characteristic | Rockwool Scandic | Rockwool Standard |
| Compressibility | 30 % | 60 % |
| Packaging | Compact sealed blocks | Plastic wrap |
| Dimensions (edit) | 800-1200 mm | 1000 mm |
| Thickness | 50-200 mm | 50-100 mm |
| Application | Doesn't take a lot of stress | For unloaded structures |
| Availability of XL modifications | there is | not |
Both heaters do an excellent job with their tasks, so the demand for the material is increasing every year.
Calculation of the required quantity and thickness
When organizing the insulation of buildings, it is imperative to calculate the number of mats that will be required for airtight cladding. Not least is the thickness of Rockwool insulation. When calculating, they are guided by the following components:
- climatic conditions;
- required indoor temperature;
- type of premises: house, apartment, room, basement;
- the height and length of the walls.
It is mandatory to indicate whether the structure has additional layers: concrete floors, beams or blocks.
If it is necessary to insulate an area of 90 sq. m in Crimea, where the climate is rather mild and warm, the volume of material should be 13.5 cubic meters. Be sure to use a stock of 1-1.5 cubic meters.
